•   Swap Agreements are agreements entered into primarily with major global financial institutions for a specified period ranging from a day to more than one year. In a standard “swap” transaction, two parties agree to exchange the return (or differentials in rates of return) earned or realized on particular predetermined investments or instruments.
Cryptocurrency is based on knowledge sharing on a distributed platform. The entire transactional history is for everyone to see. One blockchain is one thread of transaction. One unit or one block stores many transactions. The size of the block is 1MB and generally stores around 1000 to 2000 transactions. The data entered cannot be altered, nor can it be removed, enabling a system of complete transparency and trust. The entire money flow for the working model is beyond the traditional practices of controlling tax rates, credit usage, and money supply in the market.
  •   Futures Position Limit Risk — Limits on the amount of futures any one entity can hold may negatively impact the Fund’s ability to meet its investment objective if such limits are reached and exceptions to such limits are not granted. Currently the position limits for bitcoin futures contracts are much lower than they are for most other futures contracts.
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:

There are also purely technical elements to consider. For example, technological advancement in cryptocurrencies such as bitcoin result in high up-front costs to miners in the form of specialized hardware and software.[105] Cryptocurrency transactions are normally irreversible after a number of blocks confirm the transaction. Additionally, cryptocurrency can be permanently lost from local storage due to malware or data loss. This can also happen through the destruction of the physical media, effectively removing lost cryptocurrencies forever from their markets.[106]

  •   Inverse Correlation Risk — Since a portion of the Fund’s assets are invested in short positions in bitcoin futures contracts, the Fund will likely decline in value when the price of bitcoin futures contracts goes up (unless such losses are offset by gains in the value of the Fund’s positions in other investments), a result that is the opposite from the results of taking long positions in bitcoin futures contracts.
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.
Futures contracts expire on a designated date, referred to as the “expiration date.” Each Fund typically will invest in “lead month” contracts. Lead month contracts are the monthly contracts with the earliest expiration date. Bitcoin futures contracts listed on the CBOE Futures Exchange (“CFE”) or Chicago Mercantile Exchange (“CME”) will be cash settled on their expiration date unless they are “rolled” prior to expiration. Each Fund generally intends to “roll” its bitcoin futures contracts prior to expiration to the next “nearby” bitcoin futures contract. The “nearby” contracts are those contracts with the next closest expiration date. The Funds will incur the costs (or benefits) of continually rolling into the new lead month contracts.
The value of the bitcoin futures contracts is generally based on the expected value of bitcoin at a future point in time, specifically, the expiration date of the bitcoin futures contracts. Other factors, such as cost of mining, storing and securing bitcoin may affect the value of bitcoin futures. A change in the price of bitcoin today (sometimes referred to as the “spot” price) will not necessarily result in a corresponding movement in the price of the bitcoin futures contracts since the price of the bitcoin futures contracts is based on expectations of the price of bitcoin at a future point in time. Additionally, there is no one centralized source for pricing bitcoin and pricing from one bitcoin exchange to the next can vary widely. Therefore, the value of the bitcoin futures contracts held by the Fund should not be expected to track the price of bitcoin on the Bitcoin Exchange Market.
Maintenance Margin - this is the % of the position value you have to have in your account at the very minimum to avoid being Margin Called.  In some exchanges, margin call will mean you get notified and must deposit more margin to avoid liquidation (like CryptoFacilities). On other exchanges you will at this point be liquidated out of your position. So if maintenance margin is 5%, then the 0.05 BTC of your initial margin will need to be kept for the position to be alive.
Banks may not provide banking services, or may cut off banking services, to businesses that provide bitcoin-related services or that accept bitcoin as payment, which could damage the public perception of bitcoin and the utility of bitcoin as a payment system and could decrease the price of bitcoin and the Bitcoin Instruments and adversely affect an investment in the Funds.
The Funds may engage in short sales transactions. A short sale is a transaction in which a Fund sells a security it does not own in anticipation that the market price of that security will decline. To complete such a transaction, a Fund must borrow the security to make delivery to the buyer. The Fund is then obligated to replace the security borrowed by borrowing the same security from another lender, purchasing it at the market price at the time of replacement or paying the lender an amount equal to the cost of purchasing the security. The price at such time may be more or less than the price at which the security was sold by the Fund. Until the security is replaced, the Fund is required to repay the lender any dividends it receives, or interest which accrues, during the period of the loan. To borrow the security, the Fund also may be required to pay a premium, which would increase the cost of the security sold. The net proceeds of the short sale will be retained by the broker, to the extent necessary to meet the margin requirements, until the short position is closed out. A Fund also will incur transaction costs in effecting short sales.
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.
price of a particular asset, whether a Fund will realize a gain or loss from the purchase or writing (sale) of options on an index depends upon movements in the level of prices for specific underlying assets generally or, in the case of certain indexes, in an industry or market segment. A Fund will not enter into an option position that exposes the Fund to an obligation to another party, unless the Fund either (i) owns an offsetting position in the underlying securities or other options and/or (ii) earmarks or segregates with the Fund’s custodian bank cash or liquid instruments that, when added to the premiums deposited with respect to the option, are equal to the market value of the underlying assets not otherwise covered.

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.

of the calendar year, and (3) all such ordinary income and capital gains that were not distributed in previous years. For purposes of the required excise tax distribution, ordinary gains and losses from the sale, exchange, or other taxable disposition of property that would be properly taken into account after October 31 are generally treated as arising on January 1 of the following calendar year. Also, for these purposes, the Fund will be treated as having distributed any amount on which it is subject to corporate income tax for the taxable year ending within the calendar year. The Funds intend generally to make distributions sufficient to avoid imposition of the excise tax, although the Funds reserve the right to pay an excise tax rather than make an additional distribution when circumstances warrant (for example, the payment of the excise tax amount is deemed to be de minimis).
Trader A is a producer of pork bellies. In order to insure herself against a price drop in pork bellies in the future, she enters a futures contract with Trader B. Trader B uses these pork bellies to manufacture sliced breakfast bacon. Thus, he is not worried that prices might fall in the future – his worry is that prices will go up. Both traders agree that Trader A will sell a metric ton of pork bellies for 1,000 USD 3 months from now. This increases security for both of their businesses. Because a futures contract is a binding contract between two parties, neither party can drop out of the contract: Even if the price for pork bellies is 1,200 USD at the time of execution, trader A is still contractually obliged to sell for 1,000 USD.
