Griff Green, a member of the Arbitrum Security Council, has criticized Circle for its lack of action against hacker threats, contrasting it with Tether's proactive measures. Green claims that Tether actively freezes funds linked to hackers, aligning with early crypto principles, while Circle, backed by Goldman Sachs, prioritizes profitability over security. He suggests that the crypto community might consider selling off USDC to pressure Circle into taking more decisive action against such threats.
