(hypothetically) When I die I'd like my children to have all my bitcoins. So I was thinking of writing a will to give each of them equal amount but to make it more fun I'd hide the keys from my wallet and make it a quest.
How would they find the Bitcoin in the end? This would be very hard because you can't exactly own Bitcoin without the private keys. Do you want to make it some sort of puzzle or something?
They only way that I see this working is splitting the Bitcoin, before you die, to __ (Insert number of children you have here) Bitcoin wallets. From their you could give each child some clues and hints in your will to find the password for each account. This way it is still something like a quest and you can make sure that the funds are split equally.
Maybe you could give each child a private key from a multi sig... But it will still end up with fighting and quarrels over the amount that each child gets.
But it is a good idea and it has got me thinking too...
