Most people mistakenly trust fiat currency produced by banks. The few that don’t trust government own gold and other PMs. Bitcoin, et al, is a fad for geeks and the general public will never trust it or understand it. and that is a shame because it is far superior to paper money.
Looks like a typical case of a guy who thinks he's so smart that anything he doesn't understand must also be too difficult for the general public to understand. Too bad for him he's actually an idiot.
