This issue has been discussed before, and I have considered it before. If something happens to me, what should I do with these assets? I have now taught my family and friends to use cryptocurrency and told them to store my keys correctly. When my misfortune does happen, they can access it based on the key I provided. Of course, if it can be written in the will, there are legal advantages. But if we don’t have time to tell our family and friends, when we die, our assets will be lost, and the family will lose a piece of protection.
are you going to include the keys to the will? surely if that's a big amount of money if someone sees it, they would have got interested and stole it,
the most convenient way would give it to a person you trusted inside the family, I would not entrust it to someone outside of the family, but if it happens that if you died and you never tell it to someone, that money will stay there because it will be impossible for them to crack it open without the keys.
Yes, this method of yours is also possible. It is best to tell your family that if you are friends, you will inevitably have other ideas. But if it is written on the will, it can be placed in a safe, after all, wealth must be kept carefully.
