Bitcoin Gold (BTG) is the second fork from Bitcoin (i.e. the second version to stem from Bitcoin’s source code). It retains Bitcoin’s transaction history, meaning that if you owned Bitcoin before the fork, you now own the equal amount of Bitcoin Gold. This cryptocurrency aims to introduce an alternative mining algorithm that is less susceptible to ASIC-based optimization, therefore allowing users to earn more with their computer cycles.
•   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.
The Funds may enter into forward contracts to attempt to gain exposure to an index or asset without actually purchasing such asset, or to hedge a position. Forward contracts are two-party contracts pursuant to which one party agrees to pay the counterparty a fixed price for an agreed-upon amount of an underlying asset or the cash value of the underlying asset at an agreed-upon date. When required by law, a Fund will segregate liquid assets in an amount equal to the value of the Fund’s total assets committed to the consummation of such forward contracts. Obligations under forward contracts so covered will not be considered senior securities for purposes of a Fund’s investment restriction concerning senior securities. Forward contracts that cannot be terminated in the ordinary course of business within seven days at approximately the amount at which a Fund has valued the asset may be considered to be illiquid for purposes of the Fund’s illiquid investment limitations. A Fund will not enter into a forward contract unless the Advisor believes that the other party to the transaction is creditworthy. The counterparty to any forward contract will typically be a major, global financial institution. A Fund bears the risk of loss of the amount expected to be received under a forward contract in the event of the default or bankruptcy of a counterparty. If such a default occurs, a Fund will have contractual remedies pursuant to the forward contract, but such remedies may be subject to bankruptcy and insolvency laws, which could affect the Fund’s rights as a creditor. The Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF may each invest in forward contracts where commodities are the underlying asset.
Because of the wide range of types and maturities of corporate debt securities, as well as the range of creditworthiness of its issuers, corporate debt securities have widely varying potentials for return and risk profiles. For example, commercial paper issued by a large established domestic corporation that is rated investment-grade may have a modest return on principal, but carries relatively limited risk. On the other hand, a long-term corporate note issued by a small foreign corporation from an emerging market country that has not been rated may have the potential for relatively large returns on principal, but carries a relatively high degree of risk.
Homero Josh Garza, who founded the cryptocurrency startups GAW Miners and ZenMiner in 2014, acknowledged in a plea agreement that the companies were part of a pyramid scheme, and pleaded guilty to wire fraud in 2015. The U.S. Securities and Exchange Commission separately brought a civil enforcement action against Garza, who was eventually ordered to pay a judgment of $9.1 million plus $700,000 in interest. The SEC's complaint stated that Garza, through his companies, had fraudulently sold "investment contracts representing shares in the profits they claimed would be generated" from mining.[88]
An Authorized Participant may place an order to purchase (or redeem) Creation Units (i) through the Continuous Net Settlement clearing processes of NSCC as such processes have been enhanced to effect purchases (and redemptions) of Creation Units, such processes being referred to herein as the “Clearing Process,” or (ii) outside the Clearing Process, though orders for Global Funds (as defined below) may not be placed through the Clearing Process. In either case, a purchase order for a Fund must be received by the following cut-off times (which may be earlier if the relevant Exchange or any relevant bond market closes early). In all cases purchase/redeem procedures are at the discretion of the Advisor and may be changed without notice.
The equity markets are volatile, and the value of securities, swaps, futures, and other instruments correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks in the Index may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.
(c) distribute with respect to each taxable year at least 90% of the sum of its investment company taxable income (as that term is defined in the Code without regard to the deduction for dividends paid—generally, taxable ordinary income and the excess, if any, of net short-term capital gains over net long-term capital losses) and net tax-exempt interest income, for such year.
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.
For example, a Fund may cover its long position in a futures contract by purchasing a put option on the same futures contract with a strike price (i.e., an exercise price) as high as or higher than the price of the futures contract, or, if the strike price of the put is less than the price of the futures contract, the Fund will earmark/segregate cash or liquid instruments equal in value to the difference between the strike price of the put and the price of the future. A Fund may also “cover” its long position in a futures contract by taking a short position in the instruments underlying the futures contract, or by taking positions in instruments whose prices are expected to move relatively consistently, with a short position in the futures contract. A Fund may “cover” its short position in a futures contract by purchasing a call option on the same futures contract with a strike price (i.e., an exercise price) as low as or lower than the price of the futures contract, or, if the strike price of the call is greater than the price of the futures contract, the Fund will earmark /segregate cash or liquid instruments equal in value to the difference between the strike price of the call and the price of the future. A Fund may also “cover” its short position in a futures contract by taking a long position in the instruments underlying the futures contract, or by taking positions in instruments whose prices are expected to move relatively consistently with a long position in the futures contract.
Bitcoin futures promise more flexibility for investors and potentially a more stable price. Yet, there is a chance that volatility could increase in the interim and while strategies like shorting and using leverage hold a lot of potential when used within the right infrastructure, they can be detrimental to smaller investors and, in the worst case scenario, could derail the market in dangerous ways.

The CME Bitcoin futures contracts will be cash-settled, meaning that you will receive USD on the expiration date if your speculation was successful and you have not sold the derivative before the expiration date. You will not receive Bitcoin – that would be a physical settlement, even though Bitcoin is not a physical asset. This is a crucial difference because it enables traders to trade in Bitcoin futures without having a cryptocurrency wallet. Every transaction is done in USD.Thus, it is easy for mainstream traders to take part in this market.

However, many of these investors are still waiting to be convinced to take the leap into crypto. One thing that is still giving many institutional investors pause is the fact that trade management systems in the crypto world simply do not offer the sophistication they are used to in conventional trading. They’ve become accustomed to the support of reliable automated tools, and the prospect of working without those can be a serious roadblock.

No Independent Trustee (or an immediate family member thereof) during the two most recently completed calendar years had: (i) any material interest, direct or indirect, in any transaction or series of similar transactions, in which the amount involved exceeded $120,000; or (ii) any direct or indirect relationship of any nature, in which the amount involved exceeded $120,000, with:
There are also tax risks associated with investments in MLPs. While there are benefits to MLPs that are treated as partnerships for federal income tax purposes, a change to current tax law or in the underlying business of a given MLP could result in the MLP being treated as a corporation for federal income tax purposes. If the MLP were treated as a corporation, the MLP would be required to pay federal income tax on its taxable income, which would reduce the amount of cash available for distribution by the MLP. In addition, because MLPs generally conduct business in multiple states, the Fund may be subject to income or franchise tax in each of the states in which the partnership does business. The additional cost of preparing and filing the tax returns and paying related taxes may adversely impact the Fund’s return.
Let’s say Larry owns one bitcoin and the current price is $16,600, be believes the price is overdone to the upside for a short period of time.  This is a fictional example, so don’t beat me up on the outlook, you can criticize Larry, but he’s made up too.  Larry has a futures account and sees that he can sell short a January XBT Future at $17,600.  He decides to do this and is now short 1 January XBT Future at $17,600. 
If the price drops to $500, you earn 11.73 BTC on the position and have 20.06 BTC left, which at $500 per BTC is worth $10,000! This is a simple example just to show you, even if you're a small bitcoin holder, bitcoin futures are a valuable risk management tool. You could have performed this "hedge" at 50x leverage by putting down just 8.33/50= 0.17 BTC worth of margin!
(b) diversify its holdings so that, at the end of each quarter of a Fund’s taxable year (or by the end of the 30-day period following the close of such quarter), (i) at least 50% of the fair market value of the Fund’s assets is represented by cash and cash items (including receivables), U.S. government securities, the securities of other RICs and other securities, with such other securities limited, in respect of any one issuer, to a value not greater than 5% of the value of the Fund’s total assets and to an amount not greater than 10% of the outstanding voting securities of such issuer, and (ii) not greater than 25% of the value of its total assets is invested, including through corporations in which the Fund owns a 20% or more voting stock interest, in (x) the securities (other than U.S. government securities and the securities of other RICs) of any one issuer or of two or more issuers that the Fund controls and that are engaged in the same, similar or related trades or businesses, or (y) the securities of one or more qualified publicly traded partnerships (as defined below); and
Hey, Will, I like this! Thanx for the info. I’m somewhat new to cryptos but not to investing — my Dad invested in the stock market since I was a kid and as an adult I was a registered investment advisor representative for a large US institution. One conclusion I’ve come to is that the skills and approach for crypto investing are no different than those for the stock market. I use the same strategies and analyses I use for stocks and etf’s and feel completely at home in the crypto market. Yes, I deal with more brokerage accounts, etc., but the principles are the same.
If I held the opinion that an asset was going to go one way, but then made the research and it turned out that I started thinking it might actually be headed the other way, I should feel no obligation to hold on to my original opinion, just because I didnt want to feel I’ve been initially wrong. This seems obvious but is much tougher in practice for inexperienced investors.
When you are getting started making actual trades, in general you should focus on making LIMIT ORDERS which will get FILLED by other traders. Not only will you pay lower fees this way, but you will also be making more composed trading setups because you aren't impatiently just market-buying or market-selling into the spread. So a general principle you should follow is to AVOID MARKET ORDERS WHEN YOU CAN! You will pay higher "taker" fees and you will be at the mercy of the spread which is a hidden fee.

Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described below under “Purchase and Issuance of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor also acts as agent for the Trust. The Distributor will deliver a Prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority, Inc. The Distributor has no role in determining the investment policies of the Funds or which securities are to be purchased or sold by the Funds.
The NAV per share of each Fund is computed by dividing the value of the net assets of such Fund (i.e., the value of its total assets less total liabilities) by its total number of Fund shares outstanding. Expenses and fees are accrued daily and taken into account for purposes of determining NAV. The NAV of each Fund is calculated by JPMorgan Chase Bank, National Association. The NAV of each Fund is generally determined each business day at the close of regular trading of the                    (ordinarily 3:00 p.m. Eastern time). The Fund’s investments 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. In addition, routine valuation of certain other derivatives is performed using procedures approved by the Board.
Like all investments, investing in any of the Funds entails risks. The risk factors most likely to have a significant impact on a Fund’s portfolio are called “principal risks.” The principal risks of each Fund are described in the applicable Fund’s Summary Prospectus and additional information regarding certain of these principal risks, as well as information related to other potential risks to which a particular Fund may be subjected, is provided below. Some risks apply to all of the Funds, while others are specific to the investment strategies of certain Funds, as indicated below. Each Fund may be subject to other risks in addition to those identified as principal risks.
The price of bitcoin has been subject to periods of high volatility. As a result, the CFE and CME have established margin requirements for bitcoin futures contracts at levels substantially higher than the margin requirements for more established futures contracts. The increased margin requirements may result in much higher upfront costs for the Funds. Market participants may be deterred from incorporating bitcoin futures contracts into their investment strategies due to these higher costs and other limitations created by the high margin requirements, such as the limit on their ability to use leverage to invest in bitcoin futures contracts. A reduction in the adoption of the bitcoin futures contracts will negatively impact the market for bitcoin futures contracts and could negatively impact the performance of the Funds. In addition, the continued volatility in the price of bitcoin may result in further increases to the margin requirements for bitcoin futures contracts by the CFE and CME, as well as some FCMs imposing margin requirements on their customers in amounts that are steeper than the margin required by the exchanges.
The equity markets are volatile, and the value of securities, swaps, futures, and other instruments correlated with the equity markets may fluctuate dramatically from day-to-day. Equity markets are subject to corporate, political, regulatory, market and economic developments, as well as developments that impact specific economic sectors, industries or segments of the market. Further, stocks in the Index may underperform other equity investments. Volatility in the markets and/or market developments may cause the value of an investment in the Fund to decrease.
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.
The Board has not adopted a policy of monitoring for frequent purchases and redemptions of shares that appear to attempt to take advantage of potential arbitrage opportunities. The Board believes this is appropriate because ETFs, such as the Funds, are intended to be attractive to arbitrageurs, as trading activity is critical to ensuring that the market price of Fund shares remains at or close to NAV.
In order to qualify for the withholding exemptions for interest-related and short term capital gain dividends, a foreign shareholder is required to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing the applicable W-8 form or substitute form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports all or a portion of a payment as an interest-related or short-term capital gain dividend to shareholders. Foreign shareholders should consult their tax advisors or intermediaries, as applicable, regarding the application of these rules to their accounts.

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.
The first timestamping scheme invented was the proof-of-work scheme. The most widely used proof-of-work schemes are based on SHA-256 and scrypt.[18] The latter now dominates over the world of cryptocurrencies, with at least 480 confirmed implementations.[37] Some other hashing algorithms that are used for proof-of-work include CryptoNight, Blake, SHA-3, and X11.
Distributions by a Fund to a shareholder that is not a “United States person” within the meaning of the Code (such a shareholder, a “foreign shareholder”) properly reported by the Fund as (1) Capital Gain Dividends, (2) short-term capital gain dividends, and (3) interest-related dividends, each as defined and subject to certain conditions described below, generally are not subject to withholding of U.S. federal income tax.

The foregoing discussion is primarily a summary of certain U.S. federal income tax consequences of investing in a Fund based on the law in effect as of the date of this SAI. The discussion does not address in detail special tax rules applicable to certain classes of investors, such as, among others, IRAs and other retirement plans, tax-exempt entities, foreign investors, insurance companies, banks and other financial institutions, and investors making in-kind contributions to a Fund. Such shareholders may be subject to U.S. tax rules that differ significantly from those summarized above. You should consult your tax advisor for more information about your own tax situation, including possible other federal, state, local and, where applicable, foreign tax consequences of investing in a Fund.
Cryptocurrencies allow traders to diversify their investment portfolio, as their price is mainly determined by demand and supply; Their value has a low correlation to national economies or political scenarios. Once Bitcoin surpassed the price of gold in 2017, US markets introduced 2 ETFs on Bitcoin and drew more and more institutional money into the world of cryptocurrencies. In 2017, Indian PM Narendra Modi has announced the gradual replacement of paper currency with electronic currency; In March 2018, the Marshall Islands announced that they would be introducing a cryptocurrency to replace US dollars as their main currency; other central banks are investigating the adoption of blockchain-like technologies… in short cryptocurrencies are probably here to stay. A growing number of crypto investors all over the world have already discovered the benefits:
Additions such as Zerocoin have been suggested, which would allow for true anonymity.[54][55][56] In recent years, anonymizing technologies like zero-knowledge proofs and ring signatures have been employed in the cryptocurrencies Zcash and Monero, respectively. Cryptocurrency anonymizing implementations such as Cloakcoin, Dash, and PIVX use built in mixing services, also known as tumblers.[57]
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.
•	 	Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.

and other factors. Thus, to the extent a Fund invests in swaps that use an ETF as the reference asset, that Fund may be subject to greater correlation risk and may not achieve as high a degree of correlation with its index as it would if the Fund used only swaps on the underlying index. The Advisor, under the supervision of the Board of Trustees, is responsible for determining and monitoring the liquidity of the Funds’ transactions in swap agreements.
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.
fluctuations in the value of the foreign currency between the acquisition and disposition of the position also are treated as ordinary income or loss. In certain circumstances, a Fund may elect to treat foreign currency gain or loss attributable to a forward contract, a futures contract or an option as capital gain or loss. Furthermore, foreign currency gain or loss arising from certain types of section 1256 contracts is treated as capital gain or loss, although a Fund may elect to treat foreign currency gain or loss from such contracts as ordinary in character. These gains and losses, referred to under the Code as “section 988” gains or losses, increase or decrease the amount of a Fund’s investment company taxable income available (and required) to be distributed to its shareholders as ordinary income. If a Fund’s section 988 losses exceed other investment company taxable income during a taxable year, the Fund would not be able to make any ordinary dividend distributions, or distributions made before the losses were realized would be recharacterized as a return of capital to shareholders, rather than as ordinary dividends, thereby reducing each shareholder’s basis in his or her Fund Shares.
Now, if that margin-call does not get filled and the price continues to fall, then I'm making profits on my contract but nobody is paying for it since the counterparty who got margin-called didn't get the liquidation order filled. So what happens is that at settlement time of the contract, that unfilled liquidation loss to the system will be deducted from the profits of ALL traders before they are distributed.

“One of the biggest issues when it comes to investing institutionally in digital assets is banks and larger institutions can’t hold an unregulated instrument in their balance sheet, and a futures contract is something they can hold,” said Gabor Gurbacs, director of digital-asset strategy at VanEck Associates Corp. With futures, “you don’t hold the physical bitcoin, which solves custody issues and counterparty risks with these less-regulated exchanges.”

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

You could imagine the spread going the other way, though. If everyone really was clamoring to short bitcoin, and if the futures offered a more convenient way to do it than the bitcoin exchanges, then you'd expect the short sellers to pay a premium to short via futures. Instead of selling a bitcoin at $18,000 today, they'd be willing to sell a synthetic bitcoin for $17,500, paying the spread to an arbitrageur who was willing to do the actual shorting for them. But the fact that the spread is mostly positive, and that bitcoin's price has been mostly going up, suggests that the demand has mostly been for synthetic long positions, not short.
If SupermegahedgefundX can offset any potential losses with futures trading, then maybe it will be more willing to buy bitcoin – although why it would allow its potential gains to be reduced with the same futures trade is beyond me. And, why hold the bitcoin when you can get similar profits with less initial outlay just by trading the synthetic derivatives?
