Yeah that is definitely a tough situation. I guess at that point the total pool of Bitcoin that will ever be in existence shrank. Bitcoin causes so many interesting questions like this. It is definitely nice to have a third party that can handle fringe cases like this but that is what happens. Total control over your money is a double edged sword!
Just as we are condemned to be free dear, sigh.
Just like what everyone here has said, make proper estate planning. That's much more important in bitcoin than in other traditional assets where it's easy for them to be traced back to the owner (with the government more than happy to help
) So leave whatever necessary information there is for your family to be able to get your bits. On the plus side, unless they cash out, the government would probably have no idea the money changed hands (especially in countries with weak law implementation).
There can be many ways to solve this situation. You could entrust your bitcoins to your lawyer so he will release them to your family in case of your death or illness. You could also build some dead man's switch that will give your private key to your relatives. For example you could build a smart contract that would require you to enter some password once per month or per week, and if you will fail, your private keys would be released to your family.
Now that's interesting. I've always thought that it would be nice for things to be released after death but I had no idea it's already being used.
How is it done? Do you like sign-up for a service, enter a password at regular intervals and if you don't they show up outside your house?
