When rolling futures contracts that are in contango, the Short Bitcoin Fund may buy the expiring bitcoin futures contract at a lower price and sell a longer-dated bitcoin futures contract at a higher price, resulting in a positive roll yield (i.e., a gain). When rolling futures contracts that are in backwardation, the Short Bitcoin Fund may buy the expiring bitcoin futures contract at a higher price and sell the longer-dated bitcoin futures contract at a lower price, resulting in a negative roll yield (i.e., a loss).
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 Bitcoin/Blockchain 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 Investment Company Act of 1940, as amended (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.

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.
The Trust has entered into an agreement with Foreside Management Services, LLC (“Foreside”), pursuant to which Foreside provides the Trust with the services of an individual to serve as the Trust’s Principal Financial Officer and Treasurer.

When a Fund purchases a put or call option on a futures contract, the Fund pays a premium for the right to sell or purchase the underlying futures contract for a specified price upon exercise at any time during the option period. By writing (selling) a put or call option on a futures contract, a Fund receives a premium in return for granting to the purchaser of the option the right to sell to or buy from the Fund the underlying futures contract for a specified price upon exercise at any time during the option period.
•   Investments by a Fund in options, futures, forward contracts, swap agreements and other derivative financial instruments are subject to numerous special and complex tax rules. These rules could affect the amount, timing or character of the distributions to shareholders by a Fund. In addition, because the application of these rules may be uncertain under current law, an adverse determination or future Internal Revenue Service guidance with respect to these rules may affect whether a Fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid fund-level tax.
Shares may be redeemed only in Creation Units at their NAV next determined after receipt of a redemption request in proper form by the Distributor on any Business Day. The Trust will not redeem Shares in amounts less than Creation Units. Beneficial owners also may sell Shares in the secondary market, but must accumulate enough Shares to constitute a Creation Unit in order to have such Shares redeemed by the Trust. There can be no assurance, however, that there will be sufficient liquidity in the public trading market at any time to permit assembly of a Creation Unit of Shares. Investors should expect to incur brokerage and other costs in connection with assembling a sufficient number of Shares to constitute a redeemable Creation Unit.
In traditional financial markets, derivatives are used as speculation objects as well as insurance against losses. The latter is known as hedging. One popular variety of derivatives used for hedging are called futures. A future is a contract between two parties in which one party agrees to pay the other a predetermined amount of money for an underlying asset at a specific point in time.
