Jorge, why do I have the impression your assumptions are nothing but personal opinions and totally not fact-based? Did you ever bother to read the comments right after the link you posted? And since when a ponzi (is this even certified?) scheme is bad to take BTCs for its "service"?

Besides, from my point of view, the rise in the price could as well be because some people needed to convert to BTC for a gazillion other reasons than this one...
