Well if more Governments ban Bitcoin , this is good for anonym coins like Onion. But in my opinion you can t ban Cryptocurrency , people will always find a way to use their crypto coins , no matter what the government says.
Once something becomes illegal is when it peaks the interest of others. Human nature tends to make people curious about things you're told not to do although early on in the game it is still to early to think about any implications that may be disastrous to BTC as they have no direct correlation.
