In addition, the Advisor, any of its affiliates or employees and the Funds have a policy not to enter into any agreement or other understanding—whether written or oral—under which brokerage transactions or remuneration are directed to a broker to pay for distribution of a Fund’s shares. The table below sets forth the brokerage commissions paid by each Fund for the period noted for each Fund. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on brokerage commissions paid by the Fund is not included in this SAI.
The introduction of futures didn't lead to a wave of hedge-fund money shorting bitcoin. It led to retail and institutional money going long bitcoin. We talked last week about the spread between Cboe's bitcoin futures price and the actual price of bitcoin, which was wider than $1,000 for a while. The spread has tightened considerably -- as of 8:15 a.m. today, the CME futures traded at $18,585, Cboe futures at $18,670, and spot bitcoin at about $18,245, for a spread of about 2 percent -- but it still exists. Why would you pay more for a synthetic bitcoin in a month than you would for an actual bitcoin today? The answer, presumably, is that the synthetic bitcoin is more valuable to you: You want bitcoin exposure, but you'd prefer to get it through a standardized contract on a regulated exchange that settles in dollars. 
JUNK BONDS. “Junk Bonds” generally offer a higher current yield than that available for higher-grade issues. However, lower-rated securities involve higher risks, in that they are especially subject to adverse changes in general economic conditions and in the industries in which the issuers are engaged, to changes in the financial condition of the issuers and to price fluctuations in response to changes in interest rates. During periods of economic downturn or rising interest rates, highly leveraged issuers may experience financial stress that could adversely affect their ability to make payments of interest and principal and increase the possibility of default. In addition, the market for lower-rated debt securities has expanded rapidly in recent years, and its growth paralleled a long economic expansion. At times in recent years, the prices of many lower-rated debt securities declined substantially, reflecting an expectation that many issuers of such securities might experience financial difficulties. As a result, the yields on lower-rated debt securities rose dramatically, but the higher yields did not reflect the value of the income stream that holders of such securities expected. Rather, the risk that holders of such securities could lose a substantial portion of their value as a result of the issuers’ financial restructuring or default. There can be no assurance that such declines will not recur. The market for lower-rated debt issues generally is thinner and less active than that for higher quality securities, which may limit each Fund’s ability to sell such securities at fair value in response to changes in the economy or financial markets. Adverse publicity and investor perceptions, whether or not based on fundamental analysis, may also decrease the values and liquidity of lower-rated securities, especially in a thinly traded market. Changes by recognized rating services in their rating of a fixed income security may affect the value of these investments. Each Fund will not necessarily dispose of a security when its rating is reduced below the rating it had at the time of purchase. However, the Advisor will monitor the investment to determine whether continued investment in the security will assist in meeting each Fund’s investment objective.
When the market for certain futures contracts is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the “rolling process” of the more nearby bitcoin futures contracts would take place at a price that is lower than the price of the more distant bitcoin futures contracts. This pattern of higher futures prices for longer expiration bitcoin futures contracts is often referred to as “contango.” Alternatively, when the market for certain bitcoin futures contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the “rolling process” of the more nearby bitcoin futures contracts would take place at a price that is higher than the price of the more distant bitcoin futures contracts. This pattern of higher future prices for shorter expiration bitcoin futures contracts is referred to as “backwardation.”

Cryptocurrencies are far more volatile than stocks and bonds, and the industry evolves rapidly. An altcoin that is popular today may not exist a month or a year from now. In other words, traders should consider the possibility of losing everything when they start trading. For this reason, you should put only a very small portion of your portfolio in this sector.
If a Fund that writes an option wishes to terminate the Fund’s obligation, the Fund may effect a “closing purchase transaction.” The Fund accomplishes this by buying an option of the same series as the option previously written by the Fund. The effect of the purchase is that the writer’s position will be canceled by the OCC. However, a writer may not effect a closing purchase transaction after the writer has been notified of the exercise of an option. Likewise, a Fund which is the holder of an option may liquidate its position by effecting a “closing sale transaction.” The Fund accomplishes this by selling an option of the same series as the option previously purchased by the Fund. There is no guarantee that either a closing purchase or a closing sale transaction can be effected. If any call or put option is not exercised or sold, the option will become worthless on its expiration date. A Fund will realize a gain (or a loss) on a closing purchase transaction with respect to a call or a put option previously written by the Fund if the premium, plus commission costs, paid by the Fund to purchase the call or put option to close the transaction is less (or greater) than the premium, less commission costs, received by the Fund on the sale of the call or the put option. The Fund also will realize a gain if a call or put option which the Fund has written lapses unexercised, because the Fund would retain the premium.
In addition, there may be times when the market price and the value of the Fund’s holdings vary significantly and you may pay more than the value of the Fund’s holdings when buying the Fund’s shares on the secondary market, and you may receive less than the value of the Fund’s holdings when you sell those shares. While the creation/ redemption feature is designed to make it likely that shares normally will trade close to the value of the Fund’s holdings, disruptions to creations and redemptions may result in trading prices that differ significantly from the value of the Fund’s holdings. The market price of shares, like the price of any exchange-traded security, includes a “bid-ask spread” charged by the exchange specialist, market makers or other participants that trade the particular security. In times of severe market disruption, the bid-ask spread often increases significantly. This means that shares may trade at a discount to the value of the Fund’s holdings, and the discount is likely to be greatest when the price of shares is falling fastest, which may be the time that you most want to sell your shares. 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 shares directly with the Fund.
As of September 16, 2017, the Trustees and officers of the Trust, as a group, owned outstanding shares that entitled them to give voting instructions with respect to less than one percent of the shares of any series of the Trust; except that Mr. Michael L. Sapir owned more than 25% of the outstanding shares of ProShares S&P 500 Ex-Financials ETF and ProShares S&P 500 Ex-Health Care ETF.
•   Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShare Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies.
With BitVC and OKCoin you can hold simultaneous long and short positions on the same contract. In BitMEX you can not. Technically it makes no sense to hold opposite simultaneous positions because it just cancels each other out. You may as well just close the position instead. There are some who still prefer, for psychological reasons, to use this and wrongly call it a "hedge", but really you're better off saving the trading fees and just getting out of a position if your outlook on a trade has changed.

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 validity of each cryptocurrency's coins is provided by a blockchain. A blockchain is a continuously growing list of records, called blocks, which are linked and secured using cryptography.[28][31] Each block typically contains a hash pointer as a link to a previous block,[31] a timestamp and transaction data.[32] By design, blockchains are inherently resistant to modification of the data. It is "an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way".[33] For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for validating new blocks. Once recorded, the data in any given block cannot be altered retroactively without the alteration of all subsequent blocks, which requires collusion of the network majority.
The first decentralized cryptocurrency, bitcoin, was created in 2009 by pseudonymous developer Satoshi Nakamoto. It used SHA-256, a cryptographic hash function, as its proof-of-work scheme.[16][17] In April 2011, Namecoin was created as an attempt at forming a decentralized DNS, which would make internet censorship very difficult. Soon after, in October 2011, Litecoin was released. It was the first successful cryptocurrency to use scrypt as its hash function instead of SHA-256. Another notable cryptocurrency, Peercoin was the first to use a proof-of-work/proof-of-stake hybrid.[18] IOTA was the first cryptocurrency not based on a blockchain, and instead uses the Tangle.[19][20] Many other cryptocurrencies have been created though few have been successful, as they have brought little in the way of technical innovation.[21] On 6 August 2014, the UK announced its Treasury had been commissioned to do a study of cryptocurrencies, and what role, if any, they can play in the UK economy. The study was also to report on whether regulation should be considered.[22]

An Authorized Participant that wishes to place an order to purchase Creation Units outside the Clearing Process must state that it is not using the Clearing Process and that the purchase instead will be effected through a transfer of securities and cash directly through DTC or as described below for Global Funds (defined below). Purchases (and redemptions) of Creation Units of the Matching and Ultra ProShares Funds settled outside the Clearing Process will be subject to a higher Transaction Fee than those settled through the Clearing Process. Purchase orders effected outside the Clearing Process are likely to require transmittal by the Authorized Participant earlier on the transmittal date than orders effected using the Clearing Process. Those persons placing orders outside the Clearing Process should ascertain the deadlines applicable to DTC and the Federal Reserve Bank wire system by contacting the operations department of the broker or depository institution effectuating such transfer of Deposit Securities and Balancing Amount (for the Matching and Ultra ProShares Funds), each as applicable and at the discretion of the Advisor, or of the Cash Purchase Amount together with the applicable Transaction Fee.
Whether a Fund realizes a gain or loss from futures activities depends generally upon movements in the underlying currency, commodity, security or index. The extent of a Fund’s loss from an unhedged short position in futures contracts or from writing options on futures contracts is potentially unlimited, and investors may lose the amount that they invest plus any profits recognized on their investment. The Funds may engage in related closing transactions with respect to options on futures contracts. The Funds will engage in transactions in futures contracts and related options that are traded on a U.S. exchange or board of trade or that have been approved for sale in the U.S. by the Commodity Futures Trading Commission (“CFTC”).
If this sounds confusing to you, then don't worry. In practice, these futures contracts are just like buying and selling spot market value. Just focus on the price of the contract and whether you are LONG or SHORT. If you're long and the futures price goes up, the BTC value of the contract goes up and you have bought an asset that is increasing in value.
In addition, the Advisor, any of its affiliates or employees and the Funds have a policy not to enter into any agreement or other understanding—whether written or oral—under which brokerage transactions or remuneration are directed to a broker to pay for distribution of a Fund’s shares. The table below sets forth the brokerage commissions paid by each Fund for the period noted for each Fund. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on brokerage commissions paid by the Fund is not included in this SAI.

The identity and number of shares of the Deposit Securities required for a Portfolio Deposit for each Fund changes as rebalancing adjustments and corporate action events are reflected from time to time by ProShare Advisors with a view to the investment objective of the applicable Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the securities constituting the relevant securities index, as applicable. The adjustments described above will reflect changes, known to ProShare Advisors on the date of announcement to be in effect by the time of delivery of the Portfolio Deposit, in the composition of the subject index being tracked by the relevant Fund, as applicable, or resulting from stock splits and other corporate actions. In addition, the Trust reserves the right to permit or require the substitution of an amount of cash (i.e., a “cash in lieu” amount) to be added to the Balancing Amount to replace any Deposit Security which may not be available in sufficient quantity for delivery or for other similar reasons. A Transaction Fee may be assessed on any “cash in lieu” amounts, as further described below under “Transaction Fees”. For the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a minimum of 70% of the Deposit Securities must be delivered, unless such purchase is made on a cash-only basis.

In February 2014 the world's largest bitcoin exchange, Mt. Gox, declared bankruptcy. The company stated that it had lost nearly $473 million of their customers' bitcoins likely due to theft. This was equivalent to approximately 750,000 bitcoins, or about 7% of all the bitcoins in existence. The price of a bitcoin fell from a high of about $1,160 in December to under $400 in February.[85]
As a result of compounding, for periods greater than one day, the use of leverage tends to cause the performance of a Fund to vary from its benchmark performance times the stated multiple or inverse multiple in the Fund’s investment objective, before accounting for fees and fund expenses. Compounding affects all investments, but has a more significant impact on geared funds. Four factors significantly affect how close daily compounded returns are to longer-term benchmark returns times the fund’s multiple: the length of the holding period, benchmark volatility, whether the multiple is positive or inverse, and its leverage level. Longer holding periods, higher benchmark volatility, inverse exposure and greater leverage each can lead to returns farther from the multiple times the benchmark return. As the tables below show, particularly during periods of higher benchmark volatility, compounding will cause longer term results to vary from the benchmark performance times the stated multiple in the Fund’s investment objective. This effect becomes more pronounced as volatility increases.

Expenses of preparation and presentation of a defense to any claim, action, suit or proceeding subject to a claim for indemnification under Section 8.5 of the Declaration of Trust shall be advanced by the Trust prior to final disposition thereof upon receipt of an undertaking by or on behalf of the recipient to repay such amount if it is ultimately determined that he or she is not entitled to indemnification under Section 8.5 of the Declaration of Trust, provided that either: Covered Person, unless there has been either a determination that such Covered Person did not engage in willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of this office by the court or other body approving the settlement or other disposition, or a reasonable determination, based on a review of readily available facts (as opposed to a full trial-type inquiry), that he or she did not engage in
There are so many hoops to jump through to set up for mining and each coin has its quirks. The power of your machine and graphix card and your power consumption are all important. My friend mined for 8month Eth and only made couple of hundred bucks by time you subtract power useage etc. He already had a powerful machine used in film industry for video graphix just sitting around so he thought he’d put it to use over that time for a laugh and see what happened. It took many hours messing around to set up and occassionally nursing it over that period. Of course he had to use his machine also occassionally which compromised the performance.
Set forth below is a general discussion of certain U.S. federal income tax issues concerning the Funds and the purchase, ownership, and disposition of a Fund’s Shares. This discussion does not purport to be complete or to deal with all aspects of federal income taxation that may be relevant to shareholders in light of their particular circumstances, nor to certain types of shareholders subject to special treatment under the federal income tax laws (for example, life insurance companies, banks and other financial institutions, and IRAs and other retirement plans). This discussion is based upon present provisions of the Code, the regulations promulgated thereunder, and judicial and administrative ruling authorities, all of which are subject to change, which change may be retroactive. Prospective investors should consult their own tax advisors with regard to the federal tax consequences of the purchase, ownership, or disposition of a Fund’s Shares, as well as the tax consequences arising under the laws of any state, foreign country, or other taxing jurisdiction.

In pure financial theory, the value of a futures contract is based on a "no arbitrage condition" from the interest rates in each asset. We have Bitcoin and US Dollar. Bitcoin interest rates tend to be less than US Dollar interest rates, so when you want to replicate the future value of bitcoin in US dollars, you have to borrow USD at, say, 5%, and invest in Bitcoin at 1% return. This requires a premium on the futures exchange to be able to hedge that trade. 
In contrast, if you are “going short” on Bitcoin, you assume that Bitcoin prices will fall. Buying put options will enable you to sell Bitcoin at some point in the future at a price that is higher than the future price you expect. In analogy to the example above, if the current Bitcoin price is 5,000 USD and you expect it to fall to 2,000 USD in 6 months, then put options allowing you to sell Bitcoin for 5,000 USD in 5 months (when everyone else is selling for 2000 USD) are very valuable.
