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.
  •   An interruption in Internet service or a limitation of Internet access could have a negative impact on bitcoin. The Bitcoin Network relies on users access to the Internet. A significant disruption of Internet connectivity could impede the functionality of the Bitcoin Network and adversely affect the price of bitcoin. Any technical disruptions or regulatory limitations that affect Internet access may have an adverse effect on the Bitcoin Network, the price of bitcoin and the bitcoin futures contracts in which the Fund invests. In addition to technical disruptions such as cyber-attacks, the potential elimination of the net neutrality regulations in the U.S. may have a negative impact on bitcoin and the Bitcoin ecosystem.
Various government agencies, departments, and courts have classified bitcoin differently. China Central Bank banned the handling of bitcoins by financial institutions in China in early 2014.[69] In Russia, though cryptocurrencies are legal, it is illegal to actually purchase goods with any currency other than the Russian ruble.[70] Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[71]
The CME Group contract (symbol "BTC") began trading on December 18, 2017, building off of the success of the BRR and demand for a regulated trading venue for the digital asset market. The contract is cash-settled, based on the CME CF Bitcoin Reference Rate (BRR) which serves as a once-a-day reference rate of the U.S. dollar price of bitcoin. Bitcoin futures are listed on and subject to the rules of CME.2

•   Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShare Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies. The Fund does not seek to provide investment performance that would be opposite of a 30% investment in bitcoin futures contracts and a 70% investment in U.S. government securities.
•   Rolling Futures Contract Risk — The Fund will invest in and have exposure to bitcoin futures contracts and is subject to risks related to “rolling” such contracts. Rolling occurs when the Fund closes out of a futures contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold futures contracts through expiration, but instead intends to “roll” its futures positions. When the market for these futures contracts is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the rolling process of the more nearby contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher futures contract prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for futures contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the rolling process of the more nearby contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher futures prices for shorter expiration futures contracts is referred to as “backwardation.” Extended periods of contango could cause significant losses for the Fund. The Advisor will utilize active management techniques to seek to mitigate the negative impact or, in certain cases, benefit from the contango or backwardation present in the various futures contract markets, but there can be no guarantee that it will be successful in doing so.
The Fund generally does not expect to invest directly in futures contracts, option contracts and swap agreements (“Bitcoin Instruments”). The Fund expects to gain exposure to these investments by investing a portion of its assets in the ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio, a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by ProShare Advisors, the Fund’s investment advisor, and invests directly in Bitcoin Instruments. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Fund’s investment in the Subsidiary is intended to provide the Fund with exposure to commodity markets related to bitcoin in accordance with applicable rules and regulations. The Fund will invest up to 25% of its total assets in the Subsidiary. Except as otherwise noted, references to the Fund’s investment strategies and risks include the investment strategies and risks of the Subsidiary.

Each Fund may also enter into reverse repurchase agreements, which may be viewed as a form of borrowing, with financial institutions. However, under current pronouncements, to the extent a Fund “covers” its repurchase obligations, as described above in “Reverse Repurchase Agreements,” such agreement will not be considered to be a “senior security” and, therefore, will not be subject to the 300% asset coverage requirement otherwise applicable to borrowings by that Fund.
Several factors may affect a Fund’s ability to achieve a high degree of correlation with its benchmark. Among these factors are: (i) a Fund’s fees and expenses, including brokerage (which may be increased by high portfolio turnover) and the costs associated with the use of derivatives; (ii) less than all of the securities underlying a Fund’s benchmark being held by the Fund and/or securities not included in its benchmark being held by a Fund; (iii) an imperfect correlation between the performance of instruments held by a Fund, such as futures contracts, and the performance of the underlying securities in a benchmark; (iv) bid-ask spreads (the effect of which may be increased by portfolio turnover); (v) holding instruments traded in a market that has become illiquid or disrupted; (vi) a Fund’s share prices being rounded to the nearest cent; (vii) changes to the benchmark that are not disseminated in advance; (viii) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements;

!! WARNING !!! Note that on CryptoFacilities each contract is denominated by 1 BTC. So if you bought a fraction of BTC you can NOT perform a perfect hedge of the value. If you round the BTC you bought with start capital down, you will have slight overexposure LONG with the left-over BTC. If you round up and short an extra contract, you will have slight overexposure SHORT.
