I don"t Think that bitcoin's future dependent any country or any goverment . If the bitcoin will be usued in all the other country of world India and China will not have a chance expect legalizing the use of bitcoin .
You're right, Bitcoin does not need to rely on any country or government, it needs is demand, if no one is willing to use and invest bitcoin, bitcoin will not survive, the biggest feature of bitcoin is its technology, founded the first to encrypt money, China is now in the study of bitcoin phase, bitcoin is still promising to legalize in China.
