Example: If the futures contract price is $400, then you can buy 0.5btc worth of this and if the price of bitcoin goes up to $450 the futures contract price will go up, and the value increases from 0.5 BTC and you can just sell for a profit. Trading a synthetic derivative rather than spot bitcoin allows you to use margin leverage to more easily buy and sell -- the contracts are just a facilitation of the value.

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

The Index Receipt Agent makes available through the NSCC on each Business Day, either immediately prior to the opening of business on the Exchange or the night before, the list of the names and the required number of shares of each Deposit Security to be included in the current Portfolio Deposit (based on information at the end of the previous Business Day) for each applicable Fund. Such Portfolio Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of Shares of such Fund until the next-announced Portfolio Deposit composition is made available.

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 Distribution and Service Plan is intended to permit the financing of a broad array of distribution-related activities and services, as well as shareholder services, for the benefit of investors. These activities and services are intended to make the Shares an attractive investment alternative, which may lead to increased assets, increased investment opportunities and diversification, and reduced per share operating expenses. There are currently no plans to impose distribution fees.
 	•	 	ADRs represent the right to receive securities of foreign issuers deposited in a bank or trust company. ADRs are an alternative to purchasing the underlying securities in their national markets and currencies. Investment in ADRs has certain advantages over direct investment in the underlying foreign securities because: (i) ADRs are U.S. dollardenominated investments that are easily transferable and for which market quotations are readily available; and (ii) issuers whose securities are represented by ADRs are generally subject to auditing, accounting and financial reporting standards similar to those applied to domestic issuers.

"We expect that the futures exchanges, through information sharing agreements, will be monitoring the trading activity on the relevant cash platforms for potential impacts on the futures contracts' price discovery process," CFTC Chair J. Christopher Giancarlo said in an official statement. "This includes potential market manipulation and market dislocations due to flash rallies and crashes and trading outages."
The Bitcoin Network is currently maintained by Bitcoin Core and no single entity owns the Bitcoin Network (see “Description of Bitcoin and the Bitcoin Network—The Bitcoin Network”). However, third parties may still 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 Bitcoin Instruments. Additionally, a meritorious intellectual property rights claim could prevent end-users from accessing the Bitcoin Network or holding or transferring their bitcoin, which could adversely affect the value of the Bitcoin Instruments. As a result, an intellectual property rights claim against Bitcoin Network participants could have a material adverse impact on the Funds.
These days, all of the BTC/USD contracts trading at active futures markets are inverse, as mentioned in the beginning of this guide. The only differences between the exchanges is how they trigger liquidations and the procedure for handling margin calls. They all use Bitcoin as the currency, of course, and you can use the table below for a basic feature comparison:
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.
I under-performed the market in 2017. A crypto market that went up several hundred percent and having read 24 books on finance and trading throughout the process, these were my biggest takeaways. Remember, these are notes I wrote to myself, so they may not work for your trading style. This version was summarized exclusively for CryptoMarket360 – a full version is hyperlinked at the bottom.

The information in this Prospectus is not complete and may be changed. Shares of the Funds may not be sold until the registration statement filed with the Securities and Exchange Commission is effective. This Prospectus is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

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.
Individual shares of the Fund will be listed for trading on [the Exchange] and can be bought and sold in the secondary market at market prices. The market price of shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares, and other market factors. ProShare Advisors cannot predict whether the Fund’s shares will trade above, below or at a price equal to the value of the Fund’s holdings. Differences between secondary market prices and NAV, the value of the Fund’s holdings, may be due largely to supply and demand forces in the secondary market, which may not be the same forces as those influencing prices for securities or financial instruments held by the Fund at a particular time. Given the fact that the Fund’s shares can be created and redeemed in Creation Units, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained.

When you display any broker’s profile page on the CME list above, you will see on the right hand side this broker’s specialties (a list of industries and/or financial products). As of this articles publication (Nov. 24, 2017), only one broker has added Bitcoin to his list of specialties: Level Trading Field LLC. However, this does not mean that the other brokers won’t handle Bitcoin futures. We expect that more of them will adopt this specialty as soon as Bitcoin futures are on the market.
For the three most recent fiscal years, each Fund that was operational for the period indicated paid ProShare Advisors the amount set forth below pursuant to the Management Services Agreement. Because the New Fund was not operational at the end of the Trust’s last fiscal year, information on fees paid pursuant to the Management Services Agreement by the New Fund is not included in this SAI.

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.

Darknet markets present challenges in regard to legality. Bitcoins and other forms of cryptocurrency used in dark markets are not clearly or legally classified in almost all parts of the world. In the U.S., bitcoins are labelled as "virtual assets". This type of ambiguous classification puts pressure on law enforcement agencies around the world to adapt to the shifting drug trade of dark markets.[94]
A Fund’s ability to invest in MLPs that are treated as qualified publicly traded partnerships (“QPTPs”) for federal income tax purposes is limited by the Fund’s intention to qualify as a RIC, and if the Fund does not appropriately limit such investments or if such investments are recharacterized for U.S. tax purposes, the Fund’s status as a RIC may be jeopardized. Among other limitations, a Fund is permitted to have no more than 25% of the total value if its total assets invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in QPTPs including MLPs. A Fund’s investments in MLPs potentially will result in distributions from that Fund (i) constituting returns of capital not included in a shareholder’s income but reducing the shareholder’s tax basis in his or her shares; (ii) attributable to gain recognized with respect to that is recharacterized as ordinary income and, therefore, not offset by capital losses; or (iii) taxable to such shareholder even though they represent appreciation realized by that Fund prior to the shareholder’s investment therein. That Fund’s investments in MLPs will also potentially cause it to recognize taxable income on its investments in in excess of the cash generated thereby, and therefore require the Fund to sell investments, including when not otherwise advantageous to do so, in order to satisfy the distribution requirements for treatment as a RIC and to eliminate a Fund-level tax.
The price of bitcoin may change sharply while the market for certain Bitcoin Instruments is closed or when the exchange on which Fund shares are traded is closed. Although the Funds will not invest directly in bitcoin, such price changes could impact the price and volatility of the Bitcoin Instruments in which the Funds invest and, therefore, could have a negative impact on your investment in the Funds.

Although shares of the fund are listed for trading on a stock exchange and may be listed or traded on other U.S. and non-U.S. stock exchanges, there can be no assurance that an active trading market for the Fund’s shares will develop or be maintained. Trading in shares on an exchange may be halted due to market conditions or for reasons that, in the view of an exchange, make trading in shares inadvisable. In addition, trading in shares on an exchange is subject to trading halts caused by extraordinary market volatility pursuant to exchange “circuit breaker” rules. Short selling of shares is also limited pursuant to SEC rules if the trading price of shares varies by more than 10% from the previous day’s closing price on the exchange. There can be no assurance that the requirements of the exchange necessary to maintain the listing of the Fund will continue to be met or will remain unchanged or that the shares will trade with any volume, or at all, on any stock exchange.

Since a portion of the Fund’s assets are invested in short positions in bitcoin futures contracts, the Fund will likely decline in value when the price of bitcoin futures contracts goes up (unless such losses are offset by gains in the value of the Fund’s positions in other investments), a result that is the opposite from the results of taking long positions in bitcoin futures contracts.

  •   Risks Associated with Bitcoin – The Fund is exposed to risks associated with bitcoin. Investing in or gaining exposure to Bitcoin may provide the Fund with increased risk. Various global factors may negatively impact the Fund’s performance including legal, regulatory, political, social, regional and economic events. These risks, which could have a negative impact on the performance of the Fund and the trading price of Fund shares, include the following:

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]
  •   A new competing digital asset may pose a challenge to bitcoin’s current market dominance, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin. It is possible that other digital currencies and trading systems could become more widely accepted and used than Bitcoin. The rise of such currencies could lead to a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin.
Important agents interacting with those prices are operating in one of three roles: individual speculator, market maker, or arbitrageur. A key role is market maker—a firm that has agreed to simultaneously act as both a buyer and seller for a specific security. When companies sign up for this role they agree to keep the bid/ask prices relatively close to each other—for example even if they aren’t keen on selling Bitcoins at the moment they can’t just set the ask price to an outrageous level. The agreed-upon maximum bid/ask ranges might be tied to market conditions (e.g., wider when deemed a “fast market”) and might allow time-outs but in general, the market maker agrees to act as a buffer between supply and demand.
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.

If the Funds engage in offsetting transactions, the Funds will incur a gain or loss, to the extent that there has been movement in forward currency contract prices. If forward prices go down during the period between the date a Fund enters into a forward currency contract for the sale of a currency and the date it enters into an offsetting contract for the purchase of the currency, the Fund will realize a gain to the extent that the price of the currency it has agreed to sell exceeds the price of the currency it has agreed to buy. If forward prices go up, the Fund will suffer a loss to the extent the price of the currency it has agreed to buy exceeds the price of the currency it has agreed to sell.

  shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

There's a lot of ins and outs which can get confusing in arbitrage trading. We won't go into the technicals of why futures contracts trade at a premium to spot price. You can read a full explanation here. If it's not of interest to you, all you need to know is that there's a tendency, the further out in time the futures contract expires, for the premium to spot to be higher and higher in nominal percentage terms.
