I don't beleive in some theories presented here saying that governments are actualy contoling Bitcoin by buying large amount in th beginig with the aim to destroy Bitcoin. This is just another conspiracy theory. And Bitcoin is not that relevant to governments as some might think and they don't consider it as such big threath, they have biger issues. But it's true that recently governments are more interested in Bitcoin than before because they see their opportunity to have their peace of cake.
