The Funds may invest directly or indirectly in residual interests in real estate mortgage conduits (“REMICs”) (including by investing in residual interests in collateralized mortgage obligations (“CMOs”) with respect to which an election to be treated as a REMIC is in effect) or taxable mortgage pools (“TMPs”). Under a Notice issued by the IRS in October 2006 and Treasury regulations that have yet to be issued but may apply retroactively, a portion of a Fund’s income (including income allocated to the Fund from a REIT or other pass-through entity) that is attributable to a residual interest in a REMIC or an equity interest in a TMP (referred to in the Code as an “excess inclusion”) will be subject to federal income tax in all events. This Notice also provides, and the regulations are expected to provide, that excess inclusion income of a RIC will be allocated to shareholders of the RIC in proportion to the dividends received by such shareholders, with the same consequences as if the shareholders held the related interest directly. As a result, Funds investing in such interests may not be a suitable investment for charitable remainder trusts (see Unrelated Business Taxable Income, below).

On September 17, 2015, the CFTC provided clarity regarding the regulatory treatment of bitcoin in the Coinflip civil enforcement case. There the CFTC determined that bitcoin and other virtual currencies are regulated as commodities under the CEA. Based on this determination, the CFTC applied CEA provisions and CFTC regulations that apply to a bitcoin derivatives trading platform. Also of significance, the CFTC took the position that bitcoin is not encompassed by the definition of currency under the CEA and CFTC regulations. The CFTC defined bitcoin and other “virtual currencies” as “a digital representation of value that functions as a medium of exchange, a unit of account, and/or a store of value, but does not have legal tender status in any jurisdiction. Bitcoin and other virtual currencies are distinct from ‘real’ currencies, which are the coin and paper money of the United States or another country that are designated as legal tender, circulate, and are customarily used and accepted as a medium of exchange in the country of issuance.” On July 6, 2017, the CFTC granted LedgerX, LLC an order of registration as a Swap Execution Facility for digital assets and on July 24, 2017, the CFTC approved Ledger X, LLC as the first derivatives clearing organization for digital currency. On September 21, 2017, the CFTC filed a civil enforcement action in federal court against a New York corporation and its principal, charging them with fraud, misappropriation, and issuing false account statements in connection with a Ponzi scheme involving investments in bitcoin, which the CFTC asserted is a commodity subject to its jurisdiction.
  pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its 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.
The most important feature of futures is that you never have to sell bitcoin ever again. Seriously. Why would you sell into fiat when you are concerned about a possible price drop? If you want to short bitcoin, then with futures you can simply "sell" or "short" the derivatives contracts and earn more bitcoin when the price drops -- so that your fiat value is the same or more if you use leverage. Of course you can also buy the contracts and  multiply your bitcoin when the bitcoin price goes up! But think for a moment how important this tool is: earn more bitcoin when the bitcoin price drops, and you effectively do NOT have to sell to fiat anymore. And with the power of margin leverage, you don't have to risk too much Bitcoin to take meaningful directional positions.

Each Fund may consider changing its index at any time, including if, for example: the current index becomes unavailable; the Board believes that the current index no longer serves the investment needs of a majority of shareholders or that another index may better serve their needs; or the financial or economic environment makes it difficult for the Fund’s investment results to correspond sufficiently to its current index. If believed appropriate, a Fund may specify an index for itself that is “leveraged” or proprietary. There can be no assurance that a Fund will achieve its objective.

  •   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.

Institutional-tier offerings such as those detailed above are seen as much-needed catalysts to stimulate the flow of institutional money into the market, offering heavyweight financial players a less-risky way to buy into assets like bitcoin. For the same reason, custody services like those offered by Coinbase, BitGo and others are necessary for safely storing and managing these investments as well.

The Code generally imposes a 3.8% Medicare contribution tax on the net investment income of certain individuals, trusts, and estates to the extent their income exceeds certain threshold amounts. For these purposes, “net investment income” generally includes, among other things, (i) distributions paid by a Fund of ordinary dividends and capital gain dividends as described above, and (ii) any net gain from the sale, redemption or exchange of Fund shares. Shareholders are advised to consult their tax advisors regarding the possible implications of this additional tax on their investment in a Fund.
The Funds may invest in bitcoin-based futures contracts, swap agreements, and options contracts, which are types of derivative contracts. A derivative refers to any financial instrument whose value is derived, at least in part, from the price of an underlying security, commodity, asset, rate, or index. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Changes in the value of a derivative may not correlate perfectly with the underlying security, asset, rate or index. Gains or losses in a derivative may be magnified and may be much greater than the derivative’s original cost. Because bitcoin-based derivatives were only recently introduced, the degree to which bitcoin-based derivatives are likely to provide exposure to movements in the price of bitcoin is extremely uncertain. If market participants executing trades in bitcoin-based derivatives face constraints, including capital constraints, security risks, or high execution costs with respect to direct investments in bitcoin, the price at which bitcoin-based derivatives trade may fail to capture price movements in the underlying price of bitcoin. Moreover, it is not clear how changes to the Bitcoin Network and determinations by any relevant derivatives exchange with respect to such changes to the Bitcoin Network will affect the value of any positions in bitcoin-based derivatives. [[In December 2015, the SEC proposed a new rule to regulate the use of derivatives by registered investment companies, such as the Fund. Whether and when this proposed rule will be adopted and its potential effects on the Fund are unclear as of the date of this Prospectus.]]
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.
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. 

Market Spotlight – Bitcoin - A cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure transactions, control creation, and verify transactions. The first such cryptocurrency, Bitcoin, was introduced in 2009. In 2017, the exchanges launched a Bitcoin futures contract. The CBOE contract launched on Sunday, December 10, while the CME contract launched on Monday, December 18.
One of the biggest issues for institutional investors is the fragmented nature of the market, requiring them to operate on several exchanges. Often, this forces them to come up with customized ways to deal with the limitations of each exchange — a time-consuming and frustrating exercise. Not only that, but this can lead to liquidity and slippage problems, as even small trades can consume liquidity and cause prices to slip.
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.
