Another huge pain point for institutional investors is portfolio management. Investors face major difficulties in tracking their real time and historical P&L (profits & loss). Our PMS (Portfolio Management System) allows users to see real-time and historical P&L over any time interval, as well as perform real-time monitoring of positions across exchanges and wallets.
The Funds may invest in shares of foreign corporations that are classified under the Code as passive foreign investment companies (“PFICs”). In general, a foreign corporation is classified as a PFIC if at least one-half of its assets constitute investment-type assets, or 75% or more of its gross income is investment-type income. Certain distributions from a PFIC, as well as gain from the sale of PFIC shares, are treated as “excess distributions.” Excess distributions are taxable as ordinary income even though, absent
Do you remember, like, two weeks ago, when people were talking about how the launch of bitcoin futures at Cboe Global Markets Inc. and CME Group Inc. would allow for efficient short-selling of bitcoin and finally deflate the bubble? Smart hedge-fund money was lining up to bet against bitcoin, the thinking went, but had no convenient way to do it on the actual bitcoin exchanges. The only people trading bitcoin were the true believers, so of course it kept going up, but once it was opened up to normal financial players that would end. "The futures reduce the frictions of going short more than they do of going long, so it’s probably net bearish," said Craig Pirrong. 
In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[38] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[38] With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[38][39]
Cryptocurrencies are far more volatile than stocks and bonds, and the industry evolves rapidly. An altcoin that is popular today may not exist a month or a year from now. In other words, traders should consider the possibility of losing everything when they start trading. For this reason, you should put only a very small portion of your portfolio in this sector.

Investments by a Fund in a wholly-owned foreign subsidiary, debt obligations issued or purchased at a discount and certain derivative instruments could cause the Fund to recognize taxable income in excess of the cash generated by such investments, potentially requiring the Fund to dispose of investments (including when otherwise disadvantageous to do so) in order to meet
Market conditions should be considered favorable to a Fund when such conditions make it more likely that the value of an investment in that Fund will increase. Market conditions should be considered adverse to a Fund when such conditions make it more likely that the value of an investment in that Fund will decrease. For example, market conditions that cause the level of the S&P 500® to rise are considered “favorable” to the Ultra S&P500® and are considered “adverse” to the Short S&P500®.
Additions such as Zerocoin have been suggested, which would allow for true anonymity.[54][55][56] In recent years, anonymizing technologies like zero-knowledge proofs and ring signatures have been employed in the cryptocurrencies Zcash and Monero, respectively. Cryptocurrency anonymizing implementations such as Cloakcoin, Dash, and PIVX use built in mixing services, also known as tumblers.[57]
Other countries are not as accommodative of bitcoin. For example, the Chinese government on December 3, 2013 issued a notice that classified bitcoin as legal and “virtual commodities;” however, the same notice restricted the banking and payment industries from using bitcoin, creating uncertainty and limiting the ability of Bitcoin Exchanges to operate in the then-second largest bitcoin market. Then on September 15, 2017, the Chinese government and local financial regulators officially requested some Chinese Bitcoin Exchanges and digital asset trading platforms to shut down by the end of September 2017. In addition, the Central Bank of Bolivia banned the use of bitcoin as a means of payment in May 2014. Further, in July 2016, the Russian Ministry of Finance indicated it supports a proposed law that bans bitcoin domestically but allows for its use as a foreign currency. In September 2017 the head of the Russian central bank stated that it is categorically against regulating cryptocurrencies as money, as a means by which payment can be made for goods and services, and against equating them with foreign currency. Most recently, South Korea’s Office for Government Policy Coordination released a wide variety of proposed regulations which range from the imposition of capital gains taxes on profits realized from cryptocurrency trading, to banning minors from registering on South Korean bitcoin exchanges, and even prohibiting financial institutions from investing in digital assets. These restrictive stances towards digital assets may reduce the rate of expansion of bitcoin use or even eliminate the use of bitcoin entirely in these geographies.
Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[95] and economic bubbles,[96] such as housing market bubbles.[97] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[98]

•	 	Non-Diversification Risk — The Fund is classified as “non-diversified” under the 1940 Act, and has the ability to invest a relatively high percentage of its assets in the securities of a small number of issuers susceptible to a single economic, political or regulatory event, or in financial instruments with a single counterparty or a few counterparties. This may increase the Fund’s volatility and cause performance of a relatively smaller number of issuers or the credit of one or a relatively smaller number of counterparties to have a greater impact on the Fund’s performance. This risk may be particularly acute if the Fund is comprised of a small number of securities. Notwithstanding the Fund’s status as a “non-diversified” investment company under the 1940 Act, the Fund intends to qualify as a “regulated investment company” accorded special tax treatment under the Internal Revenue Code, which imposes its own diversification requirements that are less restrictive than the requirements applicable to “diversified” investment companies under the 1940 Act.

Options give the holder of the option the right to buy (or to sell) a position in a security or in a contract to the writer of the option, at a certain price. There may be imperfect correlation, or even no correlation, between price movements of an options contract and price movements of investments underlying an options contract. Lack of correlation (or tracking) may be due to factors unrelated to the value of the investments being hedged, such as speculative or other pressures on the markets in which these instruments are traded. Consequently, the effectiveness of bitcoin options in providing exposure to the price movements of options will depend, in part, on the degree of correlation between price movements in the derivatives and price movements in underlying bitcoin markets. Exchanges can limit the number of positions that can be held or controlled by the Fund or the Sub-Adviser, thus limiting the ability to implement the Fund’s strategies. Options are also particularly subject to leverage risk and can be subject to liquidity risk.
Market Price Variance Risk — Fund shares are listed for trading on the [                ] Exchange and can be bought and sold in the secondary market at market prices. The market price of shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares and other market factors. In addition, the securities held by the Fund may be traded in markets that close at a different time than the Exchange. Because the Fund generally values such securities as of its local market closing time, the daily net asset value (“NAV”) may vary from the market performance of the Fund as of the Exchange close (typically at [ ] p.m., Eastern Time). Furthermore, liquidity in such securities may be reduced after the applicable closing times. This may cause wider spreads and larger premium and discounts than would otherwise be the case if each market was open until the close of trading on the Exchange. ProShare Advisors cannot predict whether shares will trade above, below or at a price equal to the value of the Fund’s holdings. Given the fact that shares can be created and redeemed in Creation Units, as defined below, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained. The Fund’s investment results are measured based upon the daily NAV of the Fund.

Municipal notes with maturities of three years or less are usually given note ratings (designated SP-1 or SP-2) to distinguish more clearly the credit quality of notes as compared to bonds. Notes rated SP-1 have a very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are given the designation of SP-1+. Notes rated SP-2 have a satisfactory capacity to pay principal and interest.


ProShare Advisors is also responsible for the general management and administration of each Subsidiary, pursuant to separate investment advisory and management agreements. Under those advisory and management agreements, ProShare Advisors provides each Subsidiary with the same type of services under essentially the same terms (except at no cost to such Subsidiary) as are provided for its respective Parent Fund.
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.
