Exchanges simply take a fee to facilitate the orderbook where its clients (the counterparties) create and trade futures contract with each other. They also have to manage the system's risk so that traders don't get overleveraged or manipulate the market. Since counterparties are only putting margin down that is a % of the contract value, the exchange also has to handle liquidation procedures in case the value of the margin is exceeded by the loss on the notional market value of the contract. For instance, BitMEX offers 100x leverage, so if you want to enter a $10,000 position you need to put down $100 worth of bitcoin. If the price moves just 0.5% against your favor, BitMEX will take over your position and execute it into the market, so that the person on the other side of the contract can have someone else who pays for the profit. In the event that the liquidation doesn't get passed off to another trader, an Auto-Deleveraging/Termination can occur, or Socialize Loss in the contract builds (we will discuss these issues in more detail later).

It is important to note, however, that leverage means that your potential losses may also be much higher. If pork belly prices fall, call options lose value in a much higher proportion than the pork bellies themselves. In the above example, if the price of pork bellies falls from 1,000 to 900 USD (by 10%), the price of call options may fall from 10.5 USD to almost zero, resulting in a near-total loss of your funds instead of a small loss of just 10%.

Certain Funds expect to invest in exchange-traded funds, including exchange-traded funds registered under the 1940 Act (“Underlying ETFs”). Some such Underlying ETFs will be treated as regulated investment companies for federal income tax purposes (each such Underlying ETF, an “Underlying RIC”). In such cases, a Fund’s income and gains will normally consist, in whole or part, of dividends and other distributions from the Underlying RICs and gains and losses on the disposition of shares of the Underlying RICs. The amount of income and capital gains realized by a Fund and in turn a Fund’s shareholders in respect of the Fund’s investments in Underlying RICs may be greater than such amounts would have been had the Fund invested directly in the investments held by the Underlying RICs, rather than in the shares of the Underlying RICs. Similarly, the character of such income and gains (e.g., long-term capital gain, eligibility for the dividends-received deduction, etc.) will not necessarily be the same as it would have been had the Fund invested directly in the investments held by the Underlying RICs.
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.

Localbitcoins is the portal that exchanges trades between person to person where you interact with the seller directly. On this platform, people from different countries can exchange their local currency to bitcoins. The site is suggested for casual traders seeking more privacy. The site uses an escrow system and the transfer of bitcoin is made after funds are received in the sellers account. Registering, buying and selling is completely free on localbitcoins while local bitcoin users who create advertisements charges 1% fee for every completed trade.

Important agents interacting with those prices are operating in one of three roles: individual speculator, market maker, or arbitrageur. A key role is market maker—a firm that has agreed to simultaneously act as both a buyer and seller for a specific security. When companies sign up for this role they agree to keep the bid/ask prices relatively close to each other—for example even if they aren’t keen on selling Bitcoins at the moment they can’t just set the ask price to an outrageous level. The agreed-upon maximum bid/ask ranges might be tied to market conditions (e.g., wider when deemed a “fast market”) and might allow time-outs but in general, the market maker agrees to act as a buffer between supply and demand.
On 21 November 2017, the Tether cryptocurrency announced they were hacked, losing $31 million in USDT from their primary wallet.[89] The company has 'tagged' the stolen currency, hoping to 'lock' them in the hacker's wallet (making them unspendable). Tether indicates that it is building a new core for its primary wallet in response to the attack in order to prevent the stolen coins from being used.
Words of caution are appropriate when talking about going short and using leverage. These strategies are incredibly effective because they allow investors to not only profit from a general upward trend in bitcoin but to profit from the fluctuations in the market. At first, it is hard to think of a more perfect asset than bitcoin for such purposes. The upward trends have been fast and extreme, yet fluctuations are very common and tend to be substantial.

Moody’s ratings for state and municipal notes and other short-term loans are designated Moody’s Investment Grade (MIG) and for variable rate demand obligations are designated Variable Moody’s Investment Grade (VMIG). This distinction recognizes the differences between short-term credit risk and long-term risk. Loans bearing the designation MIG-1/VMIG-1 are of the best quality, enjoying strong protection from established cash flows of funds for their servicing or from established and broad-based access to the market for refinancing, or both. Loans bearing/with the designation MIG-2/VMIG-2 are of high quality, with ample margins of protection, although not as large as the preceding group.
The Board of Trustees of the Trust reserves the right to declare a split or a consolidation in the number of Shares outstanding of any Fund, and may make a corresponding change in the number of Shares constituting a Creation Unit, in the event that the per Share price in the secondary market rises (or declines) to an amount that falls outside the range deemed desirable by the Board.

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.
One traditional attraction of trading futures is the ability to use relatively small amounts of money to potentially achieve outsized returns. In many futures markets the margin, the amount of money that your broker requires up-front before executing the trade can be quite small compared to the ultimate value of the contract. For example, as of 22-Dec-2017, each E-mini S&P 500 contract was worth $134K ($50*S&P 500 index value)—this “list price” of the contract is called its notional value.  The CME only requires you to maintain a minimum margin of $4.5K (3.4% of notional) to control this contract (brokers often require additional margin). Margin requirements this low are only possible because the volatility of the S&P 500 is well understood and your margin account balance is adjusted at the end of every trading day to account for the winnings or losses of the day. If your account balance falls below the margin minimum of $4.5K you’ll need to quickly add money to your account or your position will be summarily closed out by your broker. On the plus side, if you’ve predicted the S&P’s direction correctly your profits will be that same as if you completely owned the underlying stocks in the index. A +1% daily move in the S&P500 would yield $1340 in profit even though you only have $4500 invested— a 29% return—this multiplier effect is called leverage.
The tables below shows performance examples of an Ultra and UltraShort ProShares Fund that have investment objective to correspond to two times (2x) and two times the inverse (-2x) of, respectively, the daily performance of an index. In the charts below, areas shaded lighter represent those scenarios where a Fund will return the same or outperform (i.e., return more than) the index performance times the stated multiple in the Fund’s investment objective; conversely areas shaded darker represent those scenarios where the Fund will underperform (i.e., return less than) the index performance times the stated multiple in the Fund’s investment objective.

Certain of a Fund’s investments in derivative instruments and foreign currency-denominated instruments, and any of a Fund’s transactions in foreign currencies and hedging activities, are likely to produce a difference between its book income and its taxable income. If such a difference arises, and a Fund’s book income is less than its taxable income, the Fund could be required to make distributions exceeding book income to qualify as a RIC that is accorded special tax treatment. In the alternative, if a Fund’s book income exceeds its taxable income (including realized capital gains), the distribution (if any) of such excess generally will be treated as (i) a dividend to the extent of the Fund’s remaining earnings and profits (including earnings and profits arising from tax-exempt income), (ii) thereafter, as a return of capital to the extent of the recipient’s basis in its shares, and (iii) thereafter as gain from the sale or exchange of a capital asset.

The Trust’s website has information about the premiums and discounts for each Fund. Premiums or discounts are the differences between the NAV and market price of a Fund on a given day, generally at the time NAV is calculated. A premium is the amount that a Fund is trading above the NAV. A discount is the amount that the Fund is trading below the NAV.
In order to provide current Share pricing information, an Exchange disseminates an updated Indicative Optimized Portfolio Value (“IOPV”) for each Fund. The Trust is not involved in or responsible for any aspect of the calculation or dissemination of the IOPVs and makes no warranty as to the accuracy of the IOPVs. IOPVs are expected to be disseminated on a per Fund basis every 15 seconds during regular trading hours of an Exchange.
To the extent that an Underlying RIC realizes net losses on its investments for a given taxable year, a Fund that invests in the Underlying RIC will not be able to benefit from those losses until (i) the Underlying RIC realizes gains that it can reduce by those losses, or (ii) the Fund recognizes its share of those losses when it disposes of shares in the Underlying RIC. Moreover, when a Fund makes such a disposition, any loss it recognizes will be a capital loss. A Fund will not be able to offset any capital losses from its dispositions of shares of the Underlying RIC against its ordinary income (including distributions deriving from net short-term capital gains realized by the Underlying RIC). In addition, a portion of such capital loss may be long-term, which will first offset the Fund’s capital gains, increasing the likelihood that the Fund’s short-term capital gains will be distributed to shareholders as ordinary income.
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.
Having said that, bitcoin price action remains fraught with wild and inexplicable gaps, like a $400 drop and rise in an hour in the late hours of July 30, according to Bloomberg.  This particular trade, and unwind seems to have affected bitcoin pricing globally and likely impacted trading of the U.S. listed contracts as well.  Volumes and open interest seemed to have increased around the time of this large trade unwind.  It could be a coincidence, though I suspect that some smart traders, aware of the situation, put short trades on in these future contracts to take advantage of the forced unwind.
The Registrant (also, the “Trust”) is organized as a Delaware business trust is operated pursuant to an Amended and Restated Declaration of Trust, dated December 13, 2010 (the “Declaration of Trust”), that permits the Registrant to indemnify every person who is, or has been, a Trustee, officer, employee or agent of the Trust, including persons who serve at the request of the Trust as directors, trustees, officers, employees or agents of another organization in which the Trust has an interest as a shareholder, creditor or otherwise (hereinafter referred to as a “Covered Person”), shall be indemnified by the Trust to the fullest extent permitted by law against liability and against all expenses reasonably incurred or paid by him in connection with any claim, action, suit or proceeding in which he becomes involved as a party or otherwise by virtue of his being or having been such a Trustee, director, officer, employee or agent and against amounts paid or incurred by him in settlement thereof. This indemnification is subject to the following conditions:
Unsponsored ADR programs are organized independently and without the cooperation of the issuer of the underlying securities. As a result, available information concerning the issuers may not be as current for unsponsored ADRs, and the price of unsponsored depositary receipts may be more volatile than if such instruments were sponsored by the issuer and/or there may be no correlation between available information and the market value.
Bitcoin is pseudonymous rather than anonymous in that the cryptocurrency within a wallet is not tied to people, but rather to one or more specific keys (or "addresses").[53] Thereby, bitcoin owners are not identifiable, but all transactions are publicly available in the blockchain.[53] Still, cryptocurrency exchanges are often required by law to collect the personal information of their users.[53]
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.
Mortgage-backed securities issued by private issuers, whether or not such obligations are subject to guarantees by the private issuer, may entail greater risk than obligations directly or indirectly guaranteed by the U.S. government. The average life of a mortgage-backed security is likely to be substantially shorter than the original maturity of the mortgage pools underlying the securities. Prepayments of principal by mortgagors and mortgage foreclosures will usually result in the return of the greater part of principal invested far in advance of the maturity of the mortgages in the pool.
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.

In cryptocurrency networks, mining is a validation of transactions. For this effort, successful miners obtain new cryptocurrency as a reward. The reward decreases transaction fees by creating a complementary incentive to contribute to the processing power of the network. The rate of generating hashes, which validate any transaction, has been increased by the use of specialized machines such as FPGAs and ASICs running complex hashing algorithms like SHA-256 and Scrypt.[38] This arms race for cheaper-yet-efficient machines has been on since the day the first cryptocurrency, bitcoin, was introduced in 2009.[38] With more people venturing into the world of virtual currency, generating hashes for this validation has become far more complex over the years, with miners having to invest large sums of money on employing multiple high performance ASICs. Thus the value of the currency obtained for finding a hash often does not justify the amount of money spent on setting up the machines, the cooling facilities to overcome the enormous amount of heat they produce, and the electricity required to run them.[38][39]
As of September 16, 2017, the Trustees and officers of the Trust, as a group, owned outstanding shares that entitled them to give voting instructions with respect to less than one percent of the shares of any series of the Trust; except that Mr. Michael L. Sapir owned more than 25% of the outstanding shares of ProShares S&P 500 Ex-Financials ETF and ProShares S&P 500 Ex-Health Care ETF.

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.
