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 SUMMARYLloyd 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.🔗 FEATURED LINKSFrostsnap: https://frostsnap.comFrostsnap on X: https://x.com/FrostsnapTechLloyd on X: https://x.com/LLFOURN🔑 KEY TAKEAWAYSSelf-custody means trusting hardware and software that can be compromisedMultisig wallets with geographic distribution defend against home invasionsRecent attacks show why verifying device integrity and entropy mattersHardware wallets must be designed to prevent message leaks and malicious entropyPhysical and digital security have to work together to protect your BitcoinUnderstanding real world attacks is the best guide to defending against themGood design, not just good intentions, is what keeps custody secure⏱️ CHAPTERS00:00 Introduction to Bitcoin Security and Lloyd's Background01:07 Physical Safety in Bitcoin and Historical Crime Trends05:08 Organised Crime and Bitcoin Attacks in France07:47 Government Data Collection and Privacy Concerns08:42 Frostsnap's Approach to Multi Device Security12:48 Real World Bitcoin Attack Analysis and Reproduction18:13 Technical Details of the Coldcard Hack and Attack Methods24:43 Implications for Self-Custody and Hardware Wallets29:14 Lessons from Recent Attacks and Best Practices37:25 Future of Hardware Wallet Security and Design Principles43:44 Is Self-Custody Too Complex for Most Users?56:49 The Importance of Physical and Digital Security Measures🔗 AFFILIATE LINKSBuy Bitcoin in Australia With a $10 Sign Up BonusHARDBLOCK: https://hardblock.com.au/join/honestmoneyLearn to Acquire, Secure, and Manage Your BitcoinMINERACKS: https://www.mineracks.com/honestmoneyShop Signing Devices, Bitaxes, Nodes, Apparel, and MoreSHOP BITCOIN AUSTRALIA: https://shopbitcoin.com.auCollaborative Security, Inheritance Planning, and Retirement StrategiesTHE BITCOIN ADVISER: https://thebitcoinadviser.com/honest-moneyReached Terminal Bitcoin?
