The Bitcoin protocol was built using open source software by a small group of individuals who developed what is known today as “Bitcoin Core.” 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” (as described herein). The Bitcoin Network has already experienced two major forks after developers attempted to increase transaction capacity. Blocks mined on these new “forked” networks now diverge from blocks mined on the original Bitcoin Network maintained by Bitcoin Core, resulting in the creation of two new blockchains whose digital assets are referred to as “bitcoin cash.” and “bitcoin gold.” Bitcoin, bitcoin cash and bitcoin gold now operate as separate, independent networks. Multiple BIPs still exist, many of which are aimed at increasing the transaction capacity of the Bitcoin Network, and it is possible that one or more of these BIPs could result in further network “forks.” Such changes may

•   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 ProShares 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.
Each Fund may invest directly in foreign currencies or hold financial instruments that provide exposure to foreign currencies, including “hard currencies,” or may invest in securities that trade in, or receive revenues in, foreign currencies. “Hard currencies” are currencies in which investors have confidence and are typically currencies of economically and politically stable industrialized nations. To the extent that a Fund invests in such currencies, that Fund will be subject to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time. Fund assets that are denominated in foreign currencies may be devalued against the U.S. dollar, resulting in a loss. Additionally, recent issues associated with the euro may have adverse effects on non-U.S. investments generally and on currency markets. A U.S. dollar investment in Depositary Receipts or ordinary shares of foreign issuers traded on U.S. exchanges may be affected differently by currency fluctuations than would an investment made in a foreign currency on a foreign exchange in shares of the same issuer. Foreign currencies are also subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government control.
More generally, investments by a Fund in options, futures, forward contracts, swaps and other derivative financial instruments are subject to numerous special and complex tax rules. These rules could affect whether gains and losses recognized by a Fund are treated as ordinary or capital, accelerate the recognition of income or gains to a Fund and defer or possibly prevent the recognition or use of certain losses by a Fund. The rules could, in turn, affect the amount, timing or character of the income distributed to shareholders by a Fund. In addition, because the tax rules applicable to such instruments may be uncertain under current law, an adverse determination or future IRS guidance with respect to these rules (which determination or guidance could be retroactive) may affect whether a Fund has made sufficient distributions and otherwise satisfied the relevant requirements to maintain its qualification as a RIC and avoid a Fund-level tax.
Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]
Furthermore, each Fund, except the Matching ProShares Funds, the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the CDS Short North American HY Credit ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, the Bitcoin Futures/Equity Strategy ETF has an investment objective to match the performance, a multiple (2x or 3x), the inverse (-1x) or a multiple of the inverse (-2x or -3x) of the performance of a benchmark on a single day. A “single day” is measured from the time the Fund calculates its NAV to the time of the Fund’s next NAV calculation. These Funds are subject to the correlation risks described above. In addition, while a close correlation of any Fund to its benchmark may be achieved on any single day, over time, the cumulative percentage increase or decrease in the NAV of the shares of a Fund may diverge, in some cases significantly, from the cumulative percentage decrease or increase in the benchmark due to a compounding effect as further described in the Prospectus and below.
Hey Will. Thanks for the helpful guide! I’ve just gotten into crypto and found this info extremely useful. Just a question regarding how you keep your alt coins safe. As far as I can tell, you can’t keep many of these alt coins on a Trezor hard wallet, so do you just use something like My Ether Wallet instead? Cheers mate! Here’s to a cracking 2018!!
Currently the front month future is the January contract which at last check could be sold for $17,600.  This contract settles in a cash transfer based on the 4:00 pm eastern bitcoin auction price on Wednesday January 17, 2018 established by Gemini who is partnering with Cboe Global Markets.  The bitcoin price at Gemini is close to $16,600 so I will use that for the underlying bitcoin price in this example. 
The Fund seeks inverse or “short” exposure through short positions in bitcoin futures contracts and other financial instruments. This will cause the Fund to be exposed to certain risks associated with selling securities short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of asset underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments such as swap agreements and futures contracts, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the asset underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by the assets underlying the Fund’s short positions will negatively impact the Fund.
The Funds may invest in bitcoin-based futures contracts, swap agreements, and options contracts, which are types of derivative contracts. A derivative refers to any financial instrument whose value is derived, at least in part, from the price of an underlying security, commodity, asset, rate, or index. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Changes in the value of a derivative may not correlate perfectly with the underlying security, asset, rate or index. Gains or losses in a derivative may be magnified and may be much greater than the derivative’s original cost. Because bitcoin-based derivatives were only recently introduced, the degree to which bitcoin-based derivatives are likely to provide exposure to movements in the price of bitcoin is extremely uncertain. If market participants executing trades in bitcoin-based derivatives face constraints, including capital constraints, security risks, or high execution costs with respect to direct investments in bitcoin, the price at which bitcoin-based derivatives trade may fail to capture price movements in the underlying price of bitcoin. Moreover, it is not clear how changes to the Bitcoin Network and determinations by any relevant derivatives exchange with respect to such changes to the Bitcoin Network will affect the value of any positions in bitcoin-based derivatives. [[In December 2015, the SEC proposed a new rule to regulate the use of derivatives by registered investment companies, such as the Fund. Whether and when this proposed rule will be adopted and its potential effects on the Fund are unclear as of the date of this Prospectus.]]
Distributions by a Fund to a shareholder that is not a “United States person” within the meaning of the Code (such a shareholder, a “foreign shareholder”) properly reported by the Fund as (1) Capital Gain Dividends, (2) short-term capital gain dividends, and (3) interest-related dividends, each as defined and subject to certain conditions described below, generally are not subject to withholding of U.S. federal income tax.
Poloniex is an asset exchange based in the US. Trading on Poloniex is secure and allows traders to explore new and trendy coins which are up for speculation. It offers high volume margin trading and lending service for major crypto assets. Reportedly, the largest user base for trading on this site comes from Russia (6.06%) and US (24.84%). A differentiating factor about the site is that it does not support fiat currency.
As of May 2018, over 1,800 cryptocurrency specifications existed.[29] Within a cryptocurrency system, the safety, integrity and balance of ledgers is maintained by a community of mutually distrustful parties referred to as miners: who use their computers to help validate and timestamp transactions, adding them to the ledger in accordance with a particular timestamping scheme.[16]
Oops! These guys seem to have had no background in cryptocurrency, which hurt them. If they had raised money from "donors" by selling tokens with no "rights, uses, purpose, attributes, functionalities or features," they'd be fine. But they were used to raising money from investors, so they called the people who bought their tokens "investors." It's a rookie crypto mistake, and one that might cost them all the money they raised.
Government regulation could adversely impact the operation of the Bitcoin Network or the use of bitcoin. As bitcoin and other digital assets have grown in popularity and in market size, certain U.S. federal and state governments, foreign governments and self-regulatory agencies have begun to examine the operations of bitcoin, digital assets, the Bitcoin Network, bitcoin users and related issues. Although currently bitcoin is not regulated or is lightly regulated in most countries, including the United States, some countries have, and one or more countries may in the future, take regulatory actions that severely restrict the right to acquire, own, hold, sell or use bitcoin or to exchange bitcoin for fiat currency. Regulation in the U.S. and foreign jurisdictions may restrict the use of bitcoin or otherwise materially impact the global demand for bitcoin. Regulation of initial coin offerings (“ICOs”) and other cryptocurrencies may have an impact the price of bitcoin. If Bitcoin Exchanges become subject to regulation, that may also impact trading in bitcoin as trading may be concentrated in a smaller number of regulated exchanges, which may impact price, volatility and trading volumes. Also, most Bitcoin Exchanges currently require bitcoin trading accounts to be fully funded, but if margin trading is introduced, there may be additional risks, including
•   Small-and Mid-Cap Company Investment Risk — The Fund may invest in stocks of small-and mid-cap companies. The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small-and mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Small-and mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Further, stocks of small-and mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies. In addition, small-and mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-and mid-cap security prices.
In May 2018 Bitcoin Gold (and two other cryptocurrencies) were hit by a successful 51% hashing attack by an unknown actor, in which exchanges lost estimated $18m.[90] In June 2018, Korean exchange Coinrail was hacked, losing US$37 million worth of altcoin. Fear surrounding the hack was blamed for a $42 billion cryptocurrency market selloff.[91] On 9 July 2018 the exchange Bancor had $23.5 million in cryptocurrency stolen.[92]
  •   Intellectual property rights claims may adversely affect the operation of the Bitcoin Network. Third parties may assert intellectual property rights claims relating to the operation of the Bitcoin Network. Regardless of the merit of any intellectual property or other legal action, any threatened action that reduces confidence in the Bitcoin Network’s long-term viability or the ability of end-users to hold and transfer bitcoin may adversely affect the price of bitcoin and adversely affect the price of the bitcoin futures contracts held by the Fund.
With the increased use of technologies such as the Internet and the dependence on computer systems to perform necessary business functions, each Fund is susceptible to operational and information security risks. In general, cyber incidents can result from deliberate attacks or unintentional events. Cyber attacks include, but are not limited to gaining unauthorized access to digital systems for purposes of misappropriating assets or sensitive information, corrupting data, or causing operational disruption. Cyber attacks may also be carried out in a manner that does not require gaining unauthorized access, such as causing denial-of-service attacks on websites. Cyber security failures or breaches of a Fund’s third -party service provider (including, but not limited to, index providers, the administrator and transfer agent) or the issuers of securities in which the Funds invest, have the ability to cause disruptions and impact business operations, potentially resulting in financial losses, the inability of Fund shareholders to transact business, violations of applicable privacy and other laws, regulatory fines, penalties, reputational damage, reimbursement or other compensation costs, and/or additional compliance costs. In addition, substantial costs may be incurred in order to prevent any cyber incidents in the future. The Funds and their shareholders could be negatively impacted as a result. While the Funds have established business continuity plans and systems to prevent such cyber attacks, there are inherent limitations in such plans and systems including the possibility that certain risks have not been identified. Furthermore, the Funds cannot control the cyber security plans and systems put in place by issuers in which the Funds invest.
As of September 16, 2017, the Trustees and officers of the Trust, as a group, owned outstanding shares that entitled them to give voting instructions with respect to less than one percent of the shares of any series of the Trust; except that Mr. Michael L. Sapir owned more than 25% of the outstanding shares of ProShares S&P 500 Ex-Financials ETF and ProShares S&P 500 Ex-Health Care ETF.
When you are getting started making actual trades, in general you should focus on making LIMIT ORDERS which will get FILLED by other traders. Not only will you pay lower fees this way, but you will also be making more composed trading setups because you aren't impatiently just market-buying or market-selling into the spread. So a general principle you should follow is to AVOID MARKET ORDERS WHEN YOU CAN! You will pay higher "taker" fees and you will be at the mercy of the spread which is a hidden fee.
Gains or losses attributable to fluctuations in exchange rates that occur between the time a Fund accrues income or other receivables or accrues expenses or other liabilities denominated in a foreign currency and the time the Fund actually collects such receivables or pays such liabilities generally are treated as ordinary income or ordinary loss. Similarly, on disposition of some investments, including debt securities and certain forward contracts denominated in a foreign currency, gains or losses attributable to
A distribution will be treated as paid on December 31 of a calendar year if it is declared by a Fund in October, November or December of that year with a record date in such a month and is paid by the Fund during January of the following year. Such distributions will be taxable to shareholders in the calendar year in which the distributions are declared, rather than the calendar year in which the distributions are received.
If, in any taxable year, a Fund were to fail to meet the 90% gross income, diversification or distribution test described above, the Fund could in some cases cure such failure, including by paying a Fund-level tax, paying interest, making additional distributions, or disposing of certain assets. If a Fund were ineligible to or did not cure such a failure for any taxable year, or otherwise failed to qualify as a RIC accorded special tax treatment under the Code, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including distributions of net tax-exempt income and net long-term capital gain (if any), would be taxable to shareholders as dividend income. In such a case, distributions from the Fund would not be deductible by the Fund in computing its taxable income. In addition, in order to requalify for taxation as a RIC, the Fund may be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
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.
Upon a sale, exchange or other disposition of shares of a Fund, a shareholder will generally realize a taxable gain or loss depending upon his or her basis in the shares. A gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands, and generally will be long-term or short-term capital gain or loss depending upon the shareholder’s holding period for the shares. Any loss realized on a sale, exchange or other disposition will be disallowed to the extent the shares disposed of are replaced (including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after the shares are disposed of. In such a case, the basis of the shares acquired will be adjusted to reflect the disallowed loss. Any loss realized by a shareholder on the disposition of a Fund’s Shares held by the shareholder for six months or less will be treated for tax purposes as a long-term capital loss to the extent of any distributions of Capital Gain Dividends received or treated as having been received by the shareholder with respect to such shares.

Basically, if you trade margin spot on a site like Kraken or Bitfinex, you will pay financing fees while you hold the position open. The same goes for CFD sites like WhaleClub or 1Broker. With bitcoin futures, you are able to trade margin without expending interest, because counterparties to the contract pay a fee to open and close the contract, and the exchange just manages the risk, so no money is really being lent!

Bitcoin futures are now available for trading on the Cboe Futures Exchange, LLC (CFE). CFE launched trading in Cboe bitcoin futures on December 10 under the ticker symbol "XBT" (contract specifications | fact sheet.) This brings many benefits to traders, including transparency, efficient price discovery, deep liquidity and centralized clearing. XBTSM futures provides a centralized marketplace for participants to trade based on their view of bitcoin prices, gain exposure to bitcoin prices or hedge their existing bitcoin positions.

U.S.-listed bitcoin futures contracts may aid institutional investor participation and enable hedging while also potentially helping digital assets develop into an asset class of their own. Currently digital assets trade on platforms that lack proper execution mechanisms, governance, and standard financial industry practices. Futures contracts push trading volume towards regulated exchanges with proper governance, controls and state of the art execution mechanisms. Futures contracts also remove the arduous requirement for investors to custody “physical” bitcoin, which is a major obstacle. In some ways, bitcoin futures are an early attempt to integrate digital assets into the mainframe financial system. With such integration, regulators might also gain a greater understanding of and steadier grasp on digital assets. This may enable the creation of more explicit guidance and regulation around the space. While it is early innings for digital assets, U.S.-listed bitcoin futures may pave the way for a potentially safer, more reliable, and better governed digital asset space and regulated investment vehicles.
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)
Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. In many of these instances, the customers of such Bitcoin Exchanges were not compensated or made whole for the partial or complete losses of their account balances in such Bitcoin Exchanges. No Bitcoin Exchange is immune from these risks but the existence of these risks has created a higher barrier of entry for new Bitcoin Exchanges. The loss of confidence in new and smaller Bitcoin Exchanges and in the Bitcoin Exchange Market overall can slow down the mass adoption of bitcoin. Further, the failure of the Bitcoin Exchange Market or any other major component of the overall bitcoin ecosystem can have consequences for the Bitcoin Network, have an adverse effect on the price of bitcoin and could have a negative impact on the Bitcoin Instruments in which certain of the Funds invest.
The Board has not adopted a policy of monitoring for frequent purchases and redemptions of shares that appear to attempt to take advantage of potential arbitrage opportunities. The Board believes this is appropriate because ETFs, such as the Funds, are intended to be attractive to arbitrageurs, as trading activity is critical to ensuring that the market price of Fund shares remains at or close to NAV.

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).
Trading directly on CME is not possible unless you are a broker yourself. This means that you have to pay a high fee – between thousands and hundreds of thousands of USD – to join CME. As an individual investor, you need to find a broker who trades on CME. You will then open an account with this broker – a margin account rather than a cash account because in options trading, there is a margin involved, as we have seen above. Because this poses a higher risk for the broker – in case you can’t settle your debts – these deals can only be done in special margin accounts and not cash accounts.
