Why all this talk about taking it down.  The reality is that it's already been shown not to be so good at covert drug dealing and the only thing left is speculation.  As long as governments get their tax cut they just don't care.  They got the printing press and taxes.  They will gladly support 100 winkelvoss / bitcoin trust etfs and as many exchanges as want to register and track users.  Sure there will be wealth made but real change takes time and mass populace discontent and we just aren't anywhere near that.  Enjoy the riches and be quick on the sell trigger if and when your stash becomes fuck you money.
