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.
Unlike many commodity futures, Bitcoin futures are cash settled rather than physically settled.  Cash settlement is a relatively new development in futures trading, first introduced in 1981 for Eurodollar futures, that addresses the problem of how to settle futures contracts on things that are difficult/impossible to deliver physicially—things like interest rates, large stock indexes (e.g., S&P 500), and volatility indexes (Cboe’s VIX).  Futures physical settlement involves actual shipment/change of ownership of the underlying product to the contract holder but in practice, it’s rarely used (~2% of the time).  Instead, most organizations that are using futures to hedge prices of future production/usage will make separate arrangements with suppliers/customers for physical delivery and just use the futures to protect against contrary price changes.  In practice, the final settlement price of the contract can be used to provide the desired price protection regardless of whether the futures contract specifies physically delivery or cash-settlement.
Portfolio holdings information may not be provided prior to its public availability (“Non-Standard Disclosure”) in other circumstances except where appropriate confidentiality arrangements limiting the use of such information are in effect. Non-Standard Disclosure may be authorized by the Trust’s CCO or, in his absence, any other authorized officer of the Trust if he determines that such disclosure is in the best interests of the Fund’s shareholders, no conflict exists between the interests of the Fund’s shareholders and those of the Advisor or Distributor and such disclosure serves a legitimate business purpose, and measures discussed in the previous paragraph regarding confidentiality are satisfied. The lag time between the date of the information and the date on which the information is disclosed shall be determined by the officer authorizing the disclosure. The CCO is responsible for ensuring that portfolio holdings disclosures are made in accordance with this Policy.
•   Credit Risk — The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is, or is perceived to be, unable or unwilling to pay interest, repay principal on time, or defaults. The value of an investment in the Fund may change quickly and without warning as a result of issuer defaults or actual or perceived changes in the credit ratings of the Fund’s portfolio investments or to an issuer’s financial strength.
The SEC staff also has acknowledged that, while a board of trustees retains ultimate responsibility, trustees may delegate this function to an investment adviser. The Board of Trustees has delegated this responsibility for determining the liquidity of Rule 144A restricted securities that may be invested in by a Fund to the Advisor. It is not possible to predict with assurance exactly how the market for Rule 144A restricted securities or any other security will develop. A security that when purchased enjoyed a fair degree of marketability may subsequently become illiquid and, accordingly, a security that was deemed to be liquid at the time of acquisition may subsequently become illiquid. In such an event, appropriate remedies will be considered in order to minimize the effect on the Fund’s liquidity.
Interest Rate Swaps. Interest rate swaps, in their most basic form, involve the exchange by a Fund with another party of their respective commitments to pay or receive interest. For example, a Fund might exchange its right to receive certain floating rate payments in exchange for another party’s right to receive fixed rate payments. Interest rate swaps can take a variety of other forms, such as agreements to pay the net differences between two different interest indexes or rates, even if the parties do not own the underlying instruments. Despite their differences in form, the function of interest rate swaps is generally the same: to increase or decrease a Fund’s exposure to long- or short-term interest rates. For example, a Fund may enter into a swap transaction to preserve a return or spread on a particular investment or a portion of its portfolio or to protect against any increase in the price of securities the Fund anticipates purchasing at a later date.
  •   The bitcoin exchanges on which bitcoin trades are relatively new and, in most cases, largely unregulated and, therefore, may be more exposed to volatility, fraud and security breaches than established, regulated exchanges for other products. 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. No Bitcoin Exchange is immune from these risks. Fraudulent activity can increase volatility and have an adverse effect on the price of bitcoin, the general acceptance of bitcoin as an investment or means of currency and could have a negative impact on the bitcoin futures contracts in which the Fund invests and the value of the Fund.
The first U.S. bitcoin futures are here. Bitcoin futures opened for trading on the Cboe Futures Exchange, LLC (CFE) on December 10, 2017. This is one of the biggest milestones for bitcoin since it emerged in the wake of the 2008-09 financial crisis. Bitcoin futures will bring much-needed transparency, greater liquidity and efficient price discovery to the ecosystem. Cboe will be soon joined by CME Group as it prepares to launch bitcoin futures contracts on December 18, 2017.
The Trust has entered into an agreement with Foreside Management Services, LLC (“Foreside”), pursuant to which Foreside provides the Trust with the services of an individual to serve as the Trust’s Principal Financial Officer and Treasurer. Neither Foreside nor the Treasurer have a role in determining the investment policies of the Trust or Funds, or which securities are to be purchased or sold by the Trust or a Fund. The Trust pays Foreside an annual flat fee of $100,000 per year and an additional annual flat fee of $3,500 per Fund, and will reimburse Foreside for certain out-of-pocket expenses incurred by Foreside in providing services to the Trust. For the fiscal years ended May 31, 2015, May 31, 2016 and May 31, 2017, the Trust paid $533,544, $533,860, and $481,869, respectively, to Foreside for services pursuant to its agreement. Foreside is located at Three Canal Plaza, Suite 100, Portland, ME 04101.

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.
  •   A person who exchanges Creation Units for securities generally will recognize a gain or loss equal to the difference between the exchanger’s basis in the Creation Units and the aggregate market value of the securities received and any cash received. However, all or a portion of any loss a person realizes upon an exchange of Creation Units for securities will be disallowed by the Internal Revenue Service if such person purchases other substantially identical shares of the Fund within 30 days before or after the exchange. In such case, the basis of the newly purchased shares will be adjusted to reflect the disallowed loss.
A Bitcoin futures contract is exactly what you would expect from the example above, replacing pork bellies with Bitcoin. It is a contract that enables you to buy Bitcoin at a predetermined price at a specific point in the future. For example, if today’s Bitcoin price is 8,000 USD per BTC and you expect it to rise to 10,000 USD per BTC in 4 weeks, then entering a contract which allows you to buy Bitcoin at 9,000 USD in 4 weeks is highly attractive.
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.

Inverse bitcoin contracts are usually denominated in USD terms. So if there's a contract value of $100 then each side -- LONG and SHORT -- puts down some portion of the contract value in margin. The contract is an agreement between traders to pay the other side an amount of bitcoin profit/loss as the price changes. Each contract has an expiration date, and some exchanges have periodic (daily or weekly) dates where the contract period's profits are "settled" even if the contract has not expired.
Investment income and gains received by a Fund from foreign investments may be subject to foreign withholding and other taxes, which could decrease the Fund’s return on those investments. The effective rate of foreign taxes to which a Fund will be subject depends on the specific countries in which its assets will be invested and the extent of the assets invested in each such country and, therefore, cannot be determined in advance. If more than 50% of a Fund’s assets at year end consists of the securities of foreign corporations, the Fund may elect to permit shareholders to claim a credit or deduction on their income tax returns for their pro rata portions of qualified taxes paid by the Fund to foreign countries in respect of foreign securities that the Fund has held for at least the minimum period specified in the Code. In such a case, shareholders will include in gross income from foreign sources their pro rata shares of such taxes paid by the Fund. A shareholder’s ability to claim an offsetting foreign tax credit or deduction in respect of foreign taxes paid by the Fund is subject to certain limitations imposed by the Code, which may result in the shareholder’s not receiving a full credit or deduction (if any) for the amount of such taxes. Shareholders who do not itemize on their U.S. federal income tax returns may claim a credit (but not a deduction) for such foreign taxes. Even if a Fund were eligible to make such an election for a given year, it may determine not to do so. Shareholders that are not subject to U.S. federal income tax, and those who invest in a Fund through tax-advantaged accounts (including those who invest through individual retirement accounts or other tax-advantaged retirement plans), generally will receive no benefit from any tax credit or deduction passed through by the Fund.
Note that the market value of the contract fluctuates before settlement. You are not forced to hold the contract to expiration. As the spot market moves, the traded futures contract price also moves. There is a live orderbook of traders placing buy and sell orders and you are able to realize your profit or loss prior to expiration, just as if you were buying and selling a stock.
BitMEX is a derivatives exchange that offers leveraged contracts that are bought and sold in Bitcoin. This is a platform that provides trading in bitcoin derivatives. The derivative traded is a perpetual swap contract, which is a derivative product similar to a traditional Futures Contract. Swap contracts trade like spots, tracking the underlying assets.

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.
Ziddu Coin is a smart contract that enables SME’s, processors, manufacturers, importers and exporters using cryptocurrencies across continents. Ziddu Coins are loosely pegged to Ethereum and Bitcoin. The importers/exporters convert offered Ziddu coins into Ethereum or Bitcoin and use the proceeds for their working capital needs. At the end of the contract, importers/exporters will realize their proceeds and pay back their funds through cryptocurrencies only. Depending upon the risk profile of the counterparty, the interest will vary from 12% to 48%.
You have to be the best story in the entire world of crypto currency that I have heard to date, and I have to say that you have got to be feeling about the best in your life! Congrats! I’m not anywhere near the same, but quite the opposite I might have to say. I’m learning as I go, and I have never been so dedicated to my success and I’m more interested in this as my possibly one chance to get to pay for the rest of my Mom’s mortgage and let her stop driving a school bus all to pay for a single signature that she was trying to get dinner for 7 as always and with 2&4 year old girls screaming and the stress that I now have as a little bit of motivation to help. Only one little signature from her husband and my step father, with no explanation, well, he’s passed on and the grieving process was not enough, she’s just been buried with a contract that she is the responsible person for the signature that 25 years later is a million dollar loan and the details are not my business but I’m told it has ballooned to be several million with the late fees and penalties… if you have any time to contact me please send me a message through Facebook or email. I just need a little more of a clear strategy and I just don’t have anyone to ask that has any level of success as you
  •   Risks Associated with Bitcoin – The Fund is exposed to risks associated with bitcoin. Investing in or gaining exposure to Bitcoin may provide the Fund with increased risk. Various global factors may negatively impact the Fund’s performance including legal, regulatory, political, social, regional and economic events. These risks, which could have a negative impact on the performance of the Fund and the trading price of Fund shares, include the following:

On 25 March 2014, the United States Internal Revenue Service (IRS) ruled that bitcoin will be treated as property for tax purposes. This means bitcoin will be subject to capital gains tax.[80] In a paper published by researchers from Oxford and Warwick, it was shown that bitcoin has some characteristics more like the precious metals market than traditional currencies, hence in agreement with the IRS decision even if based on different reasons.[81]

ProShare Advisors, pursuant to a separate Management Services Agreement, performs certain administrative services on behalf of the Funds, such as negotiating, coordinating and implementing the Trust’s contractual obligations with the Funds’ service providers; monitoring, overseeing and reviewing the performance of such service providers to ensure adherence to applicable contractual obligations; and preparing or coordinating reports and presentations to the Board of Trustees with respect to such service providers as requested or as deemed necessary. For these services, the Trust pays to ProShare Advisors a fee at the annual rate of 0.10% of average daily net assets for each of the Funds. ProShare Advisors has entered into an Advisory and Management Services Fee Waiver Agreement that waives this management services fee for the Morningstar Alternatives Solution ETF through at least October 31, 2018. Prior to this date, ProShare Advisors may not terminate the arrangement without the approval of the Board.

Two members of the Silk Road Task Force—a multi-agency federal task force that carried out the U.S. investigation of Silk Road—seized bitcoins for their own use in the course of the investigation.[86] DEA agent Carl Mark Force IV, who attempted to extort Silk Road founder Ross Ulbricht ("Dread Pirate Roberts"), pleaded guilty to money laundering, obstruction of justice, and extortion under color of official right, and was sentenced to 6.5 years in federal prison.[86] U.S. Secret Service agent Shaun Bridges pleaded guilty to crimes relating to his diversion of $800,000 worth of bitcoins to his personal account during the investigation, and also separately pleaded guilty to money laundering in connection with another cryptocurrency theft; he was sentenced to nearly eight years in federal prison.[87]

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.
•   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.
If a Fund purchases in the secondary market a debt security that has a fixed maturity date of more than one year from its date of issuance at a price lower than the stated redemption price of such debt security (or, in the case of a debt security issued with “original issue discount” (described below), a price below the debt security’s “revised issue price”), the excess of the stated redemption price over the purchase price is “market discount.” If the amount of market discount is more than a de minimis amount, a portion of such market discount must be included as ordinary income (not capital gain) by a Fund in each taxable year in which the Fund owns an interest in such debt security and receives a principal payment on it. In particular, the Fund will be required to allocate that principal payment first to the portion of the market discount on the debt security that has accrued but has not previously been includable in income. In general, the amount of market discount that must be included for each period is equal to the lesser of (i) the amount of market discount accruing during such period (plus any accrued market discount for prior periods not previously taken into account) or (ii) the amount of the principal payment with respect to such period. Generally, market discount accrues on a daily basis for each day the debt security is held by a Fund at a constant rate over the time remaining to the debt security’s maturity or, at the election of the Fund, at a constant yield to maturity which takes into account the semi-annual compounding of interest. Gain realized on the disposition of a market discount obligation must be recognized as ordinary interest income (not capital gain) to the extent of the accrued market discount.
When a new crypto is launched, its founders announce how many coins will be mined. Once the quota is reached, no further coins can be produced. The first digital coin introduced was Bitcoin, which remains today the benchmark for all other digital coins. Among other currencies that have made their way into the cryptocurrency hall-of-fame we have: Ethereum, Ripple, Litecoin, EOS, and a number of derived currencies, including Bitcoin Cash and Bitcoin Gold.

EDIT: #10 Bonus (Suggested by @kerstenwirth ) — always check the ticker symbol. Ticker symbols are not universal, and may vary from exchange to exchange in rare cases. Those cases, though, can come back to bite you. For example, Bitcoin Cash trades on some exchanges as BCH, while it trades on others as BCC. BCC is also the ticker symbol for BitConnect, which was recently outted as a Ponzi Scheme. If you bought BCC under the impression was Bitcoin Cash, you would’ve lost a lot of money.

•   Portfolio Turnover Risk — In seeking to meet its investment objective, the Fund may incur high portfolio turnover to manage the Fund’s investment exposure. Additionally, active market trading of the Fund’s shares may cause more frequent creation or redemption activities that could, in certain circumstances, increase the number of portfolio transactions. High levels of transactions increase brokerage and other transaction costs and may result in increased taxable capital gains.
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.

The proof-of-stake is a method of securing a cryptocurrency network and achieving distributed consensus through requesting users to show ownership of a certain amount of currency. It is different from proof-of-work systems that run difficult hashing algorithms to validate electronic transactions. The scheme is largely dependent on the coin, and there's currently no standard form of it. Some cryptocurrencies use a combined proof-of-work/proof-of-stake scheme.[18]
Here you will learn more broad concepts regarding daytrading bitcoin and futures in general. Even if you are not an active trader, there's a lot to learn about markets and how they're structured in this guide.  Some of the early sections may be a little too easy for those of you who already are traders, so just navigate through to the part that is most relevant to you if you want to hit a more advanced topic in the guide.
•   Credit Risk — The Fund could lose money if the issuer or guarantor of a fixed-income instrument or a counterparty to a derivatives transaction or other transaction is, or is perceived to be, unable or unwilling to pay interest, repay principal on time, or defaults. The value of an investment in the Fund may change quickly and without warning as a result of issuer defaults or actual or perceived changes in the credit ratings of the Fund’s portfolio investments or to an issuer’s financial strength.
Ripple is an open-source digital payment network, and it’s already being used by some of the world’s largest banks – such as the bank of Tokyo and Santandar. XRP has shown significant potential recently and has been turning a lot of heads. Ripple aims to become the go-to tool for banks on a global scale, while still giving an exciting investment opportunity to crypto advocates and solo investors. Ripple has many haters and I’ve been burned by it myself in the past – I sold 30,000 XRP at 20 cents… painful. Still, I did buy them at 3 cents a pop, so it could have been worse. I hold 10,000 XRP today and will hold until 2022.
the option to purchase the asset underlying the option at the exercise price if the option is exercised. During the term of the option, the writer may be assigned an exercise notice by the broker-dealer through whom the option was sold. The exercise notice would require the writer to deliver, in the case of a call, or take delivery of, in the case of a put, the underlying asset against payment of the exercise price. This obligation terminates upon expiration of the option, or at such earlier time that the writer effects a closing purchase transaction by purchasing an option covering the same underlying asset and having the same exercise price and expiration date as the one previously sold. Once an option has been exercised, the writer may not execute a closing purchase transaction. To secure the obligation to deliver the underlying asset in the case of a call option, the writer of a call option is required to deposit in escrow the underlying asset or other assets in accordance with the rules of the Options Clearing Corporation (the “OCC”), an institution created to interpose itself between buyers and sellers of options. The OCC assumes the other side of every purchase and sale transaction on an exchange and, by doing so, gives its guarantee to the transaction. When writing call options on an asset, a Fund may cover its position by owning the underlying asset on which the option is written. Alternatively, the Fund may cover its position by owning a call option on the underlying asset, on a share-for-share basis, which is deliverable under the option contract at a price no higher than the exercise price of the call option written by the Fund or, if higher, by owning such call option and depositing and segregating cash or liquid instruments equal in value to the difference between the two exercise prices. In addition, a Fund may cover its position by segregating cash or liquid instruments equal in value to the exercise price of the call option written by the Fund. When a Fund writes a put option, the Fund will segregate with its custodian bank cash or liquid instruments having a value equal to the exercise value of the option. The principal reason for a Fund to write call options on assets held by the Fund is to attempt to realize, through the receipt of premiums, a greater return than would be realized on the underlying assets alone.

The Funds are exchange-traded funds (“ETFs”) and the shares of each Fund (“Shares”) are listed on NYSE Arca, The NASDAQ Stock Market or the Bats BZX Exchange, Inc., (each, an “Exchange”). The Shares trade on the relevant Exchange at market prices that may differ to some degree from the Shares’ NAVs. Each Fund issues and redeems Shares on a continuous basis at NAV in large, specified numbers of Shares called “Creation Units.” Creation Units of the Funds are issued and redeemed in-kind for securities and an amount of cash or entirely in cash, in each case at the discretion of ProShare Advisors LLC (the “Advisor” or “ProShare Advisors”). Except when aggregated in Creation Units, Shares cannot be purchased from and are not redeemable securities of the Funds. Retail investors, therefore, generally will not be able to purchase or redeem the Shares directly. Rather, most retail investors will purchase and sell Shares in the secondary market with the assistance of a broker. Reference is made to the Prospectus for a discussion of the investment objectives and policies of each of the Funds. The discussion below supplements, and should be read in conjunction with, the Prospectus. Portfolio management is provided to the Funds by ProShare Advisors, a Maryland limited liability company with offices at 7501 Wisconsin Avenue, Suite 1000E, Bethesda, MD 20814.

Now, what if the Bitcoin price is rising? For example, if 1 BTC is worth 5,500 USD, you don’t want to fulfill this contract any more and sell cheap for 5,000 USD. In order to still make things fair for both participants, the exchange (here CME) will make sure that you can sell for the current market price of 5,500 USD if you so wish, but they will compensate your contract partner for this. How? They will take the difference – 500 USD – out of your so-called margin account and give it to Mortimer. This kind of settlement is not only performed on the fulfilment date of the futures contract, but on every trading day, according to the current price of the asset.
