There is always a possibility that this will happen but let's be positive. There are other countries who welcome bitcoin with open arms so don't worry that much because bitcoin is already legalize in some countries and there are rumors going around that another Asian country may legalize bitcoin. They may have seen that they just cannot easily ban it and the technology behind it has potential that's why to take advantage of it, they would just legalize it to have shares of the transactions.
China has a big impact in the recent announcements they have made saying they ban bitcoin but then again there is a news again that they would just regulate it not ban it so it is not clear. Nevertheless, we should not be that affected anymore to this news because China is just one part of the market share of bitcoin, not the whole market share.
