The Fund seeks inverse or “short” exposure through short positions in bitcoin futures contracts and other financial instruments. This will cause the Fund to be exposed to certain risks associated with selling securities short. These risks include, under certain market conditions, an increase in the volatility and decrease in the liquidity of asset underlying the short position, which may lower the Fund’s return, result in a loss, have the effect of limiting the Fund’s ability to obtain inverse exposure through financial instruments such as swap agreements and futures contracts, or require the Fund to seek inverse exposure through alternative investment strategies that may be less desirable or more costly to implement. To the extent that, at any particular point in time, the asset underlying the short position may be thinly traded or have a limited market, including due to regulatory action, the Fund may be unable to meet its investment objective due to a lack of available securities or counterparties. During such periods, the Fund’s ability to issue additional Creation Units may be adversely affected. Obtaining inverse exposure through these instruments may be considered an aggressive investment technique. Any income, dividends or payments by the assets underlying the Fund’s short positions will negatively impact the Fund.
Collateralized mortgage obligations (“CMOs”) are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collateral collectively hereinafter referred to as “Mortgage Assets”). Multi-class pass-through securities are interests in a trust composed of Mortgage Assets and all references in this section to CMOs include multi-class pass-through securities. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semi-annual basis. The principal and interest payments on the Mortgage Assets may be allocated among the various classes of CMOs in several ways. Typically, payments of principal, including any prepayments, on the underlying mortgages are applied to the classes in the order of their respective stated maturities or final distribution dates, so that no payment of principal is made on CMOs of a class until all CMOs of other classes having earlier stated maturities or final distribution dates have been paid in full.
A futures curve shows the forward expectation of an asset’s price. Future rates of an asset can be calculated by extrapolating price from the risk-free theoretical spot rate of the asset. For example, one might calculate the possible future rate of an asset for the short (<1 month), medium (1-3 months) and long term (>3 months). In other words, future curves represent the demand for a specific asset and therefore the expected price evolution for the asset projected into the future. The curve is constructed from a discrete set of data points for various maturities. Initially, futures curves were used for hedging purposes, but with the evolution of the investment management industry, futures curves have become basic investment instruments not only for traditional commodities but also for new emerging asset classes.
Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]
If you are doing any active trading, set stop losses. For any coins not in your medium or long-term holds, always set stop losses. This is important for several reasons — the most obvious is mitigating your losses. But more importantly, you force yourself to decide on a point of acceptable loss, and because you now have a reference point, you are able to measure your effectiveness to keep or adjust for future trades. Sometimes, during a market dip, altcoins can plummet, and stop losses can lead to profitability by automatically selling for fiat that you can use to re-enter at lower prices.
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 Futures 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 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.

The CME Bitcoin futures contracts will be cash-settled, meaning that you will receive USD on the expiration date if your speculation was successful and you have not sold the derivative before the expiration date. You will not receive Bitcoin – that would be a physical settlement, even though Bitcoin is not a physical asset. This is a crucial difference because it enables traders to trade in Bitcoin futures without having a cryptocurrency wallet. Every transaction is done in USD.Thus, it is easy for mainstream traders to take part in this market.
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.
