•	 	Ownership of bitcoin is pseudonymous and the supply of accessible bitcoins is unknown. There is no registry showing which individuals or entities own bitcoin or the quantity of bitcoin that is owned by any particular person or entity. It is possible, that a small group of early bitcoin adopters hold a significant proportion of the bitcoin that has been thus far created. There are no regulations in place that would prevent a large holder of bitcoin from selling its bitcoins, which could depress the price of bitcoin and have an adverse effect on an investment in the Fund.

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.
Bitcoin has been on a tear this year, surging at least 1,000 percent in 2017. As the cryptocurrency gained even more attention from investors recently, the Commodity Futures Trading Commission announced on Friday that it would allow the CME and Cboe to launch bitcoin futures. The Cboe plans to launch on Dec. 10 and the CME intends to launch on Dec. 18.
In February 2014 the world's largest bitcoin exchange, Mt. Gox, declared bankruptcy. The company stated that it had lost nearly $473 million of their customers' bitcoins likely due to theft. This was equivalent to approximately 750,000 bitcoins, or about 7% of all the bitcoins in existence. The price of a bitcoin fell from a high of about $1,160 in December to under $400 in February.[85]
Other forms of swap agreements that the Funds may enter into include: interest rate caps, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates exceed a specified rate, or “cap”; interest rate floors, under which, in return for a premium, one party agrees to make payments to the other to the extent that interest rates fall below a specified level, or “floor”; and interest rate collars, under which a party sells a cap and purchases a floor or vice versa in an attempt to protect itself against interest rate movements exceeding given minimum or maximum levels.
Note that you could just keep bitcoin on CryptoFacilities waiting to make the trade so you don't have to wait to move the bitcoin you bought over. This is called see-saw arbitrage model, where you keep funds on both exchanges to avoid having to wait. This is fine, but you can't ignore that there is extra capital being used in the play, so it affects your rate of return and capital utilisation. We will not use this method, we will do a full, complete, legitimate arbitrage process.
