•   If a Fund qualifies for treatment as a regulated investment company, it is not subject to federal income tax on net investment income and net realized capital gains that the Fund timely distributes to its shareholders. If a Fund were to fail to so qualify, and were ineligible to or otherwise did not cure such failure, its taxable income and gains would be subject to tax at the Fund level, and distributions from earnings and profits would be taxable to shareholders as ordinary income.
In addition, the Advisor, its affiliates and principals may trade for their own accounts. Consequently, non-customer and proprietary trades may be executed and cleared through any prime broker or other broker utilized by clients. It is possible that officers or employees of the Advisor may buy or sell securities or other instruments that the Advisor has recommended to, or purchased for, its clients and may engage in transactions for their own accounts in a manner that is inconsistent with the Advisor’s recommendations to a client. Personal securities transactions by employees may raise potential conflicts of interest when such persons trade in a security that is owned by, or considered for purchase or sale for, a client. The Advisor has adopted policies and procedures designed to detect and prevent such conflicts of interest and, when they do arise, to ensure that it effects transactions for clients in a manner that is consistent with its fiduciary duty to its clients and in accordance with applicable law.
Recent bitcoin futures contract announcements from CBOE, CME, and Nasdaq have generated tremendous interest in digital assets. Bitcoin futures have been highly anticipated as they will provide traditional financial institutions with one of the first opportunities to meaningfully participate in the digital asset space via a regulated investment framework. It is an opportunity for Wall Street to catch up with Main Street on bitcoin. With the impending launch of U.S.-listed bitcoin futures, investors may wonder what the bitcoin futures curve might look like. Using information from existing digital asset derivative trading platforms such as Bitmex, OKCoin, CryptoFacilities, and BTCC (all exchanges outside of the Commodity Futures Trading Commission purview), MVIS Research has constructed an approximate curve based on non-U.S. bitcoin futures trading on these exchanges. These are real trading platforms revealing real volume.
•   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.
Futures trading is not suitable for all investors and involves the risk of loss. The risk of loss in futures can be substantial. You should, therefore, carefully consider whether such trading is suitable for you in light of your circumstances and financial resources. For additional information regarding futures trading risks, see the Risk Disclosure Statement set forth in CFTC Regulation §1.55(b). The information on this website is provided solely for general education and information purposes and therefore should not be considered complete, precise, or current.

R-1 (middle) – Short term debt rated “R-1 (middle)” is of superior credit quality and, in most cases, ratings in this category differ from “R-1 (high)” credits to only a small degree. Given the extremely tough definition which DBRS has for the “R-1 (high)” category (which few companies are able to achieve), entities rated “R-1 (middle)” are also considered strong credits which typically exemplify above average strength in key areas of consideration for debt protection.
Many expect bitcoin futures to stabilise the markets because big institutional investors will be able to trade bitcoin using all the flexibility present in sophisticated trading markets, with effective risk management and hedging strategies. Since the CME plans to set price limits on the trading range of bitcoin futures, the price of the coin is expected to become more stable. That is the optimistic outlook. It is reasonable to assume that if futures markets will indeed take off the way they are expected to, the market will eventually gravitate towards a less volatile state.
Knowing their estimated costs and profit requirements the arbitrageur determines a minimum difference they need between the futures’ prices and the spot price before they will enter the market. They then monitor the price difference between Bitcoin futures and the Bitcoin exchanges and if large enough they act to profit on that gap.  For example, if a specific Bitcoin future (e.g., February contract) is trading sufficiently higher than the current Bitcoin exchange price they will short that Bitcoin future and hedge their position by buying Bitcoins on the exchange. At that point, if they have achieved trade prices within their targets, they have locked in a guaranteed profit. They will hold those positions until contract expiration (or until they can cover their short futures and sell Bitcoins at a profit).
XBT futures is a cash-settled contract that settles to a single, tradeable auction price. In designing XBT futures, Cboe leveraged its significant product development expertise to design an instrument that allows participants to implement trading strategies in a manner to which they are accustomed. The single price settlement process gives participants the option of using XBT futures to hedge their exposure in underlying bitcoin or gain exposure to traded bitcoin prices without holding bitcoin.
•   Investments by a Fund in options, futures, forward contracts, swap agreements and other derivative financial instruments are subject to numerous special and complex tax rules. These rules could affect the amount, timing or character of the distributions to shareholders by a Fund. In addition, because the application of these rules may be uncertain under current law, an adverse determination or future Internal Revenue Service guidance with respect to these rules may affect whether a Fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid fund-level tax.

Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of a Fund could be required to report annually their “financial interest” in the Fund’s “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in a Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.

•   Subsidiary Investment Risk — Changes in the laws of the United States and/or the Cayman Islands, under which the Fund and the Subsidiary are organized, respectively, could result in the inability of the Fund to operate as intended and could negatively affect the Fund and its shareholders. The Subsidiary is not registered under the 1940 Act and is not subject to all the investor protections of the 1940 Act. Thus, the Fund, as an investor in the Subsidiary, will not have all the protections offered to investors in registered investment companies.

cooperatives) is a record holder of a Share in a Fund that recognizes “excess inclusion income,” then the Fund will be subject to a tax on that portion of its “excess inclusion income” for the taxable year that is allocable to such shareholders at the highest federal corporate income tax rate. The extent to which this IRS guidance remains applicable in light of the December 2006 legislation is unclear. To the extent permitted under the 1940 Act, each Fund may elect to specially allocate any such tax to the applicable CRT, or other shareholder, and thus reduce such shareholder’s distributions for the year by the amount of the tax that relates to such shareholder’s interest in the Fund. The Funds have not yet determined whether such an election will be made.

The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in a combination of short positions in bitcoin futures contracts and money market instruments. The Fund is designed to benefit when the price of bitcoin futures contracts declines. The Fund generally seeks to have 30% of the value of its portfolio invested in short positions in bitcoin futures contracts and 70% of the value of its portfolio invested in money market instruments.
In order to make sure that you actually have money in your margin account to settle the difference with Mortimer every day, you are required to put up an initial margin at the beginning of the contract. A lower sum, the so-called minimum margin or maintenance margin, is also defined by the broker. If the money in your margin account falls from the initial margin to the maintenance margin, it triggers a margin call: The broker requests you to fill up your margin account to at least the initial margin (of course, you may also put up more).
Any distribution of income that is attributable to (i) income received by a Fund in lieu of dividends with respect to securities on loan pursuant to a securities lending transaction or (ii) dividend income received by a Fund on securities it temporarily purchased from a counterparty pursuant to a repurchase agreement that is treated for U.S. federal income tax purposes as a loan by the Fund, will not constitute qualified dividend income to individual shareholders and will not be eligible for the dividends-received deduction for corporate shareholders.

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.

In a futures market, if the price is $500/BTC, an investor needs to buy 50 futures contracts, each worth $10. If an investor wishes to open a positive position then he goes long with “buy" contracts, and if he decides to open a negative position, he goes short with “sell” contracts. An investor’s position can be either positive or negative for the same instrument. (For more, see: Bitcoin Mass Hysteria: The Disaster that Brought Down Mt. Gox.)
Localbitcoins is the portal that exchanges trades between person to person where you interact with the seller directly. On this platform, people from different countries can exchange their local currency to bitcoins. The site is suggested for casual traders seeking more privacy. The site uses an escrow system and the transfer of bitcoin is made after funds are received in the sellers account. Registering, buying and selling is completely free on localbitcoins while local bitcoin users who create advertisements charges 1% fee for every completed trade.
The Advisor and its affiliated persons may come into possession from time to time of material nonpublic and other confidential information about companies which, if disclosed, might affect an investor’s decision to buy, sell, or hold a security. Under applicable law, the Advisor and its affiliated persons would be prohibited from improperly disclosing or using this information for their personal benefit or for the benefit of any person, regardless of whether the person is a client of the Advisor. Accordingly, should the Advisor or any affiliated person come into possession of material nonpublic or other confidential information with respect to any company, the Advisor and its affiliated persons will have no responsibility or liability for failing to disclose the information to clients as a result of following its policies and procedures designed to comply with applicable law. However, each Matching Fund is managed using what is commonly referred to as an index strategy in an attempt to simulate either the daily movement or a multiple, the inverse or an inverse multiple of the daily movement of its index, and the use of such index strategies may reduce conflicts of interest compared to funds using non-index investment strategies.
  •   Intellectual property claims. A proliferation of recent startups attempting to apply blockchain technology in different contexts means the possibility of conflicting intellectual property claims could be a risk to an issuer, its operations or its business. This could also pose a risk to blockchain platforms that permit transactions in digital securities.
Mathematically, to regain a 50% loss you need the price to rise 100% (double) so don’t let yourself get there. Psychologically, you force yourself to trade to make up for the losses, and under pressure, you won’t make the best decisions. Cut losses early and re-evaluate your reasons for the trade, go back in later on, at a lower price if needed. Don’t take profits early, wait for a drop – this is a good enough place to close the trade

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.

Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. Businesses are starting to accept bitcoin as payment, either directly or, more commonly, through an intermediary service which converts bitcoin payments into local currency. The adoption of bitcoin as a means of payment, however, has been limited when compared with the increase in the price of bitcoin as determined by the Bitcoin Exchange Market, indicating that the majority of bitcoin’s use is for investment and speculative purposes. The continued adoption of bitcoin will require growth in its usage as a means of payment and in the Bitcoin Blockchain for various applications.
•   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.
Amounts not distributed on a timely basis in accordance with a prescribed formula are subject to a nondeductible 4% excise tax at the Fund level. To avoid the tax, each Fund must distribute during each calendar year an amount generally equal to the sum of (1) at least 98% of its ordinary income (not taking into account any capital gains or losses) for the calendar year, (2) at least 98.2% of its capital gains in excess of its capital losses (adjusted for certain ordinary losses) for a one-year period generally ending on October 31
When a market price is not readily available, each Fund’s investments are valued at fair value in good faith under procedures established by, and under the general supervision and responsibility of, the Board. The use of a fair valuation method may be appropriate if, for example: (i) market quotations do not accurately reflect fair value of an investment; (ii) an investment’s value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded; (iii) a trading halt closes an exchange or market early; or (iv) other events result in an exchange or market delaying its normal close. This procedure incurs the unavoidable risk that the valuation may be higher or lower than the securities might actually command if the Funds sold them. See the SAI for more details.
Under normal market conditions, each Fund intends to invest substantially all of its assets in Benchmark Futures Contracts. The contractual obligations of a buyer or seller holding a futures contract to expiration may be satisfied by settling in cash as designated in the contract specifications. Alternatively, futures contracts may be closed out prior to expiration by making an offsetting sale or purchase of an identical futures contract on the same or linked exchange before the designated date of settlement. Once this date is reached, the futures contract “expires.” The Funds do not intend to hold bitcoin futures contracts through expiration, but instead to “roll” their respective positions. “Rolling” refers to a process whereby futures contracts nearing expiration are closed out and replaced with an identical futures contract with a later expiration date. Accordingly, the Funds are subjects to risks related to rolling.
BitMEX also has a weekly rebalancing for all their contracts, but currently their most popular product is the Daily 100x maximum leverage contract. This settles daily, but otherwise the rest of the contracts are handled on Friday, a little bit after OKCoin's 8:00AM UTC. See this website to get a countdown to the settlements on the different exchanges. The policies of exchanges are changing often so this information may be outdated by the time you read it (though we will try to keep it as up to date as possible).

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.
Because of the wide range of types and maturities of corporate debt securities, as well as the range of creditworthiness of its issuers, corporate debt securities have widely varying potentials for return and risk profiles. For example, commercial paper issued by a large established domestic corporation that is rated investment-grade may have a modest return on principal, but carries relatively limited risk. On the other hand, a long-term corporate note issued by a small foreign corporation from an emerging market country that has not been rated may have the potential for relatively large returns on principal, but carries a relatively high degree of risk.

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.
There are two USA regulated Bitcoin futures exchanges in operation. The CME’s contract unit is five Bitcoins whereas the Cboe’s contract unit is one—that’s the biggest difference between these futures. The upfront money to buy or sell short a CME contract will be about five times higher than the Cboe contract. Larger investors won’t care but this will be an issue for smaller investors. Another difference is the spot/settlement process that the exchanges use. In the case of Cboe futures, the contracts will be settled to a 4 pm ET Gemini exchange auction price on the day of expiration, for the CME futures the settlement price is a complex calculation using an hour of volume weighted data from multiple exchanges (currently Bitstamp, itBit, Kraken, and GDAX). With the CME’s approach, it will be harder to manipulate the settlement price but it doesn’t give arbitrageurs a physical mechanism to trade their positions—possibly an issue.
