They repeated what they had done before. I do not understand what the Chinese want to do. They keep banned bitcoins. Then they open bitcoins
Where in the news did you see China saying they have banned bitcoin. Apparently, you did not even read the link the OP dropped. China did not in any way ban bitcoin, but shut down exchanges until they comply to their rules of opening exchanges in china, leaving only two to be operating presently as far as I know. Whales only used this to generate FUD to make weak hands drop their coins to their benefit and shame on those who fell for it.
