•   Interest Rate Risk — The Fund intends to invest a substantial portion of its assets in U.S. Treasury securities and is subject to interest rate risk. Interest rate risk is the risk that debt securities may fluctuate in value due to changes in interest rates. Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities may fluctuate more in response to interest rate changes than securities with shorter maturities. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). This risk may be elevated under current economic conditions because interest rates are at historically low levels. Returns on investment in debt instruments may trail the returns on other investment options, including investments in equity securities.
The first U.S. bitcoin futures are here. Bitcoin futures opened for trading on the Cboe Futures Exchange, LLC (CFE) on December 10, 2017. This is one of the biggest milestones for bitcoin since it emerged in the wake of the 2008-09 financial crisis. Bitcoin futures will bring much-needed transparency, greater liquidity and efficient price discovery to the ecosystem. Cboe will be soon joined by CME Group as it prepares to launch bitcoin futures contracts on December 18, 2017.

If a Fund were a QIE, under a special “look-through” rule, any distributions by the Fund to a foreign shareholder (including, in certain cases, distributions made by the Fund in redemption of its shares) attributable directly or indirectly to (i) distributions received by the Fund from a lower-tier RIC or REIT that the Fund is required to treat as USRPI gain in its hands and (ii) gains realized on the disposition of USRPIs by the Fund would retain their character as gains realized from USRPIs in the hands of the Fund’s foreign shareholders and would be subject to U.S. tax withholding. In addition, such distributions could result in the foreign shareholder being required to file a U.S. tax return and pay tax on the distributions at regular U.S. federal income tax rates. The consequences to a foreign shareholder, including the rate of such withholding and character of such distributions (e.g., as ordinary income or USRPI gain), would vary depending upon the extent of the foreign shareholder’s current and past ownership of the Fund.

These are fundraising mechanisms for newly launched cryptocurrencies. Investors in ICOs receive tokens in the new venture. Investors have poured billions of dollars into more than 1,000 ICOs over the past year. While many ICOs are legitimate, the vast majority have no real business plans or technology behind them. Many get launched with nothing more than a whitepaper by individuals with no technology or industry experience.
CCC/CC/C – Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.

Some exchanges offer trading on margin. When such an option is available, Bitcoiners are allowed to borrow funds from peer liquidity providers to carry out trades. The term "liquidity provider" refers to those who are ready to deposit their bitcoins and/or dollars with the exchange for use by others for a certain pre-fixed duration, rate, and amount. For example, say a Bitcoiner wants to buy 20 Bitcoins, anticipating that its price would rise in future and thus hopes to profit by selling them at a later date. If the person does not have sufficient funds to buy the 20 bitcoins, the margin facility allows him to borrow the amount required (20 X the price of bitcoins in USD) from a liquidity provider. When the Bitcoiner chooses to close the position, he needs to repay the amount borrowed plus the interest accrued during this time period. Remember that the amount accrued (loan + interest) needs to be reimbursed regardless of profit or loss at the time of settlement.

In traditional financial markets, derivatives are used as speculation objects as well as insurance against losses. The latter is known as hedging. One popular variety of derivatives used for hedging are called futures. A future is a contract between two parties in which one party agrees to pay the other a predetermined amount of money for an underlying asset at a specific point in time.
