A cryptocurrency (or crypto currency) is a digital asset designed to work as a medium of exchange that uses strong cryptography to secure financial transactions, control the creation of additional units, and verify the transfer of assets.[1][2][3] Cryptocurrencies are a kind of alternative currency and digital currency (of which virtual currency is a subset). Cryptocurrencies use decentralized control[4] as opposed to centralized digital currency and central banking systems.[5] The decentralized control of each cryptocurrency works through distributed ledger technology, typically a blockchain, that serves as a public financial transaction database.[6][7]
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.

While cryptocurrencies are digital currencies that are managed through advanced encryption techniques, many governments have taken a cautious approach toward them, fearing their lack of central control and the effects they could have on financial security.[99] Regulators in several countries have warned against cryptocurrency and some have taken concrete regulatory measures to dissuade users.[100] Additionally, many banks do not offer services for cryptocurrencies and can refuse to offer services to virtual-currency companies.[101] Gareth Murphy, a senior central banking officer has stated "widespread use [of cryptocurrency] would also make it more difficult for statistical agencies to gather data on economic activity, which are used by governments to steer the economy". He cautioned that virtual currencies pose a new challenge to central banks' control over the important functions of monetary and exchange rate policy.[102] While traditional financial products have strong consumer protections in place, there is no intermediary with the power to limit consumer losses if bitcoins are lost or stolen.[103] One of the features cryptocurrency lacks in comparison to credit cards, for example, is consumer protection against fraud, such as chargebacks.


While volatile movements take away the attractiveness of any asset, a certain amount of swing in price creates trading opportunities. This is something that many traders and speculators have been taking advantage of by buying the digital currency and then selling at a profit through an exchange. The whole process makes bitcoin exchanges an important part of the ecosystem since it facilitates the buying and selling of bitcoins, as well as futures trading.

An Authorized Participant that wishes to place an order to purchase Creation Units outside the Clearing Process must state that it is not using the Clearing Process and that the purchase instead will be effected through a transfer of securities and cash directly through DTC or as described below for Global Funds (defined below). Purchases (and redemptions) of Creation Units of the Matching and Ultra ProShares Funds settled outside the Clearing Process will be subject to a higher Transaction Fee than those settled through the Clearing Process. Purchase orders effected outside the Clearing Process are likely to require transmittal by the Authorized Participant earlier on the transmittal date than orders effected using the Clearing Process. Those persons placing orders outside the Clearing Process should ascertain the deadlines applicable to DTC and the Federal Reserve Bank wire system by contacting the operations department of the broker or depository institution effectuating such transfer of Deposit Securities and Balancing Amount (for the Matching and Ultra ProShares Funds), each as applicable and at the discretion of the Advisor, or of the Cash Purchase Amount together with the applicable Transaction Fee.

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.


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.

Each Fund may engage in transactions in index options listed on national securities exchanges or traded in the OTC market as an investment vehicle for the purpose of realizing the Fund’s investment objective. The exercising holder of an index option receives, instead of the asset, cash equal to the difference between the closing level of the index and the exercise price of the option. Some index options are based on a broad market index such as the Standard & Poor’s (“S&P”) 500® Index, the New York Stock Exchange, Inc. (“NYSE”) Composite Index or on a narrower index such as the Philadelphia Stock Exchange Over-the-Counter Index. Options currently are traded on the Chicago Board Options Exchange, the NYSE Amex Options and other exchanges (collectively, “Exchanges”). Purchased OTC options and the cover for written OTC options will be subject to the relevant Fund’s 15% limitation on investment in illiquid securities. See “Illiquid Securities” below. When required by law, a Fund will segregate liquid assets in an amount equal to the value of the Fund’s total assets committed to the consummation of such options. Obligations under options so covered will not be considered senior securities for purposes of a Fund’s investment restriction concerning senior securities.

Don’t invest blindy. There are people in this world who would sell a blind person a pair of glasses if they could make money. Those same people play in the cryptocurrency markets and use every opportunity to exploit less-informed investors. They’ll tell you what to buy or claim certain coins will moon, just to increase the prices so they can exit. Due to the highly speculative nature of the cryptocurrency markets today, a good investor will always do his or her own research in order to take full responsibility for the potential investment outcome. Information coming from even the best investor is, at best, great information, but never a promise, so you can still get burned.
Below is a description of various types of money market instruments and other debt instruments that a Fund may utilize for investment purposes, as “cover” for other investment techniques such Fund employs, or for liquidity purposes. Other types of money market instruments and debt instruments may become available that are similar to those described below and in which the Funds also may invest consistent with their investment goals and policies. Each Fund may also invest in pooled investment vehicles that invest in, and themselves qualify as, money market instruments.
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.
“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.”

Around the same time, Nick Szabo, a computer scientist who now blogs about law and the history of money, was one of the first to imagine a new digital currency from the ground up. Although many consider his scheme, which he calls “bit gold,” to be a precursor to Bitcoin

In 1998, Wei Dai published a description of "b-money", an anonymous, distributed electronic cash system.[14] Shortly thereafter, Nick Szabo created "bit gold".[15] Like bitcoin and other cryptocurrencies that would follow it, bit gold (not to be confused with the later gold-based exchange, BitGold) was an electronic currency system which required users to complete a proof of work function with solutions being cryptographically put together and published. A currency system based on a reusable proof of work was later created by Hal Finney who followed the work of Dai and Szabo.


  •   Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “Bitcoin Improvement Proposals”, or “BIPs.” If accepted by a sufficient number of miners, BIPs may result in substantial changes to the Bitcoin Network, including changes that result in “forks.” Such changes may influence the price of Bitcoin and Bitcoin Futures Contracts. In particular, it is possible that the price of the Bitcoin Futures Contracts subsequent to a “fork” may be linked to the price of bitcoin on only one of the resulting Bitcoin Networks, rather than the aggregate price of bitcoin on all resulting Bitcoin Networks. The CBOE Futures Exchange (“CFE”) and Chicago Mercantile Exchange (“CME”) have announced different protocols for addressing forks.

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).
  (c) A “Disinterested Trustee” is one (i) who is not an Interested Person of the Trust (including anyone, as such Disinterested Trustees, who has been exempted from being an Interested Person by any rule, regulation or order of the Commission), and (ii) against whom none of such actions, suits or other proceedings or another action, suit or other proceeding on the same or similar grounds is then or has been pending;
  5. Borrow money, except that the Fund (i) may borrow from banks (as defined in the 1940 Act) in amounts up to 331/3% of its total assets (including the amount borrowed), (ii) may, to the extent permitted by applicable law, borrow up to an additional 5% of its total assets for temporary purposes, (iii) may obtain such short-term credit as may be necessary for the clearance of purchases and sales of portfolio securities, (iv) may purchase securities on margin to the extent permitted by applicable law and (v) may enter into reverse repurchase agreements. The Fund may not pledge its assets other than to secure such borrowings or, to the extent permitted by the Fund’s investment policies as set forth in the Prospectus and SAI, as they may be amended from time to time, in connection with hedging transactions, short sales, when-issued and forward commitment transactions and similar investment strategies.
Currently there are a several digital asset trading platforms that provide investors with forms of derivative products such as futures, so one could estimate and synthesize the discrete futures curve from the averages of various curves. MVIS research used BitMEX, OKCoin, CryptoFacilities, and BTCC as sources, to construct and approximate bitcoin futures curve based on non-U.S. bitcoin futures trading on these exchanges.

ProShare Advisors is also responsible for the general management and administration of each Subsidiary, pursuant to separate investment advisory and management agreements. Under those advisory and management agreements, ProShare Advisors provides each Subsidiary with the same type of services under essentially the same terms (except at no cost to such Subsidiary) as are provided for its respective Parent Fund.
•   Liquidity Risk — In certain circumstances, such as the disruption of the orderly markets for the bitcoin futures contracts in which the Fund invests, the Fund might not be able to acquire or dispose of certain holdings quickly or at prices that represent true market value in the judgment of ProShare Advisors. Markets may be disrupted by a number of events, including but not limited to cyber-attacks, economic crises, natural disasters, new legislation, or regulatory changes inside or outside the U.S.
Although forward currency contracts may be used by the Funds to try to manage currency exchange risks, unanticipated changes in currency exchange rates could result in poorer performance than if a Fund had not entered into these transactions. Even if the Advisor correctly predicts currency exchange rate movements, a hedge could be unsuccessful if changes in the value of a Fund’s position do not correspond to changes in the value of the currency in which its investments are denominated. This lack of correlation between a Fund’s forwards and currency positions may be caused by differences between the futures and currency markets.
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 price of bitcoin on individual bitcoin exchanges, as well as the broader Bitcoin Exchange Market generally, has experienced periods of extreme volatility. This volatility is due in part to low liquidity and the changes exhibited by an early stage technological innovation. Speculators and investors who seek to profit from trading and holding bitcoin currently account for a significant portion of bitcoin demand. Such speculation regarding the potential future appreciation in the value of bitcoin may artificially inflate the price of bitcoin causing a negative impact on the performance of certain Funds which take a short position in bitcoin futures contracts. Conversely, government regulation and the perception of onerous regulatory actions may cause a drop in the price of bitcoin causing a negative impact on the performance of certain Funds which take a long position in bitcoin futures contracts. Developments related to the Bitcoin Network’s operations, Bitcoin Exchanges and the overall Bitcoin Exchange Market also contribute to the volatility in the price of bitcoin. These factors may continue to increase the volatility of the price of bitcoin which may have a negative impact on the performance of the Bitcoin Instruments and on the performance of the Funds.

Anyone interested in buying bitcoins needs to deposit funds in U.S. dollars, euros, or another currency supported by the exchange. The popular methods of transferring money to the currency exchanges are through bank wire transfers, credit cards, or liberty reserves. One of the pre-requisites here is to have a digital wallet to hold bitcoins. Bitcoins bought can be stored in a digital wallet, device, or paper wallet, depending on the buyer’s preference. For sellers, the fait currency for which the Bitcoins have been sold needs to be withdrawn from the exchange and sent to a bank. One issue that can arise is if the exchange has liquidity concerns at a particular point in time; such situations can delay withdrawal and transfer of funds into a bank account. (For more, see: A Look At The Most Popular Bitcoin Exchanges.)
Distributions of investment income are generally taxable to shareholders as ordinary income. Taxes on distributions of capital gains are determined by how long a Fund owned the investments that generated them, rather than how long a shareholder has owned his or her shares. In general, a Fund will recognize long-term capital gain or loss on investments it has owned for more than one year, and short-term capital gain or loss on investments it has owned for one year or less. Tax rules can alter a Fund’s holding period in investments and thereby affect the tax treatment of gain or loss on such investments. Distributions of net capital gain – the excess of net long-term capital gain over net short-term capital losses, in each case determined with reference to any loss carryforwards – that are properly reported by the Fund as capital gain dividends (“Capital Gain Dividends”) will be taxable to shareholders as long-term capital gains includible in net capital gain and taxable to individuals at reduced rates. Distributions of net short-term capital gain (as reduced by any net long-term capital loss for the taxable year) will be taxable to shareholders as ordinary income.
Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities may fluctuate more in response to interest rate changes than securities with shorter maturities. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary policies, inflation rates, general economic conditions, etc.). This risk may be elevated under current economic conditions because interest rates are at historically low levels. Returns on investment in debt instruments may trail the returns on other investment options, including investments in equity securities.

On December 1, 2017, the CFTC issued a statement concerning the launch of bitcoin futures contracts on three CFTC-regulated futures exchanges – the CME, the CFE and the Cantor Exchange, cautioning that “market participants should take note that the relatively nascent underlying cash markets and exchanges for bitcoin remain largely unregulated markets over which the CFTC has limited statutory authority. There are concerns about the price volatility and trading practices of participants in these markets. We
An Authorized Participant may place an order to purchase (or redeem) Creation Units (i) through the Continuous Net Settlement clearing processes of NSCC as such processes have been enhanced to effect purchases (and redemptions) of Creation Units, such processes being referred to herein as the “Clearing Process,” or (ii) outside the Clearing Process, though orders for Global Funds (as defined below) may not be placed through the Clearing Process. In either case, a purchase order for a Fund must be received by the following cut-off times (which may be earlier if the relevant Exchange or any relevant bond market closes early). In all cases purchase/redeem procedures are at the discretion of the Advisor and may be changed without notice.
Margin-trading is what provides the real reward and potential in daytrading bitcoin. You will be able to access the leverage to profit well from relatively small moves in BTC/USD price. High risk, high reward, high potential for loss. However, you need not use Futures only to speculate, hedging on lower leverage is also a great use case for Bitcoin derivatives if you just want to defend your coins. 
•   Rolling Futures Contract Risk — The Fund will invest in and have exposure to bitcoin futures contracts and is subject to risks related to “rolling” such contracts. Rolling occurs when the Fund closes out of a futures contract as it nears its expiration and replaces it with a contract that has a later expiration. The Fund does not intend to hold futures contracts through expiration, but instead intends to “roll” its futures positions. When the market for these futures contracts is such that the prices are higher in the more distant delivery months than in the nearer delivery months, the sale during the course of the rolling process of the more nearby contract would take place at a price that is lower than the price of the more distant contract. This pattern of higher futures contract prices for longer expiration contracts is often referred to as “contango.” Alternatively, when the market for futures contracts is such that the prices are higher in the nearer months than in the more distant months, the sale during the course of the rolling process of the more nearby contract would take place at a price that is higher than the price of the more distant contract. This pattern of higher futures prices for shorter expiration futures contracts is referred to as “backwardation.” Extended periods of contango could cause significant losses for the Fund. The Advisor will utilize active management techniques to seek to mitigate the negative impact or, in certain cases, benefit from the contango or backwardation present in the various futures contract markets, but there can be no guarantee that it will be successful in doing so.
Knowing their estimated costs and profit requirements the arbitrageur determines a minimum difference they need between the futures’ prices and the spot price before they will enter the market. They then monitor the price difference between Bitcoin futures and the Bitcoin exchanges and if large enough they act to profit on that gap.  For example, if a specific Bitcoin future (e.g., February contract) is trading sufficiently higher than the current Bitcoin exchange price they will short that Bitcoin future and hedge their position by buying Bitcoins on the exchange. At that point, if they have achieved trade prices within their targets, they have locked in a guaranteed profit. They will hold those positions until contract expiration (or until they can cover their short futures and sell Bitcoins at a profit).
