Episode notes
Bitcoin news and bitcoin analysis update. Today I cover the reported Coldcard wallet sweeps, the firmware 4.x entropy failure blamed for predictable seed generation, CoinKite’s response, emergency wallet migration, phishing attacks, and the volunteers helping affected users protect their bitcoin. I also look at how AI-assisted code review could change security standards for Bitcoin technology, hardware wallets, and open-source software far beyond Bitcoin.

- Why I recommended Coldcard and why I was wrong
- Reported Coldcard wallet sweeps beginning July 30

- BTC Sessions, Rob Hamilton, and volunteer rescue efforts
- AI code audits and the new security standard
- What this crisis means for Bitcoin self-custody
