Here is the thing my friend, if nothing knew you have a bitcoin or an alt coins, those assets die with you too. So I could advice is to let one close friend or family member to knew your possessions and give them instruction in the case those unwanted event occurs. They, will even be happy that you left them some treasure that could be use in your memorial service. But you know, I just think of, I think those coins could be claimed by the crypto wallet service provider if they knew no one got interest on a particular account.
