the option to purchase the asset underlying the option at the exercise price if the option is exercised. During the term of the option, the writer may be assigned an exercise notice by the broker-dealer through whom the option was sold. The exercise notice would require the writer to deliver, in the case of a call, or take delivery of, in the case of a put, the underlying asset against payment of the exercise price. This obligation terminates upon expiration of the option, or at such earlier time that the writer effects a closing purchase transaction by purchasing an option covering the same underlying asset and having the same exercise price and expiration date as the one previously sold. Once an option has been exercised, the writer may not execute a closing purchase transaction. To secure the obligation to deliver the underlying asset in the case of a call option, the writer of a call option is required to deposit in escrow the underlying asset or other assets in accordance with the rules of the Options Clearing Corporation (the “OCC”), an institution created to interpose itself between buyers and sellers of options. The OCC assumes the other side of every purchase and sale transaction on an exchange and, by doing so, gives its guarantee to the transaction. When writing call options on an asset, a Fund may cover its position by owning the underlying asset on which the option is written. Alternatively, the Fund may cover its position by owning a call option on the underlying asset, on a share-for-share basis, which is deliverable under the option contract at a price no higher than the exercise price of the call option written by the Fund or, if higher, by owning such call option and depositing and segregating cash or liquid instruments equal in value to the difference between the two exercise prices. In addition, a Fund may cover its position by segregating cash or liquid instruments equal in value to the exercise price of the call option written by the Fund. When a Fund writes a put option, the Fund will segregate with its custodian bank cash or liquid instruments having a value equal to the exercise value of the option. The principal reason for a Fund to write call options on assets held by the Fund is to attempt to realize, through the receipt of premiums, a greater return than would be realized on the underlying assets alone.
The NAV of each Fund is typically determined each business day at 3:00 p.m., Eastern Time on days when                    is open for trading. The [            ] Exchange is open every week, Monday through Friday, except when the following holidays are celebrated: New Year’s Day, Martin Luther King, Jr. Day (the third Monday in January), Presidents’ Day (the third Monday in February), Good Friday, Memorial Day (the last Monday in May), Independence Day, Labor Day (the first Monday in September), Thanksgiving Day (the fourth Thursday in November) and Christmas Day. An Exchange may close early on the business day before each of these holidays and on the day after Thanksgiving Day. Exchange holiday schedules are subject to change without notice. If the exchange or market on which a Fund’s investments are primarily traded closes early, the NAV may be calculated prior to its normal calculation time. Creation/ redemption transaction order time cutoffs would also be accelerated.

When a market price is not readily available, each Fund’s investments are valued at fair value in good faith under procedures established by, and under the general supervision and responsibility of, the Board. The use of a fair valuation method may be appropriate if, for example: (i) market quotations do not accurately reflect fair value of an investment; (ii) an investment’s value has been materially affected by events occurring after the close of the exchange or market on which the investment is principally traded; (iii) a trading halt closes an exchange or market early; or (iv) other events result in an exchange or market delaying its normal close. This procedure incurs the unavoidable risk that the valuation may be higher or lower than the securities might actually command if the Funds sold them. See the SAI for more details.
Portfolio managers are generally responsible for multiple investment company accounts. As described below, certain inherent conflicts of interest arise from the fact that a portfolio manager has responsibility for multiple accounts, including conflicts relating to the allocation of investment opportunities. Listed below for each portfolio manager are the number and type of accounts managed or overseen by such portfolio manager as of May 31, 2017.

•   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.
•   Tax Risk — In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, the Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. The Fund’s pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
This mega-powerful currency has not only opened the gate for other currencies, but also leads the cryptocurrency world with pride. It is governed to make sure no extra Bitcoin is produced, as a maximum quantity of 21 Million Bitcoin units was agreed to. When introduced, the rate was $1 to 1,309 BTC. The wheel has turned, and when Bitcoin reached the all-time high of $19,783.21 in 2017, it was certainly a meaningful milestone for Satoshi Nakamoto, the creator of Bitcoin.
The existence of market makers (e.g., Virtu Financial) refutes a common assertion about futures—that there‘s always a loser for every winner, that it’s a zero-sum game. It’s true that derivatives like stock options and futures are created in matched pairs—a long and a short contract. If two speculators own those two contracts the profits on one side are offset by losses on the other but market makers are not speculators. In general, they’re not betting on the direction of the market. They act as intermediaries, selling to buyers at the higher ask price and buying from sellers at the lower bid price— collecting the difference.

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.
