One of the huge problems that crypto-currencies do not think about is inheritance. Most of us wish that when we die, our stuff goes to our children. But if our stuff is locked behind secure cryptography which depends on information locked in our brains, that does not happen.<p>Unfortunately there is no way to open up ways of passing your crypto-currency to your loved ones without opening up a possible attack during your life. But this is a use case that needs to be addressed.
