Coinbase, the largest cryptocurrency exchange in the United States, is set to make its final pitch to dismiss the Securities and Exchange Commission's (SEC) accusations against it. The SEC has accused Coinbase of operating as an unregistered securities exchange, broker, and clearing agency. Coinbase has denied the allegations and has filed a motion to dismiss the SEC's lawsuit. In its final pitch, Coinbase is expected to argue that the tokens it trades are not securities and that it is not operating as a securities exchange, broker, or clearing agency. Coinbase is also expected to argue that the SEC's lawsuit is a violation of the Major Questions Doctrine, which limits the SEC's ability to regulate new industries without clear congressional authorization.
