what if you suddenly die or fall into a coma?
Too many people rely on their own brain as if good mental health is a given. I could have a stroke in the middle of writing this particular reply and I could get a decent amount of damage out of it too. Even if the person does not die, there is a plethora of diseases they can get that could permanently alter their thoughts, memories et cetera.
After all, maybe you are mentally there. Stable and as healthy as ever. Yet, you likely have a password you never got to remember of your old accounts.
Planning to hand your Bitcoin to the next person if you enter a coma, forget or die is a very complex subject. Who do you hand it over to? What if they are only apparently trust worthy? What if THEY go absolutely crazy within an year and decide to hurt you for your Bitcoin?
What if they are trust worthy but their spouse is not or is only apparently so?
It is easy, very easy for people to imagine you have a lot of money simply because you stated you own Bitcoin. If you are telling them about it because you want to explain to them how to access it in the tragic event of your death, it is even easier to assume there is a lot of money in there that you are trying to protect. Because obviously, no body would be frantic about protecting their iPhone or iPad in case of their death, even if it is a device worth over 1000 Dollars.
This is why it is not that easy to protect your Bitcoin. It can be difficult to prove an eventual theft. But then, the first reason is probably that we are lazy as human beings and we are naive enough to not understand that we all owe a death at the end of our lives, and the end of our lives can be simply any given moment. Dying before you actually do something about your Bitcoin, good luck to the people who inherit your wealth at unlocking your Bitcoin Wallet given they likely have no experience with it.
