Japan seems to be embracing Bitcoin exchanges while China is trying to outlaw them. I think China will probably not be successful in holding Bitcoin down. I have a feeling that their plan was to control 51% of the Bitcoins and they decided that they couldn't gain control so they want to start their own cryptocurrency and try to force Bitcoin and others to fail. I don't think it's going to work even though China is a powerful country. Bitcoin is worldwide and has grown too strong for China to be the cause of it's failure.
