(c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid—generally, taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
Special rules would apply if a Fund were a qualified investment entity (“QIE”) because it is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition of USRPIs described below. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs generally are defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the last five years. A Fund that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and RICs that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in RICs generally are not USRPIs, but these exceptions do not apply for purposes of determining whether a Fund is a QIE.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[89] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.

  (c) A “Disinterested Trustee” is one (i) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustees, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (ii) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending;
Maintenance Margin - this is the % of the position value you have to have in your account at the very minimum to avoid being Margin Called.  In some exchanges, margin call will mean you get notified and must deposit more margin to avoid liquidation (like CryptoFacilities). On other exchanges you will at this point be liquidated out of your position. So if maintenance margin is 5%, then the 0.05 BTC of your initial margin will need to be kept for the position to be alive.
Margin-trading is what provides the real reward and potential in daytrading bitcoin. You will be able to access the leverage to profit well from relatively small moves in BTC/USD price. High risk, high reward, high potential for loss. However, you need not use Futures only to speculate, hedging on lower leverage is also a great use case for Bitcoin derivatives if you just want to defend your coins. 
Coinbase is not alone in making moves toward becoming an ATS. Recently, mobile payment app company Circle acquired Poloniex, another U.S.-based exchange, with plans to “clean up” the exchange. A slide that was initially leaked from a Circle presentation stated, “Circle has briefed the SEC on the transaction and indicated that upon closing that we will begin the process of registering the new entity with the SEC and FINRA as a Broker/Dealer and in turn as a licensed ATS…”

Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. In many of these instances, the customers of such Bitcoin Exchanges were not compensated or made whole for the partial or complete losses of their account balances in such Bitcoin Exchanges. No Bitcoin Exchange is immune from these risks but the existence of these risks has created a higher barrier of entry for new Bitcoin Exchanges. The loss of confidence in new and smaller Bitcoin Exchanges and in the Bitcoin Exchange Market overall can slow down the mass adoption of bitcoin. Further, the failure of the Bitcoin Exchange Market or any other major component of the overall bitcoin ecosystem can have consequences for the Bitcoin Network, have an adverse effect on the price of bitcoin and could have a negative impact on the Bitcoin Instruments in which certain of the Funds invest.
Collateralized mortgage obligations (“CMOs”) are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collateral collectively hereinafter referred to as “Mortgage Assets”). Multi-class pass-through securities are interests in a trust composed of Mortgage Assets and all references in this section to CMOs include multi-class pass-through securities. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semi-annual basis. The principal and interest payments on the Mortgage Assets may be allocated among the various classes of CMOs in several ways. Typically, payments of principal, including any prepayments, on the underlying mortgages are applied to the classes in the order of their respective stated maturities or final distribution dates, so that no payment of principal is made on CMOs of a class until all CMOs of other classes having earlier stated maturities or final distribution dates have been paid in full.
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).

Traders A and B in the previous example are hedgers. However, futures contracts, once they exist, can also be bought and sold in their own right. This is where futures get interesting for speculators. Say that Speculator X believes the price of a ton of pork belly will rise to 1,200 USD in 3 months’ time, so buying the futures contract at 1,000 USD is a good deal. He can then sell the contract to bacon producers who want to buy pork bellies at 1,000 USD. The option to buy at a specified price in the future is known as a call option. The price of call options rise when traders assume that the price of the underlying asset will rise.
