The Fund generally does not expect to invest directly in futures contracts, option contracts and swap agreements (“Bitcoin Instruments”). The Fund expects to gain exposure to these investments by investing a portion of its assets in the ProShares Cayman Short Bitcoin Futures Strategy Portfolio, a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The Subsidiary is advised by ProShare Advisors, the Fund’s investment advisor, and invests directly in Bitcoin Instruments. Unlike the Fund, the Subsidiary is not an investment company registered under the 1940 Act. The Fund’s investment in the Subsidiary is intended to provide the Fund with exposure to commodity markets related to bitcoin in accordance with applicable rules and regulations. The Fund will invest up to 25% of its total assets in the Subsidiary. Except as otherwise noted, references to the Fund’s investment strategies and risks include the investment strategies and risks of the Subsidiary.
Some Centra investors have their doubts, and a plaintiffs' law firm has brought a class action complaint against Centra demanding the investors' money back. The complaint is fun -- Centra had a “Blog/Media Bounty” program to "Reward Experienced Writers who write quality Reviews, Articles About the Centra Project and the ICO crowdsale" -- but not that fun, because the plaintiffs' lawyers don't actually need to prove that Centra was a scam. Their job is much easier: All they need to do is prove that the tokens Centra sold in its initial coin offering were securities. If they were securities, they were sold illegally: They were offered publicly without being registered with the Securities and Exchange Commission, or being exempt from registration. And one remedy for the illegal sale of securities is that the buyers can demand their money back -- whether or not Centra is legitimate, whether or not it is actually using the money to build a cryptocurrency debit card, whether or not it made any misleading statements in the ICO.

For each of the following Funds that hold Non-U.S. Investments: the DJ Brookfield Global Infrastructure ETF; the Global Listed Private Equity ETF; the MSCI EAFE Dividend Growers ETF; the MSCI Europe Dividend Growers; the Short Term USD Emerging Markets Bond ETF; and the Merger ETF (each a “Global Fund” and collectively the “Global Funds”), when a purchase order is placed, the Distributor will inform the Advisor and the Custodian. The Custodian shall cause local sub-custodians of the applicable Global Fund to maintain an account into which the Authorized Participant shall deliver, on behalf of itself or the party on whose behalf it is acting, the Deposit Securities “free of payment,” with any appropriate adjustments as advised by the Trust, in accordance with the terms and conditions applicable to such account in such jurisdiction. If applicable, the sub-custodian(s) will confirm to the Custodian that the required Deposit Securities have been delivered and the Custodian will notify the Advisor and Distributor. The Authorized Participant must also make available to the Custodian no later than 12:00 noon Eastern Time (or earlier in the event that the relevant Exchange or the relevant bond markets close early) by the second Business Day after the order is deemed received through the Federal Reserve Bank wire transfer system, immediately available or same day funds in U.S. dollars estimated by the Trust to be sufficient to pay the Balancing Amount next determined after acceptance of the purchase order, together with any applicable Transaction Fees. For Global Funds, the Index Receipt Agent will not make available through the NSCC on each Business Day, the list of the names and the required number of shares of each Deposit Security to be included in the current Portfolio Deposit.
Various government agencies, departments, and courts have classified bitcoin differently. China Central Bank banned the handling of bitcoins by financial institutions in China in early 2014.[69] In Russia, though cryptocurrencies are legal, it is illegal to actually purchase goods with any currency other than the Russian ruble.[70] Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[71]

The Funds are required to identify any securities of its “regular brokers and dealers” (as such term is defined in the 1940 Act) which they may hold at the close of their most recent fiscal year. “Regular brokers or dealers” of the Trust are the ten brokers or dealers that, during the most recent fiscal year: (i) received the greatest dollar amounts of brokerage commissions from the Trust’s portfolio transactions; (ii) engaged as principal in the largest dollar amounts of portfolio transactions of the Trust; or (iii) sold the largest dollar amounts of the Trust’s Shares. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on
RD – Restricted default. ‘RD’ ratings indicate an issuer that in Fitch’s opinion has experienced an uncured payment default on a bond, loan or other material financial obligation but which has not entered into bankruptcy filings, administration, receivership, liquidation or other formal winding-up procedure, and which has not otherwise ceased operating. This would include:
The DJ Brookfield Global Infrastructure ETF, the Global Listed Private Equity ETF, the Merger ETF, the MSCI EAFE Dividend Growers ETF, and the MSCI Europe Dividend Growers ETF contain portfolio investments that are primarily listed or traded on foreign markets. To the extent a Fund’s portfolio investments trade in foreign markets on days when a Fund is not open for business or when the primary exchange for the Shares is not open, the value of the Fund’s assets may vary and shareholders may not be able to purchase or sell Fund Shares and Authorized Participants may not be able to create or redeem Creation Units. Also, certain portfolio investments may not be traded on days a Fund is open for business.
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.

When the market for certain futures contracts is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the “rolling process” of the more nearby bitcoin futures contracts would take place at a price that is lower than the price of the more distant bitcoin futures contracts. This pattern of higher futures prices for longer expiration bitcoin futures contracts is often referred to as “contango.” Alternatively, when the market for certain bitcoin futures contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the “rolling process” of the more nearby bitcoin futures contracts would take place at a price that is higher than the price of the more distant bitcoin futures contracts. This pattern of higher future prices for shorter expiration bitcoin futures contracts is referred to as “backwardation.”
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.)

For hedging purposes, the Funds may invest in forward currency contracts to hedge either specific transactions (transaction hedging) or portfolio positions (position hedging). Transaction hedging is the purchase or sale of forward currency contracts with respect to specific receivables or payables of the Funds in connection with the purchase and sale of portfolio securities. Position hedging is the sale of a forward currency contract on a particular currency with respect to portfolio positions denominated or quoted in that currency.
If you want to do scalping, then shorter-term expiree contracts that settle really soon would be fine. Keep in mind, the normal state of futures markets is "contango", which means that longer dated contracts will have a premium to the current spot rate, to reflect the interest rate differential and time preference.  This means you will see Weeklies maybe with a $1-2 preium and Quarterlies (assuming they expire months from now) with a $5-8 premium.  As an example we have Quarterlies contracts right now at OKCoin that settle on December 25. So we're just starting December now, that means that even though these are "Quarterlies" contracts by classification, they are expiring not 3 months from now, but 1 month from now. Don't mix up the settlement expiration date with the naming convention. 
Orders to redeem Creation Units outside the Clearing Process (other than for Global Fund orders), including all cash-only redemptions, must be delivered through a DTC Participant that has executed the Authorized Participant Agreement. A DTC Participant who wishes to place an order for redemption of Creation Units to be effected outside the Clearing Process need not be a “participating party” under the Authorized Participant Agreement, but such orders must state that the DTC Participant is not using the Clearing Process and that the redemption of Creation Units will instead be effected through a transfer of Shares directly through DTC. A redemption order for a Fund must be received by the cut-off times set forth in “Redemption Cut-Off Times” above. The order must be accompanied or preceded by the requisite number of Shares of Funds specified in such order, which delivery must be made through DTC to the Custodian by the second Business Day (T+3) following such transmittal date. All other procedures set forth in the Authorized Participant Agreement must be properly followed in order to receive the next determined NAV.
through direct investments/short positions in the securities and/or through investments with similar economic characteristics. For the purposes of each such investment policy, “assets” includes a Fund’s net assets, as well as amounts borrowed for investment purposes, if any. In addition, for purposes of such an investment policy, “assets” includes not only the amount of a Fund’s net assets attributable to investments providing direct investment exposure to the type of investments suggested by its name (e.g., the value of stocks, or the value of derivative instruments such as futures, options or options on futures), but also cash and cash equivalents that are segregated on the Fund’s books and records or being used as collateral, as required by applicable regulatory guidance, or otherwise available to cover such investment exposure. The Board has adopted a policy to provide investors with at least 60 days’ notice prior to changes in a Fund’s name policy.
You may wonder: where do these contracts come from? We know on the spot market that bitcoins are being bought and sold for fiat, but how the heck are bitcoins being used to trade bitcoin futures contracts? Let's walk through a really simple example showing how an exchange functions when there's just a simple two traders who want to go long and short. 
The Advisor, with the assistance of ISS, maintains for a period of at least five years a record of each proxy statement received and materials that were considered when the proxy was voted during the calendar year.

•   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.


•   A Fund’s income from or the proceeds of dispositions of its non-U.S. investments may be subject to withholding and other taxes imposed by foreign countries, which will reduce the Fund’s return on and taxable distributions in respect of its non-U.S. investments. Tax conventions between certain countries and the United States may reduce or eliminate these taxes. If more than 50% of the value of a Fund’s total assets at the close of a taxable year consists of securities of foreign corporations, the Fund will be eligible to elect to “pass through” to you foreign income taxes that it has paid. If this election is made, you will be required to include your share of those taxes in gross income as a distribution from the Fund and you generally will be allowed to claim a credit (or a deduction, if you itemize deductions) for these amounts on your federal U.S. income tax return, subject to certain limitations.

The Registrant (also, the “Trust”) is organized as a Delaware business trust is operated pursuant to an Amended and Restated Declaration of Trust, dated December 13, 2010 (the “Declaration of Trust”), that permits the Registrant to indemnify every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof. This indemnification is subject to the following conditions:
Now, if that margin-call does not get filled and the price continues to fall, then I'm making profits on my contract but nobody is paying for it since the counterparty who got margin-called didn't get the liquidation order filled. So what happens is that at settlement time of the contract, that unfilled liquidation loss to the system will be deducted from the profits of ALL traders before they are distributed.
Each Fund intends to distribute its net investment income and capital gains to shareholders at least annually to qualify for treatment as a RIC under the Code. Under current law, provided a Fund is not treated as a “personal holding company” for U.S. federal income tax purposes, the Fund is permitted to treat on its tax return as dividends paid the portion of redemption proceeds paid to redeeming shareholders that represents the redeeming shareholders’ portion of the Fund’s accumulated earnings and profits. This practice, called tax “equalization,” reduces the amount of income and/or gains that a Fund is required to distribute as dividends to non-redeeming shareholders. Tax equalization is not available to a Fund treated as a personal holding company. The amount of any undistributed income and/or gains is reflected in the value of a Fund’s Shares. The total return on a shareholder’s investment will generally not be reduced as a result of a Fund’s use of this practice.
•	 	Counterparty Risk —The Fund bears the risk that the counterparty to derivative transaction, such as a futures contract, defaults or otherwise fails to honor its obligations. If a counterparty defaults, the Fund will lose money and the value of an investment in the Fund may decrease. The Fund may engage in futures transactions with a limited number of counterparties, which may increase the Fund’s exposure to counterparty risk. The effect of the volatility of bitcoin pricing or other aspects of trading in bitcoin futures on futures clearinghouses for bitcoin futures is currently unknown, and may result in increased counterparty risk.

As a general matter, the Short ProShares Funds, the CDS Short North American HY Credit ETF and the Short Bitcoin Futures Strategy ETF respond differently in response to market conditions than the Matching ProShares Funds, the Ultra ProShares Funds, the Managed Futures Strategy ETF or the Crude Oil Strategy ETF. The terms “favorable market conditions” and “adverse market conditions,” as used in this SAI, are Fund-specific.
In general, a foreign corporation that is not engaged in and is not treated as engaged in a U.S. trade or business is nonetheless subject to tax at a flat rate of 30% (or lower tax treaty rate), generally payable through withholding, on the gross amount of certain U.S.-source income that is not effectively connected with a U.S. trade or business. There is presently no tax treaty in force between the United States and the jurisdiction in which any Subsidiary is (or would be) resident that would reduce this rate of withholding tax. Income subject to such a flat tax is of a fixed or determinable annual or periodic nature and includes dividends and interest income. Certain types of income are specifically exempted from the 30% tax and thus withholding is not required on payments of such income to a foreign corporation. The 30% tax generally does not apply to capital gains (whether long-term or short-term) or to interest paid to a foreign corporation on its deposits with U.S. banks. The 30% tax also does not apply to interest which qualifies as “portfolio interest.” Very generally, the term portfolio interest includes U.S.-source interest (including OID) on an obligation in registered form, and with respect to which the person, who would otherwise be required to deduct and withhold the 30% tax, received the required statement that the beneficial owner of the obligation is not a U.S. person within the meaning of the Code.
Sections 1471-1474 of the Code and the U.S. Treasury and IRS guidance issued thereunder (collectively, “FATCA”) generally require a Fund to obtain information sufficient to identify the status of each of its shareholders under FATCA or under an applicable intergovernmental agreement (an “IGA”). If a shareholder fails to provide this information or otherwise fails to comply with FATCA or an IGA, a Fund or its agent may be required to withhold under FATCA at a rate of 30% with respect to that shareholder on ordinary dividends it pays to such shareholder and 30% of the gross proceeds of share redemptions or exchanges and certain Capital Gain Dividends it pays to such shareholder after December 31, 2018. If a payment by a Fund is subject to FATCA withholding, the Fund or its agent is required to withhold even if such payment would otherwise be exempt from withholding under the rules applicable to foreign shareholders described above (e.g., Capital Gain Dividends, short-term capital gain dividends, and interest-related dividends).
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. 
Oops! These guys seem to have had no background in cryptocurrency, which hurt them. If they had raised money from "donors" by selling tokens with no "rights, uses, purpose, attributes, functionalities or features," they'd be fine. But they were used to raising money from investors, so they called the people who bought their tokens "investors." It's a rookie crypto mistake, and one that might cost them all the money they raised.

Each Fund may provide redemptions in portfolio securities or cash at the Advisor’s discretion. With respect to the Matching and Ultra ProShares Funds, the Index Receipt Agent makes available through the NSCC immediately prior to the opening of business on the Exchange on each day that the Exchange is open for business the portfolio securities that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”). These securities, at times, may not be identical to Deposit Securities which are applicable to a purchase of Creation Units. The Fund may also, in its sole discretion, upon request of a shareholder, provide such redeeming shareholder a portfolio of securities which differs from the exact composition of the Fund Securities but does not differ in NAV.

Crypto derivatives were naturally discovered as an interesting addition to cryptocurrency exchanges first – probably as individual contracts between interested investors on these exchanges. Nowadays, there are already a couple of exchanges that offer crypto derivatives trading as a standard feature: BitMEX is the current market leader, according to The Merkle News; others are OKCoin, Crypto Facilities, Coinpit, and Deribit, as well as LedgerX (the first regulated cryptocurrency exchange in the US).
