As your investments begin to mature into a considerable amount, while you consider the security and safety of it, it is also important that you consider the situation where you die suddenly and your Bitcoin gets lost; no investor would want that except they have no family and friends worthy enough for it.
In the future, people will definitely hold Bitcoin for that, just like when you open a bank account, you must have a nominee because if the owner of the first bank account dies, his nominee or the second person will own that account. In the same way, in the case of Bitcoin holding, the family should be informed, maybe the father is holding Bitcoin for his future and to protect the future of the child, he is holding this Bitcoin. Of course, the wallet password should be left with trusted members of his family, so that if the father or Bitcoin holder dies, his family members can retrieve his Bitcoin.
Or if a young man is holding Bitcoin, then his father or any member of his family should be informed about this and the private should be left with him. The private can keep two to three copies of it on paper, it is better for the Bitcoin holder to keep this private only with him. Then the chances of losing Bitcoin holdings are very low because people's death is very close.
