Let's not even go into the paradigm shift that this development implies. The growth of a bitcoin futures market positions it even more as a commodity than a currency (in the US, the Commodity Futures Trading Commission regulates futures markets). And even more as an investment asset than a technology that has the potential to change the plumbing of finance.
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.
Shareholders that are U.S. persons and own, directly or indirectly, more than 50% of a Fund could be required to report annually their “financial interest” in the Fund’s “foreign financial accounts,” if any, on FinCEN Form 114, Report of Foreign Bank and Financial Accounts (“FBAR”). Shareholders should consult a tax advisor, and persons investing in a Fund through an intermediary should contact their intermediary, regarding the applicability to them of this reporting requirement.

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 table below shows a performance example of a Short ProShares Fund that has an investment objective to correspond to the inverse (-1x) of the daily performance of an index. In the chart below, areas shaded lighter represent those scenarios where a Short ProShares Fund will return the same or outperform (i.e., return more than) the index performance; conversely, areas shaded darker represent those scenarios where a Short ProShares Fund will underperform (i.e., return less than) the index performance.
If I held the opinion that an asset was going to go one way, but then made the research and it turned out that I started thinking it might actually be headed the other way, I should feel no obligation to hold on to my original opinion, just because I didnt want to feel I’ve been initially wrong. This seems obvious but is much tougher in practice for inexperienced investors.

The Distribution and Service Plan and Distribution and Service Agreements will remain in effect for a period of one year and will continue in effect thereafter only if such continuance is specifically approved annually by a vote of the Trustees. All material amendments of the Distribution and Service Plan must also be approved by the Board. The Distribution and Service Plan may be terminated at any time by a majority of the Board or by a vote of a majority of the outstanding Shares, as defined under the 1940 Act, of the affected Fund. The Distribution and Service Agreements may be terminated at any time, without payment of any penalty, by vote of a majority of the Independent Trustees or by a vote of a majority of the outstanding Shares, as defined under the 1940 Act, of the affected Fund on not less than 60 days’ written notice to any other party to the Distribution and Service Agreements. The Distribution and Service Agreements shall terminate automatically if assigned. The Board has determined that, in its judgment, there is a reasonable likelihood that the Distribution and Service Plan will benefit the Funds and holders of Shares of the Funds. In the Board’s quarterly review of the Distribution and Service Plan and Distribution and Service Agreements, the Trustees will consider their continued appropriateness and the level of compensation and/or reimbursement provided therein.
You may wonder: where do these contracts come from? We know on the spot market that bitcoins are being bought and sold for fiat, but how the heck are bitcoins being used to trade bitcoin futures contracts? Let's walk through a really simple example showing how an exchange functions when there's just a simple two traders who want to go long and short. 
If this sounds confusing to you, then don't worry. In practice, these futures contracts are just like buying and selling spot market value. Just focus on the price of the contract and whether you are LONG or SHORT. If you're long and the futures price goes up, the BTC value of the contract goes up and you have bought an asset that is increasing in value.
Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s
Unsponsored ADR programs are organized independently and without the cooperation of the issuer of the underlying securities. As a result, available information concerning the issuers may not be as current for unsponsored ADRs, and the price of unsponsored depositary receipts may be more volatile than if such instruments were sponsored by the issuer and/or there may be no correlation between available information and the market value.
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.

This means simply that you put down 1 bitcoin and you can trade 20 on OKCoin, or 100 bitcoin on BitMEX. The multiple refers to the initial margin you need to open the nominal position value. You simply set the margin aside as collateral, and if the position goes against you, the collateral will be used to exit your position into a liquidation, or margin call.


As discussed in more detail below, FATCA (as defined below) generally imposes a reporting and 30% withholding tax regime with respect to certain U.S.-source income (“withholdable payments”) paid to “foreign financial institutions” and certain other non-U.S. entities when those entities fail to satisfy the applicable account documentation, information reporting, withholding, registration, certification and/or other requirements applicable to their status under FATCA. A Subsidiary will be subject to the 30% withholding tax in respect of any withholdable payment it receives if it fails to satisfy these requirements, as may be applicable to the Subsidiary. Each Subsidiary expects to satisfy these requirements, as may be applicable to it, so as to avoid this additional 30% withholding. See “Certain Additional Reporting and Withholding Requirements” below for more discussion of these rules.
The Bitcoin Network and bitcoin, as an asset, currently hold a “first-to-market” advantage, often referred to as a “network effect,” over other digital assets. This first-to-market advantage has resulted in the Bitcoin Network evolving into the most well developed network of any digital asset. The Bitcoin Network enjoys the largest user base of any digital asset and, more importantly, the largest combined mining power in use to secure the Bitcoin Blockchain. Having a large mining network enhances user confidence regarding the security of the Bitcoin Blockchain and long-term stability of the Bitcoin Network. Despite the marked network effect advantage of the Bitcoin Network over other digital assets, it is possible that real or perceived shortcomings in the Bitcoin Network, technological, regulatory or other developments could result in a decline in popularity and acceptance of bitcoin and the Bitcoin Network.
"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."
It bears repeating -- when trading futures on leverage, you are not "borrowing" the money, so you don't have to pay a financing rate on your positions. Even though you are 100x exposed, you don't have to pay 100x financing (unless you're trading the perpetual swap, which is not a futures contract, but has similar characteristics). Since bitcoin futures do tend to trade at a premium, you are in a way paying an implied interest rate in the contract, because if you want to go long, you have to pay above spot, so you pay the interest up front in the contract, in a way.

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]
While it is likely that regulatory laws surrounding ICOs will only be settled in court (perhaps even the Supreme Court), if ICO tokens are legally classified as securities, any exchange that wants to list those tokens needs to either register as a national securities exchange or operate under an exemption and set itself up as an alternative trading system (ATS).

If the tip is valid, it would make Morgan Stanley the latest in legacy financial groups looking to open a doorway for institutional investors to enter the cryptocurrency market. Despite false reports claiming that Goldman Sachs had put hopes for a bitcoin strategy behind it, the bank has a strategy desk in the works, a service that, if opened, would add to the bitcoin futures options it facilitates for its clients.
In the course of providing advisory services, the Advisor may simultaneously recommend the sale of a particular security for one account while recommending the purchase of the same security for another account if such recommendations are consistent with each client’s investment strategies. The Advisor also may recommend the purchase or sale of securities that may also be recommended by ProFund Advisors LLC, an affiliate of the Advisor.

The Funds may engage in short sales transactions. A short sale is a transaction in which a Fund sells a security it does not own in anticipation that the market price of that security will decline. To complete such a transaction, a Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by borrowing the same security from another lender, purchasing it at the market price at the time of replacement or paying the lender an amount equal to the cost of purchasing the security. The price at such time may be more or less than the price at which the security was sold by the Fund. Until the security is replaced, the Fund is required to repay the lender any dividends it receives, or interest which accrues, during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The net proceeds of the short sale will be retained by the broker, to the extent necessary to meet the margin requirements, until the short position is closed out. A Fund also will incur transaction costs in effecting short sales.
Distributions of Shares shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants. The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial owners owning through such DTC Participants.
If anything, the problem seems to start with incredibly lax risk management at this exchange.  According to the OKEX statement, the risk management team 'immediately' contacted the client to reduce the size of the trade - begging the question - how did their risk management system allow the trade to occur in the first place?  On the bright side, something like that should be easy to fix, but it is indicative, potentially of how many simple things are being overlooked in the rush to make money from crypto trading.
A Bitcoin futures contract is exactly what you would expect from the example above, replacing pork bellies with Bitcoin. It is a contract that enables you to buy Bitcoin at a predetermined price at a specific point in the future. For example, if today’s Bitcoin price is 8,000 USD per BTC and you expect it to rise to 10,000 USD per BTC in 4 weeks, then entering a contract which allows you to buy Bitcoin at 9,000 USD in 4 weeks is highly attractive.
