Don't Let Your Bitcoin Be Stolen: Expert Advice on Security, Self-Custody, and More

How do you keep your Bitcoin safe when the threats come from both sophisticated hackers and criminals at your front door?

Lloyd, cryptographer and founder of Frostsnap, joins Honest Money to talk about the full picture of Bitcoin security, from multisig wallets and geographic key distribution to the physical safety measures every serious holder should think about. Drawing on his analysis of recent real world attacks, including the Coldcard exploit, Lloyd explains where hardware wallets fall short and how to design custody that holds up against both digital and physical threats.

This conversation explores why self-custody means trusting hardware and software that can be compromised, how multisig defends against home invasions, and what recent attacks reveal about verifying device integrity and entropy.

🎙️ EPISODE SUMMARY

Lloyd and Anja discuss Bitcoin security, multisig, and staying safe from both hackers and thieves.

The conversation moves from the history of physical crime against Bitcoiners, through organised crime and the wave of attacks in France, to Frostsnap's multi device approach to securing keys. Lloyd walks through his reproduction of recent real world attacks, the technical details of the Coldcard hack, and what they mean for anyone holding their own coins.

The episode also examines the best practices that come out of these attacks, the design principles that make hardware wallets safer, and the honest question of whether self-custody has become too complex for most users, and what to do about it.
