In this manner, the Fund seeks daily returns that correspond to two times (2x) the price of bitcoin. The Fund does not invest directly in bitcoin. Bitcoin is a digital asset. The ownership and operation of bitcoin is determined by participants in an online, peer-to-peer network sometimes referred to as the Bitcoin Network. The Bitcoin Network connects computers that run publicly accessible, or open source, software that follows the rules and procedures governing the Bitcoin Network. This is commonly referred to as the Bitcoin Protocol (and is described in more detail in the section entitled The Bitcoin Protocol in the Funds Prospectus). Bitcoin may be used to pay for goods and services, stored for future use, or converted to a government-issued currency. As of the date of this Prospectus, the adoption of bitcoin for these purposes has been limited and bitcoin presently is not widely accepted as a means of payment. The value of bitcoin is not backed by any government, corporation, or other identified body. Instead, its value is determined in part by the supply and demand in markets created to facilitate trading of bitcoin. Ownership and transaction records for bitcoin are protected through public-key cryptography. The supply of bitcoin is determined by the Bitcoin Protocol. No single entity owns or operates the Bitcoin Network. The Bitcoin Network is collectively maintained by (1) a decentralized group of participants who run computer software that results in the recording and validation of transactions (commonly referred to as miners), (2) developers who propose improvements to the Bitcoin Protocol and the software that enforces the protocol and (3) users who choose which version of the bitcoin software to run. From time to time, the developers suggest changes to the bitcoin software. If a sufficient number of users and miners elect not to adopt the changes, a new digital asset, operating on the earlier version of the bitcoin software, may be created. This is often referred to as a fork. The value of the Fund may reflect the impact of these forks. The Index is designed to measure the performance of a single bitcoin traded in USD and seeks to provide a proxy for the bitcoin market. The Index price is a composite of U.S. dollar-bitcoin trading activities reported by certain digital asset trading platforms that are evaluated based on a variety of different criteria, including the trading platforms oversight and governance controls, liquidity, capital controls, data transparency and data integrity. The digital asset trading platforms included in the Index are reevaluated quarterly. The Index is constructed and maintained by Bloomberg Index Services Limited. More information about the Index can be found using the Bloomberg ticker symbol BITCOIN. Under normal circumstances, the Fund will invest at least 80% of the Funds assets in, or provide exposure to, financial instruments that ProShare Advisors believes, in combination, should produce daily returns consistent with the Daily Target. The Fund will invest principally in the financial instruments listed below. ? Derivatives Financial instruments whose value is derived from the value of an underlying asset or rate, such as bitcoin. These derivatives principally include: ? Bitcoin Futures Contracts In certain circumstances, for example, if the Fund is unable to obtain the desired exposure to bitcoin using swap agreements, the Fund may obtain exposure to bitcoin through standardized, cash-settled bitcoin futures contracts traded on commodity exchanges registered with the Commodity Futures Trading Commission (CFTC). The Fund seeks to invest in cash-settled, front-month bitcoin futures. Front-month bitcoin futures contracts are those contracts with the shortest time to maturity. ? Money Market Instruments The Fund expects that any cash balances maintained in connection with its use of derivatives will typically be held in high quality, short-term money market instruments, for example: ? U.S. Treasury Bills U.S. government securities that have initial maturities of one year or less, and are supported by the full faith and credit of the U.S. government. ? Repurchase Agreements Contracts in which a seller of securities, usually U.S. government securities or other money market instruments, agrees to buy the securities back at a specified time and price. ? Reverse Repurchase Agreements When the Fund invests in bitcoin futures contracts, the Fund may engage in reverse repurchase agreements, a form of borrowing or leverage, and use the proceeds to help achieve the Funds investment objective. ProShare Advisors uses a mathematical approach to investing in which it determines the type, quantity and mix of investment positions that it believes, in combination, the Fund should hold to produce daily returns consistent with the Daily Target. For these purposes a day is measured from the time of one net asset value (NAV) calculation to the next. The Fund seeks to remain fully invested at all times in financial instruments that, in combination, provide leveraged exposure consistent with the investment objective, without regard to market conditions, trends or direction. The Fund seeks to rebalance its portfolio each day so that its exposure to the Index is consistent with the Daily Target. The Indexs movements during the day will affect whether the Funds portfolio needs to be rebalanced. For example, if the Index has risen on a given day, net assets of the Fund should rise (assuming there were no Creation Unit redemptions). As a result, the Funds exposure will need to be increased. Conversely, if the Index has fallen on a given day, net assets of the Fund should fall (assuming there were no Creation Units issued). As a result, the Funds exposure will need to be decreased. In order to maintain its exposure to bitcoin futures contracts, the Fund must sell its futures contracts as they near expiration and replace them with new futures contracts with a later expiration date. This is often referred to as rolling a futures contract. Futures contracts with a longer term to expiration may be priced higher than futures contracts with a shorter term to expiration, a relationship called contango. When rolling futures contracts that are in contango, the Fund will sell the expiring contract at a relatively lower price and buy a longer-dated contract at a relatively higher price. Conversely, futures contracts with a longer term to expiration may be priced lower than futures contracts with a shorter term to expiration, a relationship called backwardation. When rolling futures contracts that are in backwardation, the Fund will sell the expiring contract at a relatively higher price and buy a longer-dated contract at a relatively lower price. The Fund expects to gain leveraged exposure by investing a portion of its assets in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands and advised by ProShare Advisors. Because the Fund intends to qualify for treatment as a regulated investment company (RIC) under Subchapter M of the Internal Revenue Code of 1986, as amended, the Fund intends to invest no more than 25% of the Funds total assets in the subsidiary at each quarter end of the Funds tax year. Exceeding this amount may have tax consequences, see the section entitled Tax Risk in the Funds Prospectus for more information. References to investments by the Fund should be read to mean investments by either the Fund or the subsidiary.
