Bitcoin is a relatively new type of currency—a digital or cryptocurrency secured through cryptography, or codes that can’t be read without a key. Traditional currencies are made up of paper bills and coins. Unlike traditional currencies, the bitcoin is not issued by any central government. Rather, a computer algorithm determines how many bitcoins are produced and added to the economy. This is much different than a traditional currency, where central banks typically determine how much money to print.
So be aware of the premium or discount that is on longer dated contracts, this can allow you some arbitrage opportunities if you are patient and have the coins to apply to it. In general, we recommend that you trade any contract that has good liquidity and high volume. This is the most important characteristic of ANY product for a trader. If you can't get in and out reliably, and have a price that reasonably follows the spot market behavior, then it's not worth trading.
The e-coin that is considered Ethereum’s biggest competitor. The EOS blockchain gained its fame because of the way it effectively records and secures transactions. It is similar to the Ethereum blockchain but faster, more scalable, and allows users to build decentralized applications more efficiently. Market analysts are promoting the currency as ‘The Most Powerful Infrastructure for Decentralized Applications’ and expect the coin to be dumped and pumped, which could provide some interesting short-term opportunities.

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.

•   Compounding Risk — In the course of managing the Fund’s investments, ProShare Advisors will need to periodically adjust the Fund’s holdings in order to maintain investment exposure approximately equivalent to the Fund’s assets. This process entails obtaining additional inverse exposure as the Fund experiences gains, and reducing inverse exposure as the Fund experiences losses. The higher the volatility of the bitcoin futures contracts in which the Fund invests, the more such rebalancing can adversely affect the Fund’s performance.
All three DBRS rating categories for short term debt use “(high)”, “(middle)” and “(low)” as subset grades to designate the relative standing of the credit within a particular rating category. The following comments provide separate definitions for the three grades in the Prime Credit Quality area, as this is where ratings for active borrowers in Canada continue to be heavily concentrated.
If, in any taxable year, a Fund were to fail to meet the 90% gross income, diversification or distribution test described above, the Fund could in some cases cure such failure, including by paying a Fund-level tax, paying interest, making additional distributions, or disposing of certain assets. If a Fund were ineligible to or did not cure such a failure for any taxable year, or otherwise failed to qualify as a RIC accorded special tax treatment under the Code, the Fund would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including distributions of net tax-exempt income and net long-term capital gain (if any), would be taxable to shareholders as dividend income. In such a case, distributions from the Fund would not be deductible by the Fund in computing its taxable income. In addition, in order to requalify for taxation as a RIC, the Fund may be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.
In order to provide current Share pricing information, an Exchange disseminates an updated Indicative Optimized Portfolio Value (“IOPV”) for each Fund. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no warranty as to the accuracy of the IOPVs. IOPVs are expected to be disseminated on a per Fund basis every 15 seconds during regular trading hours of an Exchange.
(a) derive in each taxable year at least 90% of its gross income from (i) dividends, interest, payments with respect to certain securities loans and gains from the sale or other disposition of stock, securities or foreign currencies, or other income (including but not limited to, gains from options, futures, or forward contracts) derived with respect to its business of investing in such stock, securities or currencies, and (ii) net income derived from interests in “qualified publicly traded partnerships” as described below (the income described in this subparagraph (a), “Qualifying Income”);
At or before the maturity of a forward currency contract, the Funds may either sell a portfolio security and make delivery of the currency, or retain the security and terminate its contractual obligation to deliver the currency by buying an “offsetting” contract obligating them to buy, on the same maturity date, the same amount of the currency. If the Fund engages in an offsetting transaction, it may later enter into a new forward currency contract to sell the currency.
An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the sum of the exchanger’s aggregate basis in the securities surrendered plus the amount of cash paid for such Creation Units. An Authorized Participant who redeems Creation Units will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of any securities received plus the amount of any cash received for such Creation Units. The IRS, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons purchasing or redeeming Creation Units should consult their own tax advisors with respect to the tax treatment of any creation or redemption transaction.
The Funds subject to the SEC “names rule” (Rule 35d-1 under the 1940 Act) have adopted non-fundamental investment policies obligating them to commit, under normal market conditions, at least 80% of their assets exposed to the types of securities suggested by their name and/or investments with similar economic characteristics. Such direct or inverse exposure may be obtained

  •   Bitcoin and investments linked to bitcoin, including bitcoin futures contracts, can be highly volatile and may experience large losses. The price of bitcoin has experienced periods of extreme volatility and low liquidity. Speculators and investors who seek to profit from trading and holding bitcoin currently account for a significant portion of bitcoin demand. Such speculation regarding the potential future appreciation in the value of bitcoin may artificially inflate the price of bitcoin. The price of bitcoin recently has been at or near all-time highs. There can be no guarantee this will continue and the market for bitcoin, and therefore bitcoin futures contracts, may change suddenly and without warning.
  •   Risks Associated with Bitcoin – The Fund is exposed to risks associated with bitcoin. Investing in or gaining exposure to Bitcoin may provide the Fund with increased risk. Various global factors may negatively impact the Fund’s performance including legal, regulatory, political, social, regional and economic events. These risks, which could have a negative impact on the performance of the Fund and the trading price of Fund shares, include the following:
While volatile movements take away the attractiveness of any asset, a certain amount of swing in price creates trading opportunities. This is something that many traders and speculators have been taking advantage of by buying the digital currency and then selling at a profit through an exchange. The whole process makes bitcoin exchanges an important part of the ecosystem since it facilitates the buying and selling of bitcoins, as well as futures trading.
You might buy in to your Ethereum position at $1000, you set your sell position $1300. Your sell order could take days, weeks, months, years or till the end of time to be filled. Once it has been filled, you then take that profit and you roll it over in to a new buy over at, say, $1100. Choosing good targets for your buy and sell orders is crucial if you want to be a successful swing trader but overall swing trading cryptocurrency is pretty easy – set your orders and then just wait.
The Funds may invest in a combination of forward currency contracts and U.S. dollar-denominated market instruments in an attempt to obtain an investment result that is substantially the same as a direct investment in a foreign currency-denominated instrument. This investment technique creates a “synthetic” position in the particular foreign currency instrument whose performance the manager is trying to duplicate. For example, investing in a combination of U.S. dollar-denominated instruments with “long” forward currency exchange contracts creates a position economically equivalent to investing in a money market instrument denominated in the foreign currency itself. Such combined positions are sometimes necessary when the money market in a particular foreign currency is small or relatively illiquid.
While “physical” delivery of Bitcoins as part of a futures contract would certainly be possible it raises regulatory and security issues in today’s environment where the cybercurrency exchanges are mostly unregulated, somewhat unreliable, and theft due to security hacks is distressingly common.  By selecting cash settlement the CME and Cboe completely avoid the transfer of custody issues and shift those problems to somebody else—namely the market makers and arbitrageur.

I have worked with the CME in the past on product development (specifically CDS futures) and from my experience, they would not have missed anything this simple.  In fact, while I am not a huge fan of the concept of Bitcoin futures, as currently implemented, I do not expect any errors in the operation of the CME or CBOE futures contract.  I am sure that regulators will be questioning them on the back of the OKEX, as they should, and I am also quite positive the exchanges here will pass with flying colors.
Bitcoin has been on a tear this year, surging at least 1,000 percent in 2017. As the cryptocurrency gained even more attention from investors recently, the Commodity Futures Trading Commission announced on Friday that it would allow the CME and Cboe to launch bitcoin futures. The Cboe plans to launch on Dec. 10 and the CME intends to launch on Dec. 18.

Daily Position Limit Risk - Many U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the trading day. In addition, these exchanges have established limits on the maximum amount of futures positions that any person may hold or control on such exchanges. These limits may restrict the amount of assets the Fund is able to invest in bitcoin futures contracts or have a

The question is: Do we live in a society, or do we just have a list of prices and you decide which ones to pay? Do we all try to get along together and share the world, giving due consideration to each other's needs, or do rich people just get to do whatever they want? Much of the article is devoted to the cool things that the Flatiron Institute is doing, but much of it is devoted to people fretting that there might be a downside to rich individuals determining the direction of basic science and using their money to crowd out traditional universities. Meanwhile Simons sits back and smokes and tosses pennies into the no-smoking jar.
In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[38] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[38] With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[38][39]

In 1983 the American cryptographer David Chaum conceived an anonymous cryptographic electronic money called ecash.[9][10] Later, in 1995, he implemented it through Digicash,[11] an early form of cryptographic electronic payments which required user software in order to withdraw notes from a bank and designate specific encrypted keys before it can be sent to a recipient. This allowed the digital currency to be untraceable by the issuing bank, the government, or a third party.
DTC has advised the Trust as follows: it is a limited-purpose trust company organized under the laws of the State of New York, a member of the Federal Reserve System, a “clearing corporation” within the meaning of the New York Uniform Commercial Code and a “clearing agency” registered pursuant to the provisions of Section 17A of the 1934 Act. DTC was created to hold securities of its participants (“DTC Participants”) and to facilitate the clearance and settlement of securities transactions among the DTC Participants in such securities through electronic book-entry changes in accounts of the DTC Participants, thereby eliminating the need for physical movement of securities certificates. DTC Participants include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations, some of whom (and/or their representatives) own DTC. More specifically, DTC is owned by a number of its DTC Participants and by the NYSE and the Financial Industry Regulatory Authority, Inc. Access to the DTC system is also available to others such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a DTC Participant, either directly or indirectly (“Indirect Participants”). DTC agrees with and represents to DTC Participants that it will administer its book-entry system in accordance with its rules and by-laws and requirements of law. Beneficial ownership of Shares is limited to DTC Participants, Indirect Participants and persons holding interests through DTC Participants and Indirect Participants. Ownership of beneficial interests in Shares (owners of such beneficial interests are referred to herein as “Beneficial owners”) is shown on, and the transfer of ownership is effected only through, records maintained by DTC (with respect to DTC Participants) and on the records of DTC Participants (with respect to Indirect Participants and Beneficial owners that are not DTC Participants). Beneficial owners will receive from or through the DTC Participant a written confirmation relating to their purchase of Shares. The laws of some jurisdictions may require that certain purchasers of securities take physical delivery of such securities in definitive form. Such laws may impair the ability of certain investors to acquire beneficial interests in Shares.
  •   Lack of liquid markets, and possible manipulation of blockchain-based assets. Digital assets that are represented and trade on a blockchain may not necessarily benefit from viable trading markets. Stock exchanges have listing requirements and vet issuers, and perhaps users. These conditions may not necessarily be replicated on a blockchain, depending on the platform’s controls and other policies. The more lenient a blockchain is about vetting issuers of digital assets or users that transact on the platform, the higher the potential risk for fraud or the manipulation of digital assets. These factors may decrease liquidity or volume, or increase volatility of digital securities or other assets trading on a blockchain.

Fixed margin will isolate your margin to the individual position you have made in an instrument. So if you have 1 bitcoin in your account and you put 0.2btc margin for a Weeklies Futures long position, and it gets margin-called, you still have the 0.8btc left. However, if you're on cross-margin, also known as portfolio value margin, then your whole balance on the site is going to be used to back all your positions, and if you get margincalled, it's because you have run out of money on your whole account.
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.
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.
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.
The Officers, under the supervision of the Board, manage the day-to-day operations of the Trust. One Trustee and all of the Officers of the Trust are directors, officers or employees of ProShare Advisors or Foreside Management Services, LLC. The other Trustees are Independent Trustees. The Trustees and some Officers are also directors and officers of some or all of the other funds in the Fund Complex. The Fund Complex includes all funds advised by ProShare Advisors and any funds that have an investment adviser that is an affiliated person of ProShare Advisors.
On March 18, 2013, the Financial Crimes Enforcement Network (“FinCEN”) a bureau of the US Department of the Treasury, issued interpretive guidance relating to the application of the Bank Secrecy Act to distributing, exchanging and transmitting “virtual currencies.” More specifically, it determined that a user of virtual currencies (such as bitcoin) for its own account will not be considered a money service business (“MSB”) or be required to register, report and perform recordkeeping; however, an administrator or exchanger of virtual currency must be a registered money services business under FinCEN’s money transmitter regulations. As a result, Bitcoin Exchanges that deal with U.S. residents or otherwise fall under U.S. jurisdiction are required to obtain licenses and comply with FinCEN regulations. FinCEN released additional guidance clarifying that, under the facts presented, miners acting solely for their own benefit, software developers, hardware manufacturers, escrow service providers and investors in bitcoin would not be required to register with FinCEN on the basis of such activity alone, but that Bitcoin Exchanges, certain types of payment processors and convertible digital asset administrators would likely be required to register with FinCEN on the basis of the activities described in the October 2014 and August 2015 letters. FinCEN has also taken significant enforcement steps against companies alleged to have violated its regulations, including the assessment in July 2017 of a civil money penalty in excess of $110 million against BTC-e for alleged willful violation of U.S. anti-money laundering laws.

Certain U.S. government securities are issued or guaranteed by agencies or instrumentalities of the U.S. government including, but not limited to, obligations of U.S. government agencies or instrumentalities, such as the Federal National Mortgage Association (“Fannie Mae” or “FNMA”), the Government National Mortgage Association (“Ginnie Mae” or “GNMA”), the Small Business Administration, the Federal Farm Credit Administration, Federal Home Loan Banks, Banks for Cooperatives (including the Central Bank for Cooperatives), Federal Land Banks, Federal Intermediate Credit Banks, the Tennessee Valley Authority, the Export-Import Bank of the United States, the Commodity Credit Corporation, the Federal Financing Bank, the Student Loan Marketing Association, the National Credit Union Administration and the Federal Agricultural Mortgage Corporation. Some obligations issued or guaranteed by U.S. government agencies and instrumentalities, including, for example, GNMA pass-through certificates, are supported by the full faith and credit of the U.S. Treasury. Other obligations issued by or guaranteed by federal agencies, such as those securities issued by FNMA, are supported by the discretionary authority of the U.S. government to purchase certain obligations of the federal agency but are not backed by the full faith and credit of the U.S. government, while other obligations issued by or guaranteed by federal agencies, such as those of the Federal Home Loan Banks, are supported by the right of the issuer to borrow from the U.S. Treasury. While the U.S. government provides financial support to such U.S. government-sponsored federal agencies and instrumentalities described above, no assurance can be given that the U.S. government will always do so, since the U.S. government is not so obligated by law. U.S. Treasury notes and bonds typically pay coupon interest semi-annually and repay the principal at maturity. All U.S. government securities are subject to credit risk.
•   Dividends paid to a shareholder that is not a “United States person” within the meaning of the Code (such a shareholder, a “foreign person”) that a Fund properly reports as capital gain dividends, short-term capital gain dividends or interest -related dividends, each as further defined in the SAI, are not subject to withholding of U.S. federal income tax, provided that certain other requirements are met. A Fund (or intermediary, as applicable) is permitted, but is not required, to report any part of its dividends as are eligible for such treatment. A Fund’s dividends other than those the Fund properly reports as capital gain dividends, short-term capital gain dividends or interest-related dividends generally will be subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate). Special tax considerations may apply to foreign persons investing in the Fund. Please see the SAI for more information.

When a new crypto is launched, its founders announce how many coins will be mined. Once the quota is reached, no further coins can be produced. The first digital coin introduced was Bitcoin, which remains today the benchmark for all other digital coins. Among other currencies that have made their way into the cryptocurrency hall-of-fame we have: Ethereum, Ripple, Litecoin, EOS, and a number of derived currencies, including Bitcoin Cash and Bitcoin Gold.

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.
Knowing their estimated costs and profit requirements the arbitrageur determines a minimum difference they need between the futures’ prices and the spot price before they will enter the market. They then monitor the price difference between Bitcoin futures and the Bitcoin exchanges and if large enough they act to profit on that gap.  For example, if a specific Bitcoin future (e.g., February contract) is trading sufficiently higher than the current Bitcoin exchange price they will short that Bitcoin future and hedge their position by buying Bitcoins on the exchange. At that point, if they have achieved trade prices within their targets, they have locked in a guaranteed profit. They will hold those positions until contract expiration (or until they can cover their short futures and sell Bitcoins at a profit).
