In general, the Chinese government is not comfortable with Bitcoin as it indeed representing a different currency that they can not control with. since Bitcoin is decentralized it would be hard for the government to make interventions and so they are thinking that maybe it is time to ban it altogether. The government can not kill Bitcoin but what they are doing is actually closing the country as a market for Bitcoin.
So the question is: Can Bitcoin survive without China? In case, it can't then then there is something wrong with it since it is not resilient to ride the big storm it is in.
Yes it is true, China is a big contributor in the digital currency and in the bitcoin. We saw that, when the bitcoin fall down a few weeks ago because of the issues in the China. But now, bitcoin is gaining itself and surpass its value back then. It survive and became better than before. So even if without China, bitcoin will still grow and proves itself in the digital currency.
