Over the past 24 hours, security incidents in the crypto market have been concentrated. Polymarket suspended trading after a third-party service provider was compromised; multiple users reported unauthorized transfers of assets, with losses of about $800,000 in a single account, and the platform said affected users will receive full compensation. Wagyu confirmed a data breach involving records of more than 10,000 users and nearly 40,000 orders; hackers had demanded $5 million. Bithumb said the incident involved 6,444 customers, of whom 844 had personal information leaked. Bitcoin Core fixed 3 security vulnerabilities discovered by AI. On the market front, Ondo expanded its smart portfolios to Solana, and BNB Chain announced the winners of its tokenized stock hackathon. The initial estimate of US third-quarter real GDP annualized quarter-over-quarter was 3.4%, exceeding the expected 3.2%. Some traders believe Bitcoin has withstood multiple negative factors, and the market's resilience may signal bull market characteristics. Another study estimated that about 29,600 physical qubits could crack Bitcoin keys in about 1 hour.
