Odaily Planet Daily News Nasdaq sent a letter to the U.S. Securities and Exchange Commission (SEC) cryptocurrency team, suggesting that U.S. cryptocurrency regulation should establish a clear digital asset classification law to help define four major categories of digital assets. Nasdaq believes that precise classification will help determine which agencies are responsible for supervision, and pointed out that securities assets should be regulated by the SEC and commodity assets by the Commodity Futures Trading Commission (CFTC). Nasdaq also suggested that the two regulators should develop platform trading rules applicable to multiple digital asset categories. (CoinDesk)
