Bitcoin is the mortal enemy of 'tracking'. Therefore China is going to continue to assault Bitcoin from every angle. You can be sure of that.
This is where China and Russia are going to clash soon.
Russia is essentially using and supporting Bitcoin because it is neutral and independent from the global FED led Central Banking System and its FIAT money system... however Chinas Central Bank is still partially under control of the same FED led central Banking System that promotes FIAT money...
