What happens to your Bitcoin if you get hit by a bus tomorrow, and could your family actually access it, or would it be lost forever?Mike, product manager at Guardblock, joins Honest Money to tackle the hardest problems in Bitcoin self-custody: backups, inheritance, and staying secure in a world where AI is making attacks more sophisticated by the day. In the wake of the Coldcard hack, Mike explains why a single device is no longer good enough, how collaborative security using multisig and Bitcoin timelocks works, and how to make sure your coins reach your heirs without leaving a dangerous security hole.🎙️ EPISODE SUMMARYMike and Anja discuss self-custody, collaborative security, and Bitcoin inheritance.The conversation moves from the lessons of the Coldcard hack and recent data breaches, through the difference between custodial and non-custodial, single-sig and multisig, to how Guardblock's time-locked vaults add a co-signing key and recovery pathways without taking custody of your coins. Mike explains why self-custody still demands personal responsibility, how timelocks let you exit unilaterally if the company disappears, and why inheritance is the single biggest reason people are signing up.The episode also covers wills and letters of wishes, the privacy and trust trade-offs of collaborative security, which hardware wallets work with Taproot miniscript, the product's pricing, and why everyday people shouldn't need to be technical experts to keep their Bitcoin safe.🔑 KEY TAKEAWAYSAfter the Coldcard hack, a single device and basic setup is no longer enoughAI tools are making attacks on Bitcoin self-custody more sophisticatedMultisig removes the single point of failure that sinks single-sig setupsCollaborative security adds a co-signing key so a stolen seed alone can't move fundsBitcoin timelocks create recovery pathways and let you exit if a provider disappearsInheritance is the biggest gap in self-custody, and the top reason people sign upPut a plan in a letter of wishes, never seed words or pins in your willEveryday people shouldn't need extreme technical skill to hold Bitcoin safely⏱️ CHAPTERS00:00 Meet Mike From Guardblock01:17 What the Coldcard Hack Taught Us06:15 Why One Device Is No Longer Enough10:01 Custodial vs Non-Custodial, Explained12:05 Single-Sig vs Multisig, Explained15:38 What Guardblock Actually Is18:45 How Collaborative Security Works24:11 How Bitcoin Timelocks Work26:40 The Recovery Pathways Explained37:00 The Privacy and Trust Trade-Offs40:26 The Bitcoin Inheritance Problem45:26 Probate, Wills, and Letters of Wishes48:47 Which Hardware Wallets Work01:03:00 Pricing and No Lock-Ins🔗 FEATURED LINKSGuardblock: https://guardblock.comGuardblock on X: https://x.com/GuardBlock21🔗 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?
