ETHE & GBTC (Grayscale) Frequently Asked Questions

It is no doubt Grayscale’s booming popularity as a mainstream investment has caused a lot of community hullabaloo lately. As such, I felt it was worth making a FAQ regarding the topic. I’m looking to update this as needed and of course am open to suggestions / adding any questions.
The goal is simply to have a thread we can link to anyone with questions on Grayscale and its products. Instead of explaining the same thing 3 times a day, shoot those posters over to this thread. My hope is that these questions are answered in a fairly simple and easy to understand manner. I think as the sub grows it will be a nice reference point for newcomers.
Disclaimer: I do NOT work for Grayscale and as such am basing all these answers on information that can be found on their website / reports. (Grayscale’s official FAQ can be found here). I also do NOT have a finance degree, I do NOT have a Series 6 / 7 / 140-whatever, and I do NOT work with investment products for my day job. I have an accounting background and work within the finance world so I have the general ‘business’ knowledge to put it all together, but this is all info determined in my best faith effort as a layman. The point being is this --- it is possible I may explain something wrong or missed the technical terms, and if that occurs I am more than happy to update anything that can be proven incorrect
Everything below will be in reference to ETHE but will apply to GBTC as well. If those two segregate in any way, I will note that accordingly.
What is Grayscale? 
Grayscale is the company that created the ETHE product. Their website is https://grayscale.co/
What is ETHE? 
ETHE is essentially a stock that intends to loosely track the price of ETH. It does so by having each ETHE be backed by a specific amount of ETH that is held on chain. Initially, the newly minted ETHE can only be purchased by institutions and accredited investors directly from Grayscale. Once a year has passed (6 months for GBTC) it can then be listed on the OTCQX Best Market exchange for secondary trading. Once listed on OTCQX, anyone investor can purchase at this point. Additional information on ETHE can be found here.
So ETHE is an ETF? 
No. For technical reasons beyond my personal understandings it is not labeled an ETF. I know it all flows back to the “Securities Act Rule 144”, but due to my limited knowledge on SEC regulations I don’t want to misspeak past that. If anyone is more knowledgeable on the subject I am happy to input their answer here.
How long has ETHE existed? 
ETHE was formed 12/14/2017. GBTC was formed 9/25/2013.
How is ETHE created? 
The trust will issue shares to “Authorized Participants” in groups of 100 shares (called baskets). Authorized Participants are the only persons that may place orders to create these baskets and they do it on behalf of the investor.

Note – The way their reports word this makes it sound like there is an army of authorizers doing the dirty work, but in reality there is only one Authorized Participant. At this moment the “Genesis” company is the sole Authorized Participant. Genesis is owned by the “Digital Currency Group, Inc.” which is the parent company of Grayscale as well. (And to really go down the rabbit hole it looks like DCG is the parent company of CoinDesk and is “backing 150+ companies across 30 countries, including Coinbase, Ripple, and Chainalysis.”)

How does Grayscale acquire the ETH to collateralize the ETHE product? 
An Investor may acquire ETHE by paying in cash or exchanging ETH already owned.

Where does Grayscale store their ETH? Does it have a specific wallet address we can follow? 
ETH is stored with Coinbase Custody Trust Company, LLC. I am unaware of any specific address or set of addresses that can be used to verify the ETH is actually there.
As an aside - I would actually love to see if anyone knows more about this as it’s something that’s sort of peaked my interest after being asked about it… I find it doubtful we can find that however.

Can ETHE be redeemed for ETH? 
No, currently there is no way to give your shares of ETHE back to Grayscale to receive ETH back. The only method of getting back into ETH would be to sell your ETHE to someone else and then use those proceeds to buy ETH yourself.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
Why are they not redeeming shares? 
I think the report summarizes it best:
Redemptions of Shares are currently not permitted and the Trust is unable to redeem Shares. Subject to receipt of regulatory approval from the SEC and approval by the Sponsor in its sole discretion, the Trust may in the future operate a redemption program. Because the Trust does not believe that the SEC would, at this time, entertain an application for the waiver of rules needed in order to operate an ongoing redemption program, the Trust currently has no intention of seeking regulatory approval from the SEC to operate an ongoing redemption program.
Source: Redemption Procedures on page 41 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
What is the fee structure? 
ETHE has an annual fee of 2.5%. GBTC has an annual fee of 2.0%. Fees are paid by selling the underlying ETH / BTC collateralizing the asset.

What is the ratio of ETH to ETHE? 
At the time of posting (6/19/2020) each ETHE share is backed by .09391605 ETH. Each share of GBTC is backed by .00096038 BTC.
ETHE & GBTC’s specific information page on Grayscale’s website updates the ratio daily – Located Here
For a full historical look at this ratio, it can be found on the Grayscale home page on the upper right side if you go to Tax Documents > 2019 Tax Documents > Grayscale Ethereum Trust 2019 Tax Letter.
Why is the ratio not 1:1? Why is it always decreasing? 
While I cannot say for certain why the initial distribution was not a 1:1 backing, it is more than likely to keep the price down and allow more investors a chance to purchase ETHE / GBTC.
As noted above, fees are paid by selling off the ETH collateralizing ETHE. So this number will always be trending downward as time goes on.
Source: Description of Trust on page 32 of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
I keep hearing about how this is locked supply… explain? 
As noted above, there is currently no redemption program for converting your ETHE back into ETH. This means that once an ETHE is issued, it will remain in circulation until a redemption program is formed --- something that doesn’t seem to be too urgent for the SEC or Grayscale at the moment. Tiny amounts will naturally be removed due to fees, but the bulk of the asset is in there for good.
Knowing that ETHE cannot be taken back and destroyed at this time, the ETH collateralizing it will not be removed from the wallet for the foreseeable future. While it is not fully locked in the sense of say a totally lost key, it is not coming out any time soon.
Per their annual statement:
The Trust’s ETH will be transferred out of the ETH Account only in the following circumstances: (i) transferred to pay the Sponsor’s Fee or any Additional Trust Expenses, (ii) distributed in connection with the redemption of Baskets (subject to the Trust’s obtaining regulatory approval from the SEC to operate an ongoing redemption program and the consent of the Sponsor), (iii) sold on an as-needed basis to pay Additional Trust Expenses or (iv) sold on behalf of the Trust in the event the Trust terminates and liquidates its assets or as otherwise required by law or regulation.

Grayscale now owns a huge chunk of both ETH and BTC’s supply… should we be worried about manipulation, a sell off to crash the market crash, a staking cartel? 
First, it’s important to remember Grayscale is a lot more akin to an exchange then say an investment firm. Grayscale is working on behalf of its investors to create this product for investor control. Grayscale doesn’t ‘control’ the ETH it holds any more then Coinbase ‘controls’ the ETH in its hot wallet. (Note: There are likely some varying levels of control, but specific to this topic Grayscale cannot simply sell [legally, at least] the ETH by their own decision in the same manner Coinbase wouldn't be able to either.)
That said, there shouldn’t be any worry in the short to medium time-frame. As noted above, Grayscale can’t really remove ETH other than for fees or termination of the product. At 2.5% a year, fees are noise in terms of volume. Grayscale seems to be the fastest growing product in the crypto space at the moment and termination of the product seems unlikely.
IF redemptions were to happen tomorrow, it’s extremely unlikely we would see a mass exodus out of the product to redeem for ETH. And even if there was incentive to get back to ETH, the premium makes it so that it would be much more cost effective to just sell your ETHE on the secondary market and buy ETH yourself. Remember, any redemption is up to the investors and NOT something Grayscale has direct control over.
Yes, but what about [insert criminal act here]… 
Alright, yes. Technically nothing is stopping Grayscale from selling all the ETH / BTC and running off to the Bahamas (Hawaii?). BUT there is no real reason for them to do so. Barry is an extremely public figure and it won’t be easy for him to get away with that. Grayscale’s Bitcoin Trust creates SEC reports weekly / bi-weekly and I’m sure given the sentiment towards crypto is being watched carefully. Plus, Grayscale is making tons of consistent revenue and thus has little to no incentive to give that up for a quick buck.
That’s a lot of ‘happy little feels’ Bob, is there even an independent audit or is this Tether 2.0? 
Actually yes, an independent auditor report can be found in their annual reports. It is clearly aimed more towards the financial side and I doubt the auditors are crypto savants, but it is at least one extra set of eyes. Auditors are Friedman LLP – Auditor since 2015.
Source: Independent Auditor Report starting on page 116 (of the PDF itself) of the “Grayscale Ethereum Trust Annual Report (2019)” – Located Here
As mentioned by user TheCrpytosAndBloods (In Comments Below), a fun fact:
The company’s auditors Friedman LLP were also coincidentally TetheBitfinex’s auditors until They controversially parted ways in 2018 when the Tether controversy was at its height. I am not suggesting for one moment that there is anything shady about DCG - I just find it interesting it’s the same auditor.
“Grayscale sounds kind of lame” / “Not your keys not your crypto!” / “Why is anyone buying this, it sounds like a scam?” 
Welp, for starters this honestly is not really a product aimed at the people likely to be reading this post. To each their own, but do remember just because something provides no value to you doesn’t mean it can’t provide value to someone else. That said some of the advertised benefits are as follows:
So for example, I can set up an IRA at a brokerage account that has $0 trading fees. Then I can trade GBTC and ETHE all day without having to worry about tracking my taxes. All with the relative safety something like E-Trade provides over Binance.
As for how it benefits the everyday ETH holder? I think the supply lock is a positive. I also think this product exposes the Ethereum ecosystem to people who otherwise wouldn’t know about it.
Why is there a premium? Why is ETHE’s premium so insanely high compared to GBTC’s premium? 
There are a handful of theories of why a premium exists at all, some even mentioned in the annual report. The short list is as follows:
Why is ETHE’s so much higher the GBTC’s? Again, a few thoughts:

Are there any other differences between ETHE and GBTC? 
I touched on a few of the smaller differences, but one of the more interesting changes is GBTC is now a “SEC reporting company” as of January 2020. Which again goes beyond my scope of knowledge so I won’t comment on it too much… but the net result is GBTC is now putting out weekly / bi-weekly 8-K’s and annual 10-K’s. This means you can track GBTC that much easier at the moment as well as there is an extra layer of validity to the product IMO.
I’m looking for some statistics on ETHE… such as who is buying, how much is bought, etc? 
There is a great Q1 2020 report I recommend you give a read that has a lot of cool graphs and data on the product. It’s a little GBTC centric, but there is some ETHE data as well. It can be found here hidden within the 8-K filings.Q1 2020 is the 4/16/2020 8-K filing.
For those more into a GAAP style report see the 2019 annual 10-K of the same location.
Is Grayscale only just for BTC and ETH? 
No, there are other products as well. In terms of a secondary market product, ETCG is the Ethereum Classic version of ETHE. Fun Fact – ETCG was actually put out to the secondary market first. It also has a 3% fee tied to it where 1% of it goes to some type of ETC development fund.
In terms of institutional and accredited investors, there are a few ‘fan favorites’ such as Bitcoin Cash, Litcoin, Stellar, XRP, and Zcash. Something called Horizion (Backed by ZEN I guess? Idk to be honest what that is…). And a diversified Mutual Fund type fund that has a little bit of all of those. None of these products are available on the secondary market.
Are there alternatives to Grayscale? 
I know they exist, but I don’t follow them. I’ll leave this as a “to be edited” section and will add as others comment on what they know.
Per user Over-analyser (in comments below):
Coinshares (Formerly XBT provider) are the only similar product I know of. BTC, ETH, XRP and LTC as Exchange Traded Notes (ETN).
It looks like they are fully backed with the underlying crypto (no premium).
https://coinshares.com/etps/xbt-provideinvestor-resources/daily-hedging-position
Denominated in SEK and EUR. Certainly available in some UK pensions (SIPP).
As asked by pegcity - Okay so I was under the impression you can just give them your own ETH and get ETHE, but do you get 11 ETHE per ETH or do you get the market value of ETH in USD worth of ETHE? 
I have always understood that the ETHE issued directly through Grayscale is issued without the premium. As in, if I were to trade 1 ETH for ETHE I would get 11, not say only 2 or 3 because the secondary market premium is so high. And if I were paying cash only I would be paying the price to buy 1 ETH to get my 11 ETHE. Per page 39 of their annual statement, it reads as follows:
The Trust will issue Shares to Authorized Participants from time to time, but only in one or more Baskets (with a Basket being a block of 100 Shares). The Trust will not issue fractions of a Basket. The creation (and, should the Trust commence a redemption program, redemption) of Baskets will be made only in exchange for the delivery to the Trust, or the distribution by the Trust, of the number of whole and fractional ETH represented by each Basket being created (or, should the Trust commence a redemption program, redeemed), which is determined by dividing (x) the number of ETH owned by the Trust at 4:00 p.m., New York time, on the trade date of a creation or redemption order, after deducting the number of ETH representing the U.S. dollar value of accrued but unpaid fees and expenses of the Trust (converted using the ETH Index Price at such time, and carried to the eighth decimal place), by (y) the number of Shares outstanding at such time (with the quotient so obtained calculated to one one-hundred-millionth of one ETH (i.e., carried to the eighth decimal place)), and multiplying such quotient by 100 (the “Basket ETH Amount”). All questions as to the calculation of the Basket ETH Amount will be conclusively determined by the Sponsor and will be final and binding on all persons interested in the Trust. The Basket ETH Amount multiplied by the number of Baskets being created or redeemed is the “Total Basket ETH Amount.” The number of ETH represented by a Share will gradually decrease over time as the Trust’s ETH are used to pay the Trust’s expenses. Each Share represented approximately 0.0950 ETH and 0.0974 ETH as of December 31, 2019 and 2018, respectively.

Updated FAQs for newcomers

TL:DR: Don't bother mining if you want to get rich yo. You're way too late to the party.
Welcome to the exciting and often stressful world of bitcoin! You are wondering what looks like a once in a lifetime opportunity to get rich quick. Of course you guys probably heard about this "mining" process but what is this?
Simply put, a bitcoin mining machine that performs complicated calculations and when deemed correct by the network, receives a block which contains 25 bitcoins (XBT). This is how bitcoins are generated. So your brain instantly thinks, "Holy shit, how can I get on this gold rush?"
Before you proceed further, I would like to explain the concept of mining further. Bitcoin is limited 21m in circulation. It is coded to release a certain number of blocks at a certain time frame, ie: this year the network will release close to 500,000 bitcoins. What this means is that the more people (or specifically the amount of mining power) mine, the less each person gets. The network tries to keep to this time frame through the process of difficulty adjustments which makes the calculations harder and this happens every 2 weeks. So every 2 weeks, you get less bitcoins with the same hash rate (mining power) based on what the difficulty changes are. Recently, the changes have been pretty staggering, jumping 226% in 2 months. You can see the difficulty changes here.
Now, why are these changes so large?
A bit of a simple history. Bitcoin's algorithm runs on SHA-256. This algorithm can be solved using many hardware, from CPU to GPU and dedicated hardware (Application Specific Integrated Circuits). When bitcoin first started, mining on CPU was a trivial process, you can pretty much earn 50 XBT (the block size then) every few hours between Q1 and Q2 of 2010.
In late 2010, due to the difficulty increase that is reducing the effectiveness of CPU mining, people started to harness GPU mining. Only AMD GPU's architecture design are better optimized for bitcoin mining so this is what the community used. Immediate improvements of more than 10x was not uncommon.
In time of course, GPUs reached their limit and people started to build dedicated. In the same vein as the CPU to GPU transition, similar performance increase was common. These ASICs can only perform SHA-256 calculation so they can be highly optimized. Their performance mainly depends on the die size of the chips exactly like CPU chips.
In general, think of bitcoin mining's technological advancement no different to mining gold. Gold panning (CPUs) vs pickaxes (GPUs) vs machinery (ASICs) and we are still in the ASIC mining race.
ASIC mining started with ASICMiner and Avalon being first to the market, both producing 130nm and 110nm chips. The technology are antiquated in comparison to CPUs and GPUs which are now 22nm with 14nm slated for Q1 next year by Intel but they are cheap to manufacture and with performance gains similar to the CPU to GPU transition, they were highly successful and popular for early adopters. At that point in time since there were less competing manufacturers and the low batch runs of their products, miners became really rich due to the slow increase in difficulty.
The good days came to an end mid August with an unprecedented 35% increase in difficulty. This is due to existing manufacturers selling more hardware and many other players coming onto the market with better hardware (smaller die). Since die shrinking knowledge and manufacturing process are well known along with a large technological gap (110nm vs 22nm), you get an arms race. Current ASIC makers are closing in on our technological limit and until everyone catches up, the difficulty jumps will be high because it is just too easy to get a performance increase. Most newer products run at 28nm and most chips are not well optimized, so it will be around another 6 to 9 months before we see hit a hard plateau with 22nm or 14nm chips. The estimated time frame is because manufacturing chips at 22nm or 14nm is a more difficult and expensive task. In the meantime most manufacturers will probably settle at 28nm and we will reach a soft plateau in about 3 months.
Now, you might ask these questions and should have them answered and if you have not thought about them at all, then you probably should not touch bitcoin until you understand cause you are highly unprepared and probably lose lots of money.
No. If you have to ask, please do not touch bitcoin yet. You will spend more on electricity cost than mining any substantial bitcoin. Seriously. At all. A 7990 would produce a pitiful 0.02879 XBT (USD $14 @ $500/XBT exchange rate) for the next 30 days starting 23 Nov 2013 at 35% difficulty increase.
And if you think you can mine on your laptop either on a CPU or GPU, you are probably going to melt it before you even get 0.01 XBT.
Probably not because you probably forgot that GPUs and CPUs produce a ton of heat and noise. You can try but I see no point earning < $20 bucks per month.
No, because your machine will probably not mine as much as buying bitcoins. This situation is called the opportunity cost. While you can still make money if XBT rise in value, it is a fallacy.
IE: if you start mining on 1 Dec 2013, a KnC Jupiter running at 450Gh/sec (KnC lies as not all chips run at 550Gh/sec) will yield you a total revenue of 9.5189 XBT with a profit of 0.7859 XBT in profit by 30th Jan 2014 at a constant difficulty increase of 35%. The opportunity cost is: 8.5910 XBT @ USD $580/XBT with USD $5,000 which is the cost of a KnC Jupiter. This is the best you can earn and it's a bloody optimistic assumption because:
The only circumstances where you will earn money is when XBT exchange rates is so high that it makes the opportunity cost pales in comparison. Unfortunately this is not the case. If XBT stabilized at 900/XBT today (20 Nov 2013) then we might have a good case.
The risk is just generally not worth it. Unless you have at least a hundred thousand and can make a contract with a manufacturer for a lower cost, do not bother. Just wait until the arms race is over then you can start mining.
Okay, go buy an AsicMiner USB Block Erupter. They are cheap and pretty fun to have.
Sure, just read the answer below on who NOT to go for. You are doing bitcoin a service by securing the network and you have our (the users') gratitude.
You can check out the manufacturers and their products below along with a calculator here.
If you still insist on buying, do not to go for BFL. Their track record is horrid and borderline scammish. KnC fucked up a lot with defective boards and chips. Personally, I think CoinTerra is the best choice.
Alternatively, you can go on the secondary market to buy a delivered product. You can get a better deal there if you know how to do your "return on investment (ROI)" calculation. Personally, I will go for a 45%-50% difficulty increase for the next 3 months for my calculations and a 2% pool fee.
However, most products on ebay are sold at a cost much higher than it should. bitcointalk.org is a cheaper place because everyone knows what are the true value is so you will find less options. If you are unclear or need assistance, please post a question.
I actually do not use any of the pools recommended to the left because I think they lack features.
My favourite is Bitminter (Variable fees based on features used; max 2%). It has all advanced features for a pool, very responsive and helpful owner on IRC. Variable fees is good for those who do not need a large feature set, even with all features turned on, it is still cheap.
Eligius (0% fees) has high value for money but lacks features. It has anonymous mining which might be attractive to certain subset of people but not for others. Many other community member and I disagree highly with the opinions of the owner on the direction of bitcoin. I do use his pool for now but I do so only because I share my miners with a few partners and anonymous mining allows us to monitor the machines without using an account. Bitminter uses only OpenID which is problematic for me.
BTC Guild (3% fees) is another big pool and is fully featured and does charge a premium for their fees. That said, they are the most stable of the lot. I do use them but do so only because my hoster uses them for monitoring. I try not to use them because a pool with a very large hash rate (they are the largest) presents a large vulnerability to bitcoin's network if compromised.
All of them pay out transaction fees.

Bitmex Options Shenanigans

This post is a look at the recently released Bitmex Up and Down contracts and the lack of clarity around them and the issues that has caused. There will be a little bit of maths and options terminology, but I'll do my best to try to keep it simple.

Background and Contract Specification

Bitmex released the Weekly Up Contract (XBT7D_U110) for live trading on the 30th Apr, with the Weekly Down contract (XBT7D_D90) coming later, on the 14th May. Both contracts are essentially European style options contracts (with the addition of a knock out price for the Down Contract), which settle weekly on Fridays.
This was an interesting development on the part of Bitmex. They made 2 posts on their blog (1, 2) explaining the situation. Although, the blog posts weren't posted on the website announcement feed nor (to my knowledge) on their twitter, so many people (including myself) missed them.
While the contracts came with the usual Bitmex explanation of specification and example, what struck me was the fact that:
  1. Throughout the whole contract guide there wasn't a single reference to "Options", despite that being the nature of the contacts.
  2. Traders aren't allowed to short them - "Only the BitMEX anchor market maker can be net short".
(Full screen shots of the guides as of 15th May 2018 can be found at the bottom of the article)
We now have the issue of a contract that many traders will have no idea how to price, that is consequently trading over 10x higher than fair value, and only the market makers are allowed to short.

Options pricing and Fair Value

The Up contract is equivalent to a European style options call, while the Down contract is a slightly modified European options put. Options contracts give the buyer the right (but not obligation) to buy (call) or sell (put) at the given strike price on the settlement time (European style).
European style options contracts are generally prices using the Black-Scholes model, which is used to calculate the fair price of a contract along with measures of its sensitivity to various factors such as underlying price and volatility (known as Greeks).
Options Fair Pricing vs Current Pricing
At time of writing the Up contract (XBT7D_U110) last trade price is 0.00300 BTC (~$25.57), with 2.89 days until expiry. The Bitmex historical volatility index is currently 54.15%, strike price is $9500 and Bitcoin is $8530.
The black-scholes calculator suggests that the fair price is actually $1.916. And that is the calculation for a 1 Bitcoin contract. Where as the Bitmex contracts represent 0.1 XBT each. Making the fair value $0.1916, rather than the current $25.57. Which is a bit insane.
What if we use a higher value of volatility for our calculations, will the price be a bit more reasonable? Similar contracts trading on a different exchange have an implied volatility of ~75% annualised. This gives a fair value of $1.351 for each Up contract.
I've also occasionally seen Bitcoin volatility reach up to 120% or higher. This value still gives a fair value of $7.870.
In other words, even by the craziest stretch, the Bitmex contracts are trading way higher than their fair value - and only the Bitmex designated market makers are allowed to short.

Options profit outlook

Now, what if the contracts were trading at fair value, what is the probability that the options would actually expire "In the money" (payout not zero).
One of the "Greeks" calculated under the black-scholes model, Delta, is generally used as a measure of exposure to the underlying asset, but can also be used as a probability that the option will expire in the money.
The absolute of Delta (non negative value) gives said probability. A call contract with Delta 0.75 has a 75% chance of expiring ITM. A put contract with a delta of -0.3 has a 30% chance of expiring ITM.
Probability of expiring In the Money
So, what are the chances of our Up and Down contracts expiring ITM? The Up contract's ticker is "XBT7D_U110", meaning that it expires every 7 days and its strike is placed at 110% of the trading price at the start of the trading period.
Again looking at the Bitmex volatility index at 54.15%, the Delta of this contract over 7 days comes to 0.1087, only an 11% chance of expiring in the money. 75% volatility gives Delta at 0.1933 and 120% gives Delta 0.3119. Not the best bet however you look at it.
For the Down contracts its even worse, with Delta being -0.07458 (7.458%), -0.1431 and -0.2367 for 54.15%, 75% and 120% volatility respectively.
The likelihood that any of these contracts actually pays out any money is rather stacked against the trader. And, as I've mentioned before, only the designated market makers are allowed to short these contracts to collect the price premium.

Are Options ever worth it?

Options trading is a wide and very mathematical discipline to master. When contracts are traded fairly (with reasonable pricing and without restrictions) options trading can be very profitable and allow all sorts of novel trades, such as betting on volatility.
However, in its current state, I personally wouldn't touch the Bitmex Up and Down contracts with a 10 foot pole. They are over priced and restricted from the ability to short. I have seen Bitmex as a generally reputable exchange in the past, however situations like this make be question that assessment.

Contract Guide Screenshot

I tried to archive the Bitmex contract guides with both archive.fo/ and archive.org/web/, however neither worked, so I used web-capture.net/ for screenshots instead. The full screen shots can be found here: Up Contracts, Down Contracts.

I'm also happy to take constructive criticism and amend the post if necessary.
edit: Thanks to happy__hippo for pointing out the Bitmex posts about the contracts. I've amended the article to reflect this.

Is it better to add to Position Margin when you're close to liquidation or buy more contracts?

Lets say I'm 2x long with 1 XBT at $10,000 which makes the liquidation price about $6700. What would make the liquidation price lower, using the "Position Margin" option to add another 1 XBT, or open another 2x long with that 1 XBT at a little above $6700($6800ish). Common sense says Position Margin but just want to make sure. And is there a way to calculate the new liquidation price before hand if I decide to keep buying contracts near my liquidation price? Thinking about just placing stop orders right before each liquidation.
Here's what I'm trying to do.
using $50,000, I want to open a 1 XBT 2x long. I believe Bitcoin will eventually go to 50k+ in the next bull run but so I'm willing to keep adding money to my position to keep from getting liquidated. Obviously if I keep "buying contracts" vs adding to Position Margin, I will have more money if/when price goes back up, but just trying to do the math and see which option makes more sense.

EDIT: I guess there's also the risk of your stop order not executing? So that's one disadvantage to trying to buy more contracts right before liquidation?

How-to & FAQ for holding Bitcoin and Ethereum in an RRSP/TFSA

A few months ago I came across a way to hold crypto in my RRSP/TFSA and have been answering questions about how to do that in comments, DM's, and Skype consults. I figured it would be helpful to put together one big comprehensive FAQ. Cryptocurrency is treated as a commodity by the CRA and you must pay capital gains taxes on any profits if held outside a TFSA. If bitcoin goes to $1m as some are predicting, the Canadian government is going to be taxing a huge windfall in capital gains taxes.
BACKGROUND
Bitcoin & other crypto cannot be held directly in a RRSP/TFSA, and there are no eligible ETF's in North America yet. However, the ETN COINXBT which trades on the Stockholm Stock Exchange in Sweden (Nasdaq Stockholm) is eligible.
ABOUT COINXBT
COINXBT holds bitcoin directly and its price per share is based on a 0.005 multiple of the current bitcoin price.
For example, if the current price of bitcoin is $10000USD, a share of COINXBT will be worth $50USD (ie: $493 Swedish Kroner)
Company's website and full prospectus at: https://xbtprovider.com/
Price quote / chart: https://www.bloomberg.com/quote/COINXBT:SS
HOW-TO TRADE
Only some Canadian brokerages allow you to trade on eligible international exchanges in your TFSA. Some do not.
Typically placing trades on international exchanges online is not an option and must be made over the phone broker-assisted at a much higher cost than typical North American securities.
CANADIAN BROKERS
I've called pretty much every brokerage to inquire if international securities can be held in a TFSA and what the fee is to transact. You may want to call yourself to see if policies have changed, but here's a summary:
Not available, or not available in RRSP/TFSA:
FAQ's
Are you sure it's legal? I'm quite sure it's illegal.
Who is your broker? CAD account?
How do I make a trade once I'm ready?
How do I calculate the number of shares to trade to max out my TFSA?
Market or Limit order?
When can I trade? Is it only possible to make the trade while the Swedish market is open and the TSX are open at the same time? Or can you place the order at any time of day?
Which number did you use to contact the brokerages?
What happens when there is a fork?
What about other cryptocurrencies?
How is the price of COINXBT determined?
Why not just buy GBTC?
Why can't I place a trade online myself?
Feedback
If you've managed to get crypto into your RRSP/TFSA in any other ways than listed above please do leave a comment and I'll update the post. Thanks!

Why I Am Holding Litecoin (LTC)

I would like to share why I am holding Litecoin (LTC) and why I classify it as a triple AAA asset. (Triple AAA is the highest rating an asset can receive.) There are only 3 assets that are currently classified in my book as triple AAA assets. (Bitcoin, Litecoin and Ethereum) Remember this is my personal opinion and you should always do your own research and come up with your own assessment before investing.
Created by Charles Lee in October of 2011, Litecoin is a scrypt-based digital currency. Now I could ramble on about Litecoin stats and the pros/cons compared to Bitcoin but that won't get us anywhere. Just because we have another crypto-currency doesn't necessarily mean it's competitive to Bitcoin or any other asset for the matter. I believe Litecoin has already achieved a status quo that would likely give it a 'permanent' place in crypto. With that said, I would expect Litecoin to continue to grow for decades and perhaps even centuries.
When you look at the typical asset in the market it generally consists of startups, experiments and hobbies. Even larger organizations like Ethereum, Ripple and NEO are likely to plateau when the market cap reaches the hundreds of billions or even near a trillion dollars. But what about assets like Bitcoin and Litecoin? If an organization or company can reach hundreds of billions or even a trillion in market cap, where would that put a currency/commodity? And what if that commodity is supported by the worlds largest financial institutions?
You have probably heard the saying 'Litecoin is the Silver to Bitcoin' and 'Bitcoin is digital gold' which honestly is probably not all that far from the truth. It has been said that in order for Bitcoin to achieve the same market cap as Gold, it would have to achieve a market cap of over $7 trillion.. Will that be the case? Nobody knows.. But if Litecoin is the Silver to Bitcoin, then how high could the market cap of Litecoin actually get?
When your talking about a currency/commodity with limited supply, especially ones like Bitcoin and Litecoin, there really is no 'known' limit to how high it can grow. (This is unprecedented territory.) With massive financial firms like Goldman Sachs and Fidelity looking to treat crypto as investment vehicles, the future seems very bright for AAA assets.
In partnership with Coinbase, Fidelity implemented on its website the option to display holdings in Bitcoin, Litecoin and Ethereum. - CNBC Aug 9th
Goldman Sachs is reportedly investigating into the plan of launching a cryptocurrency trading platform to provide sufficient liquidity towards institutional and retail traders. “In response to client interest in digital currencies, we are exploring how best to serve them in the space,” - Goldman Sachs Oct 1st, 2017
Now let's not get ahead of ourselves.. Nobody can say for certain that 'Litecoin' will make investors wealthy... However we can take the best calculated risks to ensure we are reliably correct. Looking at the overall picture, without a doubt I feel Litecoin is clearly around for the long-term. And when I say long-term I don't mean a few years, I mean there's a good chance Litecoin will be around for decades. How many asset's out there can you say with confidence will be around for decades? There aren't many...
“Some of you might be wondering: Why am I here today? I’m here because I love this stuff... all that the future might hold.” - Abigail Johnson, CEO Fidelity
So the biggest question I suppose would be, 'What makes Litecoin so special compared to the other cryptocurrencies?' Well to answer that question let's list some highlights.
Looking at Litecoins market cap it is sitting at around $5.5 billion USD. Now i'll just speculate a little bit here.. But I believe the majority of Litecoins market cap comes from massive financial institutions and not just the typical investor. These unknown entities whom have invested billions into Litecoin, are likely the same people planning to bring Litecoin to mainstream investors. Keep in mind we are extremely early in the crypto and everyone is getting in position, even mainstream itself. In addition, I believe the average investor has overlooked Litecoin and the focus has been more or less on Bitcoin/Altcoins.
Understanding the risks
Of course with any investment there are always risks. In the event Litecoin doesn't make it into the mainstream investment channels, then I think it would become a collectors coin long-term rather than a currency/commodity. Aside from BTC, If you are invested in any other digital currencies (not companies) then this is a risk worth noting. (I may cover this topic in a future post.)
This was a difficult post to write because there was a lot to say and not a lot of ways to say it. I am sure there will be a handful of people who will disagree with this post, but as always.. this is just my opinion. The bottom line is, bitcoin might be popular and grabbing a lot of attention, but bitcoin is not the only currency/commodity that is going to make major investors, firms and brokers wealthy.
Regards,
BTC2018

📌What is Cryptocurrency?

📌What is Cryptocurrency?
👉1. Definition of Cryptocurrency As a kind of digital currency (also called virtual currency), cryptocurrency is a medium of exchange that uses cryptography to ensure the security of financial transactions and digital assets. Unlike the traditional currency or fiat, cryptocurrency is no longer issued and managed by central bank. Instead, it is generated from a decentralized and distributed ledger system, typically called blockchain, by calculating and solving some math problems. In other words, the process of cryptocurrency production is called mining. Here is an example of Bitcoin mining. 👉2. Current Transaction Modes for Cryptocurrency Similar to fiat currency, cryptocurrency is also tradable. There are 3 popular transaction modes for cryptocurrency on most crypto exchanges around the world. 1) Fiat to Crypto Trading You can use fiat currency to purchase cryptocurrency in crypto exchanges. Before that, you have to do KYC in the exchange platform, and adding your debit card or other payment methods. Then, you can choose to buy BTC, ETH, LTC or any other with fiat. 2) Crypto to Crypto Trading Transaction between cryptocurrencies means that you can use BTC to buy ETH, LTC, EOS and more. In fiat to crypto transaction, it uses fiat to price a kind of cryptocurrency. But in crypto to crypto trading, for example, BTC's current price is used to price another crytocurrency. 3) Cryptocurrency Leverage Trading In leverage trading, also called crypto futures trading, cryptocurrency holders can leverage their existing amount of tokens/digital assets to enter a larger trade. That means you must deposit the minimum amount of BTC, ETH, LTC, etc. as margin to open a position. Then, you can open long or open short, and choose 5x, 10x, 50x,etc. #Bexplus #BTC #cryptocurrency #crypto#btcnews

Examining the Accuracy of Mark Price Data on BitMEX Futures

The Importance of Mark Price
For those who trade Bitcoin futures, the mark price is absolutely critical.
Mark price is what determines the risk management of your position by the exchange. Meaning that when you get liquidated due to a price going against you, it is because the Mark Price has crossed the threshold for margin call.
Defining Mark Price
But what exactly makes up the mark price? On OKCoin, this is done via "mark to market", i.e., the last price traded is what traders' P&L and liquidation risk are marked to.
On BitMEX, they have a reasonably complex (not mathematically, but in how many components it has) formula, which they post publicly here
It uses a combination of BTC/USD Spot Index (which they calculate as 50% BitStamp, 50% GDAX) and the depth of orderbook (i.e., liquidity on the exchange).
In technical terms, they compute this with an "Impact Mid Price" which computes the average between Impact Bid and Impact Ask prices. These are derived from computing the average fill price of 10 BTC order value in either direction. (This 10 BTC value is only for XBT series contracts, which I will be focusing on).
Then, this "Impact Mid" price premium versus the index is computed and discounted by the time out to expiry.
Script to check BitMEX mark price calculations
I have written a Python script that performs these calculations manually based on the orderbook data from BitMEX and bitstamp/gdax API's.
You can download it here: https://github.com/Whalepool/BitMEX-Mark-Price/ from Whalepool's GitHub
Example of discrepency
Let’s look at an example of a discrepency in BitMEX’s reported data for these.
Here you can see the current Quarterlies, XBTU17 orderbook side by side with the script's output manually computing it: http://i.imgur.com/GMBYC15.png
The main cause of the Mark price being skewed seems to be from the Fair Basis not being computed properly.
The impact bid, ask, and mid are more or less in line (although they should be exactly equal). However, the Fair Basis Rate, which is used to compute the Fair Value (or Fairbasis as it is calledi n the API), is skewed. The difference is not trivial either. Impact Mid computes fine, but the Fair basis Rate they report is 0.11, while the computed is 0.07. This is a significant deviation that pushes the fair basis higher and which inflates the level of the Mark Price, making shorts closer to liquidation than they would have otherwise been.
Possible Explanations
It's worth noting that BitMEX does not publish any historical data for Mark price. They do provide Index, but this is only one variable in a multi-variate formula for reaching the Mark Price, which is most important.
Initially, I thought this discrepency would be due to Hidden Orders (h/t to Mayvune for the idea), but BitMEX has said that hidden orders are not included: http://i.imgur.com/smKinXA.png
You can manually calculate from the visible orderbook screenshotted above and see that the Fair Basis was definitely not in line with the computation from the documented formula and the correct impact mid price.
Perhaps it is just a matter of timing? BitMEX says it is updated every 5 seconds, so maybe that doesn't seem plausible either.
Maybe setting it up on websocket or something would be closer?
Concluding Thoughts
Has anyone else noticed discrepencies in BitMEX's Mark Price data? Are there any other traders who have made an effort to verify the integrity of the components of the mark price?
Please, feel free to use the Python script above, do whatever you want with it, and see what data you come up with.
It is critical that we as traders have accurate transparent information. When trading high leverage derivatives, every tick counts on the mark price, and a small deviation can be the difference between catching a knife successfully and getting liquidated.
The BitMEX guys have done an excellent job developing a great platform with a risk management system that has successfully handled remarkable volatility. This post is not meant to be an attack on them, I think their exchange is one of the top in the space.

Bitfinex: Arthur Hayes estimates $3.42 million 6 months revenue - "better average employee compensation than Goldman Sachs"

Interesting blog post by Arthur Hayes, CEO of BitMEX.
In the last 6 months, 4.28 million Bitcoin were traded on Bitfinex (Bitcoinity). Assuming they net 0.20% per transaction (since they offer affiliate programs and some market makers trade for free) then we can estimate a top-line revenue of 8,560 XBT. At $400 per Bitcoin, that’s $3.42 million. Bitfinex has between 10 to 20 staff. Bitfinex wants the community to believe that they earn no profit. Or that on average employees make $342,000 per year (assuming 20 employees). That’s a better average employee compensation than Goldman Sachs.
Another interesting analysis:
Bitfinex is afraid of US-pound-me-in-the-ass prison, or a company-ending-fine from one of the many alphabet letter agencies in the US. The most likely scenario that a large amount of US customer funds were not taxed so that the fiction of segregated accounts could be preserved.
https://blog.bitmex.com/youve-been-buttfinessed/
Update
BitMEX updated the blog post
Bitfinex has about 25 employees. Bitfinex wants the community to believe that they earn no profit, or that their average employees make nearly $300,000/yr. That’s better average employee compensation than Goldman Sachs.
Edit: The above section has been amended given new information. BFX appears to have nearly 25 employees. The previous calculations were very rough and did not include overhead, which would reduce salary amounts, but also did not include altcoin or margin funding revenue, which would increase them. Our point – that salaries & overhead are very high or money is being intentionally withheld – still stands.

In depth BitMEX XBT contract analysis

MATH/WIDGETS SHOULD BE FIXED NOW
Hi all, have been trying out BitMEX lately, since I think Sam was on the Whale Club advertising a while back. So here is what I learned so far and my experience.
Their main bread and butter at BitMEX is the XBT future contract. It is a quanto future, which may not seem important at first, but in reality is very important. Lets take a look, from their XBT Series page.
The XBT chain of futures contracts allows investors to speculate on the future price of the Bitcoin / USD (XBTUSD) exchange rate. These are classed as Speculative contracts and feature leverage of up to 100x.
Ok, seems normal enough. And then...
Traders wishing to profit from an increase in the XBTUSD exchange rate will buy XBT contracts. The difference between where a trader buys the futures contract and where the XBTUSD exchange rate is on settlement day, multiplied by 0.00001 XBT, is the trader’s profit.
ok, fine. So what's a quanto?
The XBT futures contracts are considered quanto futures contracts. That is because the multiplier is in XBT while the contract is quoted in USD. Traders who measure their Profit and Loss (PNL) in Bitcoin terms will receive a linear payout. Traders who measure their PNL in USD terms will receive a non-linear payout.
USD Contract Value = Futures Price2 * 0.00001 XBT * Number of Contracts
Because the price is squared the return resembles that of a parabola. For bullish traders, the upside is better and downside is not as bad when trading the XBT futures contracts.
Whoa, sounds pretty cool. Better upside, and not as bad downside. Where have you been all my life?!
So I started spread-sheeting, and running some calculations of scenarios. I even made 2 graphing widgets on Wolfram Alpha to help calculate different scenarios. You can use them yourself here.
EDIT: Combined into 1 universal Widget now, enter - value for leverage to short
BitMEX XBT USD Profit/Loss Calculator Graph - Wolfram Alpha Widget
EDIT EDIT: updated Widget now shows breakeven bounds on graph for $0 profit, useful for shorting
BitMEX XBT USD Profit/Loss Calculator Graph - Wolfram Alpha Widget
So once I started graphing, I realized things were actually much more in depth then they seemed with Quanto contracts and overall profits. I'll give a quick overview here. I ran several scenarios with both long and short XBT, calculate profits in % USD and graphed them. So, y-Axis is % USD profit, so 1=100% profit, 2=200% profit, 3=300% profit, -2 = -200% profit. This may be confusing since they should have been labeled "multiplier" to be more accurate, my spreadsheet had it converted to % so 1.05 = 105% actually, but the graph makes it confusing. See the charts for yourself here
http://imgur.com/a/hYW7X
Initial response: Looking at the long chart, wow, pretty cool! I can run with very low leverage at 1x my position, and with a gain in 50 150 points up (from 350 to 400500), I earned about 100% return! So I double my money with 150 point move (which is only 42.8% of my initial position), without using any leverage. Downside doesn't look as bad since the slope levels out going left, the BitMEX Series guide was telling the truth. Ok, now lets look at short position (this is where things get a little Twilight Zone-ish).
Now, viewing the short graphed curves, this is much more interesting to me. Now, shorting here with the same leverage as before, 1x, will never ever return a profit. The blue curve never goes above 0, so at most you will break even with 0 price movement, and any price movement long or short you will also lose money. Welp, that doesn't look too appealing, why would anyone do that? Ok, lets raise the leverage. So now using double leverage (2x), if the price rises, I lose money, and if the price drops too much I lose money, however there now exists a zone between 175 and 350 (my entry) where there is a slight profit, maxing out at 260 expiry with a 50% ~20% maximum possible profit. Ok, lets look at higher leverage. Even using 800% leverage (8x), if the price rises I lose money, if the price drops too much I lose money. However, again, there is a zone between 50 and 350 (the strike) that is a profit zone, this time peaking at nearly 5.5 (550%) 3.5 (350%).
So, shorting XBT on BitMEX seems to be quite the conundrum.
So it seems like a pretty bad deal to short XBT on BitMEX. Why would anyone do this? Well, people normally wouldn't, but if you look at the actual prices for the XBT25H/7D/Quarterly/Semi, the prices are always above current spot price. This is the reason why, since shorting is a pretty bad deal, sellers have to be enticed with very good Strike Prices so the prices are usually always higher than spot. So the premiums usually range from .004% (or much higher sometimes) on the 24H, to up to 30% on the semi-annual sometimes.
However, another problem here, the liquidity is so low, you can't simply enter and exit most contracts beyond the daily. For example, right now, the spread on the semi-annual is basically 400 bid and 520 sell right now, so if you were to try to enter and exit today, you would have a 30% haircut just for playing because low liquidity.
So, my overall opinion of BitMEX now after learning how their system really works?
1) seems needlessly complicated the concept of having a quanto future since people are really worried about USD profit and loss of their Bitcoin asset. The quanto future process obfuscates this quite a bit
2) low liquidity on most contracts except the daily
3) Good website, good programming interface, easy to use interface, good helpful staff
4) XBT long has very strong upside while minimizing loss, XBT short is like a liquor store scratcher, you may win $20 bucks here or there but probably not :) Actually, the short almost reminds me of an options play, a short straddle to be exact, only rounded and not linear.
Love to hear feedback if my calculation were wrong or any other comments. Here is the formula used to calculate profits/loss. Formula should be fixed now
((1+((x-STRIKE)*(LEVERAGE/ STRIKE)))*x)/STRIKE -1 MULTIPLIER being negative means its short The result will give you for example 1.2 = 120% profit. 
Edit: Math is off, gunna look at it later and fix it.
Edit 2: Math fixed on graphs and widget.
Edit 3: 1 single widget now works for long or short, simply enter negative leverage amount for a short

I have a some questions about margin trading.

In case I didn't make it clear I'm doing all of this on BitMEX
So I've only recently got into the whole world of bitcoin exchanges, and I've found out about bitmex's option of up to 100x leverage while margin trading. Anywhere I've looked for information about margin trading on bitmex says to absolutely stay away from 100x leverage unless you're very experienced, but just as a small experiment I wanted to see what would happen if I were to try a trade with 100x leverage before I actually go and try to trade, but since I'm pretty inexperienced, I'm not sure I'm quite understanding everything and I'm afraid I've horribly misunderstood something fundamental here, so I'm hoping that someone more experienced here can help me out with some questions and correct me if I'm wrong on anything.
I've noticed that the price of BTC has been hovering a little lower than 11k, and sometimes going above 11k then back down over the past few days. Using this knowledge, I decided to start my test when BTC was worth ~10860 USD. I used the calculator on bitmex and set it up like so:
Quantity: 10000
Entry Price: 10880.0
Exit Price: 11000.0
Leverage: 100
And I got the following as a result:
Margin: 0.0105 XBT
Entry Value: -0.9191 XBT
Exit Value: -0.9091 XBT
Profit/Loss: 0.0100 XBT
Profit/Loss %: 1.09%
ROE %: 108.80%
From what I understand, this means that I would pay 0.0105 BTC and then if I exited at the exit price, I would have gained my initial investment of 0.0105 BTC back, as well as an additional 0.01 BTC. Is this correct or am I reading this wrong or something?am i living a lie?
Also, what I've heard is that a large part of the risk of high leverage trades comes from the liquidation price being close to the entry price, so I used the liquidation price calculator to see where that would be at, and it yielded a price of:
Liquidation Price: 10828.5
So since my entry price of 10880 was a pretty low dip from 11k at the time, and it looked like the value of BTC was rising again, I decided that it'd be risky but not unreasonable, to assume that it wouldn't dip to the liquidation price of 10828.5. So now I put my hypothetical 0.0105 BTC in and waited...
A little while later the price hit 11k without ever dipping to the liquidation price. Great! So this means I would've profited 0.01 BTC, right?jesusplease let me know if im wrong please <3
Also, I'm slightly confused about how I would go about executing this. From what I know, I would place a buy order with the quantity as what I put in the calculator, a limit price as what I put my "entry price" as in the calculator, and a leverage of 100x. Then, I would also put a sell order for what I put my limit price as in the calculator so that it would sell when it reached that price? This whole part I just said feels wrong, so please correct me. Also, I heard that people put a sell order just above their liquidation price so that they can still salvage something if it's about to be liquidated. Is this a good idea, and also the proper use case for that strategy?
I really feel like I have 90% of this stuff wrong, so if I'm wrong about anything, please explain!

How can I use Python to fetch Bitcoin / EUR price form Kraken API ?

My knowledge of programming is practically 0. I have completed 13+ hour course in codecademy and now realizing, it's not enough even for the simplest stuff I deem barely useful for me.
So, Twitter API is out (see: https://redd.it/4i644m) but Bitcoin looks interesting and why not use Kraken to get the latest BTC:EUR price (last trade closed array) and do something with it. Perhaps compared it to another pair in different currency and use FX exchange rate to calculate the difference. Simple enough? Sure, but...
Problem is, I cant figure out how to use this API and I need your help. EDIT: This part of the problem resolved. Please see 3)...
1) As I understand, to work with json and URL's i must import:
import json # import urllib.request, urllib.parse, urllib.error <-- no need for this stuff at the moment import requests #this is better 
2) I need to fetch public ticker info for XBT/EUR pair and this is where I get stuck
https://www.kraken.com/help/api#get-ticker-info
Any help pointing me to a right direction is welcome. Remember, I understand practically nothing about Python or any other programming language.

How do trades / positions work?

Let's say you have made a 100€ deposit on Kraken. The balance is in EUR. You want to buy bitcoin.
Screenshot here.
Is it:
  1. You buy 0.01 XBT. The balance of the account is now:
    XBT 0.01 EUR 38.54 
    The trade is closed. No further action is required. These balances will stay unchanged until a new trade is done.
  2. You buy 0.01 XBT. You have an "open position" (long in XBT) of 0.01 XBT. It is waiting to be closed one day, and then the P&L (profit & loss) is calculated. Similar to this screenshot. At the end of the open/close position (let's say the XBT has increased a little between the open and the close), the new balance is calculated with the P&L:
    EUR 103.13 
Is Kraken doing 1. or 2.?
As far as I know Forex (non-crypto) trading platforms use the system 2. For example if you have an EUR deposit / balance and you're trading EUUSD, you can never withdraw in USD. You just open/close positions, and then the P&L is applied on the EUR balance.
It's not clear for me if Kraken offers 1. or 2.

  4. The Italian authorities seized bitcoin from BitGrail wallet following a court order by Tribunal of Florence, however didn’t mention the entire worth of funds seized. The seizure follows a petition that was filed with the court’s by victims of the BitGrail hack.
  5. Binance has completed the distribution of EON. You can login and check that the EON has been credited to your account. The distribution of EON was calculated at a rate of 1 EOS:1 EON and was based on a snapshot of EOS balances at 01/06/2018 4:00 AM (UTC). EON withdrawals are now open.
  6. EOS bugs: users felt an almost five-hour downtime because the blockchain paused at June 16, which immediately triggered a knee-jerk response from all active EOS Block Producers. The block producers along with ‘standby nodes’ quickly jumped into a conference and after almost an hour of discussion, decided that it would be best for all standby nodes to temporarily disable their nodes. Currently the Mainnet is live again. But it is not very good start for the project. As for now, therewere only problems with mainneet.
  7. MoneyGram has partnered with GCash to launch instant remittances into Philippines.

Math behind hedging Ethereum

I have some Ethereum I want to hedge. Selling is not an option at the moment and there's still basis to grab, right? :) On a sidenote, I want to hedge towards the dollar.
Prices at the moment:
ETHH18: 0.1066 XBTH18: 10,700.00
 
So for the sake of simplicity lets say I have 10 ETH, which at the moment are 1.066 BTC
I short 10 ETHH18, lock in a price of 0.1066 vs. BTC
But since my P/L is in BTC and I want to keep it neutral towards the dollar, I need to short (1.066 x 10700) = 11,406 contracts of XBTH18, correct?
My margin would be:
1.066/50 = 0,02132 BTC for the ETH - futures 1% of 1,066 = 0,01066 BTC for the XBT - futures.
 
I'm trying to calculate the overall margin requirement for a hedging account like this. The risk obviously is Bitcoin and Ethereum prices rising at the same time so I get squeezed out of my hedge. BTC up/ETH down and vice versa would be manageable by jugling margin between positions. Can anybody make a suggestoin on how to attack this case in a practical manner?
I don't want to tie up too much margin on the one hand, on the other I don't want to check the portfolio everyday to decide weither I need to post more margin.
 
thanks for your input

Technical Analysis Weekly Review: 5. Momentum & Volatility

Technical Analysis Weekly Review by ClydeMachine

Previous Week's Post:
4. Moving Averages & MACD
This Week:
5. Momentum & Volatility
Next Week's Post:
6. A Trading Plan, Part 1

5. Momentum & Volatility TL;DR


5. Momentum & Volatility

Let's tackle two topics this week! It's go-time!

Momentum = Acceleration or Deceleration

Momentum is the rate of change in a price over time. For our uses, we compare the current price to past prices and can calculate its rate of change thereafter. This gives us another perspective of how the security is moving rather than just the raw price movement data.
This view shows "Mom (10, close)" as our Momentum indicator, using 10-interval data based on the closing price of each interval.
Notice how the price activity and the momentum line appear very close. This is because in such events as big uptrends, like seen 07:30 and 09:00, often have increasing price, as well as an increasing rate of change. Meaning, not only is it rising fast, but it's rising faster as it goes. Similarly, the fall-off that follows starts off a fast decrease, but the rate of change decreases and the price settles around $819USD, with very low relative momentum.
Momentum lines will not necessarily follow a price line! They track changes in the price, not the price itself. If a price is rising at a consistent rate, the momentum line may show no change - because the rate of change is staying constant. Watch for this mistake in your own trading plan.
If the momentum line is flatlined, that means the price is no accelerating nor decelerating - this can still occur when the price is changing, so long as it is changing the same amount every interval!
Momentum can be used as a trend reversal signal, ahead of the actual price change. To use this as a leading indicator, watch for the momentum to peak, followed by a divergence in momentum and price (I.e. the price rises as the momentum peaks and falls). This can signal a change in price trend, and can help a trader exit a position.

RSI: the Relative Strength Index

So the momentum is changing right now - if it's a leading indicator that's used to predict price trend changes, shouldn't we sell right when a rising price trend has a change of momentum direction? Not necessarily. This is where we need more information: just how fast is the change occurring? Is this a strong trend change, or a weak one that could be bucked in the next few bars?
Enter the RSI. This indicator tells us the relative speed of the change in price. It uses averages over time, and is calculated as follows:
 100 RSI = 100 - -------- 1 + RS RS = Average Gain / Average Loss 
A more in-depth explanation of its calculation can be found here on StockCharts.com.
The RSI is represented as a value between 0 and 100, and typically falls between 30 and 70. Crossing above the 70 mark indicates the security is "overbought," meaning that the price change has occurred so quickly and changed so much that it is a prime opportunity for traders to take their profit - everyone already bought their share of the pie, and will be looking to sell while the getting is good.
The RSI, spending most of its time between 30 and 70.
Similarly, a drop below 30 means the security has changed in price so fast and so far in the downward direction that most traders have already sold their shares, and the coin is now considered cheap -an opportunity for bulls to buy back in.
A major issue to be aware of with the RSI is that a security can spend a long time in overbought or oversold territory when a strong price trend is occurring. This is a key time to watch for a divergence between price movement and the RSI line, as this could be a warning of an upcoming trend change.

Volatility = Variation in Price

When we look at the volatility of a security's price, we're really looking at the changes in the expect future price range. This is to help us better plan our targets to maximize profits and minimize losses. This measure is really looking to give you an indication of the level of risk you are facing. High volatility means higher profit potential and higher loss potential, while low volatility means less potential profitability and less potential loss.
A quick note about Bitcoin volatility: lower volatility encourages merchant adoption, as fewer significant changes in currency valuation generally means it's easier to tag items at certain prices denominated in XBTs. When the valuation fluctuates a lot in periods of high volatility, it's hard to know how much a single Bitcoin will buy. For that reason, vendors are forced to value their items in a traditional, more consistently valued currency, and adjust the actual Bitcoin denominated price according to how much of the traditional currency they expect to get. Example: A vendor wants to sell an item for Bitcoin, but is unsure if today's value of 0.058 XBT will have that same buying power a month from now - so she pegs the price at $50USD and will adjust the XBT price display as the value changes. Generally speaking, high volatility is opportune for aggressive traders, and low volatility is opportune for vendors and Bitcoin believers. There's the silver lining in both situations.
Also worth noting: Generally speaking, higher volatility and trader anticipation over a new price move are linked. Excited traders make for more excited price activity - it's a real thing!
How can we use volatility to our advantage in our trading plan? By creating channels that predict a future price range, of course! We can measure volatility using standard deviation. This is a "measure of the dispersion of prices away from the average," in Barbara Rockefeller's words. The raw standard deviation isn't a terribly useful indicator on its own, and you likely won't find it in trading software - because others have built on it to make more reliable indicators, one of the most widely used being Bollinger Bands.
So let's make a roadmap.

What Is Bitcoin? Introduction To Digital Cash

Just like a dollar or a Euro can be spent to buy goods or services, Bitcoin can be used to buy – well, almost anything, from a pizza to a Lamborghini.
But instead of holding a piece of paper or a coin when you go to checkout, you hold exclusive access to an encrypted digital asset (called a “private key.”) This allows you to access your bitcoins and transfer them to someone else.
Thousands of merchants around the world accept bitcoins as payment including Overstock.com, Expedia, and Rakuten.
Some argue that Bitcoin is also (or alternatively) a “store of value” similar to gold.
In other words, like gold, it doesn’t have a lot of intrinsic value or use (gold has some manufacturing uses, but most of it is stored by central banks or given ‘value’ by jewelers). We know from looking at the markets that an ounce of gold is worth some number of dollars on any given day. Bitcoin is similar – the people who hold bitcoins, or want to trade them, mutually agree on what they are worth today.
Traders love the volatility of Bitcoin, which is at times extreme. For example, between October 2017 and January 2018, the value nearly quadrupled from $5,000 to $20,000, but then gradually settled back down to $6,000 and (today, at least) around $11,000. It is with no irony that we say Bitcoin (XBT or BTC) is still very much in price discovery phase, and there are some who believe it could be worth hundreds of thousands or even millions eventually.
To keep to the analogy of gold, Bitcoin is also limited in its total supply. Altogether, the total number of bitcoins that will ever exist is just under 21 million. Again, like gold, there is a method for ‘mining’ new bitcoins which rewards the people who put their time, energy, and cash into complex computer calculations to create new ones. Right now, about 16.9 million bitcoins have been created.
Bitcoin can be traded for fiat cash on digital exchanges like Coinbase, Robinhood, and dozens of others. Most exchanges also offer other digital currencies or ‘tokens’ which you can exchange for Bitcoin, and which may have some real-world utility beyond being a means of payment or a store

Petite analyse détaillée des principales cryptomonnaies

Bonjour,
voici un résumé avec mon avis sur quelques cryptomonnaies intéressantes du top 50, avec mon avis sur chacune d'entre elle. Certaines ont des sources (en français) qui vous permettront de creuser un peu. N'hésitez pas à donner votre avis pour améliorecompléter ce tour d'horizon :)
Bitcoin (XBT) : or numérique Montant maximum : 21 millions de bitcoins (actuellement : autour de 16,5 millions). C'est la cryptomonnaie la plus ancienne, la plus solide et la plus répandue. Elle représente à elle seule la moitié de la capitalisation totale des cryptomonnaies, et elle sert souvent d'intermédiaire entre deux autres cryptomonnaies. Elle a 9 ans et sa conception n'a jamais été mise en défaut. C'est la cryptomonnaie actuellement la moins risquée des cryptos, au moins à moyen terme (quelques années) - ce qui ne veut pas dire qu'elle est sans risque ! Mon avis : Selon moi le bitcoin a un vrai avenir sur tout ce qui est transactions entre personne genre virements bancaires ou éventuellement paiements de grande valeur, mais pas vraiment pour les achats du quotidien : dans l'état actuel de la technologie, le bitcoin a un problème de "scabilité" (possibilité de faire de très nombreuses transactions par seconde). Plusieurs innovations sont attendues en 2018 pour améliorer ce point, notamment le Lightning Network qui permettrait de décharger une partie des transactions. Côté investissement, n'importe quel portefeuille que vous vous ferez devrait contenir des bitcoins. La proportion dépend du risque que vous souhaitez prendre mais 1/3 à 2/3 de votre portefeuille semble une fourchette raisonnable.
Ethereum (ETH) : plate-forme de smart contracts Montant maximum : pas de maximum (actuellement : presque 100 millions) Cette cryptomonnaie a été créé en 2015, avec à sa tête Vitalik Butlerin, un développeur reconnu dans la communauté. L'ethereum a un intérêt fondamental par rapport au bitcoin et autres cryptos similaires : il permet d'exécuter des "smarts contracts", c'est à dire des bouts de code. Cela a un potentiel d'applications beaucoup plus large que le bitcoin, et a même lancé une nouvelle génération de cryptomonnaies. Par ailleurs, elle est soutenue par quelques grosses entreprises, regroupées au sein de l'Ethereum Alliance - même si rien ne garantie que ces entreprises vont effectivement utiliser l'ethereum et non pas leur propre cryptomonnaies à l'avenir... Mon avis : Malgré un risque supérieur à celui du bitcoin, ça me semble être une cryptomonnaie qui a un intérêt potentiel important, et donc pourrait devenir une technologie réellement disruptive. Les smarts contracts ont pour énorme avantage d'être infalsifiables ("code is law") - ce qui a d'ailleurs déjà eu de fâcheuses conséquences (cf Ethereum Classic, voir ci-dessous) et continue à en avoir (une erreur dans un smart contract de Parity durant l'été 2017 a gelé des centaines de milliers d'éther)... Malgré ce potentiel énorme, beaucoup reste à faire et à développer, et certains commencent à se plaindre du statut "Work In Progress"/"Proof of Concept" qui semble durer. Certains pensent d'ailleurs que sa valeur est trop élevée par rapport à sa valeur fondamentale : on n'utilise pas vraiment l'éther comme cryptomonnaie, mais comme support pour les smarts contracts, surtout que sa valeur est actuellement portée par l'essort des ICO (Initial Coin Offering).

Ripple (XRP) : la crypto des banques Montant maximum : environ 100 milliards (actuellement : environ 38 milliards) - il s'agit d'une crypto déflationniste (i.e., le nombre total de ripple diminue avec le temps). 6 milliards sont également détenus par les créateurs, et le reste est placé en "Escrow" Cette cryptomonnaie existe depuis quelques années déjà, avec des premiers concepts datant de 2004. Son but est de réduire des taux de changes entre n'importe quelle monnaie du monde, en passant par le Ripple comme monnaie intermédiaire. La gestion est cependant centralisée, ce qui est différent de la plupart des autres cryptomonnaies ; mais cela peut être considéré comme un avantage pour les banques traditionnelles. Ripple a noué des partenariats importants (American Express en novembre 2017, ou la fondation Bill and Melinda Gates, par exemple), qui montre un réel intérêt du monde de la finance "classique". Cette cryptomonnaie est "pseudo-décentralisée" : la validation des noeuds est confiée à un certain nombre d'acteur sélectionnés à l'avance. Mon avis : C'est une idée intéressante, et son positionnement particulier par rapport aux autres cryptomonnaies (ne servir que d'intermédiaire) en fera peut-être son succès. Le principe des taux de change n'est pas spécifique au ripple mais c'est un bon angle marketing. Quelques zones d'ombre déplaisent cependant à la communauté crypto, notamment l'aspect pseudo-décentralisé qui va à l'encontre de la philosophie générale des cryptomonnaies, et le grand nombre de ripple détenu par l'équipe de développement, donc on ne sait pas comment ils vont être utilisés. Pour creuser : Vidéo de Blocs sur Ripple .
Ethereum Classic (ETC) : clone d'ethereum voué à l'échec Montant maximum : pas de maximum (actuellement : presque 100 millions) En 2016, une faille a été découverte par des hackers dans un smart contract (un DAO) basé sur Ethereum (donc non lié au code Ethereum lui-même). Cela a permis un vol historique de plusieurs millions de dollars. L'équipe de développement et l'écrasante majorité des utilisateurs ont accepté de réécrire la blockchain pour annuler le vol. Cela a nécessité un hard fork, qui est devenu le nouvel Ethereum. Une petite partie de la communauté a cependant considéré que l’intervention humaine pour décider où l’argent était n’était pas “éthique”, même si cela impliquait une perte d’argent par des investisseurs n’ayant pas suffisamment fait attention à ce qu’ils faisaient de leurs tokens, et qu’il fallait donc garder une blockchain “non manipulée”, c’est devenu l’Ethereum Classic (ETC). Tous les possesseurs d'ETH ont donc eu la même quantité d'ETC. Mon avis : Personnellement, je refuse de soutenir cette cryptomonnaie pour des raisons philosophiques. C'est un pur produit de spéculation, et je n'y vois peu d'avenir concret. Pour creuser, un message d'un ancien participant au projet ETC, qui montre un peu les dessous de cette cryptomonnaie et pourquoi il faut sérieusement s'en méfier
Bitcoin Cash (BCH) : clone du bitcoin hostile au bitcoin Montant maximum : 21 millions de bitcoins (actuellement : autour de 16,5 millions). Comme pour l'ETC avec l'Ethereum, il s'agit d'une copie du bitcoin suite à un hard fork. Le problème de base est la scabilité, c'est à dire le nombre de transactions que l'on peut faire passer à la seconde. Le bitcoin est très encombré actuellement, ce qui augmente les frais de transaction de manière vertigineuse (il faut payer cher pour être sûr que sa transaction va être effectuée). Pour régler ce problème, plusieurs solutions existe. Le Lightning Network, proposée par les développeurs "historiques" du bitcoin n'est pas encore prêt. Des mineurs ont décidé de lancer leur propre blockchain, avec une taille de bloc de transaction 8 fois plus grande qu'actuellement, et une difficulté de minage mise à jour plus rapidement. Mon avis : Le Bitcoin Cash a été lancée face au bitcoin de manière "hostile", avec pour intention claire de remplacer celui-ci. La solution retenue (augmenter la taille des blocs de transaction) n'est que temporaire et ne règlera pas le problème, qui nécessite une vraie rupture technologique. Il y a eu beaucoup d'hostilité, de désinformation et de délit d'initié de la part de cette cryptomonnaie. Comme pour l'ETC, je refuse de soutenir cette cryptomonnaie pour des raisons philosophiques. Pour creuser : Vidéo de Blocs sur Bitcoin Cash .
Litecoin (LTC) : clone du bitcoin en un peu plus rapide Montant maximum : 84 millions (actuellement : environ 49 millions) Il s'agit d'une cryptomonnaie similaire au bitcoin, avec quelques petits avantages, genre un minage plus facile et un temps de validation des transactions plus court. L'équipe de développement, dont Charlie Lee est la figure la plus connue, a l'air solide, et arrive à implémenter des nouveautés (avec succès) plus facilement que le bitcoin. Mon avis : Il y a peu de chances que cette cryptomonnaie supplante le bitcoin, étant donné que malgré ses avantages, elle n'a pas réussi à supplanter le bitcoin depuis son lancement il y a 5 ans. Cependant vous ne prendrez pas beaucoup de risque non plus en investissant dans cette crypto.. Pour creuser : Vidéo de Renan sur Litecoin .
Cardano (ADA) : nouveau concurrent de Bitcoin Montant maximum : 45 milliards d'ADA. Lancée le 1er octobre 2017, cette crypto a fait une entrée remarquée dans le top 10 des cryptos en 2 mois à peine. Il se démarque de ses concurrents par le fait d'être développés par des universitaires. Il s'agit d'une plateforme de smart contracts. La validation se fait par proof-of-stake, c'est à dire dépendamment du nombre d'ADA possédés, et non pas par proof-of-work comme le bitcoin. Le modèle de gouvernance se fait par un certain nombre d'élus qui décident de l'évolution de la crypto. Mon avis : la crypto semble avoir des bases solides, et le modèle de gouvernance est intéressant, plus souple que bitcoin sans être centralisé de manière quasi immuable par de gros acteurs comme ripple. On peut le voir comme un futur challenger de Bitcoin.
Monero/Dash/Zcash (XMDASH/Zcash) : cryptos anonymes Ces cryptomonnaies ont en commun d'avoir un principe similaire au bitcoin, mais avec un accent donné sur l'anonymat. Cela peut être intéressant pour plusieurs types de publics, et donc peuvent devenir une alternative viable. Pour information, le Monero et le Dash, avec le bitcoin et l'ethereum, étaient acceptés sur AlphaBay (le principal site web de ventes illégales, dont la drogue, sur le web avant sa fermeture). Les équipes de développement ont l'air solides pour les trois. Mon avis : Ces cryptomonnaies ont un réel intérêt par rapport au bitcoin. J'aurais cependant du mal à dire laquelle est la plus intéressante entre les trois. Le Dash a une meilleure communication, Monero est plus "artisanal" mais plus solide techniquement, Zcash a un potentiel de développement plus élevé. Pour creuser: Vidéo de Blocs sur Monero . Pour creuser: Vidéo d'ArtPlay sur Dash .
NEM (XEM) : crypto asiatique Montant maximum : 9 millions (actuellement : 9 millions) C'est une cryptomonnaie visant essentiellement un public asiatique. C'est une cryptomonnaie soutenue par de grosses banques et institutions japonaises, ce qui peut contribuer à son succès. Sa valeur a explosé en quelques mois. Mon avis : Cette crypto a du succès, mais comme on en entend moins parler dans le monde occidental, il est plus difficile de se faire un avis objectif.
IOTA (MIOTA) : crypto pas encore fonctionnelle destinée à l'internet des objets C'est une cryptomonnaie visant à faire des micropaiements dans le monde de l'internet des objets. Cela représente une technologie réellement "disruptive". Un point intéressant de cette crypto est la scabilité (c'est à dire la possibilité de développement à grande échelle), assurée par construction même : pour chaque transaction effectuée avec le IOTA, il faut valider 2 transactions au préalable. Mon avis : L'internet des objets a un grand avenir, et cette idée semble séduisante. Lors de son lancement, sa capitalisation a directement dépassé le milliard de dollars. La technologie n'est cependant pas encore au point, et la validation de transactions comme préalable à chaque nouvelle transactions est certes un mécanisme intéressant, mais qui n'a jamais été testé. Il faut voir si c'est une technologie sérieuse et sécuritaire.
Stratis (STRAT) : créez votre propre blockchain Il s'agit d'une start-up proposant à des entreprises d'implémenter la technologie blockchain pour elles. Elle permettra de faire de la programmation en C#, un langage de programmation répandu. C'est un marché porteur, la technologie blockchain ayant un avenir certain, et Stratis est l'une des premières entreprises positionnées sur ce marché. Mon avis: Le potentiel de croissance futur dépend de la qualité de cette entreprise. Pour l'instant elle s'en sort plutôt bien Pour creuser: Vidéo de Blocs sur Stratis .
EOS (EOS) : smart contracts gratuits EOS sert de plateformes à smart contracts, un peu comme Ethereum. Mais à l'invers de celui-ci, EOS garantit des transactions gratuites, et les promoteurs promettent de pouvoir gérer des millions de transactions par seconde. Cette crypto a un lancement particulier et pour l'instant unique : au lieu de mettre en vente tous les tokens d'un coup comme c'est généralement le cas, ils en mettent un 1/365e chaque jour pendant 1 an (après une vente initiale). Mon avis: Le pari est risqué mais valable. Le format particulier de son ICO fait qu'on a le temps de voir comment le projet évolue et si l'équipe est solide - ce qui est un gage de confiance.
NEO/Waves/Omni/Nxt/Bitshares/Counterparty (ANS/WAVES/OMNI/NXT/BTS/XCP) : smart contracts alternatifs Ces cryptomonnaies ont un concept similaire à Ethereum, c'est à dire d'être une plateforme pour des smart contracts. Mais elles ont moins de succès: parmi les 50 assets les plus populaires, 43 sont basées sur Ethereum, 4 sont basés sur Omni, 1 sur Nxt, 1 sur Waves, 1 sur NEO... Mon avis : pour l'instant ces cryptomonnaies ont moins de succès que Ethereum, mais ça pourrait changer avec NEO ou Waves qui ont eu beaucoup de succès récemment. Omni et Nxt ont à peu près le même âge que Ethereum donc je doute de leur succès. Je ne connais pas bien les deux derniers. Pour creuser : Vidéo de Blocs sur NEO .
Iconomi (ICN) : jouez à la bourse dans le monde des cryptos Cette cryptomonnaie vise à créer des outils de trading comme en bourse : portefeuille de valeurs, indices, etc. L'idée est d'acheter des tokens de cette cryptomonnaie, sachant que l'argent sera investi sur d'autres cryptomonnaies et suivra leur valeur. L'équipe de développement a l'air sérieuse et a sorti mi-2017 le premier volet de son projet (le ICNX) Mon avis : C'est une bonne idée si vous ne voulez ou pouvez pas passer trop de temps à suivre le détail du marché - activité hautement chronophage...
Golem (GNT) : louez votre puissance de calcul Cette cryptomonnaie représente des tokens pour louer de la puissance de calcul. Le principe est que si l'on a besoin de beaucoup de puissance de calcul pour un projet particulier (calcul en laboratoire, rendu 3D dans un film d'animation, etc), on passe un contrat sur la blockchain pour effectuer ces calculs, distribué entre de nombreuses machines, sans passer par des machines hyper puissantes (comme le projet [email protected], pour ceux qui connaissent). Notez que la rémunération de ceux qui ont participé au calcul se base sur un système de loterie pour diminuer les coûts de transaction. Mon avis : L'idée est séduisante, et c'est probablement l'un des projets les plus solides, car on peut avoir une idée de sa valeur fondamentale, en comparant aux services existants de cloud computing (Amazon ou Microsoft). Mais c'est paradoxalement l'un de ses défauts : sa valeur ne grimpera probablement pas à des sommets car sa valeur fondamentale pouvant être grossièrement estimée, sa valeur d'échange ne devrait pas trop s'en éloigner. Par ailleurs, le revenu tiré de la puissance de calcul par Golem sera toujours comparé au revenu potentiel du minage, et sera probablement comparable.
AuguGnosis (REP/GNO) : pariez sur l'avenir Ces deux projets, relativement similaires, proposent de faire des paris sur l'avenir grâce à des smarts contracts, un peu comme chez les brokers à Londres. Ils se basent sur la fameuse "sagesse des foules" : si on demande à un grand nombre de gens de faire une estimation (par exemple, le nombre de boules dans une boite), alors la valeur moyenne sera souvent très proche de la vraie valeur. Il y a un certain nombre d'hypothèses pour que cela fonctionne, notamment que les gens font des estimations indépendantes (ils ne discutent pas entre eux, sinon ils s'influencent) et non biaisées, ce qui est en pratique difficile. Mon avis : Ce sont des projets intéressants, qui peuvent faire connaitre le monde de la blockchain au grand public - tout comme on donne parfois les estimations des brokers anglais pour le résultat d'une élection ou un match de foot. Je n'ai pas trouvé leurs plateformes de pari vraiment claires, mais j'imagine que ça va s'améliorer avec le temps.
Dogecoin (DOGE) : clone rigolo du bitcoin Montant maximum : pas de maximum (actuellement : presque 110 milliards) Un clone du bitcoin dont les possesseurs cherchent surtout à faire augmenter sans limite sa valeur (leur slogan : "to the moon!"). Mon avis : une cryptomonnaie qui n'a pas beaucoup d'intérêt à part pour son symbole marrant (une tête de chien). Sérieusement.
GameCredits/MobileGo/FirstBlood (GAME, MGO, FIRST) : les cryptos des jeux vidéos Ces cryptomonnaies se concentrent dans le monde du jeu vidéo, selon trois marchés : la vente dématérialisée "à la Steam" (plutôt pour GameCredits), les micropaiements dans le jeux mobiles (plutôt pour MobileGo) et les paris sur les tournois de jeux vidéos (plutôt pour FirstBlood). Chacun de ces marchés a un grand potentiel ; la grande question est de savoir si ces acteurs vont réussir à s'imposer. Cela dépend plus de la qualité des entreprises que de la cryptomonnaie en elle-même. Mon avis : Ces cryptomonnaies sont dignes d'être suivies, vu le potentiel du marché. Mais je pense personnellement que ces cryptomonnaies doivent venir des acteurs historiques du marché (Steam, Electronic Arts, Blizzard...), déjà bien implantés avec des plateformes solides, plutôt que d'extérieurs qui doivent s'imposer. La tendance actuelle est de se rapprocher du e-sport, encore sous-développé.
CIVIC (CVC) : identifiez-vous et authentifiez-vous grâce à la blockchain Cette cryptomonnaie s'intéresse aux concepts d'identité. Ils proposent de faire des vérifications d'identité avec une validation sur la blockchain : par exemple, un site web, au lieu de demander une pièce d'identité et une preuve de domicile, pourrait simplement demander une confirmation dans la blockchain CIVIC que son client est bien celui qu'il croit être. Cette demande serait monnayée avec le token CIVIC. Leur ICO a été très particulière : le nombre de tokens mis en circulation était limité et avait un mécanisme pour avoir un maximum d'utilisateurs plutôt que pour lever le maximum d'argent possible - ce qui est très cohérent avec le projet. Mon avis : un super projet, et l'équipe semble bien tenir la route. Certains s'inquiètent du côté "Big Brother" de cette technologie - toutes les infos personnelles sont stockés sur un registre - mais le projet est en tout cas tout à fait cohérent avec le potentiel de la technologie blockchain.
InsureX (IXT) : assurez-vous grâce à la blockchain Il s'agit d'un smart contract avec assurance - c'est à dire que l'on s'assure pour un risque (par exemple : le bitcoin descend en-dessous de 20000 euros avant le 1er septembre). Le "smart contract" permet de s'assurer que le contrat sera exécuté quoi qu'il arrive. Mon avis : l'idée est bonne, c'est même la base des smart contracts, mais cela arrive selon moi trop tôt : le monde des cryptomonnaies est encore jeune et peu mature, et je vois mal une adoption même partielle d'assurances sur une blockchain. Mais le projet est à suivre quand même.
TenX, TokenCard, Monaco, WireX/Xapo (PAY,TKN, MCO, ???) : cartes bancaires cryptos Ces projets visent à pouvoir dépenser ses cryptomonnaies avec une carte bancaire. L'idée est bonne, car ça permet d'être peu affecté par les taux de change variables entre pays - par contre, on est très affecté par la volatilité des cours des cryptomonnaies. Plusieurs entreprises se sont lancées sur cette idée, il reste à voir laquelle s'en sortira le mieux, et si cela a réellement un intérêt pour les paiements du quotidien. Mon avis : C'est une idée qui permet d'utiliser réellement ses cryptos, plutôt que de les utiliser uniquement à des fins de spéculation. Cependant, ce marché est encore jeune : par exemple, début janvier, la plupart des cartes bancaires ont été désactivées, car elles passaient par un intermédiaire du nom de WaveCrest qui a vu ses activités stoppées par VISA.
Basic Attention Token (BAT) : alternative payante à la publicité sur internet Ces tokens vont de pair avec un navigateur, Brave. Ce navigateur a du succès actuellement, notamment grâce à sa capacité native de bloquer les publicités (comme adBlock ou uOrigin), ce qui en plus accélérerait le chargement des pages web. Le modèle derrière propose d'accepter certaines publicités, d'être rémunéré pour le visionnage via un pourcentage sur le coût de la publicité, et ce sous forme de tokens BAT. Le lancement du BAT a été un énorme succès, avec 35 millions de $ en tokens vendus en 30 secondes. Mon avis : une belle idée. Cela repose sur plusieurs inconnues cependant : l'adoption massive du navigateur Brave (malgré son succès croissant, sa part de marché reste faible) ; arriver à mettre le mécanisme de partage de rémunération avec les utilisateurs ; être sûr que le montant des rémunérations soit suffisantes, etc. Si toutes ces conditions sont remplies, l'intérêt est fort. Personnellement, je préfère attendre un peu pour voir l'évolution.
Tether (USDT) : vaut 1 US$ ou moins Cette cryptomonnaie a été crée comme valeur refuge : 1 USDT est censé valoir 1 US$. Tant que la conversion USDT/US$ est possible, cela revient au même d'avoir l'un ou l'autre. Cependant, comme cette conversion n'est pas toujours possible, les gens préfèrent avoir des US$, que l'on peut utiliser partout : ainsi, la valeur d'1 USDT est en pratique légèrement inférieure à celle d'1 US$. Mon avis : Le concept permet de retirer des fonds en USD - en attendant de les réinvestir - sans devoir payer les taxes sur les gains financiers. Selon moi c'est plutôt pour les citoyens américains qui sont taxés assez strictement pour les gains financiers. Par ailleurs, l'entreprise derrière les USDT injecte régulièrement des nouveaux tokens, et de nombreuses rumeurs doutent de la capacité de l'entreprise à avoir des stocks suffisants pouvoir échanger un nombre appréciable USDT contre des USD si les possesseurs le demandaient. Méfiance !
Bitconnect Coin (BCC) : Arnaque à la Madoff Montant maximum : 28 millions de bitconnect coins (actuellement : autour de 6,5 millions). Cette crypto a beaucoup de similarités avec le bitcoin, sa principale particularité est de proposer des échanges d'utilisateur à utilisateur, sans passer par une plateforme d'échange. Par ailleurs, elle utilise une combinaison de Proof-Of-Stake (POS) et Proof-Of-Work (POW). En clair, pour valider une transaction, au lieu de se baser sur la puissance de calcul du validateur (POW), on se base sur la quantité de cryptomonnaie qu'il possède (POS). Sur le principe, cela pourrait sauver beaucoup de puissance de calcul ; mais la vulnérabilité de cette technique est moins assurée. Ils proposent aussi un intérêt très élevé si vous épargnez vos BCC (jusqu'à 1%/jour, soit 90% par an !). Mon avis : attention, malgré cette présentation, selon la grosse majorité des personnes - moi inclus -, il s'agit d'une escroquerie. Les indices sont en effet nombreux : aucune présentation des membres de l'équipe sur le site officiel ou l'annonce de lancement sur bitcointalk ; un taux d'intérêt délirant ; un système spéculatif douteux : les utilisateurs achètent des BCC directement aux développeurs, et comme les intérêts sont très élevés, ils les vendent rarement. Donc les développeurs sont les principaux bénéficiaires (ils attendent probablement que le cours soit au plus haut pour disparaitre dans la nature). Si vous mettez le moindre satoshi là-dedans, faut s'attendre à le voir disparaitre à n'importe quel moment. Vous voilà prévenu. Pour creuser: Vidéo d'Hasheur sur Bitconnect .
Komodo (KMD) : plateforme décentralisée d'ICO, basée sur Bitcoin Montant maximum : ? (actuellement : autour de 100 millions). Komodo est une cryptomonnaie assez difficile à résumer, le projet est plutôt gros. Komodo est à la fois une monnaie, une plateforme et un système de smart contracts. Parmi ses caractéristiques les plus intéressantes de Komodo, c'est le lancement futur d'une plateforme d'ICO un peu similaire à Ethereum, "Monaize". Celle-ci sera notamment décentralisée et anonyme. Par ailleurs, le Komodo ne vise pas à remplacer le Bitcoin, mais au contraire se base sur celui-ci : au lieu de sécuriser sa blockchain de manière indépendante grâce à ses propres mineurs, Komodo va faire valider sa blockchain par Bitcoin. Il y a aussi un système d'"atomic swap", une fonctionnalité qui permet de faire l'échange de 2 cryptos instantanément et sans frais. Enfin, Komodo fait partie d'un écosystème de cryptomonnaie en développement, SuperNet. Mon avis : Le projet est intéressant, ambitieux et réaliste. J'apprécie le fait qu'il se base sur Bitcoin plutôt que d'essayer de remplacer celui-ci : Bitcoin ne disparaitra pas à court ou moyen terme, sa blockchain est solide, donc cela me parait judicieux de "profiter" de ses avantages. Une nouvelle plateforme d'ICO est aussi appréciable, même si le secteur est "concurrentiel". Ceci dit, le marketing n'est pas terrible - mais cela peut signifier de bonnes opportunités d'investissement à l'heure actuelle, le temps que ça se développe. On en est encore au début, il faut voir comment ça évolue ! Pour creuser: Vidéo d'ArtPlay sur Komodo .
Siacoin, Storj, MaidSafeCoin (SIA, STORJ, MAID) : louez votre espace disque L'idée de ces cryptomonnaies est de faire du cloud-storage grâce à la blockchain. En gros, si vous avez besoin d'espace de stockage, vous pouvez mettre vos données sur le cloud, qui seront redistribuées parmi les participants, avec une rémunération par cryptomonnaie. Cela ressemble à Google Drive ou Dropbox, sans l'aspect centralisé. L'un des enjeux est la confidentialité des donnes. Mon avis : un concept intéressant, même si ça m'enthousiasme moins que les projets de cloud-computing basés sur la blockchain. Cela peut marcher si on a plus confiance dans la confidentialité du cloud-computing par blockchain que celui proposé par des entreprises dédiées. Parmi les différents projets, le Siacoin a l'air d'être le plus solide, avec des mises à jour régulières et une roadmap respectée.
Electroneum (ETN) : utilisez votre smartphone pour miner Cette cryptomonnaie a lancé une ICO avec beaucoup de succès en octobre 2017 (dans les 40 millions de dollars). Le principe, c'est de proposer de faire du mining avec son téléphone. Les téléphones sont évidemment beaucoup moins puissants que les ordinateurs, mais le but est de proposer une application simple, que n'importe qui peut télécharger. Ainsi, cela pourrait convaincre des gens de rentrer dans l'écosystème des cryptomonnaies grâce à une friction très faible. Cette cryptomonnaie pourrait ensuite servir à des jeux mobiles, des paiements comme chez Uber, etc. Mon avis: le point fort des développeurs, c'est la communication, ils la font bien. Mais cette cryptomonnaie repose sur deux (gros) risques : va-t-on réussir à attirer de nouveaux utilisateurs par ce biais ? Et : sur quelle application concrète cela va-t-il déboucher ? Par ailleurs, l'équipe ne semble pas hyper solide niveau technique. Enfin, le minage sur mobile, si l'on en croit le whitepaper, ne fera que "simuler" du vrai minage, donc les fondamentaux semblent douteux.
Steemit (STEEM) : soyez rémunérés pour vos productions populaires Cette cryptomonnaie est destinée à récompenser la production de contenus populaires sur la plateforme "Steem" (à ne pas confondre avec Steam). Cette plateforme permet de publier des contenus sous différentes formes : texte (comme un blog), vidéo (comme Youtube), messages courts (comme Twitter)... Les visiteurs peuvent ensuite approuver un contenu qu'ils apprécient, avec un poids variable selon leur réputation dans la communauté ; le producteur du contenu recevra une rémunération en Steem. Notez que les contenus textes sont stockés sur la blockchain du projet (n'écrivez pas de bêtises, elles seront gravées dans le marbre !) Mon avis : c'est une façon originale de rémunérer les producteurs de contenus de qualité - même si ça peut favoriser les contenus "populaires" plutôt que "de qualité", mais ceci dépasse le cadre des cryptomonnaies. Ce projet a un usage réel et ludique qui font son succès, mais a deux écueils importants : il est basé sur une plateforme unique, d'où des problèmes de centralisation ; et il a un fort côté inflationniste, car le nombre de tokens augmente fortement avec le temps (une multiplication par deux par année, en moyenne), et cela fait douter de la viabilité du modèle à long terme. Pour creuser: Vidéo d'Hasheur sur Steemit .
Lisk (LSK) : smart contracts codés en javascript Lisk est une plateforme pour smart contracts. Son avantage, c'est que les smart contracts sont codés dans un langage proche du javascript, c'est à dire un langage connu depuis de nombreuses années et facile d'utilisation, plutôt qu'un nouveau langage à apprendre comme pour Ethereum (Solidity). Selon les concepteurs, cela devrait faciliter la création de nouveaux smart contracts. Mon avis: Les smart contracts sont actuellement le principal point faible, niveau sécurité, dans l'écosystème. Faire un effort d'accessibilité pour écrire les smart contracts est une bonne chose, car plus les smarts contracts sont faciles à relire par le grand public, plus on peut avoir confiance (plutôt que de devoir se fier à quelques développeurs hyper spécialisés). Mais il faut aussi que les smart contracts soient correctement audités avant d'être déployés. Pour l'instant le langage n'est pas encore prêt, mais on peut s'attendre à une belle hausse au moment de la release officielle.
Einsteinium (EMC2) : la science pour les nuls Voici une crypto qui veut être la crypto "scientifique" du milieu, et a choisi un nom et un sigle rigolos et qui sonnent "scientifique" au grand public. Les concepteurs annoncent vouloir financer des projets scientifiques avec les fonds levés, et la rentabilité de ceux-ci permettra de financer les futurs projets. Mon avis: Pour avoir travaillé dans le milieu de la science, ce projet n'a aucun d'intérêt. Afin d'être rentables, les projets financés seront des projets destinés à être rentables à court terme, et pas les plus intéressants. Et ces projets qui sont censés être rentables auraient de toutes façon trouvé des fonds pour se lancer dans tous les cas, donc pourquoi passer par Einsteinium ? Probablement pour lever plus de fonds que nécessaire. Et je pense que les projets qui lèveront le plus d'argent sont ceux qui savent "vendre du rêve" - et dans le milieu scientifique, c'est est rarement gage de qualité (c'est même plutôt l'inverse...). Bref : même si la valeur de cette crypto est en augmentation, fuyez, ses fondamentaux sont mauvais. D'ailleurs, en décembre 2017, cette crypto a fait un gros pump suite à une "annonce extraordinaire" - dixit l'équipe de développement -, qui s'est révélée être un bide total (un changement de l'algorithme de minage). Certains soupçonnent l'équipe de développement d'avoir organisé cette annonce volontairement pour faire un bon coup. Bref, méfiez-vous !
Dentacoin (DCN) (et non pas DTC) : bitcoin pour les dentistes Cette crypto souhaite devenir la "cryptomonnaie des dentistes". Elle combine paiements (grâce au token Dentacoin), système de reviews des dentistes, assurance. Mon avis : Le système de review est redondant avec ce qui existe déjà, les paiements par blockchain n'ont aucun intérêt (pourquoi payer par token son dentiste ?), et si l'assurance liée pourrait avoir un intérêt aux Etats-Unis (et encore...), elle n'est pas adaptée au système européen qui ont des services d'assurance maladie et de mutuelles de santé. Bref, bien inutile. Pour creuser: une réponse détaillée à la roadmap sur cryptofr .
PutinCoin, TrumpCoin TheresaMayCoin, MACRON (PUT,TRUMP,MAY,MCRN) : crypto-rigolo La preuve que les créateurs de cryptos ont de l'humour ;)
