•   Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
Under a Rule 12b-1 Distribution Plan (the “Plan”) adopted by the Board, each Fund may pay its distributor and financial intermediaries, such as broker-dealers and investment advisors, up to 0.25% on an annualized basis of the average daily net assets of a Fund as reimbursement or compensation for distribution related activities with respect to the Funds. Because these fees are paid out of each Fund’s assets on an on-going basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. For the prior fiscal year, no payments were made by the fund under the Plan.
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.

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.
Changes in the laws of the United States and/or the Cayman Islands, under which the Parent Funds and the Subsidiaries are organized, respectively, could result in the inability of a Parent Fund and/or its respective Subsidiary to operate as described in this SAI and could negatively affect a Parent Fund and its shareholders. For example, the Cayman Islands does not currently impose any income, corporate or capital gains tax, estate duty, inheritance tax, gift tax or withholding tax on the Subsidiaries. If Cayman Islands law changes such that a Subsidiary must pay Cayman Islands taxes, Parent Fund shareholders would likely suffer decreased investment returns. See “Taxation” below for more information.
The existence of market makers (e.g., Virtu Financial) refutes a common assertion about futures—that there‘s always a loser for every winner, that it’s a zero-sum game. It’s true that derivatives like stock options and futures are created in matched pairs—a long and a short contract. If two speculators own those two contracts the profits on one side are offset by losses on the other but market makers are not speculators. In general, they’re not betting on the direction of the market. They act as intermediaries, selling to buyers at the higher ask price and buying from sellers at the lower bid price— collecting the difference.
Whether a Fund realizes a gain or loss from futures activities depends generally upon movements in the underlying currency, commodity, security or index. The extent of a Fund’s loss from an unhedged short position in futures contracts or from writing options on futures contracts is potentially unlimited, and investors may lose the amount that they invest plus any profits recognized on their investment. The Funds may engage in related closing transactions with respect to options on futures contracts. The Funds will engage in transactions in futures contracts and related options that are traded on a U.S. exchange or board of trade or that have been approved for sale in the U.S. by the Commodity Futures Trading Commission (“CFTC”).

On top of that, the cryptocurrency market travels at lightspeed compared to other markets. New coins enter the market on a daily basis (in 2016, there were about 550 different coins, today there are about 1,500), and each one has news every day. I’m not doubting your ability to consume and analyze news, but that level of information bombardment will always be more effectively consumed as a group. In these communities, you’ll see members link news and relevant articles about coins you’ve invested in and coins you’ve never heard of. The community will definitely expand your knowledge much faster than doing it all yourself.

If the Fund holds the foregoing kinds of securities, it may be required to pay out as an income distribution each year an amount which is greater than the total amount of cash interest the Fund actually received. Such distributions may be made from the cash assets of the Fund or, if necessary, by disposition of portfolio securities including at a time when it may not be advantageous to do so. These dispositions may cause the Fund to realize higher amounts of short-term capital gains (generally taxed to shareholders at ordinary income tax rates) and, in the event the Fund realizes net capital gains from such transactions, its shareholders may receive a larger Capital Gain Dividend than if the Fund had not held such securities.
Start small. Get familiar with the platform you're using before you make any significant trades. BitMEX offers a sandbox using Testnet coins. OKCoin and BitVC do not offer a demo version, but you can start small with 1 contract and test how Open Long, Open Short, Close Long, Close Short and different order types work. If you contact CryptoFacilities you can also get access to a demo platform to use.
If you are “going long” on Bitcoin, you assume that Bitcoin prices will go up. And if you expect Bitcoin prices to go up, you are interested in buying call options – options that enable you to buy Bitcoin at a predetermined price in the future. For example, if the current Bitcoin price is 5,000 USD and you expect it to rise to 8,000 USD 6 months from now, you would certainly pay good money for a call option that allows you to purchase Bitcoin for 5000 USD in 6 months, when everyone else is buying for 8,000 USD.
As we have seen above, a futures contract has an expiration date. This is the date on which you can purchase the ton of pork bellies for 1,000 USD – this is called a physical settlement. Alternatively, futures contracts can be settled with cash as well. In these contracts, you receive the difference between the current price of the underlying asset and the price in your contract as cash.
Distributions are taxable whether shareholders receive them in cash or reinvest them in additional shares. Distributions are also taxable to shareholders even if they are paid from income or gains earned by a Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for the Fund shares). Investors should be careful to consider the tax implications of buying shares of a Fund just prior to a distribution. The price of shares purchased at this time will include the amount of the forthcoming distribution, but the distribution will generally be taxable.
  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 introduction of futures didn't lead to a wave of hedge-fund money shorting bitcoin. It led to retail and institutional money going long bitcoin. We talked last week about the spread between Cboe's bitcoin futures price and the actual price of bitcoin, which was wider than $1,000 for a while. The spread has tightened considerably -- as of 8:15 a.m. today, the CME futures traded at $18,585, Cboe futures at $18,670, and spot bitcoin at about $18,245, for a spread of about 2 percent -- but it still exists. Why would you pay more for a synthetic bitcoin in a month than you would for an actual bitcoin today? The answer, presumably, is that the synthetic bitcoin is more valuable to you: You want bitcoin exposure, but you'd prefer to get it through a standardized contract on a regulated exchange that settles in dollars. 
Sections 1471-1474 of the Code and the U.S. Treasury and IRS guidance issued thereunder (collectively, “FATCA”) generally require a Fund to obtain information sufficient to identify the status of each of its shareholders under FATCA or under an applicable intergovernmental agreement (an “IGA”). If a shareholder fails to provide this information or otherwise fails to comply with FATCA or an IGA, a Fund or its agent may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on ordinary dividends it pays to such shareholder and 30% of the gross proceeds of share redemptions or exchanges and certain Capital Gain Dividends it pays to such shareholder after December 31, 2018. If a payment by a Fund is subject to FATCA withholding, the Fund or its agent is required to withhold even if such payment would otherwise be exempt from withholding under the rules applicable to foreign shareholders described above (e.g., Capital Gain Dividends, short-term capital gain dividends, and interest-related dividends).
Under an investment advisory agreement between ProShare Advisors and the Trust, on behalf of each Fund (the “Agreement” or “Advisory Agreement”), each Fund (other than the Morningstar Alternatives Solution ETF, the Global Listed Private Equity ETF, the Short Term USD Emerging Markets Bond ETF, the Inflation Expectations ETF and the CDS Short North American HY Credit ETF) pays ProShare Advisors a fee at an annualized rate, based on its average daily net assets, of 0.75%. ProShare Advisors has entered into an Advisory Fee Waiver Agreement for each of these Funds that reduces the annualized rate based on its average daily net assets, as follows: 0.75% of the first $4.0 billion of average daily net assets of the Fund; 0.70% of the average daily net assets of the Fund over $4.0 billion to $5.5 billion; 0.65% of the average daily net assets of the Fund over $5.5 billion to $7.0 billion; 0.60% of the average daily net assets of the Fund over $7.0 billion to $8.5 billion; and 0.55% of the average daily net assets of the Fund over $8.5 billion. The fee waiver arrangement will remain in effect through at least September 30, 2018 and prior to such date ProShare Advisors may not terminate the arrangement without the approval of the Board.
Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[110] and links it to Tulip mania.[111] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[112] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[113] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
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.

Cboe Futures Exchange, LLC (CFE) launched trading in Cboe bitcoin futures at 5:00 p.m. Central Time on December 10 under the ticker symbol "XBT". XBT℠ futures are cash-settled contracts based on the Gemini's auction price for bitcoin, denominated in U.S. dollars. Gemini Trust Company, LLC (Gemini) is a digital asset exchange and custodian founded in 2014 that allows customers to buy, sell, and store digital assets such as bitcoin, and is subject to fiduciary obligations, capital reserve requirements, and banking compliance standards of the New York State Department of Financial Services.3
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.
Transaction fees for cryptocurrency depend mainly on the supply of network capacity at the time, versus the demand from the currency holder for a faster transaction. The currency holder can choose a specific transaction fee, while network entities process transactions in order of highest offered fee to lowest. Cryptocurrency exchanges can simplify the process for currency holders by offering priority alternatives and thereby determine which fee will likely cause the transaction to be processed in the requested time.
Institutional-tier offerings such as those detailed above are seen as much-needed catalysts to stimulate the flow of institutional money into the market, offering heavyweight financial players a less-risky way to buy into assets like bitcoin. For the same reason, custody services like those offered by Coinbase, BitGo and others are necessary for safely storing and managing these investments as well.
Interestingly, the cryptocurrency market seems to rise and fall simultaneously with the altcoins. Is a systemic issue that causes this harmonious rise and fall of prices on the exchanges? The answer is a little fuzzy, but there are several factors at play. Most exchanges use Bitcoin as the universal trading currency, which leads to many investors buying and selling Bitcoin to buy and sell altcoins. When bitcoin starts a bull run, many of the altcoins fall, as investors jump on the Bitcoin train and vice versa. It’s also systemic because most exchanges require Bitcoin rather than fiat currency to transact. It is easy to invest fiat currency in the market and then leave there as an investor trades it; moving it from one currency to another and not cashing it back to fiat currency. Furthermore, When the Bitcoin price falls or rises against the fiat currency, all the altcoins will usually follow. This is because all altcoin prices are based on their Bitcoin exchange rate, not their fiat currency exchange rate. The value of an altcoin in fiat currency is the value of the altcoin in Bitcoin and then Bitcoin’s value in that fiat currency. It is Bitcoin that strongly affects pricing.
•   Valuation Risk — In certain circumstances, portfolio holdings may be valued using techniques other than market quotations. The value established for a portfolio holding may be different from what would be produced through the use of another methodology or if it had been priced using market quotations. Portfolio holdings that are valued using techniques other than market quotations, including “fair valued” securities, may be subject to greater fluctuation in their value from one day to the next than would be the case if market quotations were used. In addition, there is no assurance that the Fund could sell a portfolio holding for the value established for it at any time, and it is possible that the Fund would incur a loss because a portfolio holding is sold at a discount to its established value.
Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “Bitcoin Improvement Proposals”, or “BIPs.” If accepted by a sufficient number of miners, BIPs may result in substantial changes to the Bitcoin Network, including changes that result in “forks.” Such changes may influence
Moody’s ratings for state and municipal notes and other short-term loans are designated Moody’s Investment Grade (MIG) and for variable rate demand obligations are designated Variable Moody’s Investment Grade (VMIG). This distinction recognizes the differences between short-term credit risk and long-term risk. Loans bearing the designation MIG-1/VMIG-1 are of the best quality, enjoying strong protection from established cash flows of funds for their servicing or from established and broad-based access to the market for refinancing, or both. Loans bearing/with the designation MIG-2/VMIG-2 are of high quality, with ample margins of protection, although not as large as the preceding group.

In general, excess inclusion income allocated to shareholders (i) cannot be offset by net operating losses (subject to a limited exception for certain thrift institutions), (ii) will constitute unrelated business taxable income (“UBTI”) to entities (including a qualified pension plan, an individual retirement account, a 401(k) plan, a Keogh plan or other tax-exempt entity) subject to tax on UBTI, thereby potentially requiring such an entity that is allocated excess inclusion income, and otherwise might not be required to file a tax return, to file a return and pay tax on such income, and (iii) in the case of a foreign shareholder (defined below), will not qualify for any reduction in U.S. federal withholding tax. A shareholder will be subject to income tax on such inclusions without reference to any exemption therefrom otherwise available under the Code.
The primary risks associated with the use of futures contracts are imperfect correlation between movements in the price of the futures and the market value of the underlying assets, and the possibility of an illiquid market for a futures contract. Although each Fund intends to sell futures contracts only if there is an active market for such contracts, no assurance can be given that a liquid market will exist for any particular contract at any particular time. Many futures exchanges and boards of trade 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 day. Futures contract prices could move to the limit for several consecutive trading days with little or no trading, thereby preventing prompt liquidation of futures positions and potentially subjecting a Fund to substantial losses. If trading is not possible, or if a Fund determines not to close a futures position in anticipation of adverse price movements, the Fund will be required to make daily cash payments of variation margin. The risk that the Fund will be unable to close out a futures position will be minimized by entering into such transactions on a national exchange with an active and liquid secondary market. In addition, although the counterparty to a futures contract is often a clearing organization, backed by a group of financial institutions, there may be instances in which the counterparty could fail to perform its obligations, causing significant losses to a Fund.

•   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.


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.
