I think the government's ban on bitcoins in their countries is something BAD, bitcoin can bring to countries that have not developed some of the projected wages they can make, but that's the economy. Developed as strong as Japan and America.
It would be good for government to accept bitcoin other wise they're wasting there time to stop bitcoins.They can include some taxes on bitcoin but they can't stop it nor they can trace our transaction and control its price.
Yeah, it is bad if government ban the bitcoin in its country, it is bad for government and also for its people, because bitcoin or other crypto currency people have a chance to earn money and if government not allow to its people then government do bad with its citizens. Everyone has the right to use all the technologies and government should realize that the next era will be of digital currency. So its better to regulate bitcoin in the countries rather than thinking of banning it.
