If this sounds confusing to you, then don't worry. In practice, these futures contracts are just like buying and selling spot market value. Just focus on the price of the contract and whether you are LONG or SHORT. If you're long and the futures price goes up, the BTC value of the contract goes up and you have bought an asset that is increasing in value.
Credit Default Swaps (“CDS”): In the case of a CDS, the agreement will reference one or more debt securities or reference entities. The protection “buyer” in a credit default contract is generally obligated to pay the protection “seller” an upfront or a periodic stream of payments over the term of the contract until a credit event, such as a default, on a reference entity has occurred. If a credit event occurs, the seller generally must pay the buyer: a) the full notional value of the swap; or b) the difference between the notional value of the defaulted reference entity and the recovery price/rate for the defaulted reference entity. CDS are designed to reflect changes in credit quality, including events of default. The CDS Short North American HY Credit ETF will normally be a “buyer” of CDS (also referred to as a buyer of protection or a seller of risk). The CDS Short North American HY Credit ETF will primarily invest in centrally cleared, index-based CDS that provide credit exposure through a single trade to a basket of reference entities. The CDS Short North American HY Credit ETF may also invest in single-name CDS. Single-name CDS provide exposure to a single reference entity and are not centrally cleared.
  •   ADRs represent the right to receive securities of foreign issuers deposited in a bank or trust company. ADRs are an alternative to purchasing the underlying securities in their national markets and currencies. Investment in ADRs has certain advantages over direct investment in the underlying foreign securities because: (i) ADRs are U.S. dollardenominated investments that are easily transferable and for which market quotations are readily available; and (ii) issuers whose securities are represented by ADRs are generally subject to auditing, accounting and financial reporting standards similar to those applied to domestic issuers.
Special rules would apply if a Fund were a qualified investment entity (“QIE”) because it is either a “U.S. real property holding corporation” (“USRPHC”) or would be a USRPHC but for the operation of certain exceptions to the definition of USRPIs described below. Very generally, a USRPHC is a domestic corporation that holds USRPIs the fair market value of which equals or exceeds 50% of the sum of the fair market values of the corporation’s USRPIs, interests in real property located outside the United States, and other trade or business assets. USRPIs generally are defined as any interest in U.S. real property and any interest (other than solely as a creditor) in a USRPHC or, very generally, an entity that has been a USRPHC in the last five years. A Fund that holds, directly or indirectly, significant interests in REITs may be a USRPHC. Interests in domestically controlled QIEs, including REITs and RICs that are QIEs, not-greater-than-10% interests in publicly traded classes of stock in REITs and not-greater-than-5% interests in publicly traded classes of stock in RICs generally are not USRPIs, but these exceptions do not apply for purposes of determining whether a Fund is a QIE.

Since you bought 68.4246 BTC, you want to short 68 BTC and lock in the USD value. You will have 0.4246 BTC left over, which will give you a slightly long bias. You can either fix this by only buying 68 BTC in step 1 or by giving yourself more short exposure by shorting 69 BTC. Remember that CryptoFacilities contracts are inverse (which allow locking in USD) and are denominated in BTC
