China have destroy bitcoin and make all of mining bitcoin project at their country have closed, many ICO investment was die by China have banned of regulation for ico investment at their country, China have more power fo destroy how bitcoin price.
China is the most powerful country for crypto currency market that's obviously truth. But china not enough powerful to kill Bitcoin. China can just FUD Bitcoin to banned it and regulation in ICO investment.
That's right, China not enough powerful to kill Bitcoin although they have most powerful country for Crypto market,
I am sure they will use Cryptocurrency as a valid of payment in the future. I believe that all countries are not able to kill the Bitcoin.
