And it could also be a way for them (or those that control them) to bring in a cashless society and a one world currency. I saw an article today on Sky News about bitcoin suggesting it was a way of "fighting governments and banks". A sure sign that they are behind it IMO (a bit like wikileaks (I mean if he was giving away classified information why tell people where to find it?)).

Whether their behind it or not I think it's a mistake not to be in it.
