Similarly to bitcoin what happens in the event of my dismissal since no relative knows about my investment. It doesn't really make sense if my family can't enjoy my wealth. Will it be lost or is it good to entrust someone incase I'm no longer there?
I mean, if you have some asset, it doesn't matter whether it's bitcoin, stocks, gold, you name it, and you don't tell anyone you have it and then you die, whose fault is it? You should always leave some instructions if you don't want to tell your family what you own while you're alive. Prepare a document, a will, whatever you want, explaining what you own and how to retrieve it without being scammed.
