However, there could be a transition stage in which volatility could actually become worse. Large financial trading firms could enter the market to an extent that has not been seen yet, and because bitcoin is so difficult to value (as Warren Buffet put it: “You can’t value bitcoin because it’s not a value-producing asset.”), a lot of different forces will act on its price. Shorts will become more popular, and disagreements on pricing could manifest in the cryptocurrency markets in the form of extreme price jumps, more so than is already commonplace.
But… it's also possible that the institutional investors that are negative on bitcoin's prospects (and there's no shortage of those) may use the futures markets to put money behind their conviction. It's much easier to sell a futures contract with a lower-than-market price than it is to actually short bitcoin. These investors may well send signals to the actual bitcoin market that sends prices tumbling.
• Bitcoin is available for trading 24-hours a day globally and, as such, the price of bitcoin may change dramatically when the market for bitcoin futures contracts is closed or when Fund shares are not available for trading on the Exchange. The price of bitcoin may change dramatically at times when investors are unable to buy or sell Fund shares.
