I am not afraid to die.But I am afraid to the people that I will be leaving.In some point and stage of my life I have been loved,cherished by the people who loved me.So better get close with someone else.Make a family for you and your money to have purpose.It is very fulfilling seeing soneone who is beside you and caring and smiling with you.Go get a life!
I agree with this one. Since you are single, go out, explore the world, make connections and maybe you can meet someone whom you can share your life with. No one can tell whether your nephews will be interested in bitcoin in the future. That's why I think, you should have your bitcoins converted into cash and buy a one or two property or anything tangible that you can pass down to your nephews. Let's say, a educational plan, maybe. Surely they can use that once they grow up. This way, you can make sure that they will be able to use whatever you will leave them rather than just the private key.
