The SEC has once again delayed the approval of multiple spot ETFs, causing an uproar in the market. It was initially thought that this step would allow cryptocurrencies to enter the mainstream investment arena, but the SEC's cautious attitude has left investors impatient. Once these ETFs are approved, it means that more funds can legally enter the market for crypto assets like Bitcoin, presenting enormous potential. However, regulatory authorities still harbor concerns about market volatility and investor protection issues, and the decision to delay approval has pushed this 'crypto financial revolution' back another step. Should we wait for opportunities, or continue to observe? Everyone is looking forward to the final ruling.
