I read his Forbes article and all this man is doing is trying to say the whole Bitcoin community is a bunch of scam artist trying to suck money out of those less informed about it. In time I believe that we will see him either change his tune on Bitcoin or it will come out that he has invested in Bitcoin, most of these attacks on Bitcoin are used to drive the price down so people can get into the game at a lower price point and then when the money starts rolling in say see I told you this was a great investment. So i would take anything he says with a grain of salt and regard it as someone that really has no clue about what they are talking about.
