I am not to sure how it should be save unless you have back up that you entrusted to your love one's before you died in unexpected day. On that you will save your earnings token and your family can use your hard work and efforteven you are not around still your responsibility is alive.
But in case that you didn't told or even have someone in your family that you trusted about your account in bitcoin then it's also your time to say goodbye with your account. It would be useless if time comes that you die and no one knows about it, your family will never benifit your hardship here in Cryptocurrency.
