China bans Bitcoin many times in history and let's do retrospectively check on what happened so far
If you look at those chart, data and the article, you would realize that China ban events don't have long lasting effects.
The chart says it all, one country doesn't entirely affect Bitcoin, well, considering China's population and how big this country is when it comes to resources and such, it did made an impact but such impact was recovered right away. Also, I do think that there's still a way for China's citizens to participate in such activities but in an illegal way, of course VPN won't work anymore, I don't have any solid proof but there must be a way, right?
