I just always wonder if those billionaires still invest in btc. Do they even know btc exist?
Good question. I know it looks like it's impossible for someone still to not know about bitcoin, but I personally talk to people at least once in two weeks about bitcoin. And when I start I think this person should definitely know something because it's either a student of Economy or a person who I think aware of all modern trends. But to my surprise it is often happens that they know nothing about BTC.
I think there are only few billionaires wants to invest in bitcoin crypto currency because the other's maybe afraid due to scammers and hackers. They don't want to lose their investment because of that.
