Sorry, I just went to ask my Chinese friend.
The news I got was that China did not ban bitcoin transactions.
It's just tougher regulation.
I also don't see any news that exchanges stopped trading bitcoins.
Meaning this is just another fake news. An untrustworthy statement broadcasting on the internet. Maybe the intention of this negative news which is not not real was to create a fud so that bitcoin will again decrease the value and people behind this news will buy bitcoin collecting the coin as much as they can. They really know how weak hodlers response in every fud.
