An increase in cryptocurrency mining increased the demand of graphics cards (GPU) in 2017.[49] Popular favorites of cryptocurrency miners such as Nvidia’s GTX 1060 and GTX 1070 graphics cards, as well as AMD’s RX 570 and RX 580 GPUs, doubled or tripled in price – or were out of stock.[50] A GTX 1070 Ti which was released at a price of $450 sold for as much as $1100. Another popular card GTX 1060's 6 GB model was released at an MSRP of $250, sold for almost $500. RX 570 and RX 580 cards from AMD were out of stock for almost a year. Miners regularly buy up the entire stock of new GPU's as soon as they are available.[51]
The tax rules are uncertain with respect to the treatment of income or gains arising in respect of commodity-linked exchange-traded notes (“ETNs”) and certain commodity-linked structured notes; also, the timing and character of income or gains arising from ETNs can be uncertain. An adverse determination or future guidance by the IRS (which determination or guidance could be retroactive) may affect a Fund’s ability to qualify for treatment as a regulated investment company and to avoid a Fund-level tax.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[99] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[100] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[101] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[102] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[103] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
R-1 (low) – Short term debt rated “R-1 (low)” is of good credit quality. The overall strength and outlook for key liquidity, debt and profitability ratios is not normally as favorable as with higher rating categories, but these considerations are still respectable. Any qualifying negative factors which exist are considered manageable, and the entity is normally of sufficient size to have some influence in its industry.
A bitcoin exchange operates somewhat similarly to online stock trading brokers, where customers deposit their fiat currency (or bitcoins) to carry out trades. However, not all bitcoin exchanges offer such services. Some exchanges are more like wallets and thus provide limited trading options or storage of currency (both digital and fiat) for trading. The bigger and more elaborate exchanges offer trades between different cryptocurrencies, as well as between digital and fiat currencies. The number of currencies supported by an exchange varies from one exchange to another. (For more, see: Why Is Bitcoin’s Value So Volatile.)

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.

If a Fund purchases in the secondary market a debt security that has a fixed maturity date of more than one year from its date of issuance at a price lower than the stated redemption price of such debt security (or, in the case of a debt security issued with “original issue discount” (described below), a price below the debt security’s “revised issue price”), the excess of the stated redemption price over the purchase price is “market discount.” If the amount of market discount is more than a de minimis amount, a portion of such market discount must be included as ordinary income (not capital gain) by a Fund in each taxable year in which the Fund owns an interest in such debt security and receives a principal payment on it. In particular, the Fund will be required to allocate that principal payment first to the portion of the market discount on the debt security that has accrued but has not previously been includable in income. In general, the amount of market discount that must be included for each period is equal to the lesser of (i) the amount of market discount accruing during such period (plus any accrued market discount for prior periods not previously taken into account) or (ii) the amount of the principal payment with respect to such period. Generally, market discount accrues on a daily basis for each day the debt security is held by a Fund at a constant rate over the time remaining to the debt security’s maturity or, at the election of the Fund, at a constant yield to maturity which takes into account the semi-annual compounding of interest. Gain realized on the disposition of a market discount obligation must be recognized as ordinary interest income (not capital gain) to the extent of the accrued market discount.

reduce the amount of the Fund’s borrowings to the extent necessary to meet this 300% coverage requirement. Maintenance of this percentage limitation may result in the sale of portfolio securities at a time when investment considerations would not favor such sale. In addition to the foregoing, the Funds are authorized to borrow money as a temporary measure for extraordinary or emergency purposes in amounts not in excess of 5% of the value of each Fund’s total assets. This borrowing is not subject to the foregoing 300% asset coverage requirement. The Funds are authorized to pledge portfolio securities as ProShare Advisors deems appropriate in connection with any borrowings.

Each Fund intends to invest in bitcoin futures contracts. The Funds will not invest directly in bitcoin and are not benchmarked to the current price of bitcoin. The value of the bitcoin futures contracts is generally based on the expected value of bitcoin at a future point in time, specifically, the expiration date of the bitcoin futures contracts. Other factors, such as cost of mining, storing and securing bitcoin may affect the value of bitcoin futures. A change in the price of bitcoin today (sometimes referred to as the “spot” price) will not necessarily result in a corresponding movement in the price of the bitcoin futures contracts since the price of the bitcoin futures contracts is based on expectations of the price of bitcoin at a future point in time. Additionally, there is no one centralized source for pricing bitcoin and pricing from one bitcoin exchange to the next can vary widely. Additionally, each Fund has the ability to invest in, or take a short position in, bitcoin futures contracts offered by CFE or CME, each of which uses a different exchange, or exchanges, to determine the value of bitcoin, which may lead to material differences in the value of the bitcoin futures contracts offered by CFE and CME. As a result, each Fund should be expected to perform very differently from the performance of the spot price of bitcoin (or the inverse of such performance) over all periods of time.
Anyone interested in buying bitcoins needs to deposit funds in U.S. dollars, euros, or another currency supported by the exchange. The popular methods of transferring money to the currency exchanges are through bank wire transfers, credit cards, or liberty reserves. One of the pre-requisites here is to have a digital wallet to hold bitcoins. Bitcoins bought can be stored in a digital wallet, device, or paper wallet, depending on the buyer’s preference. For sellers, the fait currency for which the Bitcoins have been sold needs to be withdrawn from the exchange and sent to a bank. One issue that can arise is if the exchange has liquidity concerns at a particular point in time; such situations can delay withdrawal and transfer of funds into a bank account.

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
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.
