The U.S. Securities and Exchange Commission has all but made clear it will probably approve Bitcoin exchange-traded funds that hold Bitcoin futures, versus ones that hold the cryptocurrency itself. This has sparked a wave of new filings which, if approved, could hit the market by November. But how do they work, and how will investors respond to them?

On this week's Trillions, we get insight into this from two people who currently offer Bitcoin futures funds, Simeon Hyman of ProShares, who runs a Bitcoin futures mutual fund, and Steve Hawkins of Horizons, who runs a Bitcoin futures ETF in Canada. They discuss how the futures market works, how performance differs from Bitcoin, roll costs and what a wave of these hitting the market just might look like.
