Upon a sale, exchange or other disposition of shares of a Fund, a shareholder will generally realize a taxable gain or loss depending upon his or her basis in the shares. A gain or loss will be treated as capital gain or loss if the shares are capital assets in the shareholder’s hands, and generally will be long-term or short-term capital gain or loss depending upon the shareholder’s holding period for the shares. Any loss realized on a sale, exchange or other disposition will be disallowed to the extent the shares disposed of are replaced (including through reinvestment of dividends) within a period of 61 days beginning 30 days before and ending 30 days after the shares are disposed of. In such a case, the basis of the shares acquired will be adjusted to reflect the disallowed loss. Any loss realized by a shareholder on the disposition of a Fund’s Shares held by the shareholder for six months or less will be treated for tax purposes as a long-term capital loss to the extent of any distributions of Capital Gain Dividends received or treated as having been received by the shareholder with respect to such shares.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.

Oops! These guys seem to have had no background in cryptocurrency, which hurt them. If they had raised money from "donors" by selling tokens with no "rights, uses, purpose, attributes, functionalities or features," they'd be fine. But they were used to raising money from investors, so they called the people who bought their tokens "investors." It's a rookie crypto mistake, and one that might cost them all the money they raised.
application of the PFIC rules, certain excess distributions might have been classified as capital gains. In general, under the PFIC rules, an excess distribution is treated as having been realized ratably over the period during which the Fund held the PFIC shares. If a Fund receives an excess distribution with respect to PFIC stock, the Fund will itself be subject to tax on the portion of an excess distribution that is allocated to prior taxable years without the ability to reduce such tax by making distributions to Fund shareholders, and an interest factor will be added to the tax as if the tax had been payable in such prior taxable years.
Each Fund may invest directly in foreign currencies or hold financial instruments that provide exposure to foreign currencies, including “hard currencies,” or may invest in securities that trade in, or receive revenues in, foreign currencies. “Hard currencies” are currencies in which investors have confidence and are typically currencies of economically and politically stable industrialized nations. To the extent that a Fund invests in such currencies, that Fund will be subject to the risk that those currencies will decline in value relative to the U.S. dollar. Currency rates in foreign countries may fluctuate significantly over short periods of time. Fund assets that are denominated in foreign currencies may be devalued against the U.S. dollar, resulting in a loss. Additionally, recent issues associated with the euro may have adverse effects on non-U.S. investments generally and on currency markets. A U.S. dollar investment in Depositary Receipts or ordinary shares of foreign issuers traded on U.S. exchanges may be affected differently by currency fluctuations than would an investment made in a foreign currency on a foreign exchange in shares of the same issuer. Foreign currencies are also subject to risks caused by inflation, interest rates, budget deficits and low savings rates, political factors and government control.
JPMorgan Chase Bank, National Association, One Beacon Street, 19th Floor, Boston, MA 02108, acts as Administrator to the Funds pursuant to an administration agreement dated June 16, 2006, as amended from time to time. The Administrator provides the Funds with all required general administrative services, including, without limitation, office space, equipment, and personnel; clerical and general back office services; bookkeeping and internal accounting; the determination of NAVs; and the preparation and filing of all financial reports, and all other materials, except registration statements and proxy statements, required to be filed or furnished by the Funds under federal and state securities laws. Citi Fund Services Ohio, Inc. (“Citi”), located at 4400 Easton Commons, Suite 200, Columbus, OH 43219, an indirect wholly-owned subsidiary of Citibank N.A., provides regulatory administration services to the Trust (altogether, the “Regulatory Administrative Services”). For its services, Citi is paid a set fee allocated among each of the Funds.
Under current law, income of a RIC that would be treated as UBTI if earned directly by a tax-exempt entity generally will not be attributed as UBTI to a tax-exempt entity that is a shareholder in the RIC. Notwithstanding this “blocking” effect, a tax-exempt shareholder could realize UBTI by virtue of its investment in a Fund if Shares in a Fund constitute debt-financed property in the hands of the tax-exempt shareholder within the meaning of Code section 514(b).

The example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your Shares at the end of each period. The example also assumes that your investment has a 5% return each year and that the Fund’s operating expenses remain the same.

ADRs represent the right to receive securities of foreign issuers deposited in a domestic bank or a correspondent bank. ADRs are an alternative to purchasing the underlying securities in their national markets and currencies. For many foreign securities, U.S. dollar-denominated ADRs, which are traded in the United States on exchanges or over-the-counter (“OTC”), are issued by domestic banks. In general, there is a large, liquid market in the United States for many ADRs. Investments in ADRs have certain advantages over direct investment in the underlying foreign securities because: (i) ADRs are U.S. dollar-denominated investments that are easily transferable and for which market quotations are readily available, and (ii) issuers whose securities are represented by ADRs are generally subject to auditing, accounting and financial reporting standards similar to those applied to domestic issuers. ADRs do not eliminate all risk inherent in investing in the securities of foreign issuers. By investing in ADRs rather than directly in the stock of foreign issuers outside the U.S., however, the Funds may avoid certain risks related to investing in foreign securities on non-U.S. markets.

The moment you look at the amount of support Tron has been receiving lately, you immediately realize it’s not just yet another blockchain-based platform. Tron’s technology aims to deploy world’s largest FREE content entertainment system. The platform allows anyone to store and own data, and to freely publish their content. Its app “Peiwo” already gathers 10 million enthusiasts and is on the road to become the world’s first TRON-compatible entertainment app. This technology revolves around the following ideology:  All contributions on the network should be of equal quantitative value, the Internet should be decentralized, and data creators should have the absolute ownership of the data. It’s important to realise though that Tron has been pushed like hell by an ambitious marketing department… I have not yet decided if this is a cryptocurrency which will survive but, for a one year hold, it seems a safe bet.
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, including potential market manipulation and market dislocations due to flash rallies and crashes and trading outages. Nevertheless, investors should be aware of the potentially high level of volatility and risk in trading these contracts . . . it is incumbent on market participants to conduct appropriate due diligence to determine the particular appropriateness of these products, which at times have exhibited extreme volatility and unique risks.”
Trustees, is of an adequate size to oversee the operations of the Trust, and that, in light of the small size of the Board, a complex Board leadership structure is not necessary or desirable. The relatively small size of the Board facilitates ready communication among the Board members, and between the Board and management, both at Board meetings and between meetings, further leading to the determination that a complex board structure is unnecessary. In view of the small size of the Board, the Board has concluded that designating one of the three Independent Trustees as the “lead Independent Trustee” would not be likely to meaningfully enhance the effectiveness of the Board. The Board reviews its leadership structure periodically and believes that its structure is appropriate to enable the Board to exercise its oversight of the Funds.
Cryptocurrencies are a potential tool to evade economic sanctions for example against Russia, Iran, or Venezuela. In April 2018, Russian and Iranian economic representatives met to discuss how to bypass the global SWIFT system through decentralized blockchain technology.[72] Russia also secretly supported Venezuela with the creation of the petro (El Petro), a national cryptocurrency initiated by the Maduro government to obtain valuable oil revenues by circumventing US sanctions.[73]
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.
Still elsewhere, the Commodity Futures Trading Commission, in a footnote, quoted me saying "Just because you mumble the word 'blockchain' doesn't make otherwise illegal things legal," which I hope is now an official CFTC position. And here is Tyler Cowen on bitcoin volatility and Siegel's paradox: "Volatility is a feature of Bitcoin, not a bug, and that is in part for reasons that have nothing to do with speculation or bubbliness, but rather follow from the contours of the utility function." And: "No, a Guy Didn't Scam $1 Million by Selling Chuck E. Cheese Tokens as Bitcoins."
Various government agencies, departments, and courts have classified bitcoin differently. China Central Bank banned the handling of bitcoins by financial institutions in China in early 2014.[69] In Russia, though cryptocurrencies are legal, it is illegal to actually purchase goods with any currency other than the Russian ruble.[70] Regulations and bans that apply to bitcoin probably extend to similar cryptocurrency systems.[71]

Collateralized mortgage obligations (“CMOs”) are debt obligations collateralized by mortgage loans or mortgage pass-through securities (collateral collectively hereinafter referred to as “Mortgage Assets”). Multi-class pass-through securities are interests in a trust composed of Mortgage Assets and all references in this section to CMOs include multi-class pass-through securities. Principal prepayments on the Mortgage Assets may cause the CMOs to be retired substantially earlier than their stated maturities or final distribution dates, resulting in a loss of all or part of the premium if any has been paid. Interest is paid or accrues on all classes of the CMOs on a monthly, quarterly or semi-annual basis. The principal and interest payments on the Mortgage Assets may be allocated among the various classes of CMOs in several ways. Typically, payments of principal, including any prepayments, on the underlying mortgages are applied to the classes in the order of their respective stated maturities or final distribution dates, so that no payment of principal is made on CMOs of a class until all CMOs of other classes having earlier stated maturities or final distribution dates have been paid in full.

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?

If Bitcoin futures prices get too high relative to spot arbitragers are natural sellers and if the futures prices get too low they are natural buyers. Their buying and selling actions naturally counteract price distortions between markets. If they’re somehow prevented from acting (e.g., if shorting Bitcoin was forbidden) then the futures market would likely become decoupled from the underlying spot price—not a good thing.

The table below shows a performance example of a Short ProShares Fund that has an investment objective to correspond to the inverse (-1x) of the daily performance of an index. In the chart below, areas shaded lighter represent those scenarios where a Short ProShares Fund will return the same or outperform (i.e., return more than) the index performance; conversely, areas shaded darker represent those scenarios where a Short ProShares Fund will underperform (i.e., return less than) the index performance.
As noted above, swap agreements typically are settled on a net basis, which means that the payment streams are netted out, with the Fund receiving or paying, as the case may be, only the net amount of the two payments. Payments may be made at the conclusion of a swap agreement or periodically during its term. The timing and character of any income, gain or loss recognized by a Fund on the payment or payments made or received on a swap will vary depending upon the terms of the particular swap. Swap agreements do not involve the delivery of securities or other underlying assets. Accordingly, the risk of loss with respect to swap agreements is limited to the net amount of payments that a Fund is contractually obligated to make. If the other party to a swap agreement defaults, a Fund’s risk of loss consists of the net amount of payments that such Fund is contractually entitled to receive, if any. The net amount of the excess, if any, of a Fund’s obligations over its entitlements with respect to each swap will be accrued on a daily basis and an amount of cash or liquid assets, having an aggregate NAV at least equal to such accrued excess will be earmarked or segregated by a Fund’s custodian (though, as noted above, in connection with CDS in which a Fund is a “seller”, the Fund will segregate or earmark cash or assets determined to be liquid, with a value at least equal to the full notional amount of the swap (minus any variation margin or amounts owed to the Fund under an offsetting transaction)). Inasmuch as these transactions are entered into for hedging purposes or are offset by earmarked or segregated cash or liquid assets, as permitted by applicable law, the Funds and their Advisor believe that these transactions do not constitute senior securities within the meaning of the 1940 Act, and, accordingly, will not treat them as being subject to a Fund’s borrowing restrictions.
Investors purchasing and selling shares in the secondary market may not experience investment results consistent with those experienced by Authorized Participants creating and redeeming directly with the Fund. To the extent that exchange specialists, market makers, Authorized Participants, or other participants are unavailable or unable to trade the Fund’s shares and/or create or redeem Creation Units, trading spreads and the resulting premium or discount on the Fund’s shares may widen and the Fund’s shares may possibly be subject to trading halts and/or delisting.

XBT futures is a cash-settled contract that settles to a single, tradeable auction price. In designing XBT futures, Cboe leveraged its significant product development expertise to design an instrument that allows participants to implement trading strategies in a manner to which they are accustomed. The single price settlement process gives participants the option of using XBT futures to hedge their exposure in underlying bitcoin or gain exposure to traded bitcoin prices without holding bitcoin.

To seek to achieve its investment objective, as a cash reserve, for liquidity purposes, or as cover for positions it has taken, each Fund may invest all or part of its assets in cash or cash equivalents, which include, but are not limited to, short-term money market instruments, U.S. government securities, certificates of deposit, bankers acceptances, or repurchase agreements secured by U.S. government securities.
The Fund is an actively managed exchange traded fund. The Fund seeks to achieve its investment objective by investing substantially all of its assets in U.S. large capitalization equity securities and bitcoin futures contracts. The Fund is designed to benefit when the prices of U.S. large capitalization equity securities and bitcoin futures contracts increases. The Fund generally seeks to have 70% of the value of its portfolio invested in the equity securities of the 500 largest U.S. public companies and 30% of the value of its portfolio invested in bitcoin futures contracts. The Fund does not invest directly in bitcoin.

Interestingly, the cryptocurrency market seems to rise and fall simultaneously with the altcoins. Is a systemic issue that causes this harmonious rise and fall of prices on the exchanges? The answer is a little fuzzy, but there are several factors at play. Most exchanges use Bitcoin as the universal trading currency, which leads to many investors buying and selling Bitcoin to buy and sell altcoins. When bitcoin starts a bull run, many of the altcoins fall, as investors jump on the Bitcoin train and vice versa. It’s also systemic because most exchanges require Bitcoin rather than fiat currency to transact. It is easy to invest fiat currency in the market and then leave there as an investor trades it; moving it from one currency to another and not cashing it back to fiat currency. Furthermore, When the Bitcoin price falls or rises against the fiat currency, all the altcoins will usually follow. This is because all altcoin prices are based on their Bitcoin exchange rate, not their fiat currency exchange rate. The value of an altcoin in fiat currency is the value of the altcoin in Bitcoin and then Bitcoin’s value in that fiat currency. It is Bitcoin that strongly affects pricing.
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.
Although certain securities exchanges attempt to provide continuously liquid markets in which holders and writers of options can close out their positions at any time prior to the expiration of the option, no assurance can be given that a market will exist at all times for all outstanding options purchased or sold by a Fund. If an options market were to become unavailable, the Fund would be unable to realize its profits or limit its losses until the Fund could exercise options it holds, and the Fund would remain obligated until options it wrote were exercised or expired. Reasons for the absence of liquid secondary market on an exchange include the following: (i) there may be insufficient trading interest in certain options; (ii) restrictions may be imposed by an exchange on opening or closing transactions or both; (iii) trading halts, suspensions or other restrictions may be imposed with respect to particular classes or series of options; (iv) unusual or unforeseen circumstances may interrupt normal operations on an exchange; (v) the facilities of an exchange or the OCC may not at all times be adequate to handle current trading volume; or (vi) one or more exchanges could, for economic or other reasons, decide or be compelled at some future date to discontinue the trading of options (or a particular class or series of options) and those options would cease to exist, although outstanding options on that exchange that had been issued by the OCC as a result of trades on that exchange would continue to be exercisable in accordance with their terms.

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.
Cryptocurrency is also used in controversial settings in the form of online black markets, such as Silk Road. The original Silk Road was shut down in October 2013 and there have been two more versions in use since then. In the year following the initial shutdown of Silk Road, the number of prominent dark markets increased from four to twelve, while the amount of drug listings increased from 18,000 to 32,000.[84]

Over the past several years, a number of Bitcoin Exchanges have been closed due to fraud, failure, security breaches or governmental regulations. The nature of the assets held at Bitcoin Exchanges make them appealing targets for hackers and a number of Bitcoin Exchanges have been victims of cybercrimes. In many of these instances, the customers of such Bitcoin Exchanges were not compensated or made whole for the partial or complete losses of their account balances in such Bitcoin Exchanges. No Bitcoin Exchange is immune from these risks but the existence of these risks has created a higher barrier of entry for new Bitcoin Exchanges. The loss of confidence in new and smaller Bitcoin Exchanges and in the Bitcoin Exchange Market overall can slow down the mass adoption of bitcoin. Further, the failure of the Bitcoin Exchange Market or any other major component of the overall bitcoin ecosystem can have consequences for the Bitcoin Network, have an adverse effect on the price of bitcoin and could have a negative impact on the Bitcoin Instruments in which certain of the Funds invest.
•   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.

Currently there are a several digital asset trading platforms that provide investors with forms of derivative products such as futures, so one could estimate and synthesize the discrete futures curve from the averages of various curves. MVIS research used BitMEX, OKCoin, CryptoFacilities, and BTCC as sources, to construct and approximate bitcoin futures curve based on non-U.S. bitcoin futures trading on these exchanges.
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]

CryptoFacilities, Coinpit, and BitMEX has a realtime profit realisation, while OKCoin and Deribit has weekly rebalancing scheduled for all contract lengths. It's important to note that on all of these exchanges, all the futures and forwards are non-deliverable and have expiration at various times. Despite this, OKCoin uses "delivery" as their term for expiration settlement of a contract, and "settlement" for the weekly rebalancing of the Pnl for higher length contracts. Since we are stuck with this unprofessional Chinese exchange being the dominant market player in futures, we have to focus on their use of the terminology, but BitMEX and CryptoFacilities have very impressive and professional setups that use well documented procedures. Always read the documentation of any exchange you're using and the contract specifications of the individual product you're using.

There are two USA regulated Bitcoin futures exchanges in operation. The CME’s contract unit is five Bitcoins whereas the Cboe’s contract unit is one—that’s the biggest difference between these futures. The upfront money to buy or sell short a CME contract will be about five times higher than the Cboe contract. Larger investors won’t care but this will be an issue for smaller investors. Another difference is the spot/settlement process that the exchanges use. In the case of Cboe futures, the contracts will be settled to a 4 pm ET Gemini exchange auction price on the day of expiration, for the CME futures the settlement price is a complex calculation using an hour of volume weighted data from multiple exchanges (currently Bitstamp, itBit, Kraken, and GDAX). With the CME’s approach, it will be harder to manipulate the settlement price but it doesn’t give arbitrageurs a physical mechanism to trade their positions—possibly an issue.
