The right of redemption may be suspended or the date of payment postponed with respect to any Fund (1) for any period during which the Exchange is closed (other than customary weekend and holiday closings); (2) for any period during which trading on the Exchange is suspended or restricted; (3) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its NAV is not reasonably practicable; (4) in such other circumstance as is permitted by the SEC; or (5) for up to 14 calendar days for any of the Global Funds or Short or Ultra International ProShares Funds during an international local holiday, as described below in “Other Information”.
Note that you could just keep bitcoin on CryptoFacilities waiting to make the trade so you don't have to wait to move the bitcoin you bought over. This is called see-saw arbitrage model, where you keep funds on both exchanges to avoid having to wait. This is fine, but you can't ignore that there is extra capital being used in the play, so it affects your rate of return and capital utilisation. We will not use this method, we will do a full, complete, legitimate arbitrage process.
Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[30] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
The regulation of bitcoin, digital assets and related products and services continues to evolve. The inconsistent and sometimes conflicting regulatory landscape may make it more difficult for bitcoin businesses to provide services, which may impede the growth of the bitcoin economy and have an adverse effect on consumer adoption of bitcoin. There is a possibility of future regulatory change altering, perhaps to a material extent, the nature of an investment in the Funds or the ability of the Funds to continue to operate. Additionally, to the extent that bitcoin itself is determined to be a security, commodity future or other regulated asset, or to the extent that a United States or foreign government or quasi-governmental agency exerts regulatory authority over the Bitcoin Network, bitcoin trading or ownership in bitcoin, the price of bitcoin and the value of the Bitcoin Instruments may be adversely affected, which may have an adverse effect on the value of your investment in the Funds. In sum, bitcoin regulation takes many different forms and will, therefore, impact bitcoin and its usage in a variety of manners. The European Union has recently agreed to rules designed to reduce anonymity of bitcoin transactions, which may impact the supply and demand for bitcoin and bitcoin futures contracts.

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.
Now, if that margin-call does not get filled and the price continues to fall, then I'm making profits on my contract but nobody is paying for it since the counterparty who got margin-called didn't get the liquidation order filled. So what happens is that at settlement time of the contract, that unfilled liquidation loss to the system will be deducted from the profits of ALL traders before they are distributed.
Certain of the Funds are likely to obtain substantial exposure to the price movements of bitcoin by holding bitcoin linked exchange-traded notes (“ETNs”) that provide exposure to the price of bitcoin. ETNs are unsecured, unsubordinated debt securities of an issuer that are listed and traded on a U.S. stock exchange. An ETN’s returns are generally linked to the performance of a particular market benchmark or strategy minus applicable fees. ETNs do not provide principal protection and may or may not make periodic coupon payments. ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due. Additionally, the value of an ETN may be influenced by time to maturity, level of supply and demand, volatility and lack of liquidity in the underlying market (e.g., the commodities market), changes in interest rates or the issuer’s credit rating, and other economic, legal, political or geographic events. The value of an investment in an ETN may be impacted by fees associated with the ETN. Structural aspects of the ETNs may impact their market value. Trading by affiliates of an ETN sponsor may create conflicts of interest. The issuer of an ETN may be unable to meet its obligations. The potential impact of Bitcoin Network forks on the value of a bitcoin ETN is unclear. ETNs issued by special purpose vehicles may include greater risk. ETNs are subject to risks associated with the underlying asset.
•   New Fund Risk — The Fund recently commenced operations, has a limited operating history, and started operations with a small asset base. There can be no assurance that the Fund will be successful or grow to or maintain a viable size, that an active trading market for the Fund’s shares will develop or be maintained, or that the Fund’s shares’ listing will continue unchanged.
A Fund may cover its sale of a call option on a futures contract by taking a long position in the underlying futures contract at a price less than or equal to the strike price of the call option, or, if the long position in the underlying futures contract is established at a price greater than the strike price of the written (sold) call, the Fund will earmark/segregate liquid instruments equal in value to the difference between the strike price of the call and the price of the future. A Fund may also cover its sale of a call option by taking positions in instruments whose prices are expected to move relatively consistently with the call option. A Fund may cover its sale of a put option on a futures contract by taking a short position in the underlying futures contract at a price greater than or equal to the strike price of the put option, or, if the short position in the underlying futures contract is established at a price less than the strike price of the written put, the Fund will segregate cash or liquid instruments equal in value to the difference between the strike price of the put and the price of the future. A Fund may also cover its sale of a put option by taking positions in instruments whose prices are expected to move relatively consistently to the put option.
 	•	 	A decline in the adoption of bitcoin could have a negative effect on the price of bitcoin and bitcoin-related investments. Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. However, there can be no guarantees this growth will continue. Further, adoption of bitcoin as a means of payment has been limited when compared with the increase in the price of bitcoin, indicating that the majority of bitcoin’s use is for investment and speculative purposes. A lack of acceptance of bitcoin as a means of payment could negatively impact the price of the Bitcoin Futures contracts in which the Fund invests.

  •   Inverse Correlation Risk — Since a portion of the Fund’s assets are invested in short positions in bitcoin futures contracts, the Fund will likely decline in value when the price of bitcoin futures contracts goes up (unless such losses are offset by gains in the value of the Fund’s positions in other investments), a result that is the opposite from the results of taking long positions in bitcoin futures contracts.
Bitcoin trading occurs on exchanges. These exchanges accept your fiat currencies (like USD and EUR) in exchange for a cryptocurrency (like BTC). These exchanges maintain a liquid pool of bitcoin, allowing users to withdraw their bitcoin at any time. Investors who wish to trade on that exchange can deposit bitcoin into their personal wallet on the exchange, or make a wire transfer to the exchange’s bank account. The exchange notices this transfer, then credits your account.
  3. Make loans to other persons, except that the acquisition of bonds, debentures or other corporate debt securities and investment in government obligations, commercial paper, pass-through instruments, certificates of deposit, bankers’ acceptances and repurchase agreements and purchase and sale contracts and any similar instruments shall not be deemed to be the making of a loan, and except, further, that the Fund may lend its portfolio securities, provided that the lending of portfolio securities may be made only in accordance with applicable law and the guidelines set forth in the Prospectus and this SAI, as they may be amended from time to time.
These days, all of the BTC/USD contracts trading at active futures markets are inverse, as mentioned in the beginning of this guide. The only differences between the exchanges is how they trigger liquidations and the procedure for handling margin calls. They all use Bitcoin as the currency, of course, and you can use the table below for a basic feature comparison:
When Bitconnect was exposed as a 100% scam and was shut down, the price dropped vertically to almost zero. But then, it bounced back up by something like 15-30 percent, and it kept going up for a couple of days. This is caused, in my opinion, by the fact that bots and cavemen technical analysts, who never follow the news, look at the chart and think “this is a great time to buy”.
SEI Investments Distribution Co. (“SEI”) serves as the distributor and principal underwriter in all fifty states and the District of Columbia. SEI is located at One Freedom Valley Drive, Oaks, PA 19456. The Distributor has no role in determining the investment policies of the Trust or any of the Funds, or which securities are to be purchased or sold by the Trust or any of the Funds.

•   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.
Municipal notes with maturities of three years or less are usually given note ratings (designated SP-1 or SP-2) to distinguish more clearly the credit quality of notes as compared to bonds. Notes rated SP-1 have a very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are given the designation of SP-1+. Notes rated SP-2 have a satisfactory capacity to pay principal and interest.

Transaction fees payable to the Trust are imposed to compensate the Trust for the transfer and other transaction costs of a Fund associated with the issuance and redemption of Creation Units of Shares. A fixed Transaction Fee is applicable to each creation or redemption transaction, regardless of the number of Creation Units purchased or redeemed. In addition, a variable Transaction Fee equal to a percentage of the value of each Creation Unit purchased or redeemed may be applicable to a creation or redemption transaction. Purchasers of Creation Units of the Matching and Ultra ProShares Funds for cash may also be required to pay an additional charge to compensate the relevant Fund for brokerage, market impact or other expenses. Where the Trust permits an in-kind purchaser to substitute cash in lieu of depositing a portion of the Deposit Securities, the purchaser will be assessed an additional charge for cash purchases. The maximum Transaction Fee on purchases and redemptions will be 2.00% of the NAV of any Creation Unit, except that for the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a Transaction Fee up to 3.00% will be charged on the cash used in lieu of depositing all or a portion of the Deposit Securities or the cash portion of any redemption transaction. The Transaction Fees charged to each Fund are presented in the Authorized Participant Handbook.
Each Fund’s portfolio turnover rate, to a great extent, will depend on the purchase, redemption and exchange activity of the Fund’s investors. A Fund’s portfolio turnover may vary from year to year, as well as within a year. The nature of the Funds may cause the Funds to experience substantial differences in brokerage commissions from year to year. The overall reasonableness of brokerage commissions is evaluated by the Advisor based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. High portfolio turnover and correspondingly greater brokerage commissions depend, to a great extent, on the purchase, redemption, and exchange activity of a Fund’s investors, as well as each Fund’s investment objective and strategies. Consequently, it is difficult to estimate what each Fund’s actual portfolio turnover rate will be in the future. However, it is expected that the portfolio turnover experienced by the Funds from year to year, as well as within a year, may be substantial. A higher portfolio turnover rate would likely involve correspondingly greater brokerage commissions and transaction and other expenses that would be borne by the Funds. The nature of the Funds may cause the Funds to experience substantial differences in brokerage commissions from year to year. The overall reasonableness of brokerage commissions is evaluated by the Advisor based upon its knowledge of available information as to the general level of commissions paid by other institutional investors for comparable services. In addition, a Fund’s portfolio turnover level may adversely affect the ability of the Fund to achieve its investment objective. “Portfolio Turnover Rate” is defined under the rules of the SEC as the value of the securities purchased or securities sold, excluding all securities whose maturities at time of acquisition were one year or less, divided by the average monthly value of such securities owned during the year. Based on this definition, instruments with remaining maturities of less than one year, including swap agreements, options and futures contracts in which the Funds invest, are excluded from the calculation of Portfolio Turnover Rate for each Fund. For those Funds that commenced operations prior to May 31, 2017, each such Fund’s turnover rate information is set forth in the annual report to shareholders. Portfolio turnover rates are also shown in each Fund’s summary prospectus.
•   Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the bitcoin futures contracts in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of ProShare Advisors. Markets may be disrupted by a number of events, including but not limited to cyber-attacks, economic crises, natural disasters, new legislation, or regulatory changes inside or outside the U.S.
Bitcoin and other cryptocurrencies have evolved from a playful experiment among technical experts to an established and growing branch of the global financial industry. This means that the times in which cryptocurrency traders and investors only concerned themselves with straightforward buying and selling are over. Derivatives are now entering the picture.
