In general, a beneficial owner of Fund Shares who or which is a foreign shareholder is not subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on a sale of shares of the Fund unless (i) such gain effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or and certain other conditions are met, or (iii) the special rules relating to gain attributable to the sale or exchange of “U.S. real property interests” (“USRPIs”) apply to the foreign shareholder’s sale of shares of the Fund (as described below).
Maintenance Margin - this is the % of the position value you have to have in your account at the very minimum to avoid being Margin Called.  In some exchanges, margin call will mean you get notified and must deposit more margin to avoid liquidation (like CryptoFacilities). On other exchanges you will at this point be liquidated out of your position. So if maintenance margin is 5%, then the 0.05 BTC of your initial margin will need to be kept for the position to be alive.

The legal status of cryptocurrencies varies substantially from country to country and is still undefined or changing in many of them. While some countries have explicitly allowed their use and trade,[66] others have banned or restricted it. According to the Library of Congress, an "absolute ban" on trading or using cryptocurrencies applies in eight countries: Algeria, Bolivia, Egypt, Iraq, Morocco, Nepal, Pakistan, and the United Arab Emirates. An "implicit ban" applies in another 15 countries, which include Bahrain, Bangladesh, China, Colombia, the Dominican Republic, Indonesia, Iran, Kuwait, Lesotho, Lithuania, Macau, Oman, Qatar, Saudi Arabia and Taiwan.[67] In the United States and Canada, state and provincial securities regulators, coordinated through the North American Securities Administrators Association, are investigating "bitcoin scams" and ICOs in 40 jurisdictions.[68]
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.
Most swap agreements entered into by a Fund (but generally not CDS) calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, a Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). Other swap agreements, such as CDS, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of the reference entity.
No Independent Trustee (or an immediate family member thereof) had any direct or indirect interest, the value of which exceeded $120,000, in the Advisor, the principal underwriter of the Trust, or any entity controlling, controlled by or under common control with the Advisor or the principal underwriter of the Trust (not including registered investment companies) during the two most recently completed calendar years.
By now you may ask yourself, “If I think that the price of an asset is going to rise, why should I buy a call option and not the asset itself?” The answer is this: Options give you leverage. That means that with a limited amount of capital, you can profit much more by buying options than assets – but also lose much more. This is because a small difference in the price of the underlying asset immediately leads to a substantial change in the price of the derivative. For example, when pork belly prices rise from 1,000 USD to 1,100 USD (an increase of 10%), call options for 1,000 USD suddenly become much more valuable – their prices may rise from 10.5 USD to 105 USD. Thus, if you have invested all of your capital in pork bellies, you will win 10% – if you have invested in pork belly call options, you will pocket a 1,000% profit.

  •   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.
I used to find it odd that these hypothetical AIs were supposed to be smart enough to solve problems that no human could, yet they were incapable of doing something most every adult has done: taking a step back and asking whether their current course of action is really a good idea. Then I realized that we are already surrounded by machines that demonstrate a complete lack of insight, we just call them corporations. Corporations don’t operate autonomously, of course, and the humans in charge of them are presumably capable of insight, but capitalism doesn’t reward them for using it. On the contrary, capitalism actively erodes this capacity in people by demanding that they replace their own judgment of what “good” means with “whatever the market decides.”
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.
Distributions of investment income are generally taxable to shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. In general, a Fund will recognize long-term capital gain or loss on investments it has owned for more than one year, and short-term capital gain or loss on investments it has owned for one year or less. Tax rules can alter a Fund’s holding period in investments and thereby affect the tax treatment of gain or loss on such investments. Distributions of net capital gain – the excess of net long-term capital gain over net short-term capital losses, in each case determined with reference to any loss carryforwards – that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable to shareholders as long-term capital gains includible in net capital gain and taxable to individuals at reduced rates. Distributions of net short-term capital gain (as reduced by any net long-term capital loss for the taxable year) will be taxable to shareholders as ordinary income.
The Officers, under the supervision of the Board, manage the day-to-day operations of the Trust. One Trustee and all of the Officers of the Trust are directors, officers or employees of ProShare Advisors or Foreside Management Services, LLC. The other Trustees are Independent Trustees. The Trustees and some Officers are also directors and officers of some or all of the other funds in the Fund Complex. The Fund Complex includes all funds advised by ProShare Advisors and any funds that have an investment adviser that is an affiliated person of ProShare Advisors.
Simply, the OBV is a remarkable technical indicator that can show us if the real money is really buying Bitcoin or quite the contrary they are selling. What we want to see when Bitcoin is failing to break above a resistance level or a swing high and the Ethereum already broke is for the OBV to not only increase in the direction of the trend, but to also move beyond the level it was when Bitcoin was trading previously at this resistance level (see figure below). Here is how to identify the right swing to boost your profit.
Each Fund, from time to time, in the ordinary course of business, may purchase securities on a when-issued or delayed-delivery basis (i.e., delivery and payment can take place between 30 and 120 days after the date of the transaction). These securities are subject to market fluctuations and no interest accrues to the purchaser during this period. At the time a Fund makes the commitment to purchase securities on a when-issued or delayed-delivery basis, the Fund will record the transaction and thereafter reflect the value of the securities, each day, in determining the Fund’s NAV. Each Fund will not purchase securities on a when-issued or delayed-delivery basis if, as a result, it determines that more than 15% of the Fund’s net assets would be invested in illiquid securities. At the time of delivery of the securities, the value of the securities may be more or less than the purchase price.

Bitcoin has been on a tear this year, surging at least 1,000 percent in 2017. As the cryptocurrency gained even more attention from investors recently, the Commodity Futures Trading Commission announced on Friday that it would allow the CME and Cboe to launch bitcoin futures. The Cboe plans to launch on Dec. 10 and the CME intends to launch on Dec. 18.

The equity markets are volatile, and the value of securities, swaps, futures, and other instruments correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks in the Index may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.
The regulation of bitcoin, digital assets and related products and services continues to evolve. The inconsistent and sometimes conflicting regulatory landscape may make it more difficult for bitcoin businesses to provide services, which may impede the growth of the bitcoin economy and have an adverse effect on consumer adoption of bitcoin. There is a possibility of future regulatory change altering, perhaps to a material extent, the nature of an investment in the Funds or the ability of the Funds to continue to operate. Additionally, to the extent that bitcoin itself is determined to be a security, commodity future or other regulated asset, or to the extent that a United States or foreign government or quasi-governmental agency exerts regulatory authority over the Bitcoin Network, bitcoin trading or ownership in bitcoin, the price of bitcoin and the value of the Bitcoin Instruments may be adversely affected, which may have an adverse effect on the value of your investment in the Funds. In sum, bitcoin regulation takes many different forms and will, therefore, impact bitcoin and its usage in a variety of manners. The European Union has recently agreed to rules designed to reduce anonymity of bitcoin transactions, which may impact the supply and demand for bitcoin and bitcoin futures contracts.
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. Such restrictions could have an adverse effect on the price of bitcoin and the Bitcoin Instruments in which the Funds invest and may adversely affect an investment in the Funds.
Market Spotlight – Bitcoin - A cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure transactions, control creation, and verify transactions. The first such cryptocurrency, Bitcoin, was introduced in 2009. In 2017, the exchanges launched a Bitcoin futures contract. The CBOE contract launched on Sunday, December 10, while the CME contract launched on Monday, December 18.
It will not, though: Everyone is exhausted, so P&G will just add Peltz to its board. This makes sense. The election is for all practical purposes a tie; the difference in votes appears to be well within the margin for measurement error. I think in that scenario a tie has to go to the activist: If 49.98 percent of your shareholders think something is going wrong, you might as well do something to appease them. 
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[89] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.

•   Rolling Futures Contract Risk — The Fund will invest in and have exposure to bitcoin futures contracts and is subject to risks related to “rolling” such contracts. Rolling occurs when the Fund closes out of a futures contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold futures contracts through expiration, but instead intends to “roll” its futures positions. When the market for these 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 contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher futures contract prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for 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 contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher futures prices for shorter expiration futures contracts is referred to as “backwardation.” Extended periods of contango could cause significant losses for the Fund. The Advisor will utilize active management techniques to seek to mitigate the negative impact or, in certain cases, benefit from the contango or backwardation present in the various futures contract markets, but there can be no guarantee that it will be successful in doing so.

The Bitcoin Network’s functionality relies on the Internet. A broadly accepted and widely adopted decentralized network is necessary for a fully-functional blockchain network, such as the Bitcoin Network. Features of the Bitcoin Network, such as decentralization, open source protocol, and reliance on peer-to-peer connectivity, are essential to preserve the stability of the network and decrease the risk of fraud or cyber-attacks. A significant disruption of Internet connectivity affecting large numbers of users or geographic areas could impede the functionality of the Bitcoin Network and adversely affect a Fund. In addition to technical disruptions such as cyber-attacks, the potential elimination of the net neutrality regulations in the U.S. may have a negative impact on miners, Bitcoin Markets and the Bitcoin ecosystem. Any technical disruptions or regulatory limitations that affect Internet access may have an adverse effect on the Bitcoin Network, the price of bitcoin and the Bitcoin Instruments in which the Funds invest.
The tables below show performance examples of an UltraPro and UltraPro Short ProShares Fund that have investment objectives to correspond to three times (3x) and three times the inverse (-3x) of, respectively, the daily performance of an index. In the charts below, areas shaded lighter represent those scenarios where a Fund will return the same as or outperform (i.e., return more than) the index performance times the stated multiple in the Fund’s investment objective; conversely, areas shaded darker represent those scenarios where the Fund will underperform (i.e., return less than) the index performance times the stated multiple in the Fund’s investment objective.

The global regulatory landscape for bitcoin and other digital assets has been inconsistent and continues to evolve. Some countries have taken an accommodating approach to the regulation of digital assets while others have banned their use. There are various accommodative approaches a country may take. Sweden and Australia treat bitcoin as a currency, while Canada and Taiwan have labeled bitcoin as a digital or virtual currency, distinct from fiat currency. Norway categorizes bitcoin as a form of virtual asset or commodity. The United Kingdom treats bitcoin as private money and determined that the value added tax will not apply to bitcoin sales, but it can be charged on the commission instead. In April 2017, legislation took effect in Japan that treats bitcoin and other digital assets as included in the definition of currency. In July 2016, the European Commission released a draft directive that proposed applying counter-terrorism and anti-money laundering regulations to virtual currencies, and, in September 2016, the European Banking authority advised the European Commission to institute new regulation specific to virtual currencies, with amendments to existing regulation as a stopgap measure. Regulatory bodies in some countries such as India and Switzerland have declined to exercise regulatory authority when afforded the opportunity.

These developments are expected to not only further rally the price of Bitcoin, but also open the doors for more traditional investment opportunities based on cryptocurrencies, such as a Bitcoin exchange-traded fund (ETF). ETFs are currently very popular investment products for beginning and advanced investors because they charge low fees and usually have low volatility. Because high volatility is one of the factors preventing conventional investors from entering the crypto market, products such as these could offer them the best of both worlds.
Each Fund may invest in money market instruments, which short-term cash instruments that have a remaining maturity of 397 days or less and exhibit high credit profiles, or cash or cash equivalents such as other high credit quality, short-term fixed income or similar securities, including (i) money market funds, (ii) U.S. Treasury Bills, which are U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government, and (iii) Repurchase Agreements, which are contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy them back at a specified time and price. Repurchase agreements are primarily used by the Funds as a short-term investment vehicle for cash positions.
Making money arbitraging bitcoin futures can be extremely simple. Futures contracts typically trade at a premium, and all you have to do, starting with USD, is buy bitcoin at Spot price and sell futures of the same amount at premium price. Then just wait until expiration to make your arb profit in bitcoin (which you can then put in USD). Whether it's a weekly, monthly, quarterly, or any futures contract, as long as it's in a premium, you lock in the sale price and earn the arbitrage profit.
