Ethereum (ETH) is more than just a currency – it’s like one giant computer housing many computers around the globe. Ethereum can respond to sophisticated requests. Its ability to store revolutionary computer programs, known as smart contracts, gives Ethereum an edge over Bitcoin and has attracted attention from banks around the world. This, among other factors, has led to a jump of almost 10,000% in 2017!
Now let's say that both traders simply hold the January 9 contract to expiration. If price settles at 440, 10% higher, then Bob will get a 50% return on his initial margin (+0.1btc, 5x leverage enhances his 10% gain on the notional 1 bitcoin of the contract) and Ann will lose 50%. (-0.1btc). This is one of the most powerful parts of futures: higher leverage means higher returns on your trades. The leverage feature is essential for hedgers and speculators trying to get the most out of their capital when managing risk. And better yet: you don't pay daily interest or any margin fees on this leverage with bitcoin futures!

THIS MATERIAL HAS BEEN PREPARED BY A FUTURESONLINE BROKER WHO PROVIDES RESEARCH MARKET COMMENTARY AND TRADE RECOMMENDATIONS AS PART OF HIS OR HER SOLICITATION FOR ACCOUNTS AND SOLICITATION FOR TRADES. FUTURESONLINE, ITS PRINCIPALS, BROKERS AND EMPLOYEES MAY TRADE IN DERIVATIVES FOR THEIR OWN ACCOUNTS OR FOR THE ACCOUNTS OF OTHERS. DUE TO VARIOUS FACTORS (SUCH AS RISK TOLERANCE, MARGIN REQUIREMENTS, TRADING OBJECTIVES, SHORT TERM VS. LONG TERM STRATEGIES, TECHNICAL VS. FUNDAMENTAL MARKET ANALYSIS, AND OTHER FACTORS) SUCH TRADING MAY RESULT IN THE INITIATION OR LIQUIDATION OF POSITIONS THAT ARE DIFFERENT FROM OR CONTRARY TO THE OPINIONS AND RECOMMENDATIONS CONTAINED THEREIN.
If Bitcoin futures prices get too high relative to spot arbitragers are natural sellers and if the futures prices get too low they are natural buyers. Their buying and selling actions naturally counteract price distortions between markets. If they’re somehow prevented from acting (e.g., if shorting Bitcoin was forbidden) then the futures market would likely become decoupled from the underlying spot price—not a good thing.
•	 	Active Management Risk — The performance of actively managed funds reflects, in part, the ability of ProShare Advisors to select investments and make investment decisions that are suited to achieving the Fund’s investment objective. ProShare Advisors’ judgments about the Fund’s investments may prove to be incorrect. If the investments selected and strategies employed by ProShare Advisors fail to produce the intended results, the Fund may not achieve its investment objective and could underperform other funds with a similar investment objective and/or strategies.

You will then be able to trade futures contracts just like they are bitcoin spot. If price goes up on spot, a good futures exchange will have its contracts also going up in price, and then you can sell and get out. However, the price of the futures contract is dependent on others trading it. So if nobody else is trading it and bringing the market price of the contract along with changes in the underlying asset, then it's useless and you are forced to hold it until settlement to realize any of the profit/loss from the position.
In order to qualify for the withholding exemptions for interest-related and short term capital gain dividends, a foreign shareholder is required to comply with applicable certification requirements relating to its non-U.S. status (including, in general, furnishing the applicable W-8 form or substitute form). In the case of shares held through an intermediary, the intermediary may withhold even if the Fund reports all or a portion of a payment as an interest-related or short-term capital gain dividend to shareholders. Foreign shareholders should consult their tax advisors or intermediaries, as applicable, regarding the application of these rules to their accounts.

The Board has approved a Distribution and Service Plan under which each Fund may pay financial intermediaries such as broker-dealers and investment advisers (“Authorized Firms”) up to 0.25%, on an annualized basis, of average daily net assets of the Fund as reimbursement or compensation for distribution-related activities with respect to the Shares of the Fund and shareholder services. Under the Distribution and Service Plan, the Trust or the Distributor may enter into agreements (“Distribution and Service Agreements”) with Authorized Firms that purchase Shares on behalf of their clients.
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.
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.
That's why liquidity and volume are essential to a quality exchange. If you enter that contract at $400 and you see bitcoin spot price jumping to $500 but nobody is trading futures so you can't sell it to them, you get screwed. Luckily at this point in 2016 there are numerous options for trading futures that are liquid and settle on short time horizons. So you can typically trade contracts and get in and out of them with decent spreads and reasonable fees.
If the price drops to $500, you earn 11.73 BTC on the position and have 20.06 BTC left, which at $500 per BTC is worth $10,000! This is a simple example just to show you, even if you're a small bitcoin holder, bitcoin futures are a valuable risk management tool. You could have performed this "hedge" at 50x leverage by putting down just 8.33/50= 0.17 BTC worth of margin!
The most common way to trade in Bitcoin and other cryptocurrency derivatives today is through contract-for-difference (CFD) contracts. These CFD contracts are usually traded over the counter (OTC), meaning that they are not traded on exchanges but directly between participants. Due to the high volatility (exceeding 1.5-2x std from the mean) most of the OTC platforms do not provide leverage on bitcoin and other cryptos CFDs.
•   Small-and Mid-Cap Company Investment Risk — The Fund may invest in stocks of small-and mid-cap companies. The risk of equity investing may be particularly acute for securities of issuers with smaller market capitalizations. Small-and mid-cap company stocks may trade at greater spreads or lower trading volumes, and may be less liquid than the stocks of larger companies. Small-and mid-cap companies may have limited product lines or resources, may be dependent upon a particular market niche and may have greater fluctuations in price than the stocks of larger companies. Further, stocks of small-and mid-sized companies could be more difficult to liquidate during market downturns compared to larger, more widely traded companies. In addition, small-and mid-cap companies may lack the financial and personnel resources to handle economic or industry-wide setbacks and, as a result, such setbacks could have a greater effect on small-and mid-cap security prices.
  •   The technology is new and many of its uses may be untested. Blockchain technology is a new and developing technology protocol that is relatively untested and unregulated. The mechanics of using distributed ledger technology to transact in other types of assets, such as securities or derivatives, is less clear. Blockchain technology may never develop optimized transactional processes that lead to realized economic returns for any company in which the Fund invests.

Shares will be continuously offered for sale by the Trust through the Distributor only in Creation Units, as described below under “Purchase and Issuance of Creation Units.” Shares in less than Creation Units are not distributed by the Distributor. The Distributor also acts as agent for the Trust. The Distributor will deliver a Prospectus to persons purchasing Shares in Creation Units and will maintain records of both orders placed with it and confirmations of acceptance furnished by it. The Distributor is a broker-dealer registered under the 1934 Act and a member of the Financial Industry Regulatory Authority, Inc. The Distributor has no role in determining the investment policies of the Funds or which securities are to be purchased or sold by the Funds.
•   Foreign Investments Risk — Investing in securities of foreign issuers may provide the Fund with increased risk. Various factors related to foreign investments may negatively impact the Fund’s performance, such as: i) fluctuations in the value of the applicable foreign currency; ii) differences in securities settlement practices; iii) uncertainty associated with evidence of ownership of investments in countries that lack centralized custodial services; iv) possible regulation of, or other limitations on, investments by U.S. investors in foreign investments; v) potentially higher brokerage commissions; vi) the possibility that a foreign government may withhold portions of interest and dividends at the source; vii) taxation of income earned in foreign countries or other foreign taxes imposed; viii) foreign exchange controls, which may include suspension of the ability to transfer currency from a foreign country; ix) less publicly available information about foreign issuers; x) changes in the denomination currency of a foreign investment; and xi) less certain legal systems in which the Fund might encounter difficulties or be unable to pursue legal remedies. Foreign investments also may be more susceptible to political, social, economic and regional factors than might be the case with U.S. securities. In addition, markets for foreign investments are usually less liquid, more volatile and significantly smaller than markets for U.S. securities, which may affect, among other things, the Fund’s ability to purchase or sell foreign investments at appropriate times. Because of differences in settlement times and/or foreign market holidays, transactions in a foreign market may take place one or more days after the necessary exposure to these investments is determined. Until the transactions are effected, the Fund is exposed to increased foreign currency risk and market risk.
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.
Almost every crypto-list today starts off with the king – Bitcoin! Satoshi Nakamoto created Bitcoin a long time ago, and it was the first cryptocurrency to step blinking into the bright light of the world! Bitcoin has surpassed all expecatations and continues to grow in value and popularity – despite recent setbacks and a lot of FUD from trolls and haters (read: traditional banks) online.  Will Bitcoin continue to increase in value in 2018? Recent trends say: Yes! In my opinion, any cryptocurrency portfolio should hold some Bitcoin.

Do you remember, like, two weeks ago, when people were talking about how the launch of bitcoin futures at Cboe Global Markets Inc. and CME Group Inc. would allow for efficient short-selling of bitcoin and finally deflate the bubble? Smart hedge-fund money was lining up to bet against bitcoin, the thinking went, but had no convenient way to do it on the actual bitcoin exchanges. The only people trading bitcoin were the true believers, so of course it kept going up, but once it was opened up to normal financial players that would end. "The futures reduce the frictions of going short more than they do of going long, so it’s probably net bearish," said Craig Pirrong. 


Investment in mortgage-backed securities poses several risks, including among others, prepayment, market and credit risk. Prepayment risk reflects the risk that borrowers may prepay their mortgages faster than expected, thereby affecting the investment’s average life and perhaps its yield. Whether or not a mortgage loan is prepaid is almost entirely controlled by the borrower. Borrowers are most likely to exercise prepayment options at the time when it is least advantageous to investors, generally prepaying mortgages as interest rates fall, and slowing payments as interest rates rise. Besides the effect of prevailing interest rates, the rate of prepayment and refinancing of mortgages may also be affected by appreciation in home values, ease of the refinancing process and local economic conditions. Market risk reflects the risk that the price of a security may fluctuate over time. The price of mortgage-backed securities may be particularly sensitive to prevailing interest rates, the length of time the security is expected to be outstanding, and the liquidity of the issue. In a period of unstable interest rates, there may be decreased demand for certain types of mortgage-backed securities, and each Fund invested in such securities wishing to sell them may find it difficult to find a buyer, which may in turn decrease the price at which they may be sold. Credit risk reflects the risk that a Fund may not receive all or part of its principal because the issuer or credit enhancer has defaulted on its obligations. Obligations issued by U.S. government-related entities are guaranteed as to the payment of principal and interest, but are not backed by the full faith and credit of the U.S. government. The performance of private label mortgage-backed securities, issued by private institutions, is based on the financial health of those institutions. With respect to GNMA certificates, although GNMA guarantees timely payment even if homeowners delay or default, tracking the “pass-through” payments may, at times, be difficult.

Under certain circumstances, a Fund may recognize gain from a constructive sale of an “appreciated financial position” it holds if it enters into a short sale, forward contract or other transaction that substantially reduces the risk of loss with respect to the appreciated position. In that event, the Fund would be treated as if it had sold and immediately repurchased the property and would be taxed on any gain (but would not recognize any loss) from the constructive sale. The character of gain from a constructive sale would depend upon each Fund’s holding period in the property. Appropriate adjustments would be made in the amount of any gain or loss subsequently realized on the position to reflect the gain recognized on the constructive sale. Loss from a constructive sale would be recognized when the property was subsequently disposed of, and its character would depend on the Fund’s holding period and the application of various loss deferral provisions of the Code. Constructive sale treatment does not generally apply to a transaction if such transaction is closed on or before the end of the 30th day after the close of the Fund’s taxable year and the Fund holds the appreciated financial position throughout the 60-day period beginning with the day such transaction closed. The term “appreciated financial position” excludes any position that is “marked-to-market.”


The identity and number of shares of the Deposit Securities required for a Portfolio Deposit for each Fund changes as rebalancing adjustments and corporate action events are reflected from time to time by ProShare Advisors with a view to the investment objective of the applicable Fund. The composition of the Deposit Securities may also change in response to adjustments to the weighting or composition of the securities constituting the relevant securities index, as applicable. The adjustments described above will reflect changes, known to ProShare Advisors on the date of announcement to be in effect by the time of delivery of the Portfolio Deposit, in the composition of the subject index being tracked by the relevant Fund, as applicable, or resulting from stock splits and other corporate actions. In addition, the Trust reserves the right to permit or require the substitution of an amount of cash (i.e., a “cash in lieu” amount) to be added to the Balancing Amount to replace any Deposit Security which may not be available in sufficient quantity for delivery or for other similar reasons. A Transaction Fee may be assessed on any “cash in lieu” amounts, as further described below under “Transaction Fees”. For the High Yield—Interest Rate Hedged, the Investment Grade—Interest Rate Hedged and the Short Term USD Emerging Markets Bond ETF, a minimum of 70% of the Deposit Securities must be delivered, unless such purchase is made on a cash-only basis.
Those who believe in Cryptocurrency claim it to be the next big thing in the history of mankind. The mere fact that Cryptocurrency is beyond the control of any government body gets it a lot of eyeballs. Imagine a universal currency beyond the control of liquidity, inflation and government subsidy. This would mean that the commercial activity of economies working on Cryptocurrency shall be privatized absolutely.
Distributions by the Fund to foreign shareholders other than Capital Gain Dividends, short-term capital gain dividends and interest-related dividends (e.g., dividends attributable to foreign-source dividend and interest income or to short-term capital gains or U.S. source interest income to which the exception from withholding described above does not apply) are generally subject to withholding of U.S. federal income tax at a rate of 30% (or lower applicable treaty rate).
  •   A decline in the adoption of bitcoin could have a negative effect on the price of bitcoin and bitcoin-related investments. Bitcoin’s adoption has been on a generally continuous climb since bitcoin first gained mass media attention in 2013. However, there can be no guarantees this growth will continue. Further, adoption of bitcoin as a means of payment has been limited when compared with the increase in the price of bitcoin, indicating that the majority of bitcoin’s use is for investment and speculative purposes. A lack of acceptance of bitcoin as a means of payment could negatively impact the price of the Bitcoin Futures contracts in which the Fund invests.

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).


As bitcoin and other digital assets have grown in popularity and in market size, certain U.S. federal and state governments, foreign governments and self-regulatory agencies have begun to examine the operations of bitcoin, digital assets, the Bitcoin Network, bitcoin users, Bitcoin Exchanges and the Bitcoin Exchange Market. These regulatory efforts include, but are not limited to, the following.
When rolling futures contracts that are in contango, the Short Bitcoin Fund may buy the expiring bitcoin futures contract at a lower price and sell a longer-dated bitcoin futures contract at a higher price, resulting in a positive roll yield (i.e., a gain). When rolling futures contracts that are in backwardation, the Short Bitcoin Fund may buy the expiring bitcoin futures contract at a higher price and sell the longer-dated bitcoin futures contract at a lower price, resulting in a negative roll yield (i.e., a loss).
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.
This mega-powerful currency has not only opened the gate for other currencies, but also leads the cryptocurrency world with pride. It is governed to make sure no extra Bitcoin is produced, as a maximum quantity of 21 Million Bitcoin units was agreed to. When introduced, the rate was $1 to 1,309 BTC. The wheel has turned, and when Bitcoin reached the all-time high of $19,783.21 in 2017, it was certainly a meaningful milestone for Satoshi Nakamoto, the creator of Bitcoin.
Each of the Managed Futures Strategy ETF, the Crude Oil Strategy ETF, the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF (each, a “Parent Fund”) intends to achieve commodity exposure through investment in the ProShares Cayman Portfolio I, the ProShares Cayman Crude Oil Portfolio, the ProShares Cayman Bitcoin Futures Strategy Portfolio the ProShares Cayman Short Bitcoin Futures Strategy Portfolio, the ProShares Cayman Bitcoin Futures/Equity Strategy Portfolio and the ProShares Cayman Bitcoin/Blockchain Strategy Portfolio respectively, each a wholly-owned subsidiary of its respective Parent Fund (each, a “Subsidiary”) organized under the laws of the Cayman Islands. Each Parent Fund’s investment in its respective Subsidiary is intended to provide such Parent Fund with exposure to commodity and financial markets in accordance with applicable rules and regulations. Each Subsidiary may invest in derivatives, including futures, forwards, option and swap contracts, notes and other investments intended to serve as margin or collateral or otherwise support the Subsidiary’s derivatives positions. Neither Subsidiary is registered under the 1940 Act, and neither Subsidiary will have all of the protections offered to investors in RICs. The Board, however, has oversight responsibility for the investment activities of each Parent Fund, including its investment in its respective Subsidiary, and the Parent Fund’s role as the sole shareholder of the Subsidiary.
As discussed above in “Investment in a Subsidiary”, each of the Managed Futures Strategy ETF, the Crude Oil Strategy ETF the Bitcoin Futures Strategy ETF, the Short Bitcoin Futures Strategy ETF, the Blockchain/Bitcoin Strategy ETF, and the Bitcoin Futures/Equity Strategy ETF (each, a “Parent Fund”) intends to achieve commodity exposure through investment in a wholly-owned foreign subsidiary (each a “Subsidiary”). Each Subsidiary is classified as a corporation and is treated as a “controlled foreign corporation” (“CFC”) for U.S. federal income tax purposes. Each Parent Fund will limit its investments in its Subsidiary in the aggregate to 25% of the Parent Fund’s total assets. Each Parent Fund does not expect that income from its investment in its Subsidiary will be eligible to be treated as qualified dividend income or that distributions from its Subsidiary will be eligible for the corporate dividends-received deduction.
Here’s what’s Lisk all about: Most developers today rely on centralized giants, such as Google Play and the AppStore to put up their newly developed apps. These giants take much of the profits and attention from these apps, and Lisk believes all this should be going to the developers themselves. This is where its Javascript-based tech comes in. Lisk is incredibly exciting because it aims to offer a decentralized apps platform, one that actually favors the developers, and therefore gives them the bigger piece of the cake. Lisk was previously Crypti, and after proving itself on a community level, it was forked by Max Kordek and Oliver Beddows into Lisk, in 2016.
The Trust reserves the absolute right to reject a purchase order transmitted to it by the Distributor in respect of any Fund if (a) the purchaser or group of purchasers, upon obtaining the Shares ordered, would own 80% or more of the currently outstanding Shares of any Fund; (b) the Deposit Securities delivered are not as specified by ProShare Advisors and ProShare Advisors has not consented to acceptance of an in-kind deposit that varies from the designated Deposit Securities; (c) acceptance of the purchase transaction order would have certain adverse tax consequences to the Fund; (d) the acceptance of the purchase transaction order would, in the opinion of counsel, be unlawful; (e) the acceptance of the purchase order transaction would otherwise, in the discretion of the Trust or ProShare Advisors, have an adverse effect on the Trust or the rights of beneficial owners; (f) the value of a Cash Purchase Amount, or the value of the Balancing Amount to accompany an in-kind deposit, exceeds a purchase authorization limit extended to an Authorized Participant by the Custodian and the Authorized Participant has not deposited an amount in excess of such purchase authorization with the Custodian prior to the relevant cut-off time for the Fund on the transmittal date; or (g) in the event that circumstances outside the control of the Trust, the Distributor and ProShare Advisors make it impractical to process purchase orders. The Trust shall notify a prospective purchaser of its rejection of the order of such person. The Trust and the Distributor are under no duty, however, to give notification of any defects or irregularities in the delivery of purchase transaction orders nor shall either of them incur any liability for the failure to give any such notification.
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.
