In the rapid development progress of bitcoins, there has been countries where bitcoins are banned like China ,Bolivia ,Bangladesh and others.......... 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?

?
Well this has always been the issue of Bitcoin ever since. It is hard to track down Bitcoin transactions which makes it alarming for the government as it can be a mean of money laundering and transaction for illegal drugs.
Which is why I also undetstand the side of the government. But still, the illegal activities should not stop the development and improvement of a free world. And what they should seize are those illegal activities, because they will still those activities even without Bitcoin.
