Coldcard wallet vulnerability losses could reach about 2,055 BTC, or roughly $130 million
AI Market Summary
Galaxy Research estimates a Coldcard hardware-wallet seed-generation vulnerability may have enabled theft of up to ~2,055 BTC (~$130M) across multiple coordinated waves, with attacks still active. The event undermines confidence in Bitcoin self-custody and could prompt near-term security-driven flows as users migrate funds and scrutinize firmware/seed practices. With ~90% of stolen BTC reportedly unmoved, monitoring exchange freeze efforts and on-chain movements remains critical.
