Under certain circumstances, a Fund may recognize gain from a constructive sale of an “appreciated financial position” it holds if it enters into a short sale, forward contract or other transaction that substantially reduces the risk of loss with respect to the appreciated position. In that event, the Fund would be treated as if it had sold and immediately repurchased the property and would be taxed on any gain (but would not recognize any loss) from the constructive sale. The character of gain from a constructive sale would depend upon each Fund’s holding period in the property. Appropriate adjustments would be made in the amount of any gain or loss subsequently realized on the position to reflect the gain recognized on the constructive sale. Loss from a constructive sale would be recognized when the property was subsequently disposed of, and its character would depend on the Fund’s holding period and the application of various loss deferral provisions of the Code. Constructive sale treatment does not generally apply to a transaction if such transaction is closed on or before the end of the 30th day after the close of the Fund’s taxable year and the Fund holds the appreciated financial position throughout the 60-day period beginning with the day such transaction closed. The term “appreciated financial position” excludes any position that is “marked-to-market.”
As the SEC spelled out in its statement on March 7, 2018, any entity that wants to become an ATS needs to register with the SEC as a broker-dealer and become a member of a self-regulating organization (SRO), such as the Financial Industry Regulatory Authority (FINRA). “An ATS must comply with the federal securities laws and its SRO's rules and file a Form ATS with the SEC,” the statement reads.
​Trading these futures instead of actual bitcoins is smart because you are able to access higher leverage by entering contracts with counterparties, while keeping your coins safe in cold storage or elsewhere. Additionally, unlike trading margin on Kraken or Bitfinex, you do NOT have to pay interest on the leverage you have! This is the result of the counterparty structure of futures. High leverage trading, low-fees, and high profit potential.
Index options are subject to substantial risks, including the risk of imperfect correlation between the option price and the value of the underlying assets composing the index selected, the possibility of an illiquid market for the option or the inability of counterparties to perform. Because the value of an index option depends upon movements in the level of the index rather than the
Whether a Fund realizes a gain or loss from futures activities depends generally upon movements in the underlying currency, commodity, security or index. The extent of a Fund’s loss from an unhedged short position in futures contracts or from writing options on futures contracts is potentially unlimited, and investors may lose the amount that they invest plus any profits recognized on their investment. The Funds may engage in related closing transactions with respect to options on futures contracts. The Funds will engage in transactions in futures contracts and related options that are traded on a U.S. exchange or board of trade or that have been approved for sale in the U.S. by the Commodity Futures Trading Commission (“CFTC”).
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
Unlike many commodity futures, Bitcoin futures are cash settled rather than physically settled.  Cash settlement is a relatively new development in futures trading, first introduced in 1981 for Eurodollar futures, that addresses the problem of how to settle futures contracts on things that are difficult/impossible to deliver physicially—things like interest rates, large stock indexes (e.g., S&P 500), and volatility indexes (Cboe’s VIX).  Futures physical settlement involves actual shipment/change of ownership of the underlying product to the contract holder but in practice, it’s rarely used (~2% of the time).  Instead, most organizations that are using futures to hedge prices of future production/usage will make separate arrangements with suppliers/customers for physical delivery and just use the futures to protect against contrary price changes.  In practice, the final settlement price of the contract can be used to provide the desired price protection regardless of whether the futures contract specifies physically delivery or cash-settlement.
For each intervening holiday in the applicable foreign market that is not a holiday observed by the U.S. equity markets, the redemption settlement cycle will be extended by the number of days of such intervening holiday. In addition to holidays, other unforeseeable closings in a foreign market, including due to regulatory action, may also prevent a Fund from delivering securities within the normal settlement period.

The Funds may invest in a combination of forward currency contracts and U.S. dollar-denominated market instruments in an attempt to obtain an investment result that is substantially the same as a direct investment in a foreign currency-denominated instrument. This investment technique creates a “synthetic” position in the particular foreign currency instrument whose performance the manager is trying to duplicate. For example, investing in a combination of U.S. dollar-denominated instruments with “long” forward currency exchange contracts creates a position economically equivalent to investing in a money market instrument denominated in the foreign currency itself. Such combined positions are sometimes necessary when the money market in a particular foreign currency is small or relatively illiquid.
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.
