The most common way to trade in Bitcoin and other cryptocurrency derivatives today is through contract-for-difference (CFD) contracts. These CFD contracts are usually traded over the counter (OTC), meaning that they are not traded on exchanges but directly between participants. Due to the high volatility (exceeding 1.5-2x std from the mean) most of the OTC platforms do not provide leverage on bitcoin and other cryptos CFDs.
It is expected that each Subsidiary will neither be subject to taxation on its net income in the same manner as a corporation formed in the United States nor subject to branch profits tax on the income and gain derived from its activities in the United States. A foreign corporation will generally not be subject to such taxation unless it is engaged in or is treated as engaged in a U.S. trade or business. Each Subsidiary expects to operate in a manner such that it is not so engaged or so treated.
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. 
The Funds may invest in the securities of other investment companies, including exchange-traded funds (ETFs) and unit investment trusts (UITs), to the extent that such an investment would be consistent with the requirements of the 1940 Act or any exemptive order issued by the SEC. If a Fund invests in, and thus, is a shareholder of, another investment company, the Fund’s shareholders will indirectly bear the Fund’s proportionate share of the fees and expenses paid by such other investment company, including advisory fees, in addition to both the management fees payable directly by the Fund to the Fund’s own investment adviser and the other expenses that the Fund bears directly in connection with the Fund’s own operations.
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.

Investments by a Fund in a wholly-owned foreign subsidiary, debt obligations issued or purchased at a discount and certain derivative instruments could cause the Fund to recognize taxable income in excess of the cash generated by such investments, potentially requiring the Fund to dispose of investments (including when otherwise disadvantageous to do so) in order to meet

A Parent Fund’s recognition of any subpart F income from an investment in its Subsidiary will increase the Fund’s tax basis in such subsidiary. Distributions by a Subsidiary to a Parent Fund, including in redemption of its Subsidiary’s shares, will be tax free, to the extent of its Subsidiary’s previously undistributed subpart F income, and will correspondingly reduce the Fund’s tax basis in its Subsidiary, and any distributions in excess of the Fund’s tax basis in its Subsidiary will be treated as realized gain. Any losses with respect to the Fund’s shares of its Subsidiary will not be currently recognized. Subpart F income is generally treated as ordinary income, regardless of the character of a Subsidiary’s underlying income.

Accordingly, the Advisor is subject to registration and regulation as a CPO under the CEA, and must comply with various regulatory requirements under the CEA and the rules and regulations of the CFTC and the National Futures Association (“NFA”), including investor protection requirements, antifraud provisions, disclosure requirements and reporting and recordkeeping requirements. The Advisor is also subject to periodic inspections and audits by the CFTC and NFA. Compliance with these regulatory requirements could adversely affect the Commodity Pools’ total return. In this regard, any further amendment to the CEA or its related regulations that subject the Advisor or the Commodity Pools to additional regulation may have adverse impacts on the Commodity Pools’ operations and expenses.
​The price of the futures contract can deviate from the underlying price of bitcoin on spot markets, which can vary based on sentiment. But in the end, at expiration of the contract, the contract MUST settle at the price of spot. So you need to watch the main spot market price movements because the futures contracts will track the movements underlying (sometimes leading, sometimes lagging, sometimes simultaneously). There are three Chinese exchanges worth following: OKCoin, Houbi, and BTCC; there are two Western exchanges worth following: Bitfinex and Bitstamp. Other exchanges that are currently less important but still worth keeping an eye on are: ItBit, Coinbase, OKCoin USD, BTC-e, and Kraken (which has the largest BTC/EUR orderbook as of December 2015).
•   Dividends paid to a shareholder that is not a “United States person” within the meaning of the Code (such a shareholder, a “foreign person”) that a Fund properly reports as capital gain dividends, short-term capital gain dividends or interest -related dividends, each as further defined in the SAI, are not subject to withholding of U.S. federal income tax, provided that certain other requirements are met. A Fund (or intermediary, as applicable) is permitted, but is not required, to report any part of its dividends as are eligible for such treatment. A Fund’s dividends other than those the Fund properly reports as capital gain dividends, short-term capital gain dividends or interest-related dividends generally will be subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate). Special tax considerations may apply to foreign persons investing in the Fund. Please see the SAI for more information.

EDIT: #10 Bonus (Suggested by @kerstenwirth ) — always check the ticker symbol. Ticker symbols are not universal, and may vary from exchange to exchange in rare cases. Those cases, though, can come back to bite you. For example, Bitcoin Cash trades on some exchanges as BCH, while it trades on others as BCC. BCC is also the ticker symbol for BitConnect, which was recently outted as a Ponzi Scheme. If you bought BCC under the impression was Bitcoin Cash, you would’ve lost a lot of money.
Last night, Cboe XBTSM Bitcoin Futures commenced trading on the Cboe Futures Exchange.  The launch was smooth, although our website experienced some issues due to an overwhelming number of hits looking for the trading data.  Now that the futures are up and running, it may be time for a brief explanation of how an owner of bitcoins may use futures to hedge their position. 
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.
Yes but ... in cryptocurrencies? If you had borrowed 100 bitcoins to finance your working capital needs a year ago, you'd have financed about $79,000 worth of working capital. If you had to pay back 112 bitcoins today, that would come to a bit over $2 million, a dollar interest rate of over 2,400 percent. (If you'd borrowed ether you'd be paying over 12,000 percent.) Unless your working capital was bitcoin, you will not be able to pay back that loan. The lesson here is: Probably don't borrow an asset caught in a massive speculative frenzy to fund your working capital needs.

Bitcoin has a very limited history of operations and there is no established performance record for the price of Bitcoin on the Bitcoin Exchange Market that can provide an adequate basis for evaluating an investment in bitcoin or Bitcoin Instruments such as Bitcoin Derivatives, ETNs and Bitcoin Securities. Although past performance is not necessarily indicative of future results, if bitcoin had an established history, such history might (or might not) provide investors with more information on which to evaluate an investment in the Funds.
The Fund generally does not expect to invest directly in futures contracts, option contracts and swap agreements (“Bitcoin Instruments”). The Fund expects to gain exposure to these investments by investing a portion of its assets in the ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio, a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by ProShare Advisors, the Fund’s investment advisor, and invests directly in Bitcoin Instruments. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Fund’s investment in the Subsidiary is intended to provide the Fund with exposure to commodity markets related to bitcoin in accordance with applicable rules and regulations. The Fund will invest up to 25% of its total assets in the Subsidiary. Except as otherwise noted, references to the Fund’s investment strategies and risks include the investment strategies and risks of the Subsidiary.
There are two "types" of bitcoin -- Quanto and Inverse. Vast majority of bitcoin futures contracts are INVERSE, not Quanto. This means that the PNL is smoothed in USD terms, so that the contract value is maintained through price fluctuations. Put simply, it allows you to make a perfect USD-value hedge when you short with Bitcoin, which makes it ideal for speculators and hedgers. This means that if the BTC/USD value drops 1% you will earn more raw BTC than if it increases 1%. This is because when the price is falling, the USD value of the BTC is also falling, so the payout mathematically adjusts for this and increases as the price falls, compensating for the reduced USD value.
In addition, the securities of some foreign governments, companies and markets are less liquid, and may be more volatile, than comparable securities of domestic governments, companies and markets. Some foreign investments may be subject to brokerage commissions and fees that are higher than those applicable to U.S. investments. A Fund also may be affected by different settlement practices or delayed settlements in some foreign markets. Moreover, some foreign jurisdictions regulate and limit U.S. investments in the securities of certain issuers.
The NAV per share of each Fund is computed by dividing the value of the net assets of such Fund (i.e., the value of its total assets less total liabilities) by its total number of Fund shares outstanding. Expenses and fees are accrued daily and taken into account for purposes of determining NAV. The NAV of each Fund is calculated by JPMorgan Chase Bank, National Association. The NAV of each Fund is generally determined each business day at the close of regular trading of the                    (ordinarily 3:00 p.m. Eastern time). The Fund’s investments are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. In addition, routine valuation of certain other derivatives is performed using procedures approved by the Board.
In September 2015, the establishment of the peer-reviewed academic journal Ledger (ISSN 2379-5980) was announced. It covers studies of cryptocurrencies and related technologies, and is published by the University of Pittsburgh.[114][115] The journal encourages authors to digitally sign a file hash of submitted papers, which will then be timestamped into the bitcoin blockchain. Authors are also asked to include a personal bitcoin address in the first page of their papers.[116][117]
The Fund pays transaction costs, such as commissions, when it buys and sells securities (including through the Subsidiary, as defined below), or “turns over” its portfolio. A higher portfolio turnover rate for the Fund or the Subsidiary may indicate higher transaction costs and may result in higher taxes when the Fund’s shares are held in a taxable account. These costs, which are not reflected in Annual Fund Operating Expenses or in the example above, affect the Fund’s performance. The Fund has not yet commenced operations as of the date of this Prospectus. Thus, no portfolio turnover information is provided for this Fund.
For example, you can enter a Bitcoin futures contract with Mortimer Duke saying that you will sell him 1 BTC on March 30, 2018, for the price of 5,000 USD per BTC. (In the actual CME futures contracts, the limit for one contract is 5 BTC, but we will stick with 1 BTC now for the purposes of easy explanation.) You enter into this contract on an exchange like CME.
