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:
general obligations of the issuer and are typically guaranteed by such issuer. Despite this guarantee, such debt securities are subject to default, restructuring or changes to the terms of the debt to the detriment of security holders. Such an event impacting a security held by a Fund would likely have an adverse impact on the Fund’s returns. Also, due to demand from other investors, certain types of these debt securities may be less accessible to the capital markets and may be difficult for a Fund to source. This may cause a Fund, at times, to pay a premium to obtain such securities for its own portfolio. For more information related to foreign sovereign, sub-sovereign and supranational securities, see “Foreign Securities” and “Exposure to Securities or Issuers in Specific Foreign Countries or Regions” above.
Creation Units of Shares may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor. Such Authorized Participant will agree pursuant to the terms of such Authorized Participant Agreement on behalf of itself or any investor on whose behalf it will act, as the case may be, to certain conditions, including that such Authorized Participant will make available an amount of cash sufficient to pay the Balancing Amount, defined below, and the Transaction Fee, described below in “Transaction Fees”. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Balancing Amount. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement, and that therefore orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants.
A futures curve shows the forward expectation of an asset’s price. Future rates of an asset can be calculated by extrapolating price from the risk-free theoretical spot rate of the asset. For example, one might calculate the possible future rate of an asset for the short (<1 month), medium (1-3 months) and long term (>3 months). In other words, future curves represent the demand for a specific asset and therefore the expected price evolution for the asset projected into the future. The curve is constructed from a discrete set of data points for various maturities. Initially, futures curves were used for hedging purposes, but with the evolution of the investment management industry, futures curves have become basic investment instruments not only for traditional commodities but also for new emerging asset classes.
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.
and the FTSE Developed Europe Index (the “Indices”) (ii) the figure at which an Index is said to stand at any particular time on any particular day or otherwise, or (iii) the suitability of the Index for the purpose to which it is being put in connection with the ProShares Ultra, Short and UltraShort FTSE China 50 and Ultra and UltraShort FTSE Developed Europe. None of the Licensor Parties have provided or will provide any financial or investment advice or recommendation in relation to the Index to ProShares or its clients. The Index is calculated by FTSE or its agent. None of the Licensor Parties shall be (a) liable (whether in negligence or otherwise) to any person for any error in the Index and (b) under any obligation to advise any person of any error therein.

Inverse bitcoin contracts are usually denominated in USD terms. So if there's a contract value of $100 then each side -- LONG and SHORT -- puts down some portion of the contract value in margin. The contract is an agreement between traders to pay the other side an amount of bitcoin profit/loss as the price changes. Each contract has an expiration date, and some exchanges have periodic (daily or weekly) dates where the contract period's profits are "settled" even if the contract has not expired.
Under Treasury regulations, if a shareholder recognizes a loss on a disposition of a Fund’s Shares of $2 million or more for an individual shareholder or $10 million or more for a corporate shareholder (including, for example, an insurance company holding separate account), the shareholder must file with the IRS a disclosure statement on Form 8886. Direct shareholders of portfolio securities are in many cases excepted from this reporting requirement, but, under current guidance, shareholders of a RIC are not excepted. This filing requirement applies even though, as a practical matter, any such loss would not, for example, reduce the taxable income of an insurance company. Future guidance may extend the current exception from this reporting requirement to shareholders
Qualifying Income described in clause (i) of subparagraph (a) above) will be treated as Qualifying Income. In general, such entities will be treated as partnerships for federal income tax purposes because they meet the passive income requirement under Code section 7704(c)(2). In addition, although in general the passive loss rules of the Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly traded partnership. Moreover, the amounts derived from investments in foreign currency will be treated as Qualifying Income for purposes of subparagraph (a) above. There is a remote possibility that the Internal Revenue Service (“IRS”) could issue guidance contrary to such treatment with respect to foreign currency gains that are not directly related to a RIC’s principal business of investing in stocks or securities (or options or futures with respect to stocks or securities), which could affect a Fund’s ability to meet the 90% gross income test and adversely affect the manner in which that Fund is managed.
The table below shows a performance example of a Short ProShares Fund that has an investment objective to correspond to the inverse (-1x) of the daily performance of an index. In the chart below, areas shaded lighter represent those scenarios where a Short ProShares Fund will return the same or outperform (i.e., return more than) the index performance; conversely, areas shaded darker represent those scenarios where a Short ProShares Fund will underperform (i.e., return less than) the index performance.
It is also possible that other digital currencies, typically referred to as “alt-coins”, and trading systems could become more widely accepted and used than Bitcoin. In particular, the digital asset “ethereum” has acquired a substantial share of the cryptocurrency market in recent months, which may be in part due to perceived institutional backing and/or potentially advantageous features not incorporated into bitcoin. There are other cryptocurrencies gaining momentum as the price of the bitcoin continues to rise and investors see the cheaper cryptocurrencies as attractive alternatives. The continued rise of these alt-coins can lead to a reduction in demand for bitcoin, which could have an adverse effect on the price of bitcoin and may have an adverse impact on the performance of Bitcoin Instruments and the performance of the Funds.
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.
Special Note Regarding the Correlation Risks of Geared Funds (All Funds, except the Matching ProShares Funds, 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 and the CDS Short North American HY Credit ETF)
For purposes of the diversification test described in subparagraph (b) above, the term “outstanding voting securities of such issuer” will include the equity securities of a qualified publicly traded partnership. Also, for purposes of the diversification test in (b) above, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In some cases, identification of the issuer (or issuers) is uncertain under current law, and an adverse determination or future guidance by the IRS with respect to issuer identification for a particular type of investment may adversely affect the Fund’s ability to meet the diversification test in (b) above.

Daniels Trading Now Offers Bitcoin Futures Trading - With values eclipsing $15,000 apiece, Bitcoin has seized the attention of the financial community and transformed many skeptics into enthusiastic participants. The surrounding buzz has given rise to deep cash markets and exceptional volatility — two characteristics especially attractive to traders and investors. In order to satisfy public demand for all things Bitcoin, the CME Group, Cboe, and Nasdaq decided to launch standardized Bitcoin derivatives.

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
The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[25] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[26] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[27]
Ann then goes on BFE and she wants to short on bitcoin at market price. She sees that only the January 9 contract has any orders. She could put a limit order in the orderbook if she wanted. However, she sees Bob's bid in the orderbook and decides to fill it, and uses her 0.2btc as margin to collateralize this position. She has just opened a position worth 1 bitcoin that has 5x leverage, and so has Bob.
You may wonder: where do these contracts come from? We know on the spot market that bitcoins are being bought and sold for fiat, but how the heck are bitcoins being used to trade bitcoin futures contracts? Let's walk through a really simple example showing how an exchange functions when there's just a simple two traders who want to go long and short. 
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
•   Daily Position Limit Risk - Many U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the trading day. In addition, these exchanges have established limits on the maximum amount of futures positions that any person may hold or control on such exchanges. These limits may restrict the amount of assets the Fund is able to invest in bitcoin futures contracts or have a negative impact on the price of such contracts. In order to comply with such limits, the Fund may be required to reduce the size of its outstanding positions or not enter into new positions that would otherwise be taken for the Fund. This could potentially subject the Funds to substantial losses or periods in which the Fund does not accept additional Creation Units.
The investment techniques and strategies discussed below may be used by a Fund if, in the opinion of the Advisor, the techniques or strategies may be advantageous to the Fund. A Fund may reduce or eliminate its use of any of these techniques or strategies without changing the Fund’s fundamental policies. There is no assurance that any of the techniques or strategies listed below, or any of the other methods of investment available to a Fund, will result in the achievement of the Fund’s objectives. Also, there can be no assurance that any Fund will grow to, or maintain, an economically viable size, and management may determine to liquidate a Fund at a time that may not be opportune for shareholders.
ProShare Advisors believes that its compensation program is competitively positioned to attract and retain high-caliber investment professionals. The compensation package for portfolio managers consists of a fixed base salary, an annual incentive bonus opportunity and a competitive benefits package. A portfolio manager’s salary compensation is designed to be competitive with the marketplace and reflect a portfolio manager’s relative experience and contribution to the firm. Fixed base salary compensation is reviewed and adjusted annually to reflect increases in the cost of living and market rates.

The Fund may invest in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.

The Trust has adopted a policy regarding the disclosure of information about each Fund’s portfolio holdings, which is reviewed on an annual basis. The Board of Trustees must approve all material amendments to this policy. A complete schedule of each Fund’s portfolio holdings as of the end of each fiscal quarter will be filed with the SEC (and publicly available) within 60 days of the end of the first and third fiscal quarters and within 70 days of the end of the second and fourth fiscal quarters. In addition, each Fund’s portfolio holdings will be publicly disseminated each day the Funds are open for business via the Funds’ website at
The Trust, the Advisor and the Distributor each have adopted a consolidated code of ethics (the “COE”), under Rule 17j-1 of the 1940 Act, which is reasonably designed to ensure that all acts, practices and courses of business engaged in by personnel of the Trust, the Advisor and the Distributor reflect high standards of conduct and comply with the requirements of the federal securities laws. There can be no assurance that the COE will be effective in preventing deceptive, manipulative or fraudulent activities. The COE permits personnel subject to it to invest in securities, including securities that may be held or purchased by a Fund; however, such transactions are reported on a regular basis. The Advisor’s personnel that are Access Persons, as the term is defined in the COE, subject to the COE are also required to report transactions in registered open-end investment companies advised or sub-advised by the Advisor. The COE is on file with the SEC and is available to the public.
When you display any broker’s profile page on the CME list above, you will see on the right hand side this broker’s specialties (a list of industries and/or financial products). As of this articles publication (Nov. 24, 2017), only one broker has added Bitcoin to his list of specialties: Level Trading Field LLC. However, this does not mean that the other brokers won’t handle Bitcoin futures. We expect that more of them will adopt this specialty as soon as Bitcoin futures are on the market.
