I think it's pretty clear that most crypto currencies a Ponzi schemes. But... There's enough demand for an international unregulated currency that I think it'll be around for awhile. There are plenty of people that tolerate its flaws. (Specifically, the volatile value.) I personally think once the scammers and "true believers" move on, Bitcoin will stay around until some other international "unregulated" internet money comes around.
