According to Bloomberg ETF analyst Eric Balchunas, the U.S. Securities and Exchange Commission (SEC) has published general listing standards for crypto asset ETPs through exchange filings. As long as a crypto asset has more than 6 months of futures trading history on the Coinbase Derivatives Exchange, it will meet the listing requirements, which is expected to cover more than a dozen mainstream currencies, and could be approved as early as September to October.
