FTX bankruptcy causes turbulence in the cryptocurrency market, with Bitcoin dropping to $89,320, a daily decline of 3.3%. The U.S. SEC and CFTC are intensifying investigations, and there are calls within the industry for stricter regulations. Meanwhile, Ethereum founder Vitalik Buterin announced a major upgrade of 'Ethereum 2.0' to be launched in December, aiming to enhance scalability and security, which is expected to significantly improve network performance. This change may restore confidence in the crypto market and alleviate current downward pressure. Investors should pay attention to regulatory developments and technological upgrades, and must not overlook risk management.
