Institutional markets for restricted securities have developed as a result of the promulgation of Rule 144A under the 1933 Act, which provides a safe harbor from 1933 Act registration requirements for qualifying sales to institutional investors. When Rule 144A securities present an attractive investment opportunity and otherwise meet selection criteria, a Fund may make such investments. Whether or not such securities are illiquid depends on the market that exists for the particular security. The staff of the SEC has taken the position that the liquidity of Rule 144A restricted securities is a question of fact for a board of trustees to determine, such determination to be based on a consideration of the readily-available trading markets and the review of any contractual restrictions.
AvaTrade offers all traders the opportunity to trade a wide range of top-ranked digital coins 24/7. Due to the massive popularity of cryptocurrencies over the past couple of years, they have become a conventional and popular asset. The main purpose of this new technology is to allow people to buy, trade and invest without having to rely on banks or any other financial institutions.
Securities (including short-term securities) and other assets are generally valued at their market value using information provided by a pricing service or market quotations. Short-term securities are valued on the basis of amortized cost or based on market prices. Futures contracts and options on securities, indexes and futures contracts are generally valued at their last sale price prior to the time at which the NAV per share of a class of shares of a Fund is determined. Alternatively, fair valuation procedures as described below may be applied if deemed more appropriate. Routine valuation of certain other derivatives is performed using procedures approved by the Board of Trustees.
To purchase or redeem through the Clearing Process, an Authorized Participant must be a member of NSCC that is eligible to use the Continuous Net Settlement system. For purchase orders placed through the Clearing Process, the Authorized Participant Agreement authorizes the Distributor to transmit through the Funds’ transfer agent (the “Transfer Agent”) to NSCC, on behalf of an Authorized Participant, such trade instructions as are necessary to effect the Authorized Participant’s purchase order. Pursuant to such trade instructions to NSCC, the Authorized Participant agrees to deliver the requisite Deposit Securities and the Balancing Amount to the Trust, together with the Transaction Fee and such additional information as may be required by the Distributor.
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.
  •   Large-Cap Company Investment Risk —The Fund invests in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.
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.
The Declaration of Trust of the Trust disclaims liability of the shareholders or the Officers of the Trust for acts or obligations of the Trust which are binding only on the assets and property of the Trust. The Declaration of Trust provides for indemnification of the Trust’s property for all loss and expense of any Funds shareholder held personally liable for the obligations of the Trust. The risk of a Trust shareholder incurring financial loss on account of shareholder liability is limited to circumstances where the Funds would not be able to meet the Trust’s obligations and this risk, thus, should be considered remote.
Kraken’s innovative features claim to cater to the demand of fast execution, outstanding support and high security. The organisation is based in San Francisco, USA. Kraken is operational worldwide with a pre-validation for those countries where it is not eligible. The platform accepts both Cryptocurrency and fiat and transaction is completed by a wire transfer which should be completed at the bank. The platform does not accept debit, credit or cash.
  •   Bitcoin is available for trading 24-hours a day globally and, as such, the price of bitcoin may change dramatically when the market for bitcoin futures contracts is closed or when Fund shares are not available for trading on the Exchange. The price of bitcoin may change dramatically at times when investors are unable to buy or sell Fund shares.
* The “Fund Complex” consists of all operational registered investment companies under the 1940 Act that are advised by ProShare Advisors LLC and any registered investment companies that have an investment adviser that is an affiliated person of ProShare Advisors LLC. Investment companies that are non-operational (and therefore, not publicly offered) as of the date of this SAI are excluded from these figures.
•   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 ProShares 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.
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.

The tax treatment of certain contracts (including regulated futures contracts and non-equity options) entered into by the Fund will be governed by Section 1256 of the Code (“Section 1256 contracts”). Gains (or losses) on these contracts generally are considered to be 60% long-term and 40% short-term capital gains or losses (“60/40”), although foreign currency gains or losses arising from certain Section 1256 contracts may be treated as ordinary in character (see “Foreign Currency Transactions” below). Also, section 1256 contracts held by a Fund at the end of each taxable year (and for purposes of the 4% excise tax, on certain other dates prescribed in the Code) are “marked-to-market” with the result that unrealized gains or losses are treated as though they were realized and the resulting gains or losses are treated as ordinary or 60/40 gains or losses, as appropriate.
Futures contracts with a longer term to expiration may be priced higher than futures contracts with a shorter term to expiration, a relationship called “contango.” Conversely, futures contracts with a longer term to expiration may be priced lower than futures contracts with a shorter term to expiration, a relationship called “backwardation.” Contango and backwardation have different impacts on ProShares Bitcoin/Blockchain ProShares Bitcoin Futures Strategy ETF, ProShares Bitcoin Futures/Equity Strategy ETF and ProShares Bitcoin/Blockchain Strategy ETF (each, a “Bitcoin Fund”) and ProShares Short Bitcoin Futures Strategy ETF (the “Short Bitcoin Fund”).
DTC may determine to discontinue providing its service with respect to Shares at any time by giving reasonable notice to the Trust and discharging its responsibilities with respect thereto under applicable law. Under such circumstances, the Trust shall take action either to find a replacement for DTC to perform its functions at a comparable cost or, if such a replacement is unavailable, to issue and deliver printed certificates representing ownership of Shares, unless the Trust makes other arrangements with respect thereto satisfactory to the Exchange. In addition, certain brokers may make a dividend reinvestment service available to their clients. Brokers offering such services may require investors to adhere to specific procedures and timetables in order to participate. Investors interested in such a service should contact their broker for availability and other necessary details.
Each Fund may purchase illiquid securities, including securities that are not readily marketable and securities that are not registered (“restricted securities”) under the Securities Act of 1933 (the “1933 Act”), but which can be sold to qualified institutional buyers under Rule 144A under the 1933 Act. A Fund will not invest more than 15% of the Fund’s net assets in illiquid securities. The term “illiquid securities” for this purpose means securities that cannot be disposed of within seven days in the ordinary course of business at approximately the amount at which the Fund has valued the securities. Under the current guidelines of the staff of the SEC, illiquid securities also are considered to include, among other securities, purchased OTC options, certain cover for OTC options, repurchase agreements with maturities in excess of seven days, and certain securities whose disposition is restricted under the federal securities laws. The Fund may not be able to sell illiquid securities when the Advisor considers it desirable to do so or may have to sell such securities at a price that is lower than the price that could be obtained if the securities were more liquid. In addition, the sale of illiquid securities also may require more time and may result in higher dealer discounts and other selling expenses than the sale of securities that are not illiquid. Illiquid securities may be more difficult to value due to the unavailability of reliable market quotations for such securities, and investments in illiquid securities may have an adverse impact on NAV.
Coinbase is not alone in making moves toward becoming an ATS. Recently, mobile payment app company Circle acquired Poloniex, another U.S.-based exchange, with plans to “clean up” the exchange. A slide that was initially leaked from a Circle presentation stated, “Circle has briefed the SEC on the transaction and indicated that upon closing that we will begin the process of registering the new entity with the SEC and FINRA as a Broker/Dealer and in turn as a licensed ATS…”
Creation Units of Shares may be purchased only by or through a DTC Participant that has entered into an Authorized Participant Agreement with the Distributor. Such Authorized Participant will agree pursuant to the terms of such Authorized Participant Agreement on behalf of itself or any investor on whose behalf it will act, as the case may be, to certain conditions, including that such Authorized Participant will make available an amount of cash sufficient to pay the Balancing Amount, defined below, and the Transaction Fee, described below in “Transaction Fees”. The Authorized Participant may require the investor to enter into an agreement with such Authorized Participant with respect to certain matters, including payment of the Balancing Amount. Investors who are not Authorized Participants must make appropriate arrangements with an Authorized Participant. Investors should be aware that their particular broker may not be a DTC Participant or may not have executed an Authorized Participant Agreement, and that therefore orders to purchase Creation Units may have to be placed by the investor’s broker through an Authorized Participant. As a result, purchase orders placed through an Authorized Participant may result in additional charges to such investor. The Trust does not expect to enter into an Authorized Participant Agreement with more than a small number of DTC Participants.
All other procedures set forth in the Authorized Participant Agreement must be followed in order to receive the next determined NAV. The requisite Fund Securities and the Balancing Amount (minus a redemption Transaction Fee or additional charges for requested cash redemptions) or the Cash Redemption Amount, as applicable and at the discretion of the Advisor, will be transferred by the second (2nd) NSCC Business Day following the date on which such request for redemption is deemed received. Cash-only redemption orders and Global Fund orders may not be placed through the Clearing Process.

Credit Default Swaps (“CDS”): In the case of a CDS, the agreement will reference one or more debt securities or reference entities. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference entity has occurred. If a credit event occurs, the seller generally must pay the buyer: a) the full notional value of the swap; or b) the difference between the notional value of the defaulted reference entity and the recovery price/rate for the defaulted reference entity. CDS are designed to reflect changes in credit quality, including events of default. The CDS Short North American HY Credit ETF will normally be a “buyer” of CDS (also referred to as a buyer of protection or a seller of risk). The CDS Short North American HY Credit ETF will primarily invest in centrally cleared, index-based CDS that provide credit exposure through a single trade to a basket of reference entities. The CDS Short North American HY Credit ETF may also invest in single-name CDS. Single-name CDS provide exposure to a single reference entity and are not centrally cleared.

"We expect that the futures exchanges, through information sharing agreements, will be monitoring the trading activity on the relevant cash platforms for potential impacts on the futures contracts' price discovery process," CFTC Chair J. Christopher Giancarlo said in an official statement. "This includes potential market manipulation and market dislocations due to flash rallies and crashes and trading outages."
The block time is the average time it takes for the network to generate one extra block in the blockchain.[35] Some blockchains create a new block as frequently as every five seconds.[36] By the time of block completion, the included data becomes verifiable. This is practically when the money transaction takes place, so a shorter block time means faster transactions.[citation needed]

Only invest what you can lose. During the recent crash in January 2018, hobby-investors got burned. Reports of frustration and losses came at the cost of broken monitors, smashed laptops, and heavy monetary losses. While the rules are in more particular order of importance, it’s safe to assume that this is the most important rule, the rule to rule the rules. As soon as your money is converted into cryptocurrency, consider it lost forever. There is absolutely no guarantee you can get it back. Losses don’t simply come from dips in the market; extraordinary factors such as hacks, bugs, and government regulation can mean you’ll never see any of your money again. If you are investing money you can’t afford to lose, you need to take a step back and re-evaluate your current financial situation, because what you’re about to do is an act of desperation. This includes: using credit cards, taking out mortgages, applying for loans, or selling everything and traveling the world (as glamorous as that sounds).

The truth is that bitcoin is the hottest trading market right now, hotter than stock trading, oil trading, gold trading and any other market at this point. The reason people believe this is going to continue to be a hot market is because blockchain technology which is what allows transactions to happen without a central exchange. Here is another strategy on how to draw trend lines with fractals.
Beneficial owners of Shares are not entitled to have Shares registered in their names, will not receive or be entitled to receive physical delivery of certificates in definitive form and are not considered the registered holder thereof. Accordingly, each Beneficial Owner must rely on the procedures of DTC, the DTC Participant and any Indirect Participant through which such Beneficial Owner holds its interests, to exercise any rights of a holder of Shares. The Trust understands that under existing industry practice, in the event the Trust requests any action of holders of Shares, or a Beneficial Owner desires to take any action that DTC, as the record owner of all outstanding Shares, is entitled to take, DTC would authorize the DTC Participants to take such action and that the DTC Participants would authorize the Indirect Participants and Beneficial owners acting through such DTC Participants to take such action and would otherwise act upon the instructions of Beneficial owners owning through them. As described above, the Trust recognizes DTC or its nominee as the owner of all Shares for all purposes. Conveyance of all notices, statements and other communications to Beneficial owners is effected as follows. Pursuant to the Depositary Agreement between the Trust and DTC, DTC is required to make available to the Trust upon request and for a fee to be charged to the Trust a listing of Shares holdings of each DTC Participant. The Trust shall inquire of each such DTC Participant as to the number of Beneficial owners holding Shares, directly or indirectly, through such DTC Participant. The Trust shall provide each such DTC Participant with copies of such notice, statement or other communication, in such
Currently, Bitcoin futures have very high margin requirements. The Cboe requires 40% of the notional amount for maintenance margin, the CME requires 43%. Your broker will likely require more than that. The culprit behind these high requirements is Bitcoin’s high volatility—until that calms down the exchanges will protect themselves by requiring a bunch of up-front money. If you don’t come up with the money for a margin call they want to close out your position without leaving a negative balance.
that receive different proportions of the interest and principal distributions from a pool of mortgage assets. The Funds will only invest in SMBS whose mortgage assets are U.S. government obligations. A common type of SMBS will be structured so that one class receives some of the interest and most of the principal from the mortgage assets, while the other class receives most of the interest and the remainder of the principal. If the underlying mortgage assets experience greater than anticipated prepayments of principal, each Fund may fail to fully recoup its initial investment in these securities. The market value of any class that consists primarily or entirely of principal payments generally is unusually volatile in response to changes in interest rates.
The only way that new Bitcoin can be created is through a process called “mining.” Bitcoin mining occurs when users process transactional data into “blocks” and then add them to the blockchain. As payment for this service, miners are awarded specific amounts of new Bitcoin. Upon its launch, the maximum supply of Bitcoin was predetermined to be 21 million.
If an investor gets the timing of the oscillations right, they can make money at every point along the way, going long when the market goes up and short when it drops. However, it is also difficult to come across any reliable strategy that has thus far been able to predict which events influence the price of bitcoin to which extent. The initial calling off of the Segwit2x fork is a good example of that. Shortly after the news broke, the market appeared to be divided into two camps – those who saw less value because they would not receive the equivalent amount of their holdings in the new currency (“dividends”), and those who saw the news as a consolidation of bitcoin’s strength. The two camps pushed the price in opposite directions in a way that made it hard to predict which side would have the upper hand at which point in time.
Since the introduction of futures, the price of bitcoin has gone up, suggesting that there were more As -- people who wanted to be long bitcoin synthetically -- than Cs -- people who wanted to be short synthetically -- though again it is still early. Crudely speaking, the arbitrage spread suggests that there are also more As than Bs: There are a lot of people who want to be long bitcoin without owning bitcoin, but not so many people who want to own bitcoin without being long bitcoin. (Which makes sense! If you bought a bitcoin and sold a futures contract when Cboe launched its futures last week, you could have locked in a risk-free arbitrage profit of something like $1,200. But if you had just bought a bitcoin, you'd be up about $3,000 by now.) The costs of trading actual bitcoins on bitcoin exchanges -- in terms of blockchain transaction costs, exchange withdrawal limits, etc. -- are significant enough that people who want bitcoin exposure are willing to pay about 2 percent to avoid them.

The Fund expects to gain exposure to bitcoin futures contracts by investing a portion of its assets in a wholly-owned subsidiary of the Fund organized under the laws of the Cayman Islands (the “Subsidiary”). The Subsidiary is not registered under the 1940 Act and, unless otherwise noted in this Prospectus, is not subject to all of the investor protections of the 1940 Act. Thus, the Fund, as the sole investor in the subsidiary, will not have all of the protections offered to shareholders of registered investment companies.
A bitcoin exchange operates somewhat similarly to online stock trading brokers, where customers deposit their fiat currency (or bitcoins) to carry out trades. However, not all bitcoin exchanges offer such services. Some exchanges are more like wallets and thus provide limited trading options or storage of currency (both digital and fiat) for trading. The bigger and more elaborate exchanges offer trades between different cryptocurrencies, as well as between digital and fiat currencies. The number of currencies supported by an exchange varies from one exchange to another. (For more, see: Why Is Bitcoin’s Value So Volatile.)

As of February 2018, the Chinese Government halted trading of virtual currency, banned initial coin offerings and shut down mining. Some Chinese miners have since relocated to Canada.[43] One company is operating data centers for mining operations at Canadian oil and gas field sites, due to low gas prices.[44] In June 2018, Hydro Quebec proposed to the provincial government to allocate 500 MW to crypto companies for mining.[45] According to a February 2018 report from Fortune,[46] Iceland has become a haven for cryptocurrency miners in part because of its cheap electricity. Prices are contained because nearly all of the country’s energy comes from renewable sources, prompting more mining companies to consider opening operations in Iceland. The region’s energy company says bitcoin mining is becoming so popular that the country will likely use more electricity to mine coins than power homes in 2018. In October 2018 Russia will become home to one of the largest legal mining operations in the world, located in Siberia. More than 1.5 million Russians are engaged in home mining. Russia’s energy resources and climate provide some of the best conditions for crypto mining.[47]
The audited Financial Statements, for each Fund that commenced operations prior to May 31, 2017, and the report of PricewaterhouseCoopers LLP, as independent registered public accounting firm, for the fiscal year ended May 31,2017, that appear in the Annual Report to shareholders dated May 31, 2017, are hereby incorporated by reference in this SAI. The Annual Report to shareholders is delivered with this SAI to shareholders requesting this SAI.
The Funds may invest in shares of foreign corporations that are classified under the Code as passive foreign investment companies (“PFICs”). In general, a foreign corporation is classified as a PFIC if at least one-half of its assets constitute investment-type assets, or 75% or more of its gross income is investment-type income. Certain distributions from a PFIC, as well as gain from the sale of PFIC shares, are treated as “excess distributions.” Excess distributions are taxable as ordinary income even though, absent

As discussed in more detail below, FATCA (as defined below) generally imposes a reporting and 30% withholding tax regime with respect to certain U.S.-source income (“withholdable payments”) paid to “foreign financial institutions” and certain other non-U.S. entities when those entities fail to satisfy the applicable account documentation, information reporting, withholding, registration, certification and/or other requirements applicable to their status under FATCA. A Subsidiary will be subject to the 30% withholding tax in respect of any withholdable payment it receives if it fails to satisfy these requirements, as may be applicable to the Subsidiary. Each Subsidiary expects to satisfy these requirements, as may be applicable to it, so as to avoid this additional 30% withholding. See “Certain Additional Reporting and Withholding Requirements” below for more discussion of these rules.
The value of the bitcoin futures contracts is generally based on the expected value of bitcoin at a future point in time, specifically, the expiration date of the bitcoin futures contracts. Other factors, such as cost of mining, storing and securing bitcoin may affect the value of bitcoin futures. A change in the price of bitcoin today (sometimes referred to as the “spot” price) will not necessarily result in a corresponding movement in the price of the bitcoin futures contracts since the price of the bitcoin futures contracts is based on expectations of the price of bitcoin at a future point in time. Additionally, there is no one centralized source for pricing bitcoin and pricing from one bitcoin exchange to the next can vary widely. Therefore, the value of the bitcoin futures contracts held by the Fund should not be expected to track the price of bitcoin on the Bitcoin Exchange Market.

XBT futures are cash-settled contracts based on the Gemini's auction price for bitcoin, denominated in U.S. dollars. Gemini Trust Company, LLC (Gemini) is a digital asset exchange and custodian founded in 2014 that allows customers to buy, sell, and store digital assets such as bitcoin, and is subject to fiduciary obligations, capital reserve requirements, and banking compliance standards of the New York State Department of Financial Services.

All other procedures set forth in the Authorized Participant Agreement must be followed in order to receive the next determined NAV. The requisite Fund Securities and the Balancing Amount (minus a redemption Transaction Fee or additional charges for requested cash redemptions) or the Cash Redemption Amount, as applicable and at the discretion of the Advisor, will be transferred by the second (2nd) NSCC Business Day following the date on which such request for redemption is deemed received. Cash-only redemption orders and Global Fund orders may not be placed through the Clearing Process.
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 Short Bitcoin Futures 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.

Cryptocurrencies have been compared to Ponzi schemes, pyramid schemes[95] and economic bubbles,[96] such as housing market bubbles.[97] Howard Marks of Oaktree Capital Management stated in 2017 that digital currencies were "nothing but an unfounded fad (or perhaps even a pyramid scheme), based on a willingness to ascribe value to something that has little or none beyond what people will pay for it", and compared them to the tulip mania (1637), South Sea Bubble (1720), and dot-com bubble (1999).[98]

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.

Margin Call - when you run out of bitcoin on your account to cover the contract positions you have taken (your account value doesn't cover the Maintance Margin) you are officially rekt. Some exchanges like CryptoFacilities will merely notify you that you have to deposit more or reduce your positions to increase your margin. Others like BitMEX will liquidate you at this level where the exchange takes over your position to liquidate it into the market to prevent system loss.
•   Counterparty Risk —The Fund bears the risk that the counterparty to derivative transaction, such as a futures contract, defaults or otherwise fails to honor its obligations. If a counterparty defaults, the Fund will lose money and the value of an investment in the Fund may decrease. The Fund may engage in futures transactions with a limited number of counterparties, which may increase the Fund’s exposure to counterparty risk. The effect of the volatility of bitcoin pricing or other aspects of trading in bitcoin futures on futures clearinghouses for bitcoin futures is currently unknown, and may result in increased counterparty risk.

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.
“Given increasing client interest in the evolving cryptocurrency markets, we have decided to introduce a bitcoin futures contract,” said Terry Duffy, CME Group Chairman and Chief Executive Officer. He further added, “As the world's largest regulated FX marketplace, CME Group is the natural home for this new vehicle that will provide investors with transparency, price discovery and risk transfer capabilities.”
