A prominent Cardano advocate has urged the U.S. Securities and Exchange Commission (SEC) to approve spot ADA ETFs, following recent delays. The SEC's postponement, attributed to new rule changes and financial regulations, has sparked calls for action. The advocate highlighted Cardano's decentralized governance, robust security, and a market cap of $28.8 billion as key factors supporting ETF approval. Despite a temporary 10% dip in ADA prices due to the delay, optimism remains high among traders, with expectations of increased institutional interest and DeFi activities potentially driving future growth.
