Aren't 65% of all bitcoin miners in China? Couldn't the CCP sabotage the network at any time? Say, a month before the launch of their digital currency?
This specific visualization is limited to 37% of the hash power on the network. It's possible that it is a representative sample, but I don't think we can assume that.
Even better, it is limited to pools that primarily operate in China. I really wish someone would turn off that link. It is really awkwardly bad and mis-quoted a lot.
