if bitcoin was banned there would be a huge negative impact on the price for sure it wouldnt even matter if some of the people would still use it everyone would dump their all bitcoins to get rid of it and take out as much money as possible so lets hope this thing will not ever happen.
Of course there is an impact, but I think it won't be that big anymore, most probably those who are earning bitcoin are the first one that would quit, but if you are making profit from your capital, then giving up would be your last option... It's like a forumite being banned for copy pasting, quitting is not their option, instead they will find a way to make a new account or buy one to copy paste more...
