I want to add the other problem of offline wallets getting lost/stolen/destroyed which results in funds being permanently lost/stuck. Is there any solution to this yet? If I die my estate can be dished out to family members via estate laws and the banks comply with it.. how does one liquidate cryptocurrencies when I die? My family will most likely not be protected in that case and the funds will be stuck forever.
