In order to make sure that you actually have money in your margin account to settle the difference with Mortimer every day, you are required to put up an initial margin at the beginning of the contract. A lower sum, the so-called minimum margin or maintenance margin, is also defined by the broker. If the money in your margin account falls from the initial margin to the maintenance margin, it triggers a margin call: The broker requests you to fill up your margin account to at least the initial margin (of course, you may also put up more).
New altcoins often make unsubstantiated claims about their products. Recently the US Securities and Exchange Commission (SEC) filed fraud charges against two ICOs it says were sold on the basis of fraudulent claims. China has banned the sale of ICOs, and many individuals familiar with fraud, including the famed Wolf of Wall Street, Jordan Belfort, have described ICOs as the biggest scam ever.
It is expected that each Subsidiary will neither be subject to taxation on its net income in the same manner as a corporation formed in the United States nor subject to branch profits tax on the income and gain derived from its activities in the United States. A foreign corporation will generally not be subject to such taxation unless it is engaged in or is treated as engaged in a U.S. trade or business. Each Subsidiary expects to operate in a manner such that it is not so engaged or so treated.
Each Fund generally engages in closing or offsetting transactions before final settlement of a futures contract wherein a second identical futures contract is sold to offset a long position (or bought to offset a short position). In such cases, the obligation is to deliver (or take delivery of) cash equal to a specific dollar amount (the contract multiplier) multiplied by the difference between the price of the offsetting transaction and the price at which the original contract was entered into. If the original position entered into is a long position (futures contract purchased), there will be a gain (loss) if the offsetting sell transaction is carried out at a higher (lower) price, inclusive of commissions. If the original position entered into is a short position (futures contract sold) there will be a gain (loss) if the offsetting buy transaction is carried out at a lower (higher) price, inclusive of commissions.
Ultimately, the big and yet unanswered question will continue to loom: is bitcoin indeed the millennials’ gold, as strategist Tom Lee suggests, and therefore has real and measurable value, or is it simply used for speculation as investors like Jack Bogle and Warren Buffet have implied? The answer that important investors will come up with for that question should have a significant impact on the price movement of bitcoin, and it is completely uncertain what it will look like.
The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in a combination of short positions in bitcoin futures contracts and money market instruments. The Fund is designed to benefit when the price of bitcoin futures contracts declines. The Fund generally seeks to have 30% of the value of its portfolio invested in short positions in bitcoin futures contracts and 70% of the value of its portfolio invested in money market instruments.
All Shares of the Trust are freely transferable. The Shares do not have preemptive rights or cumulative voting rights, and none of the Shares have any preference to conversion, exchange, dividends, retirements, liquidation, redemption or any other feature. Shares have equal voting rights, except that, in a matter affecting a particular series or class of Shares, only Shares of that series or class may be entitled to vote on the matter. Trust shareholders are entitled to require the Trust to redeem Creation Units of their Shares. The Declaration of Trust confers upon the Board of Trustees the power, by resolution, to alter the number of Shares constituting a Creation Unit or to specify that Shares may be individually redeemable. The Trust reserves the right to adjust the stock prices of Shares to maintain convenient trading ranges for investors. Any such adjustments would be accomplished through stock splits or reverse stock splits which would have no effect on the net assets of the applicable Fund.
The Funds are not required to enter into forward currency contracts for hedging purposes. It is possible, under certain circumstances, that the Fund may have to limit its currency transactions to qualify as a “regulated investment company” (“RIC”) under the Internal Revenue Code. The Funds do not intend to enter into a forward currency contract with a term of more than one year, or to engage in position hedging with respect to the currency of a particular country to more than the aggregate market value (at the time the hedging transaction is entered into) of their portfolio securities denominated in (or quoted in or currently convertible into or directly related through the use of forward currency contracts in conjunction with money market instruments to) that particular currency.
•   Market Price Variance Risk — Fund shares are 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 shares will trade above, below or at a price equal to the value of the Fund’s holdings. Given the fact that shares can be created and redeemed in Creation Units, as defined below, ProShare Advisors believes that large discounts or premiums to the value of the Fund’s holdings should not be sustained. The Fund’s investment results are measured based upon the daily NAV of the Fund. Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund. To the extent that exchange specialists, market makers, Authorized Participants, or other participants are unavailable or unable to trade the Fund’s shares and/or create or redeem Creation Units, trading spreads and the resulting premium or discount on the Fund’s shares may widen and the Fund’s shares may possibly be subject to trading halts and/or delisting.

The most common way to trade in Bitcoin and other cryptocurrency derivatives today is through contract-for-difference (CFD) contracts. These CFD contracts are usually traded over the counter (OTC), meaning that they are not traded on exchanges but directly between participants. Due to the high volatility (exceeding 1.5-2x std from the mean) most of the OTC platforms do not provide leverage on bitcoin and other cryptos CFDs.

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/Equity 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 value of such Creation Unit for the S&P 500 Dividend Aristocrats ETF, the MSCI EAFE Dividend Growers ETF, the DJ Brookfield Global Infrastructure ETF, the Global Listed Private Equity ETF, the Large Cap Core Plus, the Hedge Replication ETF, the Merger ETF, the Inflation Expectations ETF, the CDS Short North American HY Credit ETF, the UltraPro Short Financial Select Sector ETF, the UltraShort FTSE Europe ETF, the UltraPro Financial Select Sector ETF, and the Ultra High Yield ETF as of each such Fund’s inception was $2,000,000.
The ProShares Bitcoin/Blockchain Strategy ETF contains portfolio investments that are primarily listed on foreign markets. To the extent the Fund’s portfolio investments trade in foreign markets on days when the Fund is not open for business or when the primary exchange for its shares is not open, the value of the Fund’s assets may vary on days when shareholders may not be able to purchase or sell Fund shares and Authorized Participants may not be able to create or redeem Creation Units. Also, certain portfolio investments may not be traded on days the Fund is open for business.
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.
Traders A and B in the previous example are hedgers. However, futures contracts, once they exist, can also be bought and sold in their own right. This is where futures get interesting for speculators. Say that Speculator X believes the price of a ton of pork belly will rise to 1,200 USD in 3 months’ time, so buying the futures contract at 1,000 USD is a good deal. He can then sell the contract to bacon producers who want to buy pork bellies at 1,000 USD. The option to buy at a specified price in the future is known as a call option. The price of call options rise when traders assume that the price of the underlying asset will rise.
