594.48 BTC Worth About $38M Swept From 500 Wallets After Coldcard Seed Entropy Warning

More than $38 million in Bitcoin or 594.48 BTC was moved from about 500 wallets into a single bc1qnk address in a short burst, according to Lookonchain. Coinkite said a firmware bug could reduce seed entropy on Coldcard Mk3, Mk4, Mk5, and Q, and warned that updating firmware does not fix existing seeds, requiring a new seed and fund migration.
