These are NOT linked to or related in any way, to the futures contracts that trade on the CME or CBOE.  Not every article I have read makes this clear.  So the bright side of this story is that the contracts listed and traded on U.S. exchanges were not involved.  That is encouraging from both a regulatory aspect and for the future potential growth of cryptocurrency linked products in the U.S.
  •   Swap Agreements are agreements entered into primarily with major global financial institutions for a specified period ranging from a day to more than one year. In a standard “swap” transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined investments or instruments.
In a futures market, if the price is $500/BTC, an investor needs to buy 50 futures contracts, each worth $10. If an investor wishes to open a positive position then he goes long with “buy" contracts, and if he decides to open a negative position, he goes short with “sell” contracts. An investor’s position can be either positive or negative for the same instrument. (For more, see: Bitcoin Mass Hysteria: The Disaster that Brought Down Mt. Gox.)

The price of bitcoin has been subject to periods of high volatility. As a result, the CFE and CME have established margin requirements for bitcoin futures contracts at levels substantially higher than the margin requirements for more established futures contracts. The increased margin requirements may result in much higher upfront costs for the Funds. Market participants may be deterred from incorporating bitcoin futures contracts into their investment strategies due to these higher costs and other limitations created by the high margin requirements, such as the limit on their ability to use leverage to invest in bitcoin futures contracts. A reduction in the adoption of the bitcoin futures contracts will negatively impact the market for bitcoin futures contracts and could negatively impact the performance of the Funds. In addition, the continued volatility in the price of bitcoin may result in further increases to the margin requirements for bitcoin futures contracts by the CFE and CME, as well as some FCMs imposing margin requirements on their customers in amounts that are steeper than the margin required by the exchanges.
the Merrill Lynch Factor Model – Exchange Series benchmark). The Short ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Short”, “UltraShort” or “UltraPro Short” in their names, except for the Short Bitcoin Futures Strategy ETF) are designed to correspond to the inverse of the daily performance or an inverse multiple of the daily performance of an index. The Ultra ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Ultra” or UltraPro” in their names) are designed to correspond to a multiple of the daily performance of an index. The Funds, except the Matching ProShares Funds, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF, do not seek to achieve their stated investment objective over a period of time greater than a single day. A “single day” is measured from the time the Fund calculates its net asset value (“NAV”) to the time of the Fund’s next NAV calculation. Each Matching ProShares Fund, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF seeks to achieve its stated investment objective both on a single day and over time. The Managed Futures Strategy ETF is actively managed and seeks to provide positive returns that are not directly correlated to broad equity or fixed income markets. The Crude Oil Strategy ETF is actively managed and seeks to provide exposure to the West Texas Intermediate crude oil futures markets. The CDS Short North American HY Credit ETF is actively managed and seeks to provide short exposure to the credit of debt issuers. The Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and bitcoin futures contracts. The Short Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and short exposure to bitcoin futures contracts. The Bitcoin Futures/Equity Strategy ETF is actively managed and seeks total return through investment in U.S. equity securities and bitcoin futures contracts. The Blockchain/Bitcoin Strategy ETF is actively managed and seeks total return through investment in the equity securities of blockchain technology companies and exposure to bitcoin investments.
FOREIGN SOVEREIGN, SUB-SOVEREIGN, QUASI SOVEREIGN AND SUPRANATIONAL SECURITIES. The Funds may invest in fixed-rate debt securities issued by: non-U.S. governments (foreign sovereign bonds); local governments, entities or agencies of a non-U.S. country (foreign sub-sovereign bonds); corporations with significant government ownership (“Quasi-Sovereigns”); or two or more central governments or institutions (supranational bonds). These types of debt securities are typically
Let's not even go into the paradigm shift that this development implies. The growth of a bitcoin futures market positions it even more as a commodity than a currency (in the US, the Commodity Futures Trading Commission regulates futures markets). And even more as an investment asset than a technology that has the potential to change the plumbing of finance.

cooperatives) is a record holder of a Share in a Fund that recognizes “excess inclusion income,” then the Fund will be subject to a tax on that portion of its “excess inclusion income” for the taxable year that is allocable to such shareholders at the highest federal corporate income tax rate. The extent to which this IRS guidance remains applicable in light of the December 2006 legislation is unclear. To the extent permitted under the 1940 Act, each Fund may elect to specially allocate any such tax to the applicable CRT, or other shareholder, and thus reduce such shareholder’s distributions for the year by the amount of the tax that relates to such shareholder’s interest in the Fund. The Funds have not yet determined whether such an election will be made.
​Trading these futures instead of actual bitcoins is smart because you are able to access higher leverage by entering contracts with counterparties, while keeping your coins safe in cold storage or elsewhere. Additionally, unlike trading margin on Kraken or Bitfinex, you do NOT have to pay interest on the leverage you have! This is the result of the counterparty structure of futures. High leverage trading, low-fees, and high profit potential.
•   If a Fund qualifies for treatment as a regulated investment company, it is not subject to federal income tax on net investment income and net realized capital gains that the Fund timely distributes to its shareholders. If a Fund were to fail to so qualify, and were ineligible to or otherwise did not cure such failure, its taxable income and gains would be subject to tax at the Fund level, and distributions from earnings and profits would be taxable to shareholders as ordinary income.
The Trust reserves the absolute right to reject a purchase order transmitted to it by the Distributor in respect of any Fund if (a) the purchaser or group of purchasers, upon obtaining the Shares ordered, would own 80% or more of the currently outstanding Shares of any Fund; (b) the Deposit Securities delivered are not as specified by ProShare Advisors and ProShare Advisors has not consented to acceptance of an in-kind deposit that varies from the designated Deposit Securities; (c) acceptance of the purchase transaction order would have certain adverse tax consequences to the Fund; (d) the acceptance of the purchase transaction order would, in the opinion of counsel, be unlawful; (e) the acceptance of the purchase order transaction would otherwise, in the discretion of the Trust or ProShare Advisors, have an adverse effect on the Trust or the rights of beneficial owners; (f) the value of a Cash Purchase Amount, or the value of the Balancing Amount to accompany an in-kind deposit, exceeds a purchase authorization limit extended to an Authorized Participant by the Custodian and the Authorized Participant has not deposited an amount in excess of such purchase authorization with the Custodian prior to the relevant cut-off time for the Fund on the transmittal date; or (g) in the event that circumstances outside the control of the Trust, the Distributor and ProShare Advisors make it impractical to process purchase orders. The Trust shall notify a prospective purchaser of its rejection of the order of such person. The Trust and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of purchase transaction orders nor shall either of them incur any liability for the failure to give any such notification.
Each of the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF (each, a “Parent Fund”) intends to achieve commodity exposure through investment in the ProShares Cayman Portfolio I, the ProShares Cayman Crude Oil Portfolio, the ProShares Cayman Bitcoin Futures Strategy Portfolio the ProShares Cayman Short Bitcoin Futures Strategy Portfolio, the ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio and the ProShares Cayman Bitcoin/Blockchain Strategy Portfolio respectively, each a wholly-owned subsidiary of its respective Parent Fund (each, a “Subsidiary”) organized under the laws of the Cayman Islands. Each Parent Fund’s investment in its respective Subsidiary is intended to provide such Parent Fund with exposure to commodity and financial markets in accordance with applicable rules and regulations. Each Subsidiary may invest in derivatives, including futures, forwards, option and swap contracts, notes and other investments intended to serve as margin or collateral or otherwise support the Subsidiary’s derivatives positions. Neither Subsidiary is registered under the 1940 Act, and neither Subsidiary will have all of the protections offered to investors in RICs. The Board, however, has oversight responsibility for the investment activities of each Parent Fund, including its investment in its respective Subsidiary, and the Parent Fund’s role as the sole shareholder of the Subsidiary.
In order to provide current Share pricing information, an Exchange disseminates an updated Indicative Optimized Portfolio Value (“IOPV”) for each Fund. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no warranty as to the accuracy of the IOPVs. IOPVs are expected to be disseminated on a per Fund basis every 15 seconds during regular trading hours of an Exchange.

You’ll find that different exchanges cater to different markets. Today, most countries have at least one cryptocurrency exchange specializing in their own currency. There are exchanges that can accept New Zealand Dollars in exchange for bitcoin, for example. Other exchanges are known for certain pairs. Bithumb, for example, has particularly strong liquidity in the ETH/KRW (South Korean Won) pair at the moment (and it’s easily the most popular cryptocurrency exchange in Korea).

Investment in mortgage-backed securities poses several risks, including among others, prepayment, market and credit risk. Prepayment risk reflects the risk that borrowers may prepay their mortgages faster than expected, thereby affecting the investment’s average life and perhaps its yield. Whether or not a mortgage loan is prepaid is almost entirely controlled by the borrower. Borrowers are most likely to exercise prepayment options at the time when it is least advantageous to investors, generally prepaying mortgages as interest rates fall, and slowing payments as interest rates rise. Besides the effect of prevailing interest rates, the rate of prepayment and refinancing of mortgages may also be affected by appreciation in home values, ease of the refinancing process and local economic conditions. Market risk reflects the risk that the price of a security may fluctuate over time. The price of mortgage-backed securities may be particularly sensitive to prevailing interest rates, the length of time the security is expected to be outstanding, and the liquidity of the issue. In a period of unstable interest rates, there may be decreased demand for certain types of mortgage-backed securities, and each Fund invested in such securities wishing to sell them may find it difficult to find a buyer, which may in turn decrease the price at which they may be sold. Credit risk reflects the risk that a Fund may not receive all or part of its principal because the issuer or credit enhancer has defaulted on its obligations. Obligations issued by U.S. government-related entities are guaranteed as to the payment of principal and interest, but are not backed by the full faith and credit of the U.S. government. The performance of private label mortgage-backed securities, issued by private institutions, is based on the financial health of those institutions. With respect to GNMA certificates, although GNMA guarantees timely payment even if homeowners delay or default, tracking the “pass-through” payments may, at times, be difficult.
At or before the maturity of a forward currency contract, the Funds may either sell a portfolio security and make delivery of the currency, or retain the security and terminate its contractual obligation to deliver the currency by buying an “offsetting” contract obligating them to buy, on the same maturity date, the same amount of the currency. If the Fund engages in an offsetting transaction, it may later enter into a new forward currency contract to sell the currency.

The most common way to trade in Bitcoin and other cryptocurrency derivatives today is through contract-for-difference (CFD) contracts. These CFD contracts are usually traded over the counter (OTC), meaning that they are not traded on exchanges but directly between participants. Due to the high volatility (exceeding 1.5-2x std from the mean) most of the OTC platforms do not provide leverage on bitcoin and other cryptos CFDs.
