Distributions by the Fund to foreign shareholders other than Capital Gain Dividends, short-term capital gain dividends and interest-related dividends (e.g., dividends attributable to foreign-source dividend and interest income or to short-term capital gains or U.S. source interest income to which the exception from withholding described above does not apply) are generally subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate).
COVERED BONDS. The Funds may invest in covered bonds, which are debt securities issued by banks or other credit institutions that are backed by both the issuing institution and underlying pool of assets that compose the bond (a “cover pool”). The cover pool for a covered bond is typically composed of residential or commercial mortgage loans or loans to public sector institutions. A covered bond may lose value if the credit rating of the issuing bank or credit institution is downgraded or the quality of the assets in the cover pool deteriorates.
Securities (including short-term securities) and other assets are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. Futures contracts and options on securities, indexes and futures contracts are generally valued at their last sale price prior to the time at which the NAV per share of a class of shares of a Fund is determined. Alternatively, fair valuation procedures as described below may be applied if deemed more appropriate. Routine valuation of certain other derivatives is performed using procedures approved by the Board of Trustees.
Bitcoin is a relatively new type of currency—a digital or cryptocurrency secured through cryptography, or codes that can’t be read without a key. Traditional currencies are made up of paper bills and coins. Unlike traditional currencies, the bitcoin is not issued by any central government. Rather, a computer algorithm determines how many bitcoins are produced and added to the economy. This is much different than a traditional currency, where central banks typically determine how much money to print.
Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described below under “Purchase and Issuance of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor also acts as agent for the Trust. The Distributor will deliver a Prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority, Inc. The Distributor has no role in determining the investment policies of the Funds or which securities are to be purchased or sold by the Funds.

A mortgage-backed security is a type of pass-through security, which is a security representing pooled debt obligations repackaged as interests that pass income through an intermediary to investors. Each Fund may invest in mortgage-backed securities, as “cover” for the investment techniques these Funds employ. In the case of mortgage-backed securities, the ownership interest is in a pool of mortgage loans.
Always pay attention to Bitcoin. Most altcoins (every cryptocurrency except Bitcoin) are pegged more closely to Bitcoin than Asian currencies were to the USD during the Asian Financial Crisis. If Bitcoin price pump drastically, altcoins price can go down as people try to exit altcoins to ride the BTC profits; inversely, if Bitcoin prices dump drastically, altcoin prices can go down, too, as people exit altcoins to exchange back into fiat. The best times for altcoin growth appear when Bitcoin shows organic growth or decline, or remains stagnant in price.

Cryptocurrencies are a potential tool to evade economic sanctions for example against Russia, Iran, or Venezuela. In April 2018, Russian and Iranian economic representatives met to discuss how to bypass the global SWIFT system through decentralized blockchain technology.[72] Russia also secretly supported Venezuela with the creation of the petro (El Petro), a national cryptocurrency initiated by the Maduro government to obtain valuable oil revenues by circumventing US sanctions.[73]

ensure the delivery of the requisite number of Fund Shares through DTC to the Custodian by no later than 10:00 a.m. Eastern Time of the second Business Day (T+2) immediately following the transmittal date. Authorized Participants should be aware that the deadline for such transfers of Fund Shares through the DTC system may be significantly earlier than the close of business on the primary listing exchange. Those making redemption requests should ascertain the deadline applicable to transfers of Fund Shares through the DTC system by contacting the operations department of the broker or depositary institution affecting the transfer of Fund Shares. The Balancing Amount, if any, must be transferred in U.S. dollars directly to the Custodian through the Federal Reserve Bank wire transfer system in a timely manner so as to be received by the Custodian no later than 2:00 p.m. Eastern Time on the second Business Day (T+2) immediately following the transmittal date. If the Custodian does not receive both the required Fund Shares and the Balancing Amount, if any, by 10:00 a.m. and 2:00 p.m., respectively, on the second Business Day (T+2) immediately following the transmittal date, such order will be deemed not in proper form and cancelled.
A Fund may invest in one or more exchange-traded funds that invest in commodities or options, futures, or forwards with respect to commodities, and are treated as QPTPs for federal income tax purposes. As noted above, a Fund is limited to investing no more than 25% of the value of its total assets in the securities of one or more QPTPs. Although income from QPTPs is generally qualifying income, if an ETF intending to qualify as a QPTP fails to so qualify and is treated as a partnership for U.S. federal income tax purposes, a portion of its income may not be qualifying income. It is also possible that an ETF intending to qualify as a QPTP will be treated as a corporation for federal income tax purposes. In such a case, it will be potentially liable for an entity-level corporate income tax, which will adversely affect the return thereon. There can be no guarantee that any ETF will be successful in qualifying as a QPTP. In addition, there is little regulatory guidance concerning the application of the rules governing qualification as a QPTP, and it is possible that future guidance may adversely affect the qualification of ETFs as QPTPs. A Fund’s ability to pursue an investment strategy that involves investments in QPTPs may be limited by that Fund’s intention to qualify as a RIC, and may bear adversely on that Fund’s ability to so qualify.

When the market for certain 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 bitcoin futures contracts would take place at a price that is lower than the price of the more distant bitcoin futures contracts. This pattern of higher futures prices for longer expiration bitcoin futures contracts is often referred to as “contango.” Alternatively, when the market for certain bitcoin 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 bitcoin futures contracts would take place at a price that is higher than the price of the more distant bitcoin futures contracts. This pattern of higher future prices for shorter expiration bitcoin futures contracts is referred to as “backwardation.”

Crypto Facilities and the CME Group  have been calculating and publishing the Bitcoin Reference Rate (BRR) since November 2016. Such an official rate is a prerequisite of options trading in the traditional markets. The BRR is calculated based on the rates from the biggest exchanges: Bitstamp, GDAX, itBit, and Kraken. More concretely, it is calculated based on all Bitcoin vs. USD trades on the participating exchanges between 3 and 4 p.m. London time. To calculate the BRR, the hour between 3 and 4 is divided into 12 intervals of 5 minutes. For each interval, the volume-weighted median of the Bitcoin price is calculated (statistically, the median, in contrast to the average, prevents single outliers from distorting the price). The BRR is then the average of these 12 median values. More details about the calculation of the BRR can be found in the BRR whitepaper.
Each Fund may invest in money market instruments, which short-term cash instruments that have a remaining maturity of 397 days or less and exhibit high credit profiles, or cash or cash equivalents such as other high credit quality, short-term fixed income or similar securities, including (i) money market funds, (ii) U.S. Treasury Bills, which are U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government, and (iii) Repurchase Agreements, which are contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy them back at a specified time and price. Repurchase agreements are primarily used by the Funds as a short-term investment vehicle for cash positions.
Investors in the ProShares Short Bitcoin Futures Strategy ETF should understand the consequences of the “short” strategy employed by the Fund, which is subject to, among others, compounding and market volatility risk. The Fund may adjust its short exposure as frequently as daily basis which entails obtaining additional short exposure as the Fund experiences gains, and reducing short exposure as the Fund experiences losses. As a result, the Fund’s performance may be more vulnerable to the effects of compounding than funds that do not seek to provide short investment exposure. During periods of high volatility, this risk may be exacerbated and the Fund may have losses as a result of such adjustments.
•   Interest Rate Risk — The Fund intends to invest a substantial portion of its assets in U.S. Treasury securities and is subject to interest rate risk. Interest rate risk is the risk that debt securities may fluctuate in value due to changes in interest rates. Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities may fluctuate more in response to interest rate changes than securities with shorter maturities. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). This risk may be elevated under current economic conditions because interest rates are at historically low levels. Returns on investment in debt instruments may trail the returns on other investment options, including investments in equity securities.

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.

You will then be able to trade futures contracts just like they are bitcoin spot. If price goes up on spot, a good futures exchange will have its contracts also going up in price, and then you can sell and get out. However, the price of the futures contract is dependent on others trading it. So if nobody else is trading it and bringing the market price of the contract along with changes in the underlying asset, then it's useless and you are forced to hold it until settlement to realize any of the profit/loss from the position.
A Bitcoin futures contract is exactly what you would expect from the example above, replacing pork bellies with Bitcoin. It is a contract that enables you to buy Bitcoin at a predetermined price at a specific point in the future. For example, if today’s Bitcoin price is 8,000 USD per BTC and you expect it to rise to 10,000 USD per BTC in 4 weeks, then entering a contract which allows you to buy Bitcoin at 9,000 USD in 4 weeks is highly attractive.
