On-chain activity: 594 BTC (about $38 million) was transferred out of a Coldcard wallet, and Coinkite has issued an urgent Mk3 user alert—users should migrate now.

Monitoring shows address 0x3f2a7d1e...b91c accumulated 420 ETH in the three hours before the plunge.

Data doesn’t lie—cold wallet security plus unusual fund movements. What do you think?
