Bloomberg analyst Elliott Stein predicts a 70% chance of full dismissal for Coinbase in its ongoing lawsuit against the US Securities and Exchange Commission (SEC). Stein's confidence shifted after a recent five-hour hearing, where Coinbase provided a more precise definition of an "investment contract" compared to the SEC. The SEC alleges that Coinbase is engaging in the offer and sale of investment contracts, falling under SEC regulation, and operating as an unregistered broker without adequate licenses. However, Stein believes the recent Ripple v SEC case, where XRP was not considered a security, may impact Coinbase's lawsuit.
