That i concur.. Though to put a microscope on it, he further states that "all the other coins are crap".. So of course i was very curious to see what coins in his opinion "are not crap".
Anyways John McAfee has been known to be visionary and eccentric (which is always a good sign in a visionary person). He basically steered a big company away from their original business model into becoming a mining farm. Plus he is already a billionaire so i think it's highly unlikely that he is in it for the money (though the possibility is not 0%)..
