Specialy china, koreans and japenesse those people are crazy in their minds and destroying the bitcoin, they increased fees and everything fuck chinese niggers
Destroying bitcoins? Nah, you'd have to wait on the EU for that. The French and German finance minister insist cryptos be discussed on the next G20 meeting, so say hi to more regulations.
I agree with most people here that the countries you mentioned did more for bitcoins than others. Many bitcoins were mined out in China before they started closing mines down and imposing stricter regulations. Japan and South Korean governments gave bitcoins an air of legitimacy before the futures in the US came about.
