Most Chinese citizen has bitcoin mining farm when the going was good, the largest number of such industry exists only in China.
Does China Control Bitcoin? China dominates bitcoin and can easily determine its fate and that is the major reason behind the spike in btc price whenever the Chinese president says anything about it unlike other world powers.
I disagree with china can determine the fate of bitcoin. There is a large user population outside of china. China has banned and unbanned bitcoin more than I can follow. Bitcoin kept plugging down the road, china can do what they want it wont affect the long term viability of bitcoin
