Does anyone know of a guide that allows you to leave your cryptocurrencies to your family in the event of your death?
There are multiple issues that I see with all the ideas that I had, but the following is the best setup I could come up with until now:
Leave the private key to your lawyer. This would seem the most obvious route, because the lawyer already has access to your estate and takes care of it after your death. You can leave your private key encrypted with one lawyer and leave the passphrase to another lawyer, that don't know of each other so that after you pass away your family receives the private key and the passphrase to decrypt it. In the event of your death, the two lawyers will hand over their part of the inheritance to your family and they could decrypt the private key using the passphrase.
But how do you handle multiple wallets and addresses? I don't store all my bitcoins in one wallet or one address. I would have to leave the private keys and passphrases to every one of them and update them as time passes and I add more and more wallets and addresses.
What is your opinion on this issue? How to handle this properly and securely?
