I have two people I can trust with money, even though it's not completely. Other than that, I don't trust any other person. It's not an ideal way to live, but it gets me through. I don't like it, I like trusting people close to me, but I don't have a choice because I'd be a fool to do that. I haven't really looked into it because I don't have that many assets yet, but I believe there are ways to make sure your asset gets passed to the right people in case of your death.
The problem I have is that the people I trust don't live close to me and they don't have any idea about how what I do works so I cant even rely on them to do things right if any thing happens to me.
If you want to leave something after your death but don't want to get robbed while being alive you have to diversify your investments into assets like real estate or gold.
Cryptocurrency was meant to be used more casually and can be seen as an investment but for sure it has too many problems to use it as a decrease.
There are just too many better, safer options for that.
