The Board oversight of the Trust and the Funds extends to the Trust’s risk management processes. The Board and its Audit Committee consider risk management issues as part of their responsibilities throughout the year at regular and special meetings. The Advisor and other service providers prepare regular reports for Board and Audit Committee meetings that address a variety of risk-related matters, and the Board as a whole or the Audit Committee may also receive special written reports or presentations on a variety of risk issues at the request of the Board or the Audit Committee. For example, the portfolio managers of the Funds meet regularly with the Board to discuss portfolio performance, including investment risk, counterparty risk and the impact on the Funds of investments in particular securities or derivatives. As noted above, given the relatively small size of the Board, the Board determined it is not necessary to adopt a complex leadership structure in order for the Board to effectively exercise its risk oversight function.

Inverse bitcoin contracts are usually denominated in USD terms. So if there's a contract value of $100 then each side -- LONG and SHORT -- puts down some portion of the contract value in margin. The contract is an agreement between traders to pay the other side an amount of bitcoin profit/loss as the price changes. Each contract has an expiration date, and some exchanges have periodic (daily or weekly) dates where the contract period's profits are "settled" even if the contract has not expired.

Bitcoin and other cryptocurrencies have evolved from a playful experiment among technical experts to an established and growing branch of the global financial industry.
