Currently, Bitcoin futures have very high margin requirements. The Cboe requires 40% of the notional amount for maintenance margin, the CME requires 43%. Your broker will likely require more than that. The culprit behind these high requirements is Bitcoin’s high volatility—until that calms down the exchanges will protect themselves by requiring a bunch of up-front money. If you don’t come up with the money for a margin call they want to close out your position without leaving a negative balance.
Some Centra investors have their doubts, and a plaintiffs' law firm has brought a class action complaint against Centra demanding the investors' money back. The complaint is fun -- Centra had a “Blog/Media Bounty” program to "Reward Experienced Writers who write quality Reviews, Articles About the Centra Project and the ICO crowdsale" -- but not that fun, because the plaintiffs' lawyers don't actually need to prove that Centra was a scam. Their job is much easier: All they need to do is prove that the tokens Centra sold in its initial coin offering were securities. If they were securities, they were sold illegally: They were offered publicly without being registered with the Securities and Exchange Commission, or being exempt from registration. And one remedy for the illegal sale of securities is that the buyers can demand their money back -- whether or not Centra is legitimate, whether or not it is actually using the money to build a cryptocurrency debit card, whether or not it made any misleading statements in the ICO.
The value of the bitcoin futures contracts is generally based on the expected value of bitcoin at a future point in time, specifically, the expiration date of the bitcoin futures contracts. Other factors, such as cost of mining, storing and securing bitcoin may affect the value of bitcoin futures. A change in the price of bitcoin today (sometimes referred to as the “spot” price) will not necessarily result in a corresponding movement in the price of the bitcoin futures contracts since the price of the bitcoin futures contracts is based on expectations of the price of bitcoin at a future point in time. Additionally, there is no one centralized source for pricing bitcoin and pricing from one bitcoin exchange to the next can vary widely. Therefore, the value of the bitcoin futures contracts held by the Fund should not be expected to track the price of bitcoin on the Bitcoin Exchange Market.
Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against a Fund’s net investment income. Instead, potentially subject to certain limitations, a Fund may carry net capital losses forward from any taxable year to subsequent taxable years to offset capital gains, if any, realized during such subsequent taxable years. Distributions from capital gains are generally made after applying any available capital loss carryforwards. Capital loss carryforwards are reduced to the extent they offset current-year net realized capital gains, whether the Funds retain or distribute such gains. If a Fund incurs or has incurred net capital losses in taxable years beginning after December 22, 2010 (post-2010 losses), those losses will be carried forward to one or more subsequent taxable years, and will be treated as realized on the first day of the taxable year in which it is used to reduce capital gain, without expiration; any such carryforward losses will generally retain their character as short-term or long-term and will be applied first against gains of the same character before offsetting gains of a different character (e.g., net capital losses resulting from previously realized net long-term losses will first offset any long-term capital gain, with any remaining amounts available to offset any net short-term capital gain). If a Fund incurred net capital losses in a taxable year beginning on or before December 22, 2010 (“pre-2011 losses”), the Fund is permitted to carry such losses forward for eight taxable years; in the year to which they are carried forward, such losses are treated as short-term capital losses that first offset any short-term capital gains, and then offset any long-term capital gains. A Fund must use any post-2010 losses, which will not expire, before it uses any pre-2011 losses. This increases the likelihood that pre-2011 losses will expire unused at the conclusion of the eight-year carryforward period.

XBT futures is a cash-settled contract that settles to a single, tradeable auction price. In designing XBT futures, Cboe leveraged its significant product development expertise to design an instrument that allows participants to implement trading strategies in a manner to which they are accustomed. The single price settlement process gives participants the option of using XBT futures to hedge their exposure in underlying bitcoin or gain exposure to traded bitcoin prices without holding bitcoin.
Other forms of swap agreements that the Funds may enter into include: interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels.
A key attribute of a futures market is how its contract’s prices vary by expiration date. The succession of futures prices over time is called the “term structure”. If supply is stable (no seasonality or shortages) then typically futures prices will increase with expirations further in the future. This term structure configuration is called “contango” and it accounts for the fact that carry costs (e.g., time value of money) and profit expectations increase with time. Unless there are big changes in interest rates or the way that Bitcoin exchanges work I expect the level of contango in the Bitcoin futures term structure to be small. Bitcoins don’t cost much to hodl (once you have your hardware wallet) and there’s no apparent seasonality. The chart below from VIX Central shows a typical Bitcoin term structure (click on chart to get current data):
It is expected that each Subsidiary will neither be subject to taxation on its net income in the same manner as a corporation formed in the United States nor subject to branch profits tax on the income and gain derived from its activities in the United States. A foreign corporation will generally not be subject to such taxation unless it is engaged in or is treated as engaged in a U.S. trade or business. Each Subsidiary expects to operate in a manner such that it is not so engaged or so treated.
D – An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless Standard & Poor’s believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.

In the course of managing the Fund’s investments, ProShare Advisors will need to periodically adjust the Fund’s holdings in order to maintain investment exposure approximately equivalent to the Fund’s assets. This process entails obtaining additional inverse exposure as the Fund experiences gains, and reducing inverse exposure as the Fund experiences losses. The higher the volatility of the bitcoin futures contracts in which the Fund invests, the more such rebalancing can adversely affect the Fund’s performance.
The global regulatory landscape for bitcoin and other digital assets has been inconsistent and continues to evolve. Some countries have taken an accommodating approach to the regulation of digital assets while others have banned their use. There are various accommodative approaches a country may take. Sweden and Australia treat bitcoin as a currency, while Canada and Taiwan have labeled bitcoin as a digital or virtual currency, distinct from fiat currency. Norway categorizes bitcoin as a form of virtual asset or commodity. The United Kingdom treats bitcoin as private money and determined that the value added tax will not apply to bitcoin sales, but it can be charged on the commission instead. In April 2017, legislation took effect in Japan that treats bitcoin and other digital assets as included in the definition of currency. In July 2016, the European Commission released a draft directive that proposed applying counter-terrorism and anti-money laundering regulations to virtual currencies, and, in September 2016, the European Banking authority advised the European Commission to institute new regulation specific to virtual currencies, with amendments to existing regulation as a stopgap measure. Regulatory bodies in some countries such as India and Switzerland have declined to exercise regulatory authority when afforded the opportunity.

Creation Units of all Funds may, at the discretion of the Advisor, be sold for cash (the “Cash Purchase Amount”). Creation Units are sold at their NAV plus a Transaction Fee, as described below. The Advisor may also restrict purchases of Creation Units to be on a cash-only basis at any time and without prior notice, in all cases at the Advisor’s discretion.
An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[49] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[50] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[51]
(b) diversify its holdings so that, at the end of each quarter of a Fund’s taxable year (or by the end of the 30-day period following the close of such quarter), (i) at least 50% of the fair market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities limited, in respect of any one issuer, to a value not greater than 5% of the value of the Fund’s total assets and to an amount not greater than 10% of the outstanding voting securities of such issuer, and (ii) not greater than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in (x) the securities (other than U.S. government securities and the securities of other RICs) of any one issuer or of two or more issuers that the Fund controls and that are engaged in the same, similar or related trades or businesses, or (y) the securities of one or more qualified publicly traded partnerships (as defined below); and
You could imagine the spread going the other way, though. If everyone really was clamoring to short bitcoin, and if the futures offered a more convenient way to do it than the bitcoin exchanges, then you'd expect the short sellers to pay a premium to short via futures. Instead of selling a bitcoin at $18,000 today, they'd be willing to sell a synthetic bitcoin for $17,500, paying the spread to an arbitrageur who was willing to do the actual shorting for them. But the fact that the spread is mostly positive, and that bitcoin's price has been mostly going up, suggests that the demand has mostly been for synthetic long positions, not short.
Cryptocurrencies are far more volatile than stocks and bonds, and the industry evolves rapidly. An altcoin that is popular today may not exist a month or a year from now. In other words, traders should consider the possibility of losing everything when they start trading. For this reason, you should put only a very small portion of your portfolio in this sector.
Two members of the Silk Road Task Force—a multi-agency federal task force that carried out the U.S. investigation of Silk Road—seized bitcoins for their own use in the course of the investigation.[86] DEA agent Carl Mark Force IV, who attempted to extort Silk Road founder Ross Ulbricht ("Dread Pirate Roberts"), pleaded guilty to money laundering, obstruction of justice, and extortion under color of official right, and was sentenced to 6.5 years in federal prison.[86] U.S. Secret Service agent Shaun Bridges pleaded guilty to crimes relating to his diversion of $800,000 worth of bitcoins to his personal account during the investigation, and also separately pleaded guilty to money laundering in connection with another cryptocurrency theft; he was sentenced to nearly eight years in federal prison.[87]
There's a lot of ins and outs which can get confusing in arbitrage trading. We won't go into the technicals of why futures contracts trade at a premium to spot price. You can read a full explanation here. If it's not of interest to you, all you need to know is that there's a tendency, the further out in time the futures contract expires, for the premium to spot to be higher and higher in nominal percentage terms.
