Okay so that time lock mechanism is dope and I'd love to do that. Multi sig wallet is great to pair with that as well and making a wallet for your kid/s also fun. I'm probably going to make a super elaborate treasure map for my kids and they have to work together to figure it out. Maybe tell them each a different story while they're still young and keep telling them over and over and they all come together like that ending scene in thr movie thr pacifier. Idk it woild be super fun. Also pretty risky tho like whay if they just lose thr map etc lol. Probs not going to do that anyways. But it sure sounds fun dont it?!
Cool, but the most important thing is to keep things simple. Inherited Bitcoin is mostly lost due to the complexity of these treasure maps or the incompetence of the inheritors in order to successfully get the coins.
The whole strategy must be rehearsed with your inheritors multiple times, to make sure that when the time comes they will need to follow the exact same steps that they 've already followed in the rehearsals.
Essentially, the best thing with multi-sig is that you can reveal most of your plan (like the great majority of the plan) to your inheritors because there is no chance of them doing anything bad.
For example,
hypothetically, I have a 2-of-3 multi-sig vault and I have a cosigner at home and the other 2 are geographically distributed and we need to get on a plane to reach them. Simultaneously, we need to cross some physically guarded places to finally reach the safes where the cosigners are.
You can kidnap me and get on plane while I am kidnapped and then go to the secured place no.1, where we need to identify ourselves and pass from several guards with weapons in order to physically access one of the cosigners. Yes, we can do it, but would we ever do it?!
You know my whole setup (without the actual places). But you know too much info and you can't do anything to rob me.
