Since bitcoins are not in the hands of government , many countries have banned it and are in the phase on banning bitcoins............ So what should be done? What should be said to the governements?

You should move over to the China board to see that bitcoin is flourishing there.
In fact, the largest bitcoin exchanges by volume are in China.
Well, I heard also the biggest bitcoin user in the world is china. But the question is whether the bitcoin is legal or illegal. Is there already regulation from the government or not?
