The Fund invests in financial instruments that ProShare Advisors believes, in combination, should produce daily returns consistent with the Daily Target. In this manner, the Fund seeks daily returns that correspond to two times the inverse (-2x) of the price of bitcoin. The Fund does not directly short 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.
