Institutional-tier offerings such as those detailed above are seen as much-needed catalysts to stimulate the flow of institutional money into the market, offering heavyweight financial players a less-risky way to buy into assets like bitcoin. For the same reason, custody services like those offered by Coinbase, BitGo and others are necessary for safely storing and managing these investments as well.

D – An obligation rated ‘D’ is in default or in breach of an imputed promise. For non-hybrid capital instruments, the ‘D’ rating category is used when payments on an obligation are not made on the date due, unless Standard & Poor’s believes that such payments will be made within five business days in the absence of a stated grace period or within the earlier of the stated grace period or 30 calendar days. The ‘D’ rating also will be used upon the filing of a bankruptcy petition or the taking of similar action and where default on an obligation is a virtual certainty, for example due to automatic stay provisions. An obligation’s rating is lowered to ‘D’ if it is subject to a distressed exchange offer.
An Authorized Participant that wishes to place an order to purchase Creation Units outside the Clearing Process must state that it is not using the Clearing Process and that the purchase instead will be effected through a transfer of securities and cash directly through DTC or as described below for Global Funds (defined below). Purchases (and redemptions) of Creation Units of the Matching and Ultra ProShares Funds settled outside the Clearing Process will be subject to a higher Transaction Fee than those settled through the Clearing Process. Purchase orders effected outside the Clearing Process are likely to require transmittal by the Authorized Participant earlier on the transmittal date than orders effected using the Clearing Process. Those persons placing orders outside the Clearing Process should ascertain the deadlines applicable to DTC and the Federal Reserve Bank wire system by contacting the operations department of the broker or depository institution effectuating such transfer of Deposit Securities and Balancing Amount (for the Matching and Ultra ProShares Funds), each as applicable and at the discretion of the Advisor, or of the Cash Purchase Amount together with the applicable Transaction Fee.

Municipal notes with maturities of three years or less are usually given note ratings (designated SP-1 or SP-2) to distinguish more clearly the credit quality of notes as compared to bonds. Notes rated SP-1 have a very strong or strong capacity to pay principal and interest. Those issues determined to possess overwhelming safety characteristics are given the designation of SP-1+. Notes rated SP-2 have a satisfactory capacity to pay principal and interest.
  •   Intellectual property claims. A proliferation of recent startups attempting to apply blockchain technology in different contexts means the possibility of conflicting intellectual property claims could be a risk to an issuer, its operations or its business. This could also pose a risk to blockchain platforms that permit transactions in digital securities.

Fixed margin will isolate your margin to the individual position you have made in an instrument. So if you have 1 bitcoin in your account and you put 0.2btc margin for a Weeklies Futures long position, and it gets margin-called, you still have the 0.8btc left. However, if you're on cross-margin, also known as portfolio value margin, then your whole balance on the site is going to be used to back all your positions, and if you get margincalled, it's because you have run out of money on your whole account.

The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in a combination of short positions in bitcoin futures contracts and money market instruments. The Fund is designed to benefit when the price of bitcoin futures contracts declines. The Fund generally seeks to have 30% of the value of its portfolio invested in short positions in bitcoin futures contracts and 70% of the value of its portfolio invested in money market instruments.
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).
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. 
The identity and number of shares of the Deposit Securities required for a Portfolio Deposit for each Fund changes as rebalancing adjustments and corporate action events are reflected from time to time by ProShare Advisors with a view to the investment objective of the applicable Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the securities constituting the relevant securities index, as applicable. The adjustments described above will reflect changes, known to ProShare Advisors on the date of announcement to be in effect by the time of delivery of the Portfolio Deposit, in the composition of the subject index being tracked by the relevant Fund, as applicable, or resulting from stock splits and other corporate actions. In addition, the Trust reserves the right to permit or require the substitution of an amount of cash (i.e., a “cash in lieu” amount) to be added to the Balancing Amount to replace any Deposit Security which may not be available in sufficient quantity for delivery or for other similar reasons. A Transaction Fee may be assessed on any “cash in lieu” amounts, as further described below under “Transaction Fees”. For the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a minimum of 70% of the Deposit Securities must be delivered, unless such purchase is made on a cash-only basis.
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.
Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[110] and links it to Tulip mania.[111] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[112] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[113] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
!! WARNING !!! Note that on CryptoFacilities each contract is denominated by 1 BTC. So if you bought a fraction of BTC you can NOT perform a perfect hedge of the value. If you round the BTC you bought with start capital down, you will have slight overexposure LONG with the left-over BTC. If you round up and short an extra contract, you will have slight overexposure SHORT.
