Chris Seedor of Seedor & Bitsurance joins us to talk about the rising threat of physical "wrench attacks" and advanced Bitcoin self-custody. We discuss the 70% spike in violence against BTC owners, using Miniscript for time-locked security, and how AI-driven phishing is bypassing video IDs. Chris explains why simple seed phrases are high-risk and how protocol changes like covenants could revolutionize reactive security for all holders.
