Certain Funds expect to invest in exchange-traded funds, including exchange-traded funds registered under the 1940 Act (“Underlying ETFs”). Some such Underlying ETFs will be treated as regulated investment companies for federal income tax purposes (each such Underlying ETF, an “Underlying RIC”). In such cases, a Fund’s income and gains will normally consist, in whole or part, of dividends and other distributions from the Underlying RICs and gains and losses on the disposition of shares of the Underlying RICs. The amount of income and capital gains realized by a Fund and in turn a Fund’s shareholders in respect of the Fund’s investments in Underlying RICs may be greater than such amounts would have been had the Fund invested directly in the investments held by the Underlying RICs, rather than in the shares of the Underlying RICs. Similarly, the character of such income and gains (e.g., long-term capital gain, eligibility for the dividends-received deduction, etc.) will not necessarily be the same as it would have been had the Fund invested directly in the investments held by the Underlying RICs.
Under an investment advisory agreement between ProShare Advisors and the Trust, on behalf of each Fund (the “Agreement” or “Advisory Agreement”), each Fund (other than the Morningstar Alternatives Solution ETF, the Global Listed Private Equity ETF, the Short Term USD Emerging Markets Bond ETF, the Inflation Expectations ETF and the CDS Short North American HY Credit ETF) pays ProShare Advisors a fee at an annualized rate, based on its average daily net assets, of 0.75%. ProShare Advisors has entered into an Advisory Fee Waiver Agreement for each of these Funds that reduces the annualized rate based on its average daily net assets, as follows: 0.75% of the first $4.0 billion of average daily net assets of the Fund; 0.70% of the average daily net assets of the Fund over $4.0 billion to $5.5 billion; 0.65% of the average daily net assets of the Fund over $5.5 billion to $7.0 billion; 0.60% of the average daily net assets of the Fund over $7.0 billion to $8.5 billion; and 0.55% of the average daily net assets of the Fund over $8.5 billion. The fee waiver arrangement will remain in effect through at least September 30, 2018 and prior to such date ProShare Advisors may not terminate the arrangement without the approval of the Board.

The Declaration of Trust of the Trust disclaims liability of the shareholders or the Officers of the Trust for acts or obligations of the Trust which are binding only on the assets and property of the Trust. The Declaration of Trust provides for indemnification of the Trust’s property for all loss and expense of any Funds shareholder held personally liable for the obligations of the Trust. The risk of a Trust shareholder incurring financial loss on account of shareholder liability is limited to circumstances where the Funds would not be able to meet the Trust’s obligations and this risk, thus, should be considered remote.
Capital losses in excess of capital gains (“net capital losses”) are not permitted to be deducted against a Fund’s net investment income. Instead, potentially subject to certain limitations, a Fund may carry net capital losses forward from any taxable year to subsequent taxable years to offset capital gains, if any, realized during such subsequent taxable years. Distributions from capital gains are generally made after applying any available capital loss carryforwards. Capital loss carryforwards are reduced to the extent they offset current-year net realized capital gains, whether the Funds retain or distribute such gains. If a Fund incurs or has incurred net capital losses in taxable years beginning after December 22, 2010 (post-2010 losses), those losses will be carried forward to one or more subsequent taxable years, and will be treated as realized on the first day of the taxable year in which it is used to reduce capital gain, without expiration; any such carryforward losses will generally retain their character as short-term or long-term and will be applied first against gains of the same character before offsetting gains of a different character (e.g., net capital losses resulting from previously realized net long-term losses will first offset any long-term capital gain, with any remaining amounts available to offset any net short-term capital gain). If a Fund incurred net capital losses in a taxable year beginning on or before December 22, 2010 (“pre-2011 losses”), the Fund is permitted to carry such losses forward for eight taxable years; in the year to which they are carried forward, such losses are treated as short-term capital losses that first offset any short-term capital gains, and then offset any long-term capital gains. A Fund must use any post-2010 losses, which will not expire, before it uses any pre-2011 losses. This increases the likelihood that pre-2011 losses will expire unused at the conclusion of the eight-year carryforward period.
It bears repeating -- when trading futures on leverage, you are not "borrowing" the money, so you don't have to pay a financing rate on your positions. Even though you are 100x exposed, you don't have to pay 100x financing (unless you're trading the perpetual swap, which is not a futures contract, but has similar characteristics). Since bitcoin futures do tend to trade at a premium, you are in a way paying an implied interest rate in the contract, because if you want to go long, you have to pay above spot, so you pay the interest up front in the contract, in a way.
The Funds may invest in bitcoin-based futures contracts, swap agreements, and options contracts, which are types of derivative contracts. A derivative refers to any financial instrument whose value is derived, at least in part, from the price of an underlying security, commodity, asset, rate, or index. The use of derivatives presents risks different from, and possibly greater than, the risks associated with investing directly in traditional securities. Changes in the value of a derivative may not correlate perfectly with the underlying security, asset, rate or index. Gains or losses in a derivative may be magnified and may be much greater than the derivative’s original cost. Because bitcoin-based derivatives were only recently introduced, the degree to which bitcoin-based derivatives are likely to provide exposure to movements in the price of bitcoin is extremely uncertain. If market participants executing trades in bitcoin-based derivatives face constraints, including capital constraints, security risks, or high execution costs with respect to direct investments in bitcoin, the price at which bitcoin-based derivatives trade may fail to capture price movements in the underlying price of bitcoin. Moreover, it is not clear how changes to the Bitcoin Network and determinations by any relevant derivatives exchange with respect to such changes to the Bitcoin Network will affect the value of any positions in bitcoin-based derivatives. [[In December 2015, the SEC proposed a new rule to regulate the use of derivatives by registered investment companies, such as the Fund. Whether and when this proposed rule will be adopted and its potential effects on the Fund are unclear as of the date of this Prospectus.]]
Individual shares of the Fund will be listed for trading on [the Exchange] and can be bought and sold in the secondary market at market prices. The market price of shares will fluctuate in response to changes in the value of the Fund’s holdings, supply and demand for shares, and other market factors. ProShare Advisors cannot predict whether the Fund’s shares will trade above, below or at a price equal to the value of the Fund’s holdings. Differences between secondary market prices and NAV, the value of the Fund’s holdings, may be due largely to supply and demand forces in the secondary market, which may not be the same forces as those influencing prices for securities or financial instruments held by the Fund at a particular time. Given the fact that the Fund’s shares can be created and redeemed in Creation Units, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained.
  •   Intellectual property rights claims may adversely affect the operation of the Bitcoin Network. Third parties may assert intellectual property rights claims relating to the operation of the Bitcoin Network. Regardless of the merit of any intellectual property or other legal action, any threatened action that reduces confidence in the Bitcoin Network’s long-term viability or the ability of end-users to hold and transfer bitcoin may adversely affect the price of bitcoin and adversely affect the price of the bitcoin futures contracts held by the Fund.
Since you bought 68.4246 BTC, you want to short 68 BTC and lock in the USD value. You will have 0.4246 BTC left over, which will give you a slightly long bias. You can either fix this by only buying 68 BTC in step 1 or by giving yourself more short exposure by shorting 69 BTC. Remember that CryptoFacilities contracts are inverse (which allow locking in USD) and are denominated in BTC
