Galaxy Research is tracking the Coldcard hack in real time. They've identified three waves of sweeps so far: 1,367 BTC (~$88.6M) drained from 4,585 addresses. The first wave hit 1,196 addresses in a 41-minute window, all paying an identical 30 sat/vB fee. Automated key scanning, not owners moving funds. Galaxy notes "the loss profile is dominated by sub-1 BTC addresses in count, but by larger addresses in value. This appears to be the shape of individual self-custody, not institutional holdings." Not one coin taken was created before the vulnerable firmware shipped in March 2021.
