How does China rank? Aren't most Bitcoins mined in China? I know the government over there is a little strict, but it doesn't seem to affect Bitcoin as much.
Indeed they mined the most but they aren't crypto friendly place, just remember how they banned icos.
While the source OP cited was posted last November 2018 and obviously not the updated one and many surely happened in crypto space hence progress and perspective in every country towards crypto.
