the option to purchase the asset underlying the option at the exercise price if the option is exercised. During the term of the option, the writer may be assigned an exercise notice by the broker-dealer through whom the option was sold. The exercise notice would require the writer to deliver, in the case of a call, or take delivery of, in the case of a put, the underlying asset against payment of the exercise price. This obligation terminates upon expiration of the option, or at such earlier time that the writer effects a closing purchase transaction by purchasing an option covering the same underlying asset and having the same exercise price and expiration date as the one previously sold. Once an option has been exercised, the writer may not execute a closing purchase transaction. To secure the obligation to deliver the underlying asset in the case of a call option, the writer of a call option is required to deposit in escrow the underlying asset or other assets in accordance with the rules of the Options Clearing Corporation (the “OCC”), an institution created to interpose itself between buyers and sellers of options. The OCC assumes the other side of every purchase and sale transaction on an exchange and, by doing so, gives its guarantee to the transaction. When writing call options on an asset, a Fund may cover its position by owning the underlying asset on which the option is written. Alternatively, the Fund may cover its position by owning a call option on the underlying asset, on a share-for-share basis, which is deliverable under the option contract at a price no higher than the exercise price of the call option written by the Fund or, if higher, by owning such call option and depositing and segregating cash or liquid instruments equal in value to the difference between the two exercise prices. In addition, a Fund may cover its position by segregating cash or liquid instruments equal in value to the exercise price of the call option written by the Fund. When a Fund writes a put option, the Fund will segregate with its custodian bank cash or liquid instruments having a value equal to the exercise value of the option. The principal reason for a Fund to write call options on assets held by the Fund is to attempt to realize, through the receipt of premiums, a greater return than would be realized on the underlying assets alone.
The Fund will periodically adjust its holdings in order to maintain inverse exposure to bitcoin futures contracts. As the price of bitcoin futures contracts declines, net assets of the Fund will generally increase resulting in inverse exposure that is less than the value of the Fund’s assets. Conversely, when the price of bitcoin futures contracts increases, net assets of the Fund will generally decrease resulting in inverse exposure that is more than the value of the Fund’s assets, and the Fund’s inverse exposure will be periodically adjusted to restore approximately equivalent inverse exposure.

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. 
People are getting excited about Hempcoin (THC) because it’s slowly but surely starting to re-surface again and receive some of the media’s attention that it deserves. Even though a couple of competitors recently showed up (PotCoin and CannabisCoin) – Hempcoin is actually the oldest technologies and coins – not just in the industry – but in the crypto world altogether. Hempcoin was founded back in 2014 and its sole purpose is to act as a digital currency for the Agriculture/Farming industry and naturally – the Hemp/Marijuana field.
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.
•   Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the bitcoin futures contracts in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of ProShare Advisors. Markets may be disrupted by a number of events, including but not limited to cyber-attacks, economic crises, natural disasters, new legislation, or regulatory changes inside or outside the U.S.
(c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid—generally, taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year.
Credit Default Swaps (“CDS”): In the case of a CDS, the agreement will reference one or more debt securities or reference entities. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference entity has occurred. If a credit event occurs, the seller generally must pay the buyer: a) the full notional value of the swap; or b) the difference between the notional value of the defaulted reference entity and the recovery price/rate for the defaulted reference entity. CDS are designed to reflect changes in credit quality, including events of default. The CDS Short North American HY Credit ETF will normally be a “buyer” of CDS (also referred to as a buyer of protection or a seller of risk). The CDS Short North American HY Credit ETF will primarily invest in centrally cleared, index-based CDS that provide credit exposure through a single trade to a basket of reference entities. The CDS Short North American HY Credit ETF may also invest in single-name CDS. Single-name CDS provide exposure to a single reference entity and are not centrally cleared.

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.

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. Information on how the Funds voted proxies relating to portfolio securities for the 12-month (or shorter) period ended June 30 is available without charge, upon request, (1) by calling the Advisor at 888-776-3637, (2) on the Trust’s website at, and (3) on the SEC’s website at

Making money arbitraging bitcoin futures can be extremely simple. Futures contracts typically trade at a premium, and all you have to do, starting with USD, is buy bitcoin at Spot price and sell futures of the same amount at premium price. Then just wait until expiration to make your arb profit in bitcoin (which you can then put in USD). Whether it's a weekly, monthly, quarterly, or any futures contract, as long as it's in a premium, you lock in the sale price and earn the arbitrage profit.
