Hey I just listened to the interview, and you seem to have the exact same concerns that I have had. Thanks for sharing that! I listened to the first video you sent, but the second video says it’s private.

I wish you would have known about BTCapsule a few weeks ago 😂

BTCapsule does not require multisig or any third parties, so it is completely private. You create the transactions offline, give the inheritor their wallet, and nobody has to know this ever happened. If you change your mind or need your Bitcoin for any reason, you simply broadcast your own transaction and sweep the paper wallet into your own wallet. Otherwise, the Bitcoin will sit on the P2SH address until your inheritor broadcasts their transaction on the date you chose.

I think BTCapsule is exactly what you were looking for. Would love to know your thoughts about it.
