When I die, before that happens I will teach my children to manage my bitcoin. And I've done that to the right to continue my bitcoin that has been running.
When you die and can not leave any small sample of inheritance or a private place to find, the value for money will be hashed forever. And that would be the fact that in the next cycle when mining is no longer appropriate. 21 million bitcoin can be left only 15 million. 
For me if i die, my husband will take over my bitcoin. Because he is the one who introduce me how bitcoin works. And probably our children will be soon to become a bitcoiners. My children know about bitcoin but they don't know yet the process. I'll wait a little time to teach them how.
