Nobody cared when India "banned" bitcoin, nobody cares if India unbanned it.
Despite having 1.5 billion people, India means close to zero for the market, 90% of the people there can't afford to buy anything other than food, how do you think they will manage to invest at much as the other countries?
Well.. I am not going to argue. I am from Nepal, which happens to be one of the countries that border India. A large part (may be one-third of the population) of the Indians live in poverty, but India is home to dozens of billionaires and thousands of ultra-high net worth individuals. If China is an important market for Bitcoin, then we can say that India is also one of the major markets.
