Several factors may affect a Fund’s ability to achieve a high degree of correlation with its benchmark. Among these factors are: (i) a Fund’s fees and expenses, including brokerage (which may be increased by high portfolio turnover) and the costs associated with the use of derivatives; (ii) less than all of the securities underlying a Fund’s benchmark being held by the Fund and/or securities not included in its benchmark being held by a Fund; (iii) an imperfect correlation between the performance of instruments held by a Fund, such as futures contracts, and the performance of the underlying securities in a benchmark; (iv) bid-ask spreads (the effect of which may be increased by portfolio turnover); (v) holding instruments traded in a market that has become illiquid or disrupted; (vi) a Fund’s share prices being rounded to the nearest cent; (vii) changes to the benchmark that are not disseminated in advance; (viii) the need to conform a Fund’s portfolio holdings to comply with investment restrictions or policies or regulatory or tax law requirements;

Simply, the OBV is a remarkable technical indicator that can show us if the real money is really buying Bitcoin or quite the contrary they are selling. What we want to see when Bitcoin is failing to break above a resistance level or a swing high and the Ethereum already broke is for the OBV to not only increase in the direction of the trend, but to also move beyond the level it was when Bitcoin was trading previously at this resistance level (see figure below). Here is how to identify the right swing to boost your profit.

The term altcoin has various similar definitions. Stephanie Yang of The Wall Street Journal defined altcoins as "alternative digital currencies,"[25] while Paul Vigna, also of The Wall Street Journal, described altcoins as alternative versions of bitcoin.[26] Aaron Hankins of the MarketWatch refers to any cryptocurrencies other than bitcoin as altcoins.[27]


The Fund may invest in stocks of large-cap companies. Although returns on investments in large-cap companies are often perceived as being less volatile than the returns of companies with smaller market capitalizations, the return on large-cap securities could trail the returns on investments in smaller and mid-sized companies for a number of reasons. For example, large-cap companies may be unable to respond quickly to new competitive challenges, such as changes in technology, and also may not be able to attain the high growth rate of successful smaller companies.
The right of redemption may be suspended or the date of payment postponed with respect to any Fund (1) for any period during which the Exchange is closed (other than customary weekend and holiday closings); (2) for any period during which trading on the Exchange is suspended or restricted; (3) for any period during which an emergency exists as a result of which disposal of the shares of the Fund’s portfolio securities or determination of its NAV is not reasonably practicable; (4) in such other circumstance as is permitted by the SEC; or (5) for up to 14 calendar days for any of the Global Funds or Short or Ultra International ProShares Funds during an international local holiday, as described below in “Other Information”.
Currently the front month future is the January contract which at last check could be sold for $17,600.  This contract settles in a cash transfer based on the 4:00 pm eastern bitcoin auction price on Wednesday January 17, 2018 established by Gemini who is partnering with Cboe Global Markets.  The bitcoin price at Gemini is close to $16,600 so I will use that for the underlying bitcoin price in this example. 
Each Fund may consider changing its index at any time, including if, for example: the current index becomes unavailable; the Board believes that the current index no longer serves the investment needs of a majority of shareholders or that another index may better serve their needs; or the financial or economic environment makes it difficult for the Fund’s investment results to correspond sufficiently to its current index. If believed appropriate, a Fund may specify an index for itself that is “leveraged” or proprietary. There can be no assurance that a Fund will achieve its objective.
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.
In this guide we don't want to deal with social loss risk, so use the FCA-regulated, London-based bitcoin derivatives exchange CryptoFacilities. They offer contracts with 2% margin requirement (50x leverage) as well as a 15% margin requirement (6.5x leverage). They are 100% bitcoin based, but they don't accept US customers.
