My country is pretty chill, so there isn't any regulation against Bitcoin as far as I know. With that said, I think if we go much further down the line and Bitcoin price/value increases a lot more than certainly at some point it is going to be regulated by every country's government no matter what.
Which country is that? Mine is very angry and rigid against bitcoin they're discussing to tax bitcoin under extremely heavy conditions. This won't be good for people interested in crypto down here.
