China and to some extent India are definitely two of the most important markets for Bitcoin. But that doesn't mean that Bitcoin is going to die without these markets. The two largest markets are Japan and the United States, and thankfully we are not facing any major issues with these markets right now. China and India are important, but they are some what disposable.
China in one hand talks about regulation meanwhile india has religious people in power who are backed up corporates ,so they will not support any development in science and technology
