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.

Most swap agreements entered into by a Fund (but generally not CDS) calculate and settle the obligations of the parties to the agreement on a “net basis” with a single payment. Consequently, a Fund’s current obligations (or rights) under a swap agreement will generally be equal only to the net amount to be paid or received under the agreement based on the relative values of the positions held by each party to the agreement (the “net amount”). Other swap agreements, such as CDS, may require initial premium (discount) payments as well as periodic payments (receipts) related to the interest leg of the swap or to the default of the reference entity.

The rules regarding the extent to which such subpart F inclusions will be treated as “qualifying income” for purposes of the 90% gross income requirement described above are unclear and currently under consideration. In the absence of further guidance, each Parent Fund will seek to ensure that it satisfies the 90% gross income requirement, including but not limited to by ensuring that its Subsidiary timely distributes to it an amount equal to the Subsidiary’s subpart F income by the end of the Subsidiary’s taxable year. In order to make such distributions, the Subsidiary may be required to sell investments, including at a time when it may be disadvantageous to do so. If a Parent Fund were to fail to qualify as a RIC accorded special tax treatment in any taxable year, it would be subject to tax on its taxable income at corporate rates, and all distributions from earnings and profits, including any distributions of net tax-exempt income and net long-term capital gains, would be taxable to shareholders as ordinary income. In addition, the Parent Fund could be required to pay substantial taxes, penalties and interest, and to make substantial distributions, in order to re-qualify for such special treatment.

  8. Except for the Managed Futures Strategy ETF, the Crude Oil Strategy ETF and the CDS Short North American HY Credit ETF, concentrate (i.e., hold more than 25% of its assets in the stocks of a single industry or group of industries) its investments in issuers of one or more particular industries, except that a Fund will concentrate to approximately the same extent that its index concentrates in the stocks of such particular industry or industries.

For purposes of determining whether the Funds are concentrated in an industry or group of industries, each Fund may concentrate its investment in the securities of companies engaged in a single industry or group of industries to approximately the same extent as its benchmark and in accordance with its investment objective and policies as disclosed in the Prospectus and SAI.
XBT futures is a cash-settled contract that settles to a single, tradeable auction price. In designing XBT futures, Cboe leveraged its significant product development expertise to design an instrument that allows participants to implement trading strategies in a manner to which they are accustomed.

If you round the BTC you bought with start capital down, you will have slight overexposure LONG with the left-over BTC. If you round up and short an extra contract, you will have slight overexposure SHORT.
