<p>🎯 EPISODE THESIS </p>

<p>━━━━━━━━━━━━━━━━━━━━━━━━━━ </p>

<p>"Not your keys, not your coins" only protects you if the keys were actually random in the first place.</p>

<p>This week, Coinkite disclosed that certain Coldcard devices generated recovery phrases with weakened randomness — and updating the firmware doesn't fix a seed that's already out there. Coinkite's founder NVK called it "heartbroken" territory in a public apology, and committed to full transparency on how it happened.</p>

<p>In this episode, I break down exactly what went wrong in the code, why it slipped past review for years, and — most importantly — the exact steps to check if you're affected and migrate your funds safely.</p>

<p>This is the episode you send to anyone you know holding a Coldcard, especially if they're not glued to crypto Twitter. Every hour matters.</p>
