Currently, the only Bitcoin ETF approved by the U.S. Securities and Exchange Commission (SEC) is the ProShares Bitcoin Strategy ETF (BITO), launched in late 2021 with a 0.95% expense ratio. Note that there are no Bitcoin ETFs presently approved that hold bitcoin. Instead, the ProShares ETF tracks Bitcoin futures contracts that trade on the Chicago Mercantile Exchange (CME). Nevertheless, the SEC is currently reviewing several applications for various Bitcoin and crypto ETFs, and other countries, such as Australia, have approved Bitcoin ETFs that do track Bitcoin directly.
