According to Techub News, Nasdaq has sent a lengthy letter to the U.S. Securities and Exchange Commission (SEC) crypto working group, suggesting that U.S. regulators carefully define digital assets into four categories to clearly determine which agency acts as the arbiter. Nasdaq believes that the four major categories of digital assets in the future should be: financial securities, digital asset investment contracts, digital asset commodities, and other digital assets. These categories of securities fall under the jurisdiction of the U.S. Securities and Exchange Commission (SEC), which will work with its sister agency, the Commodity Futures Trading Commission (CFTC), the latter of which will be responsible for handling these commodities.
