I have an older friend who is very dear to me and we discussed the likely possibility that he would die first, since he's older than me (he's in his 50s, I'm in my 30s).
But I started thinking: death is so random—what if I die first?
I don't have many belongings or money at all, but I would want him to have my Bitcoin and Ether. Even though he's not into crypto-currency, I think he could benefit from having it as a gift through death, because I think the value would rise over the years.
It got me thinking: How would I make sure the crypto cold-storage wallet gets to him, when he lives on the other side of the country? Would I just leave a note in a random paper folder that says, If I die, please mail this to XXXXX, and just hope that the person who finds it will abide my request? What about my online accounts such as Coinbase?
This is definitely something to consider, despite near-future advances in science and technology which might have people living longer and healthier lives.
