Coinkite's security advisory confirms firmware updates protect newly generated seeds but cannot repair seed phrases created on vulnerable versions. The advisory identifies Mk3 firmware 4.0.1 through 5.0.3, Mk4 and Mk5 firmware before 5.6.0, and Q firmware before 1.5.0Q as affected. Dogecoin community contributor Mishaboar urged all Coldcard users to migrate funds immediately to wallets controlled by newly generated seed phrases, warning against reusing affected seeds or entering recovery words into internet-connected computers — though his guidance is broader than Coinkite's version-specific advisory.
Bitcoin traded at $63,813 with 24-hour volume of $24.7 billion and a market capitalization of $1.28 trillion as of August 3, down from over $65,000 a week earlier amid relatively thin volume. Traders attributed the slide to a liquidity vacuum rather than panic selling, with about $600 million in liquidations — mostly longs — a fraction of historical capitulation events. Strategy executed its first Bitcoin sale since 2022, a modest but symbolically notable move in a thin market.
