Anyways, for me this is just a theory and of course it will not happen. Its given that China is a huge market for cryptocurrency, but we still have Japan, U.S.A and other great countries in Europe who keeps on supporting Cryptocurrency. China has no choice but to adopt this one and maybe make their own Coin to compete with bitcoin.
It is a theory and will always be a theory and there is absolutely no way China can really have that much of an impact, no matter how large the market is and even if it will, it could only end up having a temporary impact and trust me, with the way things are going with the crypto space, the level of adoption daily, people's belief and the fact that things would keep evolving with so many countries getting to see the great benefit, it will be hard for a single country to think they can make such impact in the long run.
it's just fake news, you don't get easily influenced by false news like that, the government will not be able to ban the circulation of bitcoin in its country.
Yes, no government could stop cryptocurrencies. I read in some other discussion total Asia weigh more than half in total population and then in bitcoin holding too. Hence, I believe Chinese people nor their government cannot do any harm to bitcoin ecosystem intentionally or accidentally too.
