•   Foreign Investments Risk — Investing in securities of foreign issuers may provide the Fund with increased risk. Various factors related to foreign investments may negatively impact the Fund’s performance, such as: i) fluctuations in the value of the applicable foreign currency; ii) differences in securities settlement practices; iii) uncertainty associated with evidence of ownership of investments in countries that lack centralized custodial services; iv) possible regulation of, or other limitations on, investments by U.S. investors in foreign investments; v) potentially higher brokerage commissions; vi) the possibility that a foreign government may withhold portions of interest and dividends at the source; vii) taxation of income earned in foreign countries or other foreign taxes imposed; viii) foreign exchange controls, which may include suspension of the ability to transfer currency from a foreign country; ix) less publicly available information about foreign issuers; x) changes in the denomination currency of a foreign investment; and xi) less certain legal systems in which the Fund might encounter difficulties or be unable to pursue legal remedies. Foreign investments also may be more susceptible to political, social, economic and regional factors than might be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined. Until the transactions are effected, the Fund is exposed to increased foreign currency risk and market risk.
Margin-trading is what provides the real reward and potential in daytrading bitcoin. You will be able to access the leverage to profit well from relatively small moves in BTC/USD price. High risk, high reward, high potential for loss. However, you need not use Futures only to speculate, hedging on lower leverage is also a great use case for Bitcoin derivatives if you just want to defend your coins. 
Margin Call - when you run out of bitcoin on your account to cover the contract positions you have taken (your account value doesn't cover the Maintance Margin) you are officially rekt. Some exchanges like CryptoFacilities will merely notify you that you have to deposit more or reduce your positions to increase your margin. Others like BitMEX will liquidate you at this level where the exchange takes over your position to liquidate it into the market to prevent system loss.
Each Fund may engage in transactions in index options listed on national securities exchanges or traded in the OTC market as an investment vehicle for the purpose of realizing the Fund’s investment objective. The exercising holder of an index option receives, instead of the asset, cash equal to the difference between the closing level of the index and the exercise price of the option. Some index options are based on a broad market index such as the Standard & Poor’s (“S&P”) 500® Index, the New York Stock Exchange, Inc. (“NYSE”) Composite Index or on a narrower index such as the Philadelphia Stock Exchange Over-the-Counter Index. Options currently are traded on the Chicago Board Options Exchange, the NYSE Amex Options and other exchanges (collectively, “Exchanges”). Purchased OTC options and the cover for written OTC options will be subject to the relevant Fund’s 15% limitation on investment in illiquid securities. See “Illiquid Securities” below. When required by law, a Fund will segregate liquid assets in an amount equal to the value of the Fund’s total assets committed to the consummation of such options. Obligations under options so covered will not be considered senior securities for purposes of a Fund’s investment restriction concerning senior securities.
reduce the amount of the Fund’s borrowings to the extent necessary to meet this 300% coverage requirement. Maintenance of this percentage limitation may result in the sale of portfolio securities at a time when investment considerations would not favor such sale. In addition to the foregoing, the Funds are authorized to borrow money as a temporary measure for extraordinary or emergency purposes in amounts not in excess of 5% of the value of each Fund’s total assets. This borrowing is not subject to the foregoing 300% asset coverage requirement. The Funds are authorized to pledge portfolio securities as ProShare Advisors deems appropriate in connection with any borrowings.
  •   Developmental risk. Blockchain technology is not a product or service within an individually attributable revenue stream. Blockchain technology may never develop optimized transactional processes that lead to realized economic returns for any company in which the Fund invests. Blockchain Companies that are developing applications of blockchain technology applications may not in fact do so or may not be able to capitalize on those blockchain technologies. The development of new or competing platforms may cause consumers and investors to use alternatives to blockchains.
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.

The value of such Creation Unit for the Equities for Rising Rates ETF, the S&P MidCap 400 Dividend Aristocrats ETF, the Russell 2000 Dividend Growers ETF, the MSCI Emerging Markets Dividend Growers ETF, the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the UltraPro Short Nasdaq Biotechnology ETF, the Short 7-10 Year Treasury ETF and the Ultra Gold Miners ETF as of each Fund’s inception was $1,000,000.
As a general matter, the Short ProShares Funds, the CDS Short North American HY Credit ETF and the Short Bitcoin Futures Strategy ETF respond differently in response to market conditions than the Matching ProShares Funds, the Ultra ProShares Funds, the Managed Futures Strategy ETF or the Crude Oil Strategy ETF. The terms “favorable market conditions” and “adverse market conditions,” as used in this SAI, are Fund-specific.
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.”

Transactions in options, futures, forward contracts, swaps and certain positions undertaken by the Funds may result in “straddles” for federal income tax purposes. The straddle rules may affect the character of gains (or losses) realized by a Fund, and losses realized by the Fund on positions that are part of a straddle may be deferred under the straddle rules, rather than being taken into account in calculating taxable income for the taxable year in which the losses are realized. In addition, certain carrying charges (including interest expense) associated with positions in a straddle may be required to be capitalized rather than deducted currently. Certain elections that a Fund may make with respect to its straddle positions may also affect the amount, character and timing of the recognition of gains or losses from the affected positions.
It is important to note, however, that leverage means that your potential losses may also be much higher. If pork belly prices fall, call options lose value in a much higher proportion than the pork bellies themselves. In the above example, if the price of pork bellies falls from 1,000 to 900 USD (by 10%), the price of call options may fall from 10.5 USD to almost zero, resulting in a near-total loss of your funds instead of a small loss of just 10%.
