CZ: Bitcoin's encryption is stronger than banks, the real threat of AI is phishing and fraud Zhao Changpeng (CZ), founder of Coin Security, said that everyone was worried that AI would break the cryptocurrency, but the encryption technology relied on by the Internet and banking system was actually weaker. However, he also reminded that AI does not need to crack Bitcoin's cryptography to cause damage, and the leaked data will increase phishing and social engineering attacks, and called on users to "stay SAFU" (keep assets safe).
