China has become the powerhouse for Bitcoin (and the whole cryptocurrency in general) as it is hosting many Bitcoin miners due to cheaper electricity and maybe also cheap labors. China also boasts of probably millions of Bitcoin owners and traders who are influencing the moves of the market on day to-day basis. As far as acceptance of Bitcoin in China, it is comfortably good until such time when the government decided that it is time to intervene.
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.
Bitcoin can survive without China, but it is obvious that a shock is going to happen if the Chinese get completely out of bitcoin, however after some time bitcoin is going to go back to normality, I do not think that bitcoin viability is going to be at risk let alone its survival, so if they want to get out, let them since there are many people in the world that are willing to buy their bitcoins and create their own mining farms.
i dont think so that BTC will be dead with out china...because BTC now have came the worlds top crpto currency..but keep that in mind with out china BTC have to take some time to higher its value.
