The Bitcoin Network and bitcoin, as an asset, currently hold a “first-to-market” advantage, often referred to as a “network effect,” over other digital assets. This first-to-market advantage has resulted in the Bitcoin Network evolving into the most well developed network of any digital asset. The Bitcoin Network enjoys the largest user base of any digital asset and, more importantly, the largest combined mining power in use to secure the Bitcoin Blockchain. Having a large mining network enhances user confidence regarding the security of the Bitcoin Blockchain and long-term stability of the Bitcoin Network. Despite the marked network effect advantage of the Bitcoin Network over other digital assets, it is possible that real or perceived shortcomings in the Bitcoin Network, technological, regulatory or other developments could result in a decline in popularity and acceptance of bitcoin and the Bitcoin Network.
CCC/CC/C – Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.
ProShare Advisors, pursuant to a separate Management Services Agreement, performs certain administrative services on behalf of the Funds, such as negotiating, coordinating and implementing the Trust’s contractual obligations with the Funds’ service providers; monitoring, overseeing and reviewing the performance of such service providers to ensure adherence to applicable contractual obligations; and preparing or coordinating reports and presentations to the Board of Trustees with respect to such service providers as requested or as deemed necessary. For these services, the Trust pays to ProShare Advisors a fee at the annual rate of 0.10% of average daily net assets for each of the Funds. ProShare Advisors has entered into an Advisory and Management Services Fee Waiver Agreement that waives this management services fee for the Morningstar Alternatives Solution ETF through at least October 31, 2018. Prior to this date, ProShare Advisors may not terminate the arrangement without the approval of the Board.
Created by Charlie Lee, a former Google engineer, Litecoin is an open-source payment network that operates on a global scale. It is not controlled by any centralized power, and it uses the “scrypt” as proof-of-work. It is similar to Bitcoin but has the advantage of offering a faster rate of generation and therefore faster transactions. This is one of the main reasons why its enthusiasts continue to invest or hold onto the coin even after finding out that its founder sold his stack.
  •   Government regulation could adversely impact the operation of the Bitcoin Network or the use of bitcoin. As bitcoin and other digital assets have grown in popularity and in market size, certain U.S. federal and state governments, foreign governments and self-regulatory agencies have begun to examine the operations of bitcoin, digital assets, the Bitcoin Network, bitcoin users and related issues. Although currently bitcoin is not regulated or is lightly regulated in most countries, including the United States, some countries have, and one or more countries may in the future, take regulatory actions that severely restrict the right to acquire, own, hold, sell or use bitcoin or to exchange bitcoin for fiat currency. Regulation in the U.S. and foreign jurisdictions may restrict the use of bitcoin or otherwise materially impact the global demand for bitcoin. Regulation of initial coin offerings (“ICOs”) and other cryptocurrencies may have an impact the price of bitcoin. If Bitcoin Exchanges become subject to regulation, that may also impact trading in bitcoin as trading may be concentrated in a smaller number of regulated exchanges, which may impact price, volatility and trading volumes. Also, most Bitcoin Exchanges currently require bitcoin trading accounts to be fully funded, but if margin trading is introduced, there may be additional risks, including increased volumes, higher volatility and higher risk that the exchanges would suffer counterparty defaults. Finally, the Bitcoin Exchanges may be required to comply with tax and other reporting obligations that make it more costly to transact in bitcoin (which may have an impact on price, volatility, or the trading of bitcoin more generally).
The Index Receipt Agent makes available through the NSCC on each Business Day, either immediately prior to the opening of business on the Exchange or the night before, the list of the names and the required number of shares of each Deposit Security to be included in the current Portfolio Deposit (based on information at the end of the previous Business Day) for each applicable Fund. Such Portfolio Deposit is applicable, subject to any adjustments as described below, in order to effect purchases of Creation Units of Shares of such Fund until the next-announced Portfolio Deposit composition is made available.

Banks may not provide banking services, or may cut off banking services, to businesses that provide bitcoin-related services or that accept bitcoin as payment, which could damage the public perception of bitcoin and the utility of bitcoin as a payment system and could decrease the price of bitcoin and the Bitcoin Instruments and adversely affect an investment in the Funds.
•   ETN Risk — The Fund is likely to obtain substantial exposure to the price movements of bitcoin by holding ETNs that provide exposure to the price of bitcoin. ETNs are unsecured, unsubordinated debt securities of an issuer that are listed and traded on a U.S. stock exchange. An ETN’s returns are generally linked to the performance of a particular market benchmark or strategy minus applicable fees. ETNs do not provide principal protection and may or may not make periodic coupon payments. ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due. Additionally, the value of an ETN may be influenced by time to maturity, level of supply and demand, volatility and lack of liquidity in the underlying market (e.g., the commodities market), changes in interest rates or the issuer’s credit rating, and other economic, legal, political or geographic events. The value of an investment in an ETN may be impacted by fees associated with the ETN. Structural aspects of the ETNs may impact their market value. Trading by affiliates of an ETN sponsor may create conflicts of interest. The issuer of an ETN may be unable to meet its obligations. The potential impact of Bitcoin Network forks on the value of a bitcoin ETN is unclear. ETNs issued by special purpose vehicles may include greater risk. ETNs are subject to risks associated with the underlying asset.
  negative impact on the price of such contracts. In order to comply with such limits, the Fund may be required to reduce the size of its outstanding positions or not enter into new positions that would otherwise be taken for the Fund. This could potentially subject the Funds to substantial losses or periods in which the Fund does not accept additional Creation Units.
Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. In many of these instances, the customers of such Bitcoin Exchanges were not compensated or made whole for the partial or complete losses of their account balances in such Bitcoin Exchanges. No Bitcoin Exchange is immune from these risks but the existence of these risks has created a higher barrier of entry for new Bitcoin Exchanges. The loss of confidence in new and smaller Bitcoin Exchanges and in the Bitcoin Exchange Market overall can slow down the mass adoption of bitcoin. Further, the failure of the Bitcoin Exchange Market or any other major component of the overall bitcoin ecosystem can have consequences for the Bitcoin Network, have an adverse effect on the price of bitcoin and could have a negative impact on the Bitcoin Instruments in which certain of the Funds invest.
  •   A decline in the adoption of bitcoin could have a negative effect on the price of bitcoin and bitcoin-related investments. Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. However, there can be no guarantees this growth will continue. Further, adoption of bitcoin as a means of payment has been limited when compared with the increase in the price of bitcoin, indicating that the majority of bitcoin’s use is for investment and speculative purposes. A lack of acceptance of bitcoin as a means of payment could negatively impact the price of the bitcoin futures contracts in which the Fund invests.

reporting systems. As of October 2016, the Advisor has separate arrangements to make payments, other than for the educational programs and marketing activities described above, to Charles Schwab & Co., Inc. and Raymond James Financial Services, Inc. (the “Firms”). Pursuant to the arrangements with the Firms, the Firms agreed to promote certain ProShares ETFs to each Firm’s customers and not to charge certain of their customers any commissions when those customers purchase or sell shares of certain ProShares ETFs. These payments, which may be significant, are paid by the Advisor from its own resources and not from the assets of the Funds. A discussion regarding the basis for the Board of Trustees approving the Advisory Agreement of the Trust will be (or is) available in the Trust’s Annual and/or Semi-Annual Report to shareholders. The Investment Advisory fees paid, as well as any amounts reimbursed pursuant to the Expense Limitation Agreement, for the fiscal years ended May 31, 2015, May 31, 2016 and May 31, 2017 for each Fund that was operational as of each date are set forth below. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on investment advisory fees paid by the Fund is not included in this SAI.

the Merrill Lynch Factor Model – Exchange Series benchmark). The Short ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Short”, “UltraShort” or “UltraPro Short” in their names, except for the Short Bitcoin Futures Strategy ETF) are designed to correspond to the inverse of the daily performance or an inverse multiple of the daily performance of an index. The Ultra ProShares Funds (i.e., the Geared ProShares Funds that have the prefix “Ultra” or UltraPro” in their names) are designed to correspond to a multiple of the daily performance of an index. The Funds, except the Matching ProShares Funds, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF, do not seek to achieve their stated investment objective over a period of time greater than a single day. A “single day” is measured from the time the Fund calculates its net asset value (“NAV”) to the time of the Fund’s next NAV calculation. Each Matching ProShares Fund, Managed Futures Strategy ETF, Crude Oil Strategy ETF, CDS Short North American HY Credit ETF, Bitcoin Futures Strategy ETF, Blockchain/Bitcoin Strategy ETF, Bitcoin Futures/Equity Strategy ETF, and Short Bitcoin Futures Strategy ETF seeks to achieve its stated investment objective both on a single day and over time. The Managed Futures Strategy ETF is actively managed and seeks to provide positive returns that are not directly correlated to broad equity or fixed income markets. The Crude Oil Strategy ETF is actively managed and seeks to provide exposure to the West Texas Intermediate crude oil futures markets. The CDS Short North American HY Credit ETF is actively managed and seeks to provide short exposure to the credit of debt issuers. The Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and bitcoin futures contracts. The Short Bitcoin Futures Strategy ETF is actively managed and seeks total return through investment in U.S. government securities and short exposure to bitcoin futures contracts. The Bitcoin Futures/Equity Strategy ETF is actively managed and seeks total return through investment in U.S. equity securities and bitcoin futures contracts. The Blockchain/Bitcoin Strategy ETF is actively managed and seeks total return through investment in the equity securities of blockchain technology companies and exposure to bitcoin investments.

Mortgage-backed securities issued by private issuers, whether or not such obligations are subject to guarantees by the private issuer, may entail greater risk than obligations directly or indirectly guaranteed by the U.S. government. The average life of a mortgage-backed security is likely to be substantially shorter than the original maturity of the mortgage pools underlying the securities. Prepayments of principal by mortgagors and mortgage foreclosures will usually result in the return of the greater part of principal invested far in advance of the maturity of the mortgages in the pool.
•   A Fund’s income from or the proceeds of dispositions of its non-U.S. investments may be subject to withholding and other taxes imposed by foreign countries, which will reduce the Fund’s return on and taxable distributions in respect of its non-U.S. investments. Tax conventions between certain countries and the United States may reduce or eliminate these taxes. If more than 50% of the value of a Fund’s total assets at the close of a taxable year consists of securities of foreign corporations, the Fund will be eligible to elect to “pass through” to you foreign income taxes that it has paid. If this election is made, you will be required to include your share of those taxes in gross income as a distribution from the Fund and you generally will be allowed to claim a credit (or a deduction, if you itemize deductions) for these amounts on your federal U.S. income tax return, subject to certain limitations.
The information in this Statement of Additional Information is not complete and may be changed. Shares of the Fund may not be sold until the registration statement filed with the Securities and Exchange Commission is effective. This Statement of Additional Information is not an offer to sell these securities and it is not soliciting an offer to buy these securities in any state where the offer or sale is not permitted.

Each Fund may invest in a wide range of fixed income securities, which may include foreign sovereign, sub-sovereign and supranational bonds, as well as any other obligations of any rating or maturity such as foreign and domestic investment grade corporate debt securities and lower-rated corporate debt securities (commonly known as “junk bonds”). Lower-rated or high yield debt securities include corporate high yield debt securities, zero-coupon securities, payment-in-kind securities, and STRIPS. Investment grade corporate bonds are those rated BBB or better by Standard & Poor’s Rating Group (“S&P”) or Baa or better by Moody’s Investor Services (“Moody’s”). Securities rated BBB by S&P are considered investment grade, but Moody’s considers securities rated Baa to have speculative characteristics. See Appendix A for a description of corporate bond ratings. The Funds may also invest in unrated securities.
While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[99] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[100] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[101] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[102] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[103] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.
•   Rolling Futures Contract Risk — The Fund will invest in and have exposure to bitcoin futures contracts and is subject to risks related to “rolling” such contracts. Rolling occurs when the Fund closes out of a futures contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold futures contracts through expiration, but instead intends to “roll” its futures positions. When the market for these 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 contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher futures contract prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for 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 contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher futures prices for shorter expiration futures contracts is referred to as “backwardation.” Extended periods of contango could cause significant losses for the Fund. The Advisor will utilize active management techniques to seek to mitigate the negative impact or, in certain cases, benefit from the contango or backwardation present in the various futures contract markets, but there can be no guarantee that it will be successful in doing so.

Well since then bitcoin is up more than 50 percent; it reached a record of $19,511 early Monday, hours after CME launched its futures contract. "Bitcoin Climbs as Futures Debut Fails to Incite Attack by Shorts," is the Bloomberg headline about Sunday's start of trading on CME. On the other hand, bitcoin was actually down a bit on the first full day of CME trading yesterday, and fell further overnight; "Bitcoin Futures Prices Fall in CME Debut" is the Wall Street Journal headline about Monday's trading. It is of course still very early days for the futures, and it's still possible that the shorts will come in and drive the price down. I guess it's even possible bitcoin bulls and bears will both flock to the futures market and trade with each other to find an efficient and stable price that reflects bitcoin's fundamental value, whatever that is.
Yields on U.S. government securities depend on a variety of factors, including the general conditions of the money and bond markets, the size of a particular offering, and the maturity of the obligation. Debt securities with longer maturities tend to produce higher yields and are generally subject to potentially greater capital appreciation and depreciation than obligations with shorter maturities and lower yields. The market value of U.S. government securities generally varies inversely with changes in market interest rates. An increase in interest rates, therefore, would generally reduce the market value of a Fund’s portfolio investments in U.S. government securities, while a decline in interest rates would generally increase the market value of a Fund’s portfolio investments in these securities.
Each Fund may provide redemptions in portfolio securities or cash at the Advisor’s discretion. With respect to the Matching and Ultra ProShares Funds, the Index Receipt Agent makes available through the NSCC immediately prior to the opening of business on the Exchange on each day that the Exchange is open for business the portfolio securities that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”). These securities, at times, may not be identical to Deposit Securities which are applicable to a purchase of Creation Units. The Fund may also, in its sole discretion, upon request of a shareholder, provide such redeeming shareholder a portfolio of securities which differs from the exact composition of the Fund Securities but does not differ in NAV.
Bob's transaction confirms first so he goes on BFE and looks at the contract selections. He wants to trade on the January 9 expiration contract. The orderbook is empty and Bob wants to go long (profit off an increase in bitcoin). Since there are no offers available, he places a limit order in the orderbook for a bid at 400 of 1 contract, using his 0.2btc as collateral for the position.

If you want to do scalping, then shorter-term expiree contracts that settle really soon would be fine. Keep in mind, the normal state of futures markets is "contango", which means that longer dated contracts will have a premium to the current spot rate, to reflect the interest rate differential and time preference.  This means you will see Weeklies maybe with a $1-2 preium and Quarterlies (assuming they expire months from now) with a $5-8 premium.  As an example we have Quarterlies contracts right now at OKCoin that settle on December 25. So we're just starting December now, that means that even though these are "Quarterlies" contracts by classification, they are expiring not 3 months from now, but 1 month from now. Don't mix up the settlement expiration date with the naming convention.

Futures contracts expire on a designated date, referred to as the “expiration date.” Each Fund typically will invest in “lead month” contracts. Lead month contracts are the monthly contracts with the earliest expiration date. Bitcoin futures contracts listed on the CBOE Futures Exchange (“CFE”) or Chicago Mercantile Exchange (“CME”) will be cash settled on their expiration date unless they are “rolled” prior to expiration. Each Fund generally intends to “roll” its bitcoin futures contracts prior to expiration to the next “nearby” bitcoin futures contract. The “nearby” contracts are those contracts with the next closest expiration date. The Funds will incur the costs (or benefits) of continually rolling into the new lead month contracts.

Yes but ... in cryptocurrencies? If you had borrowed 100 bitcoins to finance your working capital needs a year ago, you'd have financed about $79,000 worth of working capital. If you had to pay back 112 bitcoins today, that would come to a bit over $2 million, a dollar interest rate of over 2,400 percent. (If you'd borrowed ether you'd be paying over 12,000 percent.) Unless your working capital was bitcoin, you will not be able to pay back that loan. The lesson here is: Probably don't borrow an asset caught in a massive speculative frenzy to fund your working capital needs.

Speculating and hedging bitcoin with futures has never been easier. Spot has lower leverage which means you have to risk more of your capital with exchanges. Margin fees are very expensive on Bitfinex and Kraken when you are borrowing funds and paying up to 0.1% per day to be in a position. Futures contracts on the other hand have no holding fees associated. You pay a fee to enter the contract, and you pay a fee to exit the contract. Your profit or loss comes from the change in the price you pay.
A piece of software or hardware that gives you the ability to store and exchange your cryptocurrencies. Each cryptocurrency wallet is encrypted and unique. When you send funds you actually broadcast an encrypted message to the recipient. Only the recipient’s cryptocurrency wallet can decrypt that message and thus receive the funds. A hardware cryptocurrency wallet is considered to have key advantages over other software wallets:

Paul Krugman, Nobel Memorial Prize in Economic Sciences winner does not like bitcoin, has repeated numerous times that it is a bubble that will not last[110] and links it to Tulip mania.[111] American business magnate Warren Buffett thinks that cryptocurrency will come to a bad ending.[112] In October 2017, BlackRock CEO Laurence D. Fink called bitcoin an 'index of money laundering'.[113] "Bitcoin just shows you how much demand for money laundering there is in the world," he said.
There's a lot of ins and outs which can get confusing in arbitrage trading. We won't go into the technicals of why futures contracts trade at a premium to spot price. You can read a full explanation here. If it's not of interest to you, all you need to know is that there's a tendency, the further out in time the futures contract expires, for the premium to spot to be higher and higher in nominal percentage terms.
