And this is where the BRR comes in. The BRR is the reference rate that is relevant for futures contracts and options in Bitcoin. When a futures contract or call option expires on a certain day, the owner will receive the difference between the BRR and the Bitcoin price in the contract as cash (if the BRR is higher than the price in the contract, of course). The BRTI, in contrast, is a real-time statistic that is not binding for any contracts; it tells you for what price you can currently (in this second) buy or sell Bitcoin on the markets.
A Precautionary Note Regarding Unusual Circumstances — ProShares Trust can postpone payment of redemption proceeds for any period during which (1) [the Exchange] is closed other than customary weekend and holiday closings, (2) trading on [the Exchange] is restricted, (3) any emergency circumstances exist, as determined by the SEC, and (4) the SEC by order permits for the protection of shareholders of the Fund, as further described in the SAI.
Nelson Peltz of Trian Fund Management waged a proxy fight to get himself on the board of Procter & Gamble Co. that ended at P&G's annual meeting in October, when Peltz lost out to management nominee Ernesto Zedillo by about 6.2 million votes. Or did he? In November, an independent recount of the votes found that Peltz had beaten Zedillo by 42,780 votes, or about 0.0016 percent of the shares outstanding. Or did he? On Friday the final official count of the votes came in, finding that Zedillo actually won by 498,312 votes, or about 0.019 percent of the shares outstanding. It is a little disappointing that Zedillo's margin in the third count, though less than his margin in the first count, was bigger than Peltz's margin in the second. I was hoping that not only would the victor alternate with each count, but also that the margin would get narrower and narrower, until eventually we'd find out that the two sides were exactly tied except for a single ballot for a single share written in a special ink that says "Peltz" under fluorescent light and "Zedillo" under natural light. I was hoping that P&G would count the votes again and again forever.
Investments in common units of MLPs involve risks that differ from investments in common stock. Holders of common units of MLPs have the rights typically provided to limited partners in limited partnerships and, thus, may have limited control and limited voting rights as compared to holders of a corporation’s common shares. Holders of common units may be subject to conflicts of interest with the MLP’s general partner, including those arising from incentive distribution payments. MLPs may also have limited financial resources and units may be subject to cash flow and dilution risk. In addition, investments held by MLPs may be relatively illiquid, limiting the MLPs’ ability to vary their portfolios promptly in response to changes in economic or other conditions. Accordingly, MLPs may be subject to more erratic price movements because of the underlying assets they hold. Further, a Fund’s investment in MLPs subjects the Fund to the risks associated with the specific industry or industries in which the MLPs invest.
Hi, unfortunately I bought bitcoin at the peak, then it fell all the way down before I switched over to some of the Altcoins you mentioned, however I didn’t realise the time I switched over to them, that the Altcoins were at a peak and when I switched they then fell down too leading to more of a loss. I also, feel a lot of those coins have maybe had their days of 100x, 10x their gains and had more potential at the time you bought into them.
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.
The promoters of these products promise traders a way to beat the market by arbitraging prices between different exchanges. Don’t believe the hype. Bitcoin exchanges often have expensive withdrawal processes and hefty fees for trading bitcoin with fiat currencies, such as dollars or euros. Also, settlement of bitcoin trades can take hours. These factors will eliminate any profits from bitcoin arbitrage and may even lead to losses.
Futures markets create an immense amount of flexibility. They enable investors to readily bet on an asset or bet against it (go long or go short), and they are usually characterised by an immense amount of leverage. In the case of bitcoin, this means one can trade a high volume of coins while only paying for a fraction of them, essentially operating with borrowed money. Leverage is used to amplify profits on a small volume of assets, but it is a double-edged sword in that it also amplifies losses.

For purposes of the diversification test described in subparagraph (b) above, the term “outstanding voting securities of such issuer” will include the equity securities of a qualified publicly traded partnership. Also, for purposes of the diversification test in (b) above, the identification of the issuer (or, in some cases, issuers) of a particular Fund investment can depend on the terms and conditions of that investment. In some cases, identification of the issuer (or issuers) is uncertain under current law, and an adverse determination or future guidance by the IRS with respect to issuer identification for a particular type of investment may adversely affect the Fund’s ability to meet the diversification test in (b) above.

Now there is an open interest in the futures contract created. The simple act of two traders with no open interest, one making a  limit order which then gets filled by the other, is what creates this position. The exchange then holds the 0.2 BTC margin of each party and the Profit and Loss (PNL) of the contract seesaws between counterparties based on market movements. If the exchange is liquid and rational, then the market price of the contract will change as the spot market moves. So if bitcoin price starts going up, futures traders will bid the price up.
That's why liquidity and volume are essential to a quality exchange. If you enter that contract at $400 and you see bitcoin spot price jumping to $500 but nobody is trading futures so you can't sell it to them, you get screwed. Luckily at this point in 2016 there are numerous options for trading futures that are liquid and settle on short time horizons. So you can typically trade contracts and get in and out of them with decent spreads and reasonable fees.
The Board of Trustees of the Trust reserves the right to declare a split or a consolidation in the number of Shares outstanding of any Fund, and may make a corresponding change in the number of Shares constituting a Creation Unit, in the event that the per Share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

The Trust is a Delaware statutory trust and registered investment company. The Trust was organized on May 29, 2002, and has authorized capital of unlimited Shares of beneficial interest of no par value which may be issued in more than one class or series. Currently, the Trust consists of multiple separately managed series. The Board of Trustees may designate additional series of beneficial interest and classify Shares of a particular series into one or more classes of that series.
•   Foreign Investments Risk — Investing in securities of foreign issuers may provide the Fund with increased risk. Various factors related to foreign investments may negatively impact the Fund’s performance, such as: i) fluctuations in the value of the applicable foreign currency; ii) differences in securities settlement practices; iii) uncertainty associated with evidence of ownership of investments in countries that lack centralized custodial services; iv) possible regulation of, or other limitations on, investments by U.S. investors in foreign investments; v) potentially higher brokerage commissions; vi) the possibility that a foreign government may withhold portions of interest and dividends at the source; vii) taxation of income earned in foreign countries or other foreign taxes imposed; viii) foreign exchange controls, which may include suspension of the ability to transfer currency from a foreign country; ix) less publicly available information about foreign issuers; x) changes in the denomination currency of a foreign investment; and xi) less certain legal systems in which the Fund might encounter difficulties or be unable to pursue legal remedies. Foreign investments also may be more susceptible to political, social, economic and regional factors than might be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined. Until the transactions are effected, the Fund is exposed to increased foreign currency risk and market risk.
JUNK BONDS. “Junk Bonds” generally offer a higher current yield than that available for higher-grade issues. However, lower-rated securities involve higher risks, in that they are especially subject to adverse changes in general economic conditions and in the industries in which the issuers are engaged, to changes in the financial condition of the issuers and to price fluctuations in response to changes in interest rates. During periods of economic downturn or rising interest rates, highly leveraged issuers may experience financial stress that could adversely affect their ability to make payments of interest and principal and increase the possibility of default. In addition, the market for lower-rated debt securities has expanded rapidly in recent years, and its growth paralleled a long economic expansion. At times in recent years, the prices of many lower-rated debt securities declined substantially, reflecting an expectation that many issuers of such securities might experience financial difficulties. As a result, the yields on lower-rated debt securities rose dramatically, but the higher yields did not reflect the value of the income stream that holders of such securities expected. Rather, the risk that holders of such securities could lose a substantial portion of their value as a result of the issuers’ financial restructuring or default. There can be no assurance that such declines will not recur. The market for lower-rated debt issues generally is thinner and less active than that for higher quality securities, which may limit each Fund’s ability to sell such securities at fair value in response to changes in the economy or financial markets. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may also decrease the values and liquidity of lower-rated securities, especially in a thinly traded market. Changes by recognized rating services in their rating of a fixed income security may affect the value of these investments. Each Fund will not necessarily dispose of a security when its rating is reduced below the rating it had at the time of purchase. However, the Advisor will monitor the investment to determine whether continued investment in the security will assist in meeting each Fund’s investment objective.
Bitcoin isn’t just an unknown commodity: it will always be an unknown commodity. Bitcoin doesn’t have the fundamentals that investors typically use to analyze an asset. Most stocks or bonds can be analyzed based on some trait of the instrument. Stocks have P/E ratios and dividends, for example, while bonds have return percentages. Bitcoin has no fundamentals that can be easily measured.

As a result of compounding, for periods greater than one day, the use of leverage tends to cause the performance of a Fund to vary from its benchmark performance times the stated multiple or inverse multiple in the Fund’s investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on geared funds. Four factors significantly affect how close daily compounded returns are to longer-term benchmark returns times the fund’s multiple: the length of the holding period, benchmark volatility, whether the multiple is positive or inverse, and its leverage level. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each can lead to returns farther from the multiple times the benchmark return. As the tables below show, particularly during periods of higher benchmark volatility, compounding will cause longer term results to vary from the benchmark performance times the stated multiple in the Fund’s investment objective. This effect becomes more pronounced as volatility increases.

•   Compounding Risk — In the course of managing the Fund’s investments, ProShare Advisors will need to periodically adjust the Fund’s holdings in order to maintain investment exposure approximately equivalent to the Fund’s assets. This process entails obtaining additional inverse exposure as the Fund experiences gains, and reducing inverse exposure as the Fund experiences losses. The higher the volatility of the bitcoin futures contracts in which the Fund invests, the more such rebalancing can adversely affect the Fund’s performance.
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.
