The U.S. Securities and Exchange Commission (SEC) has approved a rule change proposal to support options trading for WisdomTree Bitcoin Spot ETF (BTCW) on the Chicago Board Options Exchange (Cboe), NewsBTC reported. This approval applies to options products that use the ETF as an underlying asset, not to BTCW itself. As a result, investors will be able to employ various investment strategies, such as hedging and volatility trading, using BTCW options.
