The Trust and the fund have obtained an exemptive order from the SEC allowing a registered investment company to invest in the Fund’s shares beyond the limits of Section 12(d)(1) subject to certain conditions, including that a registered investment company enters into a Participation Agreement with the Trust regarding the terms of the investment. Any investment company considering purchasing shares of the Fund in amounts that would cause it to exceed the restrictions of Section 12(d)(1) should contact the Trust.

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.

Crypto derivatives were naturally discovered as an interesting addition to cryptocurrency exchanges first – probably as individual contracts between interested investors on these exchanges. Nowadays, there are already a couple of exchanges that offer crypto derivatives trading as a standard feature: BitMEX is the current market leader, according to The Merkle News; others are OKCoin, Crypto Facilities, Coinpit, and Deribit, as well as LedgerX (the first regulated cryptocurrency exchange in the US).
Mathematically, to regain a 50% loss you need the price to rise 100% (double) so don’t let yourself get there. Psychologically, you force yourself to trade to make up for the losses, and under pressure, you won’t make the best decisions. Cut losses early and re-evaluate your reasons for the trade, go back in later on, at a lower price if needed. Don’t take profits early, wait for a drop – this is a good enough place to close the trade
  •   Lack of liquid markets, and possible manipulation of blockchain-based assets. Digital assets that are represented and trade on a blockchain may not necessarily benefit from viable trading markets. Stock exchanges have listing requirements and vet issuers, and perhaps users. These conditions may not necessarily be replicated on a blockchain, depending on the platform’s controls and other policies. The more lenient a blockchain is about vetting issuers of digital assets or users that transact on the platform, the higher the potential risk for fraud or the manipulation of digital assets. These factors may decrease liquidity or volume, or increase volatility of digital securities or other assets trading on a blockchain.
In general, for purposes of the 90% gross income requirement described in subparagraph (a) above, income derived from a partnership will be treated as Qualifying Income only to the extent such income is attributable to items of income of the partnership which would be Qualifying Income if realized directly by the RIC. However, 100% of the net income of a RIC derived from an interest in a “qualified publicly traded partnership” (a partnership (x) the interests in which are traded on an established securities market or readily tradable on a secondary market or the substantial equivalent thereof, and (y) that derives less than 90% of its income from the
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 Trustees, their birth date, term of office and length of time served, principal business occupations during the past five years and the number of portfolios in the Fund Complex overseen and other directorships, if any, held by each Trustee, are shown below. Unless noted otherwise, the addresses of each Trustee is: c/o ProShares Trust, 7501 Wisconsin Avenue, Suite 1000E, Bethesda, MD 20814.
Each Fund may enter into swap agreements to invest in a market without owning or taking physical custody of securities. On a typical long swap, the counterparty will generally agree to pay the Fund the amount, if any, by which the notional amount of the swap agreement would have increased in value had it been invested in the particular underlying assets (e.g., an ETF, or securities comprising a benchmark index), plus the dividends or interest that would have been received on those assets. The Fund will agree to pay to the counterparty a floating rate of interest on the notional amount of the swap agreement plus the amount, if any, by which the notional amount would have decreased in value had it been invested in such assets plus, in certain instances, commissions or trading spreads on the notional amount. Therefore, the return to the Fund on such swap agreements should be the gain or loss on the notional amount plus dividends or interest on the assets less the interest paid by the Fund on the notional amount. As a trading technique, the Advisor may substitute physical securities with a swap agreement having investment characteristics substantially similar to the underlying securities. Some Funds may also enter into swap agreements that provide the opposite return of their benchmark or a security. Their operations are similar to that of the swaps disclosed above except that the counterparty pays interest to each Fund on the notional amount outstanding and that dividends or interest on the underlying instruments reduce the value of the swap, plus, in certain instances, each Fund will agree to pay to the counterparty commissions or trading spreads on the notional amount. These amounts are often netted with any unrealized gain or loss to determine the value of the swap.
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.
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.
When you display any broker’s profile page on the CME list above, you will see on the right hand side this broker’s specialties (a list of industries and/or financial products). As of this articles publication (Nov. 24, 2017), only one broker has added Bitcoin to his list of specialties: Level Trading Field LLC. However, this does not mean that the other brokers won’t handle Bitcoin futures. We expect that more of them will adopt this specialty as soon as Bitcoin futures are on the market.
reduce the amount of the Fund’s borrowings to the extent necessary to meet this 300% coverage requirement. Maintenance of this percentage limitation may result in the sale of portfolio securities at a time when investment considerations would not favor such sale. In addition to the foregoing, the Funds are authorized to borrow money as a temporary measure for extraordinary or emergency purposes in amounts not in excess of 5% of the value of each Fund’s total assets. This borrowing is not subject to the foregoing 300% asset coverage requirement. The Funds are authorized to pledge portfolio securities as ProShare Advisors deems appropriate in connection with any borrowings.
This may sound like an unfair system to those who are used to trading with confidence that their profits are settled in full, but it's a compromise that has been made in order to offer the high leverage. If you want to guarantee that your profits are not reduced by any socialised loss, then use CryptoFacilities or Coinpit. They use a "termination" procedure in the event of a margin call not being filled. This simply terminates the contract and sends the portfolio value of the losing counterparty to the winning counterparty. It's worth noting that the system has been incredibly robust, with very minimal socialised losses being triggered on OKCoin and none on BitMEX as of November 2015.

Update 1st October 2018: The cryptocurrency market has been volatile as ever over the last 6 months. Unless you are a skilled trader, it is harder to make money in a bear market than in a bull market – and we have been in a bear market for some time now. Personally, I have stopped trading and I am now focussing on growing my portfolio passively using a cryptocurrency trading bot – you can find out more about this here.  If you are new to crypto, read on!
The Fund will issue and redeem shares only to Authorized Participants (typically, broker-dealers) in exchange for the deposit or delivery of a basket of assets (securities and/or cash) in large blocks, known as Creation Units, each of which is comprised of [                ] shares. Retail investors may only purchase and sell Fund shares on a national securities exchange through a broker-dealer. Because the Fund’s shares trade at market prices rather than NAV, shares may trade at a price greater than NAV (a premium) or less than NAV (a discount).

Each Fund may buy and write (sell) options for the purpose of realizing its investment objective. By buying a call option, a Fund has the right, in return for a premium paid during the term of the option, to buy the asset underlying the option at the exercise price. By writing a call option a Fund becomes obligated during the term of the option to sell the asset underlying the option at the exercise price if the option is exercised. By buying a put option, a Fund has the right, in return for a premium paid during the term of the option, to sell the asset underlying the option at the exercise price. By writing a put option, a Fund becomes obligated during the term of
A Fund may invest in one or more exchange-traded funds that invest in commodities or options, futures, or forwards with respect to commodities, and are treated as QPTPs for federal income tax purposes. As noted above, a Fund is limited to investing no more than 25% of the value of its total assets in the securities of one or more QPTPs. Although income from QPTPs is generally qualifying income, if an ETF intending to qualify as a QPTP fails to so qualify and is treated as a partnership for U.S. federal income tax purposes, a portion of its income may not be qualifying income. It is also possible that an ETF intending to qualify as a QPTP will be treated as a corporation for federal income tax purposes. In such a case, it will be potentially liable for an entity-level corporate income tax, which will adversely affect the return thereon. There can be no guarantee that any ETF will be successful in qualifying as a QPTP. In addition, there is little regulatory guidance concerning the application of the rules governing qualification as a QPTP, and it is possible that future guidance may adversely affect the qualification of ETFs as QPTPs. A Fund’s ability to pursue an investment strategy that involves investments in QPTPs may be limited by that Fund’s intention to qualify as a RIC, and may bear adversely on that Fund’s ability to so qualify.
Investment in mortgage-backed securities poses several risks, including among others, prepayment, market and credit risk. Prepayment risk reflects the risk that borrowers may prepay their mortgages faster than expected, thereby affecting the investment’s average life and perhaps its yield. Whether or not a mortgage loan is prepaid is almost entirely controlled by the borrower. Borrowers are most likely to exercise prepayment options at the time when it is least advantageous to investors, generally prepaying mortgages as interest rates fall, and slowing payments as interest rates rise. Besides the effect of prevailing interest rates, the rate of prepayment and refinancing of mortgages may also be affected by appreciation in home values, ease of the refinancing process and local economic conditions. Market risk reflects the risk that the price of a security may fluctuate over time. The price of mortgage-backed securities may be particularly sensitive to prevailing interest rates, the length of time the security is expected to be outstanding, and the liquidity of the issue. In a period of unstable interest rates, there may be decreased demand for certain types of mortgage-backed securities, and each Fund invested in such securities wishing to sell them may find it difficult to find a buyer, which may in turn decrease the price at which they may be sold. Credit risk reflects the risk that a Fund may not receive all or part of its principal because the issuer or credit enhancer has defaulted on its obligations. Obligations issued by U.S. government-related entities are guaranteed as to the payment of principal and interest, but are not backed by the full faith and credit of the U.S. government. The performance of private label mortgage-backed securities, issued by private institutions, is based on the financial health of those institutions. With respect to GNMA certificates, although GNMA guarantees timely payment even if homeowners delay or default, tracking the “pass-through” payments may, at times, be difficult.

Qualifying Income described in clause (i) of subparagraph (a) above) will be treated as Qualifying Income. In general, such entities will be treated as partnerships for federal income tax purposes because they meet the passive income requirement under Code section 7704(c)(2). In addition, although in general the passive loss rules of the Code do not apply to RICs, such rules do apply to a RIC with respect to items attributable to an interest in a qualified publicly traded partnership. Moreover, the amounts derived from investments in foreign currency will be treated as Qualifying Income for purposes of subparagraph (a) above. There is a remote possibility that the Internal Revenue Service (“IRS”) could issue guidance contrary to such treatment with respect to foreign currency gains that are not directly related to a RIC’s principal business of investing in stocks or securities (or options or futures with respect to stocks or securities), which could affect a Fund’s ability to meet the 90% gross income test and adversely affect the manner in which that Fund is managed.

Each Fund may invest in master limited partnerships (“MLPs”), which are commonly treated as partnerships for U.S. federal income tax purposes and publicly traded on national securities exchanges. Such MLPs are limited by the Internal Revenue Code to apply to enterprises that engage in certain businesses, mostly pertaining to the use of natural resources, such as natural gas extraction and transportation. Some real estate enterprises may also qualify as MLPs.

  pursuit of its investment strategies will potentially be limited by the Fund’s intention to qualify for such treatment and could adversely affect the Fund’s ability to so qualify. The Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, the Fund were to fail to qualify for the special tax treatment accorded a RIC and its shareholders, and were ineligible to or were not to cure such failure, the Fund would be taxed in the same manner as an ordinary corporation subject to U.S. federal income tax on all its income at the fund level. The resulting taxes could substantially reduce the Fund’s net assets and the amount of income available for distribution. In addition, in order to requalify for taxation as a RIC, the Fund could be required to recognize unrealized gains, pay substantial taxes and interest, and make certain distributions.

If you are doing any active trading, set stop losses. For any coins not in your medium or long-term holds, always set stop losses. This is important for several reasons — the most obvious is mitigating your losses. But more importantly, you force yourself to decide on a point of acceptable loss, and because you now have a reference point, you are able to measure your effectiveness to keep or adjust for future trades. Sometimes, during a market dip, altcoins can plummet, and stop losses can lead to profitability by automatically selling for fiat that you can use to re-enter at lower prices.

Some Funds focus their investments in particular foreign geographical regions or countries. In addition to the risks of investing in foreign securities discussed above, the investments of such Funds may be exposed to special risks that are specific to the country or region in which the investments are focused. Furthermore, Funds with such a focus may be subject to additional risks associated with events in nearby countries or regions or those of a country’s principal trading partners. Additionally, some Funds have an investment focus in a foreign country or region that is an emerging market and, therefore, are subject to heightened risks relative to Funds that focus their investments in more developed countries or regions.
So be aware of the premium or discount that is on longer dated contracts, this can allow you some arbitrage opportunities if you are patient and have the coins to apply to it. In general, we recommend that you trade any contract that has good liquidity and high volume. This is the most important characteristic of ANY product for a trader. If you can't get in and out reliably, and have a price that reasonably follows the spot market behavior, then it's not worth trading.

This post-effective amendment relates only to ProShares Bitcoin Futures Strategy ETF, ProShares Short Bitcoin Futures Strategy ETF, ProShares Bitcoin Futures/Equity Strategy ETF and ProShares Bitcoin/Blockchain Strategy ETF, each a new series of ProShares Trust. No information relating to any other series or class of series of ProShares Trust is amended or superseded hereby.
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.
Disctric0x is a network of decentralized communities and marketplaces, and where each ‘district’ is a decentralized entity on the district0x Network. In other words, District0x allows anyone to create a network of communities (or organizations) with a focus on governance, cooperation and decision making being decentralized. District0x is an open-source software project, and as such, it does not seek to gain profit, but rather focuses all of its attention towards building software that enables development and governance of marketplaces that are powered by the community.
Distributions are taxable whether shareholders receive them in cash or reinvest them in additional shares. Distributions are also taxable to shareholders even if they are paid from income or gains earned by a Fund before a shareholder’s investment (and thus were included in the price the shareholder paid for the Fund shares). Investors should be careful to consider the tax implications of buying shares of a Fund just prior to a distribution. The price of shares purchased at this time will include the amount of the forthcoming distribution, but the distribution will generally be taxable.
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.
On May 7, 2014, the SEC published an investor alert that highlighted fraud and other concerns relating to certain investment opportunities denominated in bitcoin and fraudulent and unregistered investment schemes targeted at participants in online bitcoin forums. On July 25, 2017, the SEC issued a Report of Investigation or Report which concluded that digital assets or tokens issued for the purpose of raising funds may be securities within the meaning of the federal securities laws. The Report emphasized that whether a digital asset is a security is based on the particular facts and circumstances, including the economic realities of the transactions. This was reiterated in a December 11, 2017 Public Statement emphasizing the risks of investing in digital assets such as bitcoin and noting the possibility that bitcoin and other digital assets may be deemed to be securities. The SEC continues to take action against persons or entities misusing bitcoin in connection with fraudulent schemes (i.e., Ponzi scheme), inaccurate and inadequate publicly disseminated information, and the offering of unregistered securities.
Bitcoin (BTC) has been engaged in a predictable up and down pattern where it absolutely crashes at the beginning of any year and then sky-rockets as the year nears its end. Bitcoin held steady at around $19,000 in December 2017, and then sure enough – crashed big time to around $6,000 at the beginning of 2018. At the time of writing, March 8th 2018, the price of Bitcoin is relatively stable between $10,000 and $12,000. In my opinion, the price will run again soon.
“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.”
Each Fund may be required to withhold federal income tax (“backup withholding”) from dividends and capital gains distributions paid to shareholders. Federal tax will be withheld if (1) the shareholder fails to furnish the Fund with the shareholder’s correct taxpayer identification number or social security number, (2) the IRS notifies the shareholder or the Fund that the shareholder has failed to report properly certain interest and dividend income to the IRS and to respond to notices to that effect, or (3) when required to do so, the shareholder fails to certify to the Fund that he or she is not subject to backup withholding. The backup withholding rate is 28%. Any amounts withheld under the backup withholding rules may be credited against the shareholder’s federal income tax liability.

These days, all of the BTC/USD contracts trading at active futures markets are inverse, as mentioned in the beginning of this guide. The only differences between the exchanges is how they trigger liquidations and the procedure for handling margin calls. They all use Bitcoin as the currency, of course, and you can use the table below for a basic feature comparison:

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]
When Bitconnect was exposed as a 100% scam and was shut down, the price dropped vertically to almost zero. But then, it bounced back up by something like 15-30 percent, and it kept going up for a couple of days. This is caused, in my opinion, by the fact that bots and cavemen technical analysts, who never follow the news, look at the chart and think “this is a great time to buy”.

Under certain circumstances, a Fund may recognize gain from a constructive sale of an “appreciated financial position” it holds if it enters into a short sale, forward contract or other transaction that substantially reduces the risk of loss with respect to the appreciated position. In that event, the Fund would be treated as if it had sold and immediately repurchased the property and would be taxed on any gain (but would not recognize any loss) from the constructive sale. The character of gain from a constructive sale would depend upon each Fund’s holding period in the property. Appropriate adjustments would be made in the amount of any gain or loss subsequently realized on the position to reflect the gain recognized on the constructive sale. Loss from a constructive sale would be recognized when the property was subsequently disposed of, and its character would depend on the Fund’s holding period and the application of various loss deferral provisions of the Code. Constructive sale treatment does not generally apply to a transaction if such transaction is closed on or before the end of the 30th day after the close of the Fund’s taxable year and the Fund holds the appreciated financial position throughout the 60-day period beginning with the day such transaction closed. The term “appreciated financial position” excludes any position that is “marked-to-market.”
"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."

!! WARNING !!! Note that on CryptoFacilities each contract is denominated by 1 BTC. So if you bought a fraction of BTC you can NOT perform a perfect hedge of the value. If you round the BTC you bought with start capital down, you will have slight overexposure LONG with the left-over BTC. If you round up and short an extra contract, you will have slight overexposure SHORT.
