How can China control btc? USA is no.1 country, I think USA can control btc, because they have more fund than China.
China has:
A) 10 times as many people
B) 10 times as many mining farms
C) Mining farms that are 10 times bigger
That's how, its not the chinese Govt Vs The American Govt is just a numbers game , the more people you have working together the more control you have over Bitcoin
There's also the investment numbers game; if there were people in the US or other western countries that wanted to out in as much money the US and/or whoever would control Bitcoin, and that's basically the same as China controlling it. The numbers in China just mean a smaller investment per capita.
