Jake Ostrovskis, trader at UK-based crypto firm Wintermute, is anticipating the upcoming launch of options on BlackRock's spot bitcoin ETF, a new product he believes could attract more U.S. retail money after its approval by the Securities and Exchange Commission last month. Because regulators view bitcoin as a commodity, though, such options may also need the green light from the Commodity Futures Trading Commission, which oversees commodity derivatives, said Youwei Yang, chief economist at BIT Mining.
