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).

Total Return Swaps. Total return swaps are used either as substitutes for owning the physical securities that comprise a given market index or as a means of obtaining non-leveraged exposure in markets where securities are not available. “Total return” refers to the payment (or receipt) of an index’s total return, which is then exchanged for the receipt (or payment) of a floating interest rate. Total return swaps provide the Fund with the additional flexibility of gaining exposure to a market or sector index by using the most cost-effective vehicle available.

Banks may not provide banking services, or may cut off banking services, to businesses that provide bitcoin-related services or that accept bitcoin as payment, which could damage the public perception of bitcoin and the utility of bitcoin as a payment system and could decrease the price of bitcoin and the Bitcoin Instruments and adversely affect an investment in the Funds.
The Guidelines are maintained and implemented by ISS and are an extensive list of common proxy voting issues with recommended voting actions based on the overall goal of achieving maximum shareholder value and protection of shareholder interests. Generally, proxies are voted in accordance with the voting recommendations contained in the Guidelines. If necessary, the Advisor will be consulted by ISS on non-routine issues. Proxy issues identified in the Guidelines include but are not limited to:
Crypto Facilities and the CME Group  have been calculating and publishing the Bitcoin Reference Rate (BRR) since November 2016. Such an official rate is a prerequisite of options trading in the traditional markets. The BRR is calculated based on the rates from the biggest exchanges: Bitstamp, GDAX, itBit, and Kraken. More concretely, it is calculated based on all Bitcoin vs. USD trades on the participating exchanges between 3 and 4 p.m. London time. To calculate the BRR, the hour between 3 and 4 is divided into 12 intervals of 5 minutes. For each interval, the volume-weighted median of the Bitcoin price is calculated (statistically, the median, in contrast to the average, prevents single outliers from distorting the price). The BRR is then the average of these 12 median values. More details about the calculation of the BRR can be found in the BRR whitepaper.
This can serve two purposes; firstly, CFDs are a regulated financial product which means the brokers who offer them should be licensed by a regulatory authority. The brokers we review are all regulated by reputable financial regulatory bodies, offering varying degrees of protection for your money – from ensuring it is held in a segregated bank account to participation in compensation schemes should the broker become insolvent. There are, of course, criminal CFD brokers operating outside the law so you should do your homework before depositing!

Commodity Swaps. Commodity swaps are used either as substitutes for owning a specific physical commodities or as a means of obtaining non-leveraged exposure in markets where a specific commodity is not available. Commodity swaps provide the Fund with the additional flexibility of gaining exposure to commodities by using the most cost-effective vehicle available.
The Funds may make short sales “against the box,” i.e., when a security identical to or convertible or exchangeable into one owned by a Fund is borrowed and sold short. Whenever a Fund engages in short sales, it earmarks or segregates liquid securities or cash in an amount that, when combined with the amount of collateral deposited with the broker in connection with the short sale, equals the current market value of the security sold short. The earmarked or segregated assets are marked-to-market daily.
Cryptocurrency is based on knowledge sharing on a distributed platform. The entire transactional history is for everyone to see. One blockchain is one thread of transaction. One unit or one block stores many transactions. The size of the block is 1MB and generally stores around 1000 to 2000 transactions. The data entered cannot be altered, nor can it be removed, enabling a system of complete transparency and trust. The entire money flow for the working model is beyond the traditional practices of controlling tax rates, credit usage, and money supply in the market.

Market Spotlight – Bitcoin - A cryptocurrency is a digital asset designed to work as a medium of exchange using cryptography to secure transactions, control creation, and verify transactions. The first such cryptocurrency, Bitcoin, was introduced in 2009. In 2017, the exchanges launched a Bitcoin futures contract. The CBOE contract launched on Sunday, December 10, while the CME contract launched on Monday, December 18.
An Authorized Participant who exchanges securities for Creation Units generally will recognize a gain or a loss. The gain or loss will be equal to the difference between the market value of the Creation Units at the time and the sum of the exchanger’s aggregate basis in the securities surrendered plus the amount of cash paid for such Creation Units. An Authorized Participant who redeems Creation Units will generally recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the sum of the aggregate market value of any securities received plus the amount of any cash received for such Creation Units. The IRS, however, may assert that a loss realized upon an exchange of securities for Creation Units cannot be deducted currently under the rules governing “wash sales,” or on the basis that there has been no significant change in economic position. Persons purchasing or redeeming Creation Units should consult their own tax advisors with respect to the tax treatment of any creation or redemption transaction.
reporting systems. As of October 2016, the Advisor has separate arrangements to make payments, other than for the educational programs and marketing activities described above, to Charles Schwab & Co., Inc. and Raymond James Financial Services, Inc. (the “Firms”). Pursuant to the arrangements with the Firms, the Firms agreed to promote certain ProShares ETFs to each Firm’s customers and not to charge certain of their customers any commissions when those customers purchase or sell shares of certain ProShares ETFs. These payments, which may be significant, are paid by the Advisor from its own resources and not from the assets of the Funds. A discussion regarding the basis for the Board of Trustees approving the Advisory Agreement of the Trust will be (or is) available in the Trust’s Annual and/or Semi-Annual Report to shareholders. The Investment Advisory fees paid, as well as any amounts reimbursed pursuant to the Expense Limitation Agreement, for the fiscal years ended May 31, 2015, May 31, 2016 and May 31, 2017 for each Fund that was operational as of each date are set forth below. Because each of the New Funds was not operational at the end of the Trust’s last fiscal year, information on investment advisory fees paid by the Fund is not included in this SAI.

Look, you and I are sophisticated, and we get that "bitcoin's price increase is deflationary and makes it a bad currency" is not a good argument against bitcoin, because "bitcoin is a bad currency" is not a good argument against bitcoin. (People keep making it though.) Bitcoin's value proposition -- much like that of gold -- is that it is an uncorrelated store of value, not that it is useful for buying a sandwich. But at the same time you have to watch out for business models that are based on the casual assumption that bitcoin works just like a currency. "Cryptocurrency-financed warehouse lending" has the word "cryptocurrency" in it, so it's worth billions of dollars, but I'm not sure it works as a business model.
The introduction of futures didn't lead to a wave of hedge-fund money shorting bitcoin. It led to retail and institutional money going long bitcoin. We talked last week about the spread between Cboe's bitcoin futures price and the actual price of bitcoin, which was wider than $1,000 for a while. The spread has tightened considerably -- as of 8:15 a.m. today, the CME futures traded at $18,585, Cboe futures at $18,670, and spot bitcoin at about $18,245, for a spread of about 2 percent -- but it still exists. Why would you pay more for a synthetic bitcoin in a month than you would for an actual bitcoin today? The answer, presumably, is that the synthetic bitcoin is more valuable to you: You want bitcoin exposure, but you'd prefer to get it through a standardized contract on a regulated exchange that settles in dollars. 

Under a Rule 12b-1 Distribution Plan (the “Plan”) adopted by the Board, each Fund may pay its distributor and financial intermediaries, such as broker-dealers and investment advisors, up to 0.25% on an annualized basis of the average daily net assets of a Fund as reimbursement or compensation for distribution related activities with respect to the Funds. Because these fees are paid out of each Fund’s assets on an on-going basis, over time these fees will increase the cost of your investment and may cost you more than paying other types of sales charges. For the prior fiscal year, no payments were made by the fund under the Plan.
It will not, though: Everyone is exhausted, so P&G will just add Peltz to its board. This makes sense. The election is for all practical purposes a tie; the difference in votes appears to be well within the margin for measurement error. I think in that scenario a tie has to go to the activist: If 49.98 percent of your shareholders think something is going wrong, you might as well do something to appease them. 
Created by Charlie Lee, a former Google engineer, Litecoin is an open-source payment network that operates on a global scale. It is not controlled by any centralized power, and it uses the “scrypt” as proof-of-work. It is similar to Bitcoin but has the advantage of offering a faster rate of generation and therefore faster transactions. This is one of the main reasons why its enthusiasts continue to invest or hold onto the coin even after finding out that its founder sold his stack.
Bitcoin is maintained on the decentralized, open source protocol of the peer-to-peer bitcoin computer network (the “Bitcoin Network”). No single entity owns or operates the Bitcoin Network. The infrastructure of the Bitcoin Network is collectively maintained by a decentralized user base. The Bitcoin Network is accessed through software, and software governs bitcoin’s creation, movement, and ownership. The value of bitcoin is determined in great part by the supply of (which is limited), and demand for, bitcoin in the global exchange markets for the trading of bitcoin (individually, “Bitcoin Exchanges” and collectively, the “Bitcoin Exchange Market”), market expectations for the adoption of bitcoin and the volume of private user-to-user transactions.
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.
Forex trading is exciting yet involves a certain level of risk.

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.
The fund performance for a Geared ProShares Fund can be estimated given any set of assumptions for the factors described above. The tables on the next five pages illustrate the impact of two factors, benchmark volatility and benchmark performance, on a Geared Fund. Benchmark volatility is a statistical measure of the magnitude of fluctuations in the returns of a benchmark and is calculated as the standard deviation of the natural logarithm of one plus the benchmark return (calculated daily), multiplied by the square root of the number of trading days per year (assumed to be 252). The tables show estimated Fund returns for a number of combinations of benchmark performance and benchmark volatility over a one-year period. Assumptions used in the tables include: (a) no dividends paid with respect to securities included in the underlying benchmark; (b) no Fund expenses; and (c) borrowing/lending rates (to obtain leverage or inverse exposure) of zero percent. If Fund expenses and/or actual borrowing lending rates were reflected, the Fund’s performance would be different than shown.
BitMEX also has a weekly rebalancing for all their contracts, but currently their most popular product is the Daily 100x maximum leverage contract. This settles daily, but otherwise the rest of the contracts are handled on Friday, a little bit after OKCoin's 8:00AM UTC. See this website to get a countdown to the settlements on the different exchanges. The policies of exchanges are changing often so this information may be outdated by the time you read it (though we will try to keep it as up to date as possible).

CCC/CC/C – Very highly speculative credit quality. In danger of defaulting on financial obligations. There is little difference between these three categories, although CC and C ratings are normally applied to obligations that are seen as highly likely to default, or subordinated to obligations rated in the CCC to B range. Obligations in respect of which default has not technically taken place but is considered inevitable may be rated in the C category.
Bitcoin has a very limited history of operations and there is no established performance record for the price of Bitcoin on the Bitcoin Exchange Market that can provide an adequate basis for evaluating an investment in bitcoin or Bitcoin Instruments such as Bitcoin Derivatives, ETNs and Bitcoin Securities. Although past performance is not necessarily indicative of future results, if bitcoin had an established history, such history might (or might not) provide investors with more information on which to evaluate an investment in the Funds.
So far, these derivatives market have only been a niche occupied by crypto enthusiasts. That is until one of the newcomers, Crypto Facilities, and an incumbent in the derivatives market have joined forces: Crypto Facilities and the CME Group. The CME Group (controlling, for example, the Chicago Mercantile Exchange that has been around for more than a century) is a large-scale business that is officially regulated and audited by the US financial authorities. It settles its contracts in fiat money rather than cryptocurrency, thus enabling non-crypto experts to speculate on Bitcoin.
