Under Delaware law, the Trust is not required to hold an annual shareholders meeting if the 1940 Act does not require such a meeting. Generally, there will not be annual meetings of Trust shareholders. Trust shareholders may remove Trustees from office by votes cast at a meeting of Trust shareholders or by written consent. If requested by shareholders of at least 10% of the outstanding Shares of the Trust, the Trust will call a meeting of Funds’ shareholders for the purpose of voting upon the question of removal of a Trustee of the Trust and will assist in communications with other Trust shareholders.

To assist the Advisor in its responsibility for voting proxies and the overall proxy voting process, the Advisor has retained Institutional Shareholder Services (“ISS”) as an expert in the proxy voting and corporate governance area. ISS is a subsidiary of Vestar Capital Partners VI, L.P., a leading U.S. middle market private equity firm specializing in management buyouts and growth capital investments. The services provided by ISS include in-depth research, global issuer analysis and voting recommendations as well as vote execution, reporting and record keeping. ISS issues quarterly reports for the Advisor to review to assure proxies are being voted properly. The Advisor and ISS also perform spot checks intra-quarter to match the voting activity with available shareholder meeting information. ISS’s management meets on a regular basis to discuss its approach to new developments and amendments to existing policies. Information on such developments or amendments in turn is provided to the Proxy Committee. The Proxy Committee reviews and, as necessary, may amend periodically the Guidelines to address new or revised proxy voting policies or procedures.

The Trust, the Advisor and the Distributor each have adopted a consolidated code of ethics (the “COE”), under Rule 17j-1 of the 1940 Act, which is reasonably designed to ensure that all acts, practices and courses of business engaged in by personnel of the Trust, the Advisor and the Distributor reflect high standards of conduct and comply with the requirements of the federal securities laws. There can be no assurance that the COE will be effective in preventing deceptive, manipulative or fraudulent activities. The COE permits personnel subject to it to invest in securities, including securities that may be held or purchased by a Fund; however, such transactions are reported on a regular basis. The Advisor’s personnel that are Access Persons, as the term is defined in the COE, subject to the COE are also required to report transactions in registered open-end investment companies advised or sub-advised by the Advisor. The COE is on file with the SEC and is available to the public.
Portfolio holdings information may not be provided prior to its public availability (“Non-Standard Disclosure”) in other circumstances except where appropriate confidentiality arrangements limiting the use of such information are in effect. Non-Standard Disclosure may be authorized by the Trust’s CCO or, in his absence, any other authorized officer of the Trust if he determines that such disclosure is in the best interests of the Fund’s shareholders, no conflict exists between the interests of the Fund’s shareholders and those of the Advisor or Distributor and such disclosure serves a legitimate business purpose, and measures discussed in the previous paragraph regarding confidentiality are satisfied. The lag time between the date of the information and the date on which the information is disclosed shall be determined by the officer authorizing the disclosure. The CCO is responsible for ensuring that portfolio holdings disclosures are made in accordance with this Policy.
ProShare Advisors, from its own resources, including profits from advisory fees received from the Funds, also may make payments to broker-dealers and other financial institutions for their services and expenses incurred in connection with the distribution and promotion of the Funds’ Shares. In this regard, the Advisor or an affiliate of the Advisor, may directly or indirectly make cash payments to certain broker-dealers for participating in activities that are designed to make registered representatives and other professionals more knowledgeable about exchange traded products, including the Funds, or for other activities, such as participation in marketing activities and presentations, educational training programs, conferences, the development of technology platforms and
The CME Bitcoin futures contracts will be cash-settled, meaning that you will receive USD on the expiration date if your speculation was successful and you have not sold the derivative before the expiration date. You will not receive Bitcoin – that would be a physical settlement, even though Bitcoin is not a physical asset. This is a crucial difference because it enables traders to trade in Bitcoin futures without having a cryptocurrency wallet. Every transaction is done in USD.Thus, it is easy for mainstream traders to take part in this market.
There are dozens, if not hundreds, of unregulated online exchanges and brokerage firms offering cryptocurrencies and cryptocurrency trading products. Investors should be wary of too-good-to-be-true promotions and promises of quick riches. Once you deposit money, many of these firms will charge you outrageous commissions or make it very difficult to withdraw funds. Some of the worst offenders will simply steal your money.
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.
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).
•   Early Close/Late Close/Trading Halt Risk — An exchange or market may close early, close late or issue trading halts on specific securities, or the ability to trade certain securities or financial instruments may be restricted, which may disrupt the Fund’s creation and redemption process, potentially affect the price at which the Fund’s shares trade in the secondary market, and/or result in the Fund being unable to trade certain securities or financial instruments. In these circumstances, the Fund may be unable to rebalance its portfolio, may be unable to accurately price its investments and/or may incur substantial trading losses. If trading in the Fund’s shares halt, shareholders may be temporarily unable to trade shares of the Fund at an advantageous time or price.
Yields on U.S. government securities depend on a variety of factors, including the general conditions of the money and bond markets, the size of a particular offering, and the maturity of the obligation. Debt securities with longer maturities tend to produce higher yields and are generally subject to potentially greater capital appreciation and depreciation than obligations with shorter maturities and lower yields. The market value of U.S. government securities generally varies inversely with changes in market interest rates. An increase in interest rates, therefore, would generally reduce the market value of a Fund’s portfolio investments in U.S. government securities, while a decline in interest rates would generally increase the market value of a Fund’s portfolio investments in these securities.

The fund performance for a Geared ProShares Fund can be estimated given any set of assumptions for the factors described above. The tables on the next five pages illustrate the impact of two factors, benchmark volatility and benchmark performance, on a Geared Fund. Benchmark volatility is a statistical measure of the magnitude of fluctuations in the returns of a benchmark and is calculated as the standard deviation of the natural logarithm of one plus the benchmark return (calculated daily), multiplied by the square root of the number of trading days per year (assumed to be 252). The tables show estimated Fund returns for a number of combinations of benchmark performance and benchmark volatility over a one-year period. Assumptions used in the tables include: (a) no dividends paid with respect to securities included in the underlying benchmark; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leverage or inverse exposure) of zero percent. If Fund expenses and/or actual borrowing lending rates were reflected, the Fund’s performance would be different than shown.
For purposes of this SAI, the word “invest” refers to a Fund directly and indirectly investing in securities or other instruments. Similarly, when used in this SAI, the word “investment” refers to a Fund’s direct and indirect investments in securities and other instruments. For example, the Funds typically invest indirectly in securities or instruments by using financial instruments with economic exposure similar to those securities or instruments.
Words of caution are appropriate when talking about going short and using leverage. These strategies are incredibly effective because they allow investors to not only profit from a general upward trend in bitcoin but to profit from the fluctuations in the market. At first, it is hard to think of a more perfect asset than bitcoin for such purposes. The upward trends have been fast and extreme, yet fluctuations are very common and tend to be substantial.
Securities (including short-term securities) and other assets are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. Futures contracts and options on securities, indexes and futures contracts are generally valued at their last sale price prior to the time at which the NAV per share of a class of shares of a Fund is determined. Alternatively, fair valuation procedures as described below may be applied if deemed more appropriate. Routine valuation of certain other derivatives is performed using procedures approved by the Board of Trustees.

risk of loss of the amount expected to be received under a swap agreement in the event of the default or bankruptcy of a swap agreement counterparty. If such a default occurs, a Fund will have contractual remedies pursuant to the swap agreements, but such remedies may be subject to bankruptcy and insolvency laws that could affect the Fund’s right as a creditor. The counterparty risk for cleared swaps is generally lower than for uncleared over-the-counter swaps because generally a clearing organization becomes substituted for each counterparty to a cleared swap agreement and, in effect, guarantees the parties’ performance under the contract as each party to a trade looks only to the clearing organization for performance of financial obligations. However, there can be no assurance that the clearing organization, or its members, will satisfy its obligations to a Fund. Upon entering into a cleared swap, a Fund may be required to deposit with the broker an amount of cash or cash equivalents in the range of approximately 3% to 6% of the notional amount for CDS on high yield debt issuers and 1% to 5% for CDS on investment grade debt issuers (this amount is subject to change by the clearing organization that clears the trade). This amount, known as “initial margin,” is in the nature of a performance bond or good faith deposit on the cleared swap and is returned to a Fund upon termination of the swap, assuming all contractual obligations have been satisfied. Subsequent payments, known as “variation margin” to and from the broker will be made daily as the price of the swap fluctuates, making the long and short position in the swap contract more or less valuable, a process known as “marking-to-market.” The premium (discount) payments are built into the daily price of the swap and thus are amortized through the variation margin. The variation margin payment also includes the daily portion of the periodic payment stream.

Most cryptocurrencies are designed to gradually decrease production of that currency, placing a cap on the total amount of that currency that will ever be in circulation.[30] Compared with ordinary currencies held by financial institutions or kept as cash on hand, cryptocurrencies can be more difficult for seizure by law enforcement.[1] This difficulty is derived from leveraging cryptographic technologies.
A Fund will incur a loss as a result of a short sale if the price of the security increases between the date of the short sale and the date on which the Fund replaces the borrowed security. A Fund will realize a gain if the price of the security declines in price between those dates. The amount of any gain will be decreased, and the amount of any loss will be increased, by the amount of the premium, dividends or interest a Fund may be required to pay, if any, in connection with a short sale.
the Merrill Lynch Factor Model – Exchange Series benchmark). The Short ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Short”, “UltraShort” or “UltraPro Short” in their names, except for the Short Bitcoin Futures Strategy ETF) are designed to correspond to the inverse of the daily performance or an inverse multiple of the daily performance of an index. The Ultra ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Ultra” or UltraPro” in their names) are designed to correspond to a multiple of the daily performance of an index. The Funds, except the Matching ProShares Funds, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF, do not seek to achieve their stated investment objective over a period of time greater than a single day. A “single day” is measured from the time the Fund calculates its net asset value (“NAV”) to the time of the Fund’s next NAV calculation. Each Matching ProShares Fund, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF seeks to achieve its stated investment objective both on a single day and over time. The Managed Futures Strategy ETF is actively managed and seeks to provide positive returns that are not directly correlated to broad equity or fixed income markets. The Crude Oil Strategy ETF is actively managed and seeks to provide exposure to the West Texas Intermediate crude oil futures markets. The CDS Short North American HY Credit ETF is actively managed and seeks to provide short exposure to the credit of debt issuers. The Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and bitcoin futures contracts. The Short Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and short exposure to bitcoin futures contracts. The Bitcoin Futures/Equity Strategy ETF is actively managed and seeks total return through investment in U.S. equity securities and bitcoin futures contracts. The Blockchain/Bitcoin Strategy ETF is actively managed and seeks total return through investment in the equity securities of blockchain technology companies and exposure to bitcoin investments.
The Trust and the fund have obtained an exemptive order from the SEC allowing a registered investment company to invest in the Fund’s shares beyond the limits of Section 12(d)(1) subject to certain conditions, including that a registered investment company enters into a Participation Agreement with the Trust regarding the terms of the investment. Any investment company considering purchasing shares of the Fund in amounts that would cause it to exceed the restrictions of Section 12(d)(1) should contact the Trust.
that receive different proportions of the interest and principal distributions from a pool of mortgage assets. The Funds will only invest in SMBS whose mortgage assets are U.S. government obligations. A common type of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage assets, while the other class receives most of the interest and the remainder of the principal. If the underlying mortgage assets experience greater than anticipated prepayments of principal, each Fund may fail to fully recoup its initial investment in these securities. The market value of any class that consists primarily or entirely of principal payments generally is unusually volatile in response to changes in interest rates.
Cryptocurrencies allow traders to diversify their investment portfolio, as their price is mainly determined by demand and supply; Their value has a low correlation to national economies or political scenarios. Once Bitcoin surpassed the price of gold in 2017, US markets introduced 2 ETFs on Bitcoin and drew more and more institutional money into the world of cryptocurrencies. In 2017, Indian PM Narendra Modi has announced the gradual replacement of paper currency with electronic currency; In March 2018, the Marshall Islands announced that they would be introducing a cryptocurrency to replace US dollars as their main currency; other central banks are investigating the adoption of blockchain-like technologies… in short cryptocurrencies are probably here to stay. A growing number of crypto investors all over the world have already discovered the benefits:

On top of that, the cryptocurrency market travels at lightspeed compared to other markets. New coins enter the market on a daily basis (in 2016, there were about 550 different coins, today there are about 1,500), and each one has news every day. I’m not doubting your ability to consume and analyze news, but that level of information bombardment will always be more effectively consumed as a group. In these communities, you’ll see members link news and relevant articles about coins you’ve invested in and coins you’ve never heard of. The community will definitely expand your knowledge much faster than doing it all yourself.

  •   A new competing digital asset may pose a challenge to bitcoin’s current market dominance, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin. It is possible that other digital currencies and trading systems could become more widely accepted and used than bitcoin. The rise of such currencies could lead to a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin.

Distributions of Shares shall be made to DTC or its nominee, Cede & Co., as the registered holder of all Shares. DTC or its nominee, upon receipt of any such distributions, shall credit immediately DTC Participants’ accounts with payments in amounts proportionate to their respective beneficial interests in Shares as shown on the records of DTC or its nominee. Payments by DTC Participants to Indirect Participants and Beneficial owners of Shares held through such DTC Participants will be governed by standing instructions and customary practices, as is now the case with securities held for the accounts of customers in bearer form or registered in a “street name,” and will be the responsibility of such DTC Participants. The Trust has no responsibility or liability for any aspects of the records relating to or notices to Beneficial owners, or payments made on account of beneficial ownership interests in such Shares, or for maintaining, supervising or reviewing any records relating to such beneficial ownership interests or for any other aspect of the relationship between DTC and the DTC Participants or the relationship between such DTC Participants and the Indirect Participants and Beneficial owners owning through such DTC Participants.
Bitcoin Gold (BTG) is the second fork from Bitcoin (i.e. the second version to stem from Bitcoin’s source code). It retains Bitcoin’s transaction history, meaning that if you owned Bitcoin before the fork, you now own the equal amount of Bitcoin Gold. This cryptocurrency aims to introduce an alternative mining algorithm that is less susceptible to ASIC-based optimization, therefore allowing users to earn more with their computer cycles.

In general, a beneficial owner of Fund Shares who or which is a foreign shareholder is not subject to U.S. federal income tax on gains (and is not allowed a deduction for losses) realized on a sale of shares of the Fund unless (i) such gain effectively connected with the conduct of a trade or business carried on by such holder within the United States, (ii) in the case of an individual holder, the holder is present in the United States for a period or periods aggregating 183 days or more during the year of the sale or and certain other conditions are met, or (iii) the special rules relating to gain attributable to the sale or exchange of “U.S. real property interests” (“USRPIs”) apply to the foreign shareholder’s sale of shares of the Fund (as described below).
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.
A Bitcoin (spot or futures) exchange (like any online trading firm) charges its clients a fee to carry out trading activities. As exchanges face the risk of hacking and theft, it is wise not to trust an exchange with all your coins. You should split and keep part of them in other devices or cold storage. Now with bitcoin futures being offered by some of the most prominent marketplaces, investors, traders and speculators are all bound to benefit. These centralized marketplaces will facilitate trade based on a trader’s outlook for bitcoin prices, gain exposure to bitcoin prices or hedge their existing bitcoin positions. Overall, the launching of bitcoin futures by Cboe and CME will facilitate price discovery and price transparency, enable risk-management via a regulated bitcoin product and give a further push to bitcoin as an accepted asset class. (For more, see: The Risks Of Buying Bitcoins.)

In order to provide current Share pricing information, an Exchange disseminates an updated Indicative Optimized Portfolio Value (“IOPV”) for each Fund. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no warranty as to the accuracy of the IOPVs. IOPVs are expected to be disseminated on a per Fund basis every 15 seconds during regular trading hours of an Exchange.
Options involve risk and are not suitable for all investors. Prior to buying or selling an option, a person must receive a copy of Characteristics and Risks of Standardized Options (ODD).

The exceptions to withholding for Capital Gain Dividends and short-term capital gain dividends do not apply to (A) distributions to an individual foreign shareholder who is present in the United States for a period or periods aggregating 183 days or more during the year of the distribution and (B) distributions attributable to gain that is treated as effectively connected with the conduct by the foreign shareholder of a trade or business within the United States under special rules regarding the disposition of U.S. real property interests as described below. The exception to withholding for interest-related dividends does not apply to distributions to a foreign shareholder (A) that has not provided a satisfactory statement that the beneficial owner is not a U.S. person, (B) to the extent that the dividend is attributable to certain interest on an obligation if the foreign shareholder is the issuer or is a 10% shareholder of the issuer, (C) that is within certain foreign countries that have inadequate information exchange with the United States, or (D) to the extent the dividend is attributable to interest paid by a person that is a related person of the foreign shareholder and the foreign shareholder is a controlled foreign corporation. If a Fund invests in a RIC that pays Capital Gain Dividends, short-term capital gain dividends or interest-related dividends to the Fund, such distributions retain their character as not subject to withholding if properly reported when paid by the Fund to foreign shareholders. A Fund is permitted to report such part of its dividends as interest-related and/or short-term capital gain dividends as are eligible, but is not required to do so.

The Declaration of Trust of the Trust disclaims liability of the shareholders or the Officers of the Trust for acts or obligations of the Trust which are binding only on the assets and property of the Trust. The Declaration of Trust provides for indemnification of the Trust’s property for all loss and expense of any Funds shareholder held personally liable for the obligations of the Trust. The risk of a Trust shareholder incurring financial loss on account of shareholder liability is limited to circumstances where the Funds would not be able to meet the Trust’s obligations and this risk, thus, should be considered remote.

The table below shows a performance example of a Short ProShares Fund that has an investment objective to correspond to the inverse (-1x) of the daily performance of an index. In the chart below, areas shaded lighter represent those scenarios where a Short ProShares Fund will return the same or outperform (i.e., return more than) the index performance; conversely, areas shaded darker represent those scenarios where a Short ProShares Fund will underperform (i.e., return less than) the index performance.

Given the economic and environmental concerns associated with mining, various "minerless" cryptocurrencies are undergoing active development.[40][41] Unlike conventional blockchains, some directed acyclic graph cryptocurrencies utilise a pay-it-forward system, whereby each account performs minimally heavy computations on two previous transactions to verify. Other cryptocurrencies like Nano utilise a block-lattice structure whereby each individual account has its own blockchain. With each account controlling its own transactions, no traditional proof-of-work mining is required, allowing for feeless, instantaneous transactions.[42][better source needed]
•   Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.
The first thing you need to get started trading bitcoin is to open a bitcoin wallet. If you do not have a bitcoin wallet then you can open one at the biggest wallet called coinbase.  We have arranged a special deal for everyone wanting to get started in bitcoin to get a free $10 at coinbase. Get your free $10 by opening your coinbase account here.
•   Daily Position Limit Risk - Many U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the trading day. In addition, these exchanges have established limits on the maximum amount of futures positions that any person may hold or control on such exchanges. These limits may restrict the amount of assets the Fund is able to invest in bitcoin futures contracts or have a negative impact on the price of such contracts. In order to comply with such limits, the Fund may be required to reduce the size of its outstanding positions or not enter into new positions that would otherwise be taken for the Fund. This could potentially subject the Funds to substantial losses or periods in which the Fund does not accept additional Creation Units.
​Trading these futures instead of actual bitcoins is smart because you are able to access higher leverage by entering contracts with counterparties, while keeping your coins safe in cold storage or elsewhere. Additionally, unlike trading margin on Kraken or Bitfinex, you do NOT have to pay interest on the leverage you have! This is the result of the counterparty structure of futures. High leverage trading, low-fees, and high profit potential.
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. 
This may sound like an unfair system to those who are used to trading with confidence that their profits are settled in full, but it's a compromise that has been made in order to offer the high leverage. If you want to guarantee that your profits are not reduced by any socialised loss, then use CryptoFacilities or Coinpit. They use a "termination" procedure in the event of a margin call not being filled. This simply terminates the contract and sends the portfolio value of the losing counterparty to the winning counterparty. It's worth noting that the system has been incredibly robust, with very minimal socialised losses being triggered on OKCoin and none on BitMEX as of November 2015.
On May 7, 2014, the SEC published an investor alert that highlighted fraud and other concerns relating to certain investment opportunities denominated in bitcoin and fraudulent and unregistered investment schemes targeted at participants in online bitcoin forums. On July 25, 2017, the SEC issued a Report of Investigation or Report which concluded that digital assets or tokens issued for the purpose of raising funds may be securities within the meaning of the federal securities laws. The Report emphasized that whether a digital asset is a security is based on the particular facts and circumstances, including the economic realities of the transactions. This was reiterated in a December 11, 2017 Public Statement emphasizing the risks of investing in digital assets such as bitcoin and noting the possibility that bitcoin and other digital assets may be deemed to be securities. The SEC continues to take action against persons or entities misusing bitcoin in connection with fraudulent schemes (i.e., Ponzi scheme), inaccurate and inadequate publicly disseminated information, and the offering of unregistered securities.
This material has been prepared by a Daniels Trading broker who provides research market commentary and trade recommendations as part of his or her solicitation for accounts and solicitation for trades; however, Daniels Trading does not maintain a research department as defined in CFTC Rule 1.71. Daniels Trading, its principals, brokers and employees may trade in derivatives for their own accounts or for the accounts of others. Due to various factors (such as risk tolerance, margin requirements, trading objectives, short term vs. long term strategies, technical vs. fundamental market analysis, and other factors) such trading may result in the initiation or liquidation of positions that are different from or contrary to the opinions and recommendations contained therein.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
Altcoins is the general term associated with the cryptocurrencies launched after Bitcoin’s success. At first, these were mere copies mimicking the original Bitcoin. Today, there are over 1,000 of these, and the list just keeps growing. Most crypto coins are launched following an ICO (Initial Coin Offering – a form of crowdfunding) in which the developers raise cash by offering a limited number of initial coins to finance technological development. So far, besides the list below, we can find names, such as Namecoin, Peercoin, Bytecoin, Deutsche eMark, Novacoin, Cryptogenic Bullion, Quark, DarkCoin and Mangocoinz (for smartphones).
If anything, the problem seems to start with incredibly lax risk management at this exchange.  According to the OKEX statement, the risk management team 'immediately' contacted the client to reduce the size of the trade - begging the question - how did their risk management system allow the trade to occur in the first place?  On the bright side, something like that should be easy to fix, but it is indicative, potentially of how many simple things are being overlooked in the rush to make money from crypto trading.
  •   Risks Associated with Bitcoin – The Fund is exposed to risks associated with bitcoin. Investing in or gaining exposure to Bitcoin may provide the Fund with increased risk. Various global factors may negatively impact the Fund’s performance including legal, regulatory, political, social, regional and economic events. These risks, which could have a negative impact on the performance of the Fund and the trading price of Fund shares, include the following:
This post-effective amendment relates only to ProShares Bitcoin Futures Strategy ETF, ProShares Short Bitcoin Futures Strategy ETF, ProShares Bitcoin Futures/Equity Strategy ETF and ProShares Bitcoin/Blockchain Strategy ETF, each a new series of ProShares Trust. No information relating to any other series or class of series of ProShares Trust is amended or superseded hereby.
FOREIGN SOVEREIGN, SUB-SOVEREIGN, QUASI SOVEREIGN AND SUPRANATIONAL SECURITIES. The Funds may invest in fixed-rate debt securities issued by: non-U.S. governments (foreign sovereign bonds); local governments, entities or agencies of a non-U.S. country (foreign sub-sovereign bonds); corporations with significant government ownership (“Quasi-Sovereigns”); or two or more central governments or institutions (supranational bonds). These types of debt securities are typically
The tables below shows performance examples of an Ultra and UltraShort ProShares Fund that have investment objective to correspond to two times (2x) and two times the inverse (-2x) of, respectively, the daily performance of an index. In the charts below, areas shaded lighter represent those scenarios where a Fund will return the same or outperform (i.e., return more than) the index performance times the stated multiple in the Fund’s investment objective; conversely areas shaded darker represent those scenarios where the Fund will underperform (i.e., return less than) the index performance times the stated multiple in the Fund’s investment objective.

Like all investments, investing in any of the Funds entails risks. The risk factors most likely to have a significant impact on a Fund’s portfolio are called “principal risks.” The principal risks of each Fund are described in the applicable Fund’s Summary Prospectus and additional information regarding certain of these principal risks, as well as information related to other potential risks to which a particular Fund may be subjected, is provided below. Some risks apply to all of the Funds, while others are specific to the investment strategies of certain Funds, as indicated below.

The foregoing discussion is primarily a summary of certain U.S. federal income tax consequences of investing in a Fund based on the law in effect as of the date of this SAI. The discussion does not address in detail special tax rules applicable to certain classes of investors, such as, among others, IRAs and other retirement plans, tax-exempt entities, foreign investors, insurance companies, banks and other financial institutions, and investors making in-kind contributions to a Fund. Such shareholders may be subject to U.S. tax rules that differ significantly from those summarized above. You should consult your tax advisor for more information about your own tax situation, including possible other federal, state, local and, where applicable, foreign tax consequences of investing in a Fund.

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.
