Taking their prices from bitcoin futures, the swaps will not handle bitcoin directly. Seeing as Morgan Stanley is a regulated and established financial institution, tying the product to futures contracts is a safer bet than basing them on bitcoin’s spot price, as the Chicago Mercantile Exchange and Chicago Board of Exchange offer fully-regulated bitcoin futures from which Morgan Stanley can pool pricing data.
Interest Rate Risk — The Fund intends to invest a substantial portion of its assets in U.S. Treasury securities and is subject to interest rate risk. Interest rate risk is the risk that debt securities may fluctuate in value due to changes in interest rates. Commonly, investments subject to interest rate risk will decrease in value when interest rates rise and increase in value when interest rates decline. The value of securities with longer maturities may fluctuate more in response to interest rate changes than securities with shorter maturities. A wide variety of factors can cause interest rates to rise (e.g., central bank monetary
Given the economic and environmental concerns associated with mining, various "minerless" cryptocurrencies are undergoing active development.[40][41] Unlike conventional blockchains, some directed acyclic graph cryptocurrencies utilise a pay-it-forward system, whereby each account performs minimally heavy computations on two previous transactions to verify. Other cryptocurrencies like Nano utilise a block-lattice structure whereby each individual account has its own blockchain. With each account controlling its own transactions, no traditional proof-of-work mining is required, allowing for feeless, instantaneous transactions.[42][better source needed]

The promoters of these products promise traders a way to beat the market by arbitraging prices between different exchanges. Don’t believe the hype. Bitcoin exchanges often have expensive withdrawal processes and hefty fees for trading bitcoin with fiat currencies, such as dollars or euros. Also, settlement of bitcoin trades can take hours. These factors will eliminate any profits from bitcoin arbitrage and may even lead to losses.
 	•	 	Changes in the Bitcoin Network could have an adverse effect on the operation and value of bitcoin, which could have an adverse effect on the value of Bitcoin Futures Contracts and the value of Fund Shares. The open source nature of the Bitcoin protocol permits any developer to review the underlying code and suggest changes to it via “Bitcoin Improvement Proposals”, or “BIPs.” If accepted by a sufficient number of miners, BIPs may result in substantial changes to the Bitcoin Network, including changes that result in “forks.” Such changes may influence 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.

•   Investments by a Fund in options, futures, forward contracts, swap agreements and other derivative financial instruments are subject to numerous special and complex tax rules. These rules could affect the amount, timing or character of the distributions to shareholders by a Fund. In addition, because the application of these rules may be uncertain under current law, an adverse determination or future Internal Revenue Service guidance with respect to these rules may affect whether a Fund has made sufficient distributions, and otherwise satisfied the relevant requirements, to maintain its qualification as a regulated investment company and avoid fund-level tax.
Let’s say Larry owns one bitcoin and the current price is $16,600, be believes the price is overdone to the upside for a short period of time.  This is a fictional example, so don’t beat me up on the outlook, you can criticize Larry, but he’s made up too.  Larry has a futures account and sees that he can sell short a January XBT Future at $17,600.  He decides to do this and is now short 1 January XBT Future at $17,600. 

Now, what if the Bitcoin price is rising? For example, if 1 BTC is worth 5,500 USD, you don’t want to fulfill this contract any more and sell cheap for 5,000 USD. In order to still make things fair for both participants, the exchange (here CME) will make sure that you can sell for the current market price of 5,500 USD if you so wish, but they will compensate your contract partner for this. How? They will take the difference – 500 USD – out of your so-called margin account and give it to Mortimer. This kind of settlement is not only performed on the fulfilment date of the futures contract, but on every trading day, according to the current price of the asset.

Orders to redeem Creation Units outside the Clearing Process (other than for Global Fund orders), including all cash-only redemptions, must be delivered through a DTC Participant that has executed the Authorized Participant Agreement. A DTC Participant who wishes to place an order for redemption of Creation Units to be effected outside the Clearing Process need not be a “participating party” under the Authorized Participant Agreement, but such orders must state that the DTC Participant is not using the Clearing Process and that the redemption of Creation Units will instead be effected through a transfer of Shares directly through DTC. A redemption order for a Fund must be received by the cut-off times set forth in “Redemption Cut-Off Times” above. The order must be accompanied or preceded by the requisite number of Shares of Funds specified in such order, which delivery must be made through DTC to the Custodian by the second Business Day (T+3) following such transmittal date. All other procedures set forth in the Authorized Participant Agreement must be properly followed in order to receive the next determined NAV.

•   ETN Risk — The Fund is likely to obtain substantial exposure to the price movements of bitcoin by holding ETNs that provide exposure to the price of bitcoin. ETNs are unsecured, unsubordinated debt securities of an issuer that are listed and traded on a U.S. stock exchange. An ETN’s returns are generally linked to the performance of a particular market benchmark or strategy minus applicable fees. ETNs do not provide principal protection and may or may not make periodic coupon payments. ETNs are subject to credit risk, which is the risk that the issuer cannot pay interest or repay principal when it is due. Additionally, the value of an ETN may be influenced by time to maturity, level of supply and demand, volatility and lack of liquidity in the underlying market (e.g., the commodities market), changes in interest rates or the issuer’s credit rating, and other economic, legal, political or geographic events. The value of an investment in an ETN may be impacted by fees associated with the ETN. Structural aspects of the ETNs may impact their market value. Trading by affiliates of an ETN sponsor may create conflicts of interest. The issuer of an ETN may be unable to meet its obligations. The potential impact of Bitcoin Network forks on the value of a bitcoin ETN is unclear. ETNs issued by special purpose vehicles may include greater risk. ETNs are subject to risks associated with the underlying asset.
The Custodian is responsible for safeguarding the Funds’ cash and securities, receiving and delivering securities, collecting the Funds’ interest and dividends, and performing certain administrative duties, all as directed by authorized persons. The Custodian is also responsible for the appointment and oversight of any sub-custodian banks and for providing reports regarding such sub-custodian banks and clearing agencies.
Traders A and B in the previous example are hedgers. However, futures contracts, once they exist, can also be bought and sold in their own right. This is where futures get interesting for speculators. Say that Speculator X believes the price of a ton of pork belly will rise to 1,200 USD in 3 months’ time, so buying the futures contract at 1,000 USD is a good deal. He can then sell the contract to bacon producers who want to buy pork bellies at 1,000 USD. The option to buy at a specified price in the future is known as a call option. The price of call options rise when traders assume that the price of the underlying asset will rise.
