This is a serious discussion. I mean, after I've seen how bitcoin (and other cryptos as well) got dumped badly after an irrelevant law that makes ICOs illegal. I can only imagine now what would happen If more countries do the same thing and It could get worst by make itself bitcoin illegal. Whether we like to admit it or not, most of people would sell everything they have once its made illegal, some may continue to fight the central banking but the sad reality is that as soon as people start making profits, they will dump it and move on.
The central bank of the Philippines is also against to bitcoin. I think they do not accept bitcoin as a way of income of we are going to open an account to them.
It is not yet the government itself but it is very powerful. So expect more when the government is the one who give decision.
