There's the fact that the Euro is in trouble. There's the fact that provable odds gambling has been implemented (a powerful factor in the US). There's the fact that ASICs are coming out. There's the fact that it's becoming countercultural and hip to accept them (see Mega and Reddit) There's the fact that every time the price goes up more mainstream articles are exposing people to it's concepts, driving demand by more. Now it could well be bubble mark II and I DEFINITELY expect a correction: it's a volatile market. But there's certainly some massive growth underneath the massive speculation.
