If I held the opinion that an asset was going to go one way, but then made the research and it turned out that I started thinking it might actually be headed the other way, I should feel no obligation to hold on to my original opinion, just because I didnt want to feel I’ve been initially wrong. This seems obvious but is much tougher in practice for inexperienced investors.

On September 15, 2015, the Conference of State Bank Supervisors finalized their proposed model regulatory framework for state regulation of participants in “virtual currency activities.” The Conference of State Bank Supervisors proposed framework is a non-binding model and would have to be independently adopted, in sum or in part, by state legislatures or regulators on a case-by-case basis. In July 2017, the Uniform Law Commission (the “ULC”), a private body of lawyers and legal academics from the several U.S. states, voted to finalize and approve a uniform model state law for the regulation of virtual currency businesses, including bitcoin (the “Uniform Virtual Currency Act”). Having been approved by the ULC, the Uniform Virtual Currency Act now goes to each of the U.S. states and territories for their consideration and would have to be independently adopted, in sum or in part, by state legislatures or regulators on a case-by-case basis.

Distributions by the Fund to foreign shareholders other than Capital Gain Dividends, short-term capital gain dividends and interest-related dividends (e.g., dividends attributable to foreign-source dividend and interest income or to short-term capital gains or U.S. source interest income to which the exception from withholding described above does not apply) are generally subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate).

In the course of providing advisory services, the Advisor may simultaneously recommend the sale of a particular security for one account while recommending the purchase of the same security for another account if such recommendations are consistent with each client’s investment strategies. The Advisor also may recommend the purchase or sale of securities that may also be recommended by ProFund Advisors LLC, an affiliate of the Advisor.
Currently the front month future is the January contract which at last check could be sold for $17,600.  This contract settles in a cash transfer based on the 4:00 pm eastern bitcoin auction price on Wednesday January 17, 2018 established by Gemini who is partnering with Cboe Global Markets.  The bitcoin price at Gemini is close to $16,600 so I will use that for the underlying bitcoin price in this example. 
Qualifying Income described in clause (i) of subparagraph (a) above) will be treated as Qualifying Income. In general, such entities will be treated as partnerships for federal income tax purposes because they meet the passive income requirement under Code section 7704(c)(2). In addition, although in general the passive loss rules of the Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly traded partnership. Moreover, the amounts derived from investments in foreign currency will be treated as Qualifying Income for purposes of subparagraph (a) above. There is a remote possibility that the Internal Revenue Service (“IRS”) could issue guidance contrary to such treatment with respect to foreign currency gains that are not directly related to a RIC’s principal business of investing in stocks or securities (or options or futures with respect to stocks or securities), which could affect a Fund’s ability to meet the 90% gross income test and adversely affect the manner in which that Fund is managed.

•   Any distributions from income or short-term capital gains that you receive generally are taxable to you as ordinary dividends for federal income tax purposes. Ordinary dividends you receive that a Fund reports as “qualified dividend income” may be taxed at the same rates as long-term capital gains, but will not be considered long-term capital gains for other federal income tax purposes, including the calculation of net capital losses.

The validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[28][31] Each block typically contains a hash pointer as a link to a previous block,[31] a timestamp and transaction data.[32] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[33] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
The Morningstar Alternatives Solution ETF pays ProShare Advisors a fee at an annualized rate based on its average daily net assets of 0.07%. ProShare Advisors has entered into an Advisory and Management Services Fee Waiver Agreement that waives this investment advisory fee for the Morningstar Alternatives Solution ETF through at least October 31, 2018. Prior to this date, ProShare Advisors may not terminate the arrangement without the approval of the Board.
Bitcoin futures contracts are a new type of futures contract that began trading in December 2017. Unlike the established futures markets for traditional physical commodities, the market for bitcoin futures contracts is in the developmental stage and has very limited volume, trading and operational history. Bitcoin and other cryptocurrencies are a new and developing asset class subject to both developmental and regulatory uncertainty. Ownership of bitcoin is thought to be very concentrated and the supply and liquidity of bitcoin is limited. The price of bitcoin could drop precipitously for a variety of reasons including but not limited to regulatory changes, a crisis of confidence in the bitcoin network or a change in user preference to competing cryptocurrencies. As such, bitcoin futures contracts and the market for bitcoin futures contracts may be riskier, less liquid, more volatile and more vulnerable to economic, market, industry, regulatory and other changes than more established futures contracts and futures markets. There is no assurance that a liquid market will emerge or be sustained for bitcoin futures contracts. The liquidity of the market for bitcoin futures contracts will depend on, among other things, the supply and demand for bitcoin futures contracts, the adoption of bitcoin and the commercial and speculative interest in the market for bitcoin futures contracts. The price of bitcoin has been subject to periods of sudden and high volatility and, as a result, the price of bitcoin futures contracts also may experience periods of sudden and high volatility. Margin requirements for bitcoin futures contracts currently are, and may continue to be, materially higher than the typical margin requirements for more established types of futures contracts. Each of these factors could have a negative impact on the performance of the Fund and the market for Fund shares.
Subject to the general supervision by the Board, the Advisor is responsible for decisions to buy and sell securities and derivatives for each of the Funds and the selection of brokers and dealers to effect transactions. Purchases from dealers serving as market makers may include a dealer’s mark-up or reflect a dealer’s mark-down. Purchases and sales of U.S. government securities are normally transacted through issuers, underwriters or major dealers in U.S. government securities acting as principals. Such transactions, along with other fixed income securities transactions, are made on a net basis and do not typically involve payment of brokerage commissions. The cost of securities purchased from an underwriter usually includes a commission paid by the issuer to the underwriters; transactions with dealers normally reflect the spread between bid and asked prices; and transactions involving baskets of equity securities typically include brokerage commissions. As an alternative to directly purchasing securities, the Advisor may find efficiencies and cost savings by purchasing futures or using other derivative instruments like total return swaps or forward contracts. The Advisor may also choose to cross -trade securities between clients to save costs where allowed under applicable law.
Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s
ProShares Ultra, Short and UltraShort FTSE China 50 and ProShares Ultra and UltraShort FTSE Developed Europe are not in any way sponsored, endorsed, sold or promoted by FTSE International Limited (“FTSE”) or by the London Stock Exchange Group Companies (“LSEG”) (together the “Licensor Parties”) and none of the Licensor Parties make any claim, prediction, warranty or representation whatsoever, expressly or impliedly, either as to the (i) results to be obtained from the use of the FTSE China 50 Index
The NAV of each Fund is typically determined each business day at 3:00 p.m., Eastern Time on days when                    is open for trading. The [            ] Exchange is open every week, Monday through Friday, except when the following holidays are celebrated: New Year’s Day, Martin Luther King, Jr. Day (the third Monday in January), Presidents’ Day (the third Monday in February), Good Friday, Memorial Day (the last Monday in May), Independence Day, Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in November) and Christmas Day. An Exchange may close early on the business day before each of these holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If the exchange or market on which a Fund’s investments are primarily traded closes early, the NAV may be calculated prior to its normal calculation time. Creation/ redemption transaction order time cutoffs would also be accelerated.
To purchase or redeem through the Clearing Process, an Authorized Participant must be a member of NSCC that is eligible to use the Continuous Net Settlement system. For purchase orders placed through the Clearing Process, the Authorized Participant Agreement authorizes the Distributor to transmit through the Funds’ transfer agent (the “Transfer Agent”) to NSCC, on behalf of an Authorized Participant, such trade instructions as are necessary to effect the Authorized Participant’s purchase order. Pursuant to such trade instructions to NSCC, the Authorized Participant agrees to deliver the requisite Deposit Securities and the Balancing Amount to the Trust, together with the Transaction Fee and such additional information as may be required by the Distributor.
There is no registry showing which individuals or entities own bitcoin or the quantity of bitcoin that is owned by any particular person or entity. It is possible, and in fact, reasonably likely, that a small group of early bitcoin adopters hold a significant proportion of the bitcoin that has been thus far created. There are no regulations in place that would prevent a large holder of bitcoin from selling their bitcoin, which could depress the price of bitcoin and have an adverse effect on an investment in the Funds which do not take a short position in bitcoin futures contracts.
A Precautionary Note Regarding Unusual Circumstances — ProShares Trust can postpone payment of redemption proceeds for any period during which (1) [the Exchange] is closed other than customary weekend and holiday closings, (2) trading on [the Exchange] is restricted, (3) any emergency circumstances exist, as determined by the SEC, and (4) the SEC by order permits for the protection of shareholders of the Fund, as further described in the SAI.
There are two "types" of bitcoin -- Quanto and Inverse. Vast majority of bitcoin futures contracts are INVERSE, not Quanto. This means that the PNL is smoothed in USD terms, so that the contract value is maintained through price fluctuations. Put simply, it allows you to make a perfect USD-value hedge when you short with Bitcoin, which makes it ideal for speculators and hedgers. This means that if the BTC/USD value drops 1% you will earn more raw BTC than if it increases 1%. This is because when the price is falling, the USD value of the BTC is also falling, so the payout mathematically adjusts for this and increases as the price falls, compensating for the reduced USD value.
JUNK BONDS. “Junk Bonds” generally offer a higher current yield than that available for higher-grade issues. However, lower-rated securities involve higher risks, in that they are especially subject to adverse changes in general economic conditions and in the industries in which the issuers are engaged, to changes in the financial condition of the issuers and to price fluctuations in response to changes in interest rates. During periods of economic downturn or rising interest rates, highly leveraged issuers may experience financial stress that could adversely affect their ability to make payments of interest and principal and increase the possibility of default. In addition, the market for lower-rated debt securities has expanded rapidly in recent years, and its growth paralleled a long economic expansion. At times in recent years, the prices of many lower-rated debt securities declined substantially, reflecting an expectation that many issuers of such securities might experience financial difficulties. As a result, the yields on lower-rated debt securities rose dramatically, but the higher yields did not reflect the value of the income stream that holders of such securities expected. Rather, the risk that holders of such securities could lose a substantial portion of their value as a result of the issuers’ financial restructuring or default. There can be no assurance that such declines will not recur. The market for lower-rated debt issues generally is thinner and less active than that for higher quality securities, which may limit each Fund’s ability to sell such securities at fair value in response to changes in the economy or financial markets. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may also decrease the values and liquidity of lower-rated securities, especially in a thinly traded market. Changes by recognized rating services in their rating of a fixed income security may affect the value of these investments. Each Fund will not necessarily dispose of a security when its rating is reduced below the rating it had at the time of purchase. However, the Advisor will monitor the investment to determine whether continued investment in the security will assist in meeting each Fund’s investment objective.
The Funds may enter into swap agreements to gain exposure to an underlying asset without actually purchasing such asset, or to hedge a position including in circumstances in which direct investment is restricted for legal reasons or is otherwise impracticable. Swap agreements are two-party contracts entered into primarily by institutional investors for periods ranging from a day to more than one year. In a standard “swap” transaction, two parties agree to exchange the returns (or differentials in rates of return) earned or realized on a particular pre-determined investment or instrument. The gross return to be exchanged or “swapped” between the parties is calculated with respect to a “notional amount,” e.g., the return on or increase in value of a particular dollar amount invested in a “basket” of securities or an ETF representing a particular index or group of securities.

Each Fund may invest in master limited partnerships (“MLPs”), which are commonly treated as partnerships for U.S. federal income tax purposes and publicly traded on national securities exchanges. Such MLPs are limited by the Internal Revenue Code to apply to enterprises that engage in certain businesses, mostly pertaining to the use of natural resources, such as natural gas extraction and transportation. Some real estate enterprises may also qualify as MLPs.

Nelson Peltz of Trian Fund Management waged a proxy fight to get himself on the board of Procter & Gamble Co. that ended at P&G's annual meeting in October, when Peltz lost out to management nominee Ernesto Zedillo by about 6.2 million votes. Or did he? In November, an independent recount of the votes found that Peltz had beaten Zedillo by 42,780 votes, or about 0.0016 percent of the shares outstanding. Or did he? On Friday the final official count of the votes came in, finding that Zedillo actually won by 498,312 votes, or about 0.019 percent of the shares outstanding. It is a little disappointing that Zedillo's margin in the third count, though less than his margin in the first count, was bigger than Peltz's margin in the second. I was hoping that not only would the victor alternate with each count, but also that the margin would get narrower and narrower, until eventually we'd find out that the two sides were exactly tied except for a single ballot for a single share written in a special ink that says "Peltz" under fluorescent light and "Zedillo" under natural light. I was hoping that P&G would count the votes again and again forever.
In contrast, if you are “going short” on Bitcoin, you assume that Bitcoin prices will fall. Buying put options will enable you to sell Bitcoin at some point in the future at a price that is higher than the future price you expect. In analogy to the example above, if the current Bitcoin price is 5,000 USD and you expect it to fall to 2,000 USD in 6 months, then put options allowing you to sell Bitcoin for 5,000 USD in 5 months (when everyone else is selling for 2000 USD) are very valuable.
