Smart governments would know by now, that they can not stop bitcoin. So, they should think: If you can't beat them, join them.
Governments who adopt btc and the blockchain technology early, will have a larger share in the new economy that will overtake the world sooner or later. Japan is the best example of such a country.
On the other hand, governments who insist on fighting the change, will be left behind.
That is why the communist party in China itself is devided about wether to ban btc or support it. Same thing is happening in Russia and the US.
