Friend, you are right, but always remember that the savings of your life should always reach the person closest to you, even after you die.
Agree you should think this ahead and at the same time protect it for security purposes. This is like a will and testament but this one is kinda like giving only a flashdrive. The best thing with this is having a ledger and keep it in safe place and tell your family that open it until you die , this is the only way that they could get your bitcoin until you die , if you cant prepare of this then your bitcoin will die also and your family is struggling to find money
