Coinbase, a leading cryptocurrency exchange, is facing a lawsuit from the U.S. Securities and Exchange Commission (SEC) for allegedly operating as an unregistered broker and allowing the trading of unregistered securities. The SEC's allegations include Coinbase's violation of rules through its "staking" service. This development comes after the SEC filed a similar lawsuit against Binance, the largest crypto exchange globally. Industry analysts have been anticipating such actions against Coinbase, which heavily relies on altcoin trading and staking. The outcomes of these legal battles could have significant implications for the cryptocurrency industry and reshape the regulatory landscape.
