IF war with China should happen this summer with the UNited States,,, could China hack Bitcoin if it had to regardless of cost?
Simple answer... no. As we can see China will rather focus its monetary fund for warfare than spending billions of dollars hacking the Bitcoin Network. It is illogical to hack Bitcoin in the middle of a war. It will only hinder China's war campaign than help it with funds if that is what you are thinking of asking the question about the possibility of China to hack BTC.
