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.
I don't think people would be panic selling at that time. I think that most bitcoin users will just be 'chill' about it because there's nothing to worry about. Most of us are computer literate and we can all understand how VPN works and what it exactly does. Bitcoin being banned will only get non-bitcoin users more scared to try bitcoins. But looking at the bright side of it when that happens, it will be in the news. Maybe that can even be a way for us to find new whales that would pump the market.
