> This is very important. Due to strong cryptography it's safe to assume the cryptocurrencies can't be moved without the secret key. What happens if the owner of the key dies? My father asked me about this once and I had no answer. Something to really think about. One option would be to create a multi-signature wallet, where for example three keys exist, while two keys are needed for transactions. This would allow scenarios where the widow and the notary can access a wallet after the owner died. At the same time, no single party would be able to run with the money with only one key.
