In February 2014 the world's largest bitcoin exchange, Mt. Gox, declared bankruptcy. The company stated that it had lost nearly $473 million of their customers' bitcoins likely due to theft. This was equivalent to approximately 750,000 bitcoins, or about 7% of all the bitcoins in existence. The price of a bitcoin fell from a high of about $1,160 in December to under $400 in February.[85]
Daily Position Limit Risk - Many U.S. futures exchanges limit the amount of fluctuation permitted in futures contract prices during a single trading day. Once the daily limit has been reached in a particular contract, no trades may be made that day at a price beyond that limit or trading may be suspended for specified periods during the trading day. In addition, these exchanges have established limits on the maximum amount of futures positions that any person may hold or control on such exchanges. These limits may restrict the amount of assets the Fund is able to invest in bitcoin futures contracts or have a
Each Fund may provide redemptions in portfolio securities or cash at the Advisor’s discretion. With respect to the Matching and Ultra ProShares Funds, the Index Receipt Agent makes available through the NSCC immediately prior to the opening of business on the Exchange on each day that the Exchange is open for business the portfolio securities that will be applicable (subject to possible amendment or correction) to redemption requests received in proper form (as defined below) on that day (“Fund Securities”). These securities, at times, may not be identical to Deposit Securities which are applicable to a purchase of Creation Units. The Fund may also, in its sole discretion, upon request of a shareholder, provide such redeeming shareholder a portfolio of securities which differs from the exact composition of the Fund Securities but does not differ in NAV.
•   Any distributions from income or short-term capital gains that you receive generally are taxable to you as ordinary dividends for federal income tax purposes. Ordinary dividends you receive that a Fund reports as “qualified dividend income” may be taxed at the same rates as long-term capital gains, but will not be considered long-term capital gains for other federal income tax purposes, including the calculation of net capital losses.
In June 2015, the New York Department of Financial Services (the “NYDFS”) finalized a rule that requires most businesses involved in digital currency business activity in or involving New York, excluding merchants and consumers, to apply for a license (“BitLicense”) from the NYDFS and to comply with anti-money laundering, cyber security, consumer protection, and financial and reporting requirements, among others. As an alternative to the BitLicense in New York, firms can apply for a charter to become limited purpose trust companies qualified to engage in digital currency business activity. Other states have considered regimes similar to the BitLicense, or have required digital currency businesses to register with their states as money transmitters, such as Washington and Georgia, which results in digital currency businesses being subject to requirements similar to those of NYDFS’ BitLicense regime. Certain state regulators, such as the Texas Department of Banking, Kansas Office of the State Bank Commissioner and the Illinois Department of Financial and Professional Regulation, have found that mere transmission of bitcoin, without activities involving transmission of fiat currency, does not constitute money transmission requiring licensure. The North Carolina Commissioner of Banks has issued guidance providing that North Carolina’s money transmission regulations only apply to the transmission of digital currency and not its use. In June 2014, the State of California adopted legislation that would formally repeal laws that could be interpreted as making illegal the use of bitcoin or other digital assets as a means of payment. In July 2017, Delaware amended its General Corporation Law to provide for the creation maintenance of certain required records by blockchain technology and permit its use for electronic transmission of stockholder communications.
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.

“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 invest in a wide range of fixed income securities, which may include foreign sovereign, sub-sovereign and supranational bonds, as well as any other obligations of any rating or maturity such as foreign and domestic investment grade corporate debt securities and lower-rated corporate debt securities (commonly known as “junk bonds”). Lower-rated or high yield debt securities include corporate high yield debt securities, zero-coupon securities, payment-in-kind securities, and STRIPS. Investment grade corporate bonds are those rated BBB or better by Standard & Poor’s Rating Group (“S&P”) or Baa or better by Moody’s Investor Services (“Moody’s”). Securities rated BBB by S&P are considered investment grade, but Moody’s considers securities rated Baa to have speculative characteristics. See Appendix A for a description of corporate bond ratings. The Funds may also invest in unrated securities.
Most traders who do not have a plan for trading blindly will be eliminated in the near future. As a transaction, bitcoin trading is no different from other underlying objects, such as stock futures. An effective trading strategy is essential in order to make a steady profit in this market. Stop the loss of profits, homeopathy, light warehouse is the key. To strictly implement these trading plan, use the program trading is very effective, program trading my first contact with bitcoin is BotVS quantification in the know the platform to see the column introduced bitcoin hedging strategy is inspired by. Later, I tried to write some trading strategies and use them on firm exchanges. Accumulated a lot of bitcoin trading experience. I’m still bullish on bitcoin, which was a great invention in the twenty-first Century.
​Trading these futures instead of actual bitcoins is smart because you are able to access higher leverage by entering contracts with counterparties, while keeping your coins safe in cold storage or elsewhere. Additionally, unlike trading margin on Kraken or Bitfinex, you do NOT have to pay interest on the leverage you have! This is the result of the counterparty structure of futures. High leverage trading, low-fees, and high profit potential.
Maintenance Margin - this is the % of the position value you have to have in your account at the very minimum to avoid being Margin Called.  In some exchanges, margin call will mean you get notified and must deposit more margin to avoid liquidation (like CryptoFacilities). On other exchanges you will at this point be liquidated out of your position. So if maintenance margin is 5%, then the 0.05 BTC of your initial margin will need to be kept for the position to be alive.
Each Fund has adopted certain investment restrictions as fundamental policies that cannot be changed without a “vote of a majority of the outstanding voting securities” of the Fund. The phrase “majority of outstanding voting securities” is defined in the 1940 Act as the lesser of: (i) 67% or more of the shares of the Fund present at a duly-called meeting of shareholders, if the holders of more than 50% of the outstanding shares of the Fund are present or represented by proxy; or (ii) more than 50% of the outstanding shares of the Fund. (All policies of a Fund not specifically identified in this Statement of Additional Information or its Prospectus as fundamental may be changed without a vote of the shareholders of the Fund.) For purposes of the following limitations, all percentage limitations apply immediately after a purchase or initial investment.
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.

Sia is the very first decentralized storage platform that’s based on and secured by the blockchain technology. Through the blockchain tech, Sia can provide much reliable data storage options that do not have a single point of failure, can offer more storage space – at much lower costs than traditional cloud storage providers. Besides the obvious, investors are readily jumping on the Sia-train for one more reason: Privacy. Unlike cloud-storage provides, Sia’s tech gives you all the keys to your own (encrypted) data, and mandates that no third party will control nor access your files.
A Bitcoin (spot or futures) exchange (like any online trading firm) charges its clients a fee to carry out trading activities. As exchanges face the risk of hacking and theft, it is wise not to trust an exchange with all your coins. You should split and keep part of them in other devices or cold storage. Now with bitcoin futures being offered by some of the most prominent marketplaces, investors, traders and speculators are all bound to benefit. These centralized marketplaces will facilitate trade based on a trader’s outlook for bitcoin prices, gain exposure to bitcoin prices or hedge their existing bitcoin positions. Overall, the launching of bitcoin futures by Cboe and CME will facilitate price discovery and price transparency, enable risk-management via a regulated bitcoin product and give a further push to bitcoin as an accepted asset class. (For more, see: The Risks Of Buying Bitcoins.)
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.
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.

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 ICON technology (ICX) is incredibly exciting because it aims to harbor the single largest decentralized global network. It aims to provide its users a certain degree of connectivity between countries and cultures around the world that’s currently just not possible or non-existent. This network gives way to businesses and individuals to communicate, transfer, deposit, and in many different ways cooperate with each other in a never seen before way. ICON shows extraordinary potential for the future, but it’s already boasting a large community made of reputable security institutions, banks, hospitals, insurances, universities and institutions in many other sectors. Crucially, ICON is NOT yet tradable in South Korea – when that changes I expect this coin to moon.
•   In order to qualify for the special tax treatment accorded a regulated investment company (“RIC”) and its shareholders, a Fund must derive at least 90% of its gross income for each taxable year from “qualifying income,” meet certain asset diversification tests at the end of each taxable quarter, and meet annual distribution requirements. A Fund’s 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. A Fund can make certain investments, the treatment of which for these purposes is unclear. If, in any year, a 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. Please see the Statement of Additional Information for more information.
Futures markets create an immense amount of flexibility. They enable investors to readily bet on an asset or bet against it (go long or go short), and they are usually characterised by an immense amount of leverage. In the case of bitcoin, this means one can trade a high volume of coins while only paying for a fraction of them, essentially operating with borrowed money. Leverage is used to amplify profits on a small volume of assets, but it is a double-edged sword in that it also amplifies losses.
Altcoins is the general term associated with the cryptocurrencies launched after Bitcoin’s success. At first, these were mere copies mimicking the original Bitcoin. Today, there are over 1,000 of these, and the list just keeps growing. Most crypto coins are launched following an ICO (Initial Coin Offering – a form of crowdfunding) in which the developers raise cash by offering a limited number of initial coins to finance technological development. So far, besides the list below, we can find names, such as Namecoin, Peercoin, Bytecoin, Deutsche eMark, Novacoin, Cryptogenic Bullion, Quark, DarkCoin and Mangocoinz (for smartphones).
Because of the wide range of types and maturities of corporate debt securities, as well as the range of creditworthiness of its issuers, corporate debt securities have widely varying potentials for return and risk profiles. For example, commercial paper issued by a large established domestic corporation that is rated investment-grade may have a modest return on principal, but carries relatively limited risk. On the other hand, a long-term corporate note issued by a small foreign corporation from an emerging market country that has not been rated may have the potential for relatively large returns on principal, but carries a relatively high degree of risk.
On October 31, 2017, CME Group, the world's leading and most diverse derivatives marketplace, had announced its intent to launch bitcoin futures in the fourth quarter of 2017. “CME Group's Bitcoin futures will be available for trading on the CME Globex electronic trading platform, and for submission for clearing via CME ClearPort, effective on Sunday, December 17, 2017 for a trade date of December 18” as per CME’s officials statement.
  •   A new competing digital asset may pose a challenge to bitcoin’s current market dominance, resulting in a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin. It is possible that other digital currencies and trading systems could become more widely accepted and used than Bitcoin. The rise of such currencies could lead to a reduction in demand for bitcoin, which could have a negative impact on the price of bitcoin.

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:
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.
