In 5 years we will be very surprised by the cost of bitcoin. But the fact that India is connected is waiting for the whole world. Soon we will see new record growth rates of the Crypto-currency.
I agree, India and China have pretty much half of the world's population. Although India is overall a poor country I think we are going to see some changes in the price.
Though as said in some recent posts here bitcoin is not really legalized in bitcoin so they can still have a decision that will really change the price. Not only India is making a move in the Asia, there is a lot of people there that are making their move to own their bitcoin, there is a lot more, and there are also news about Bitcoin will be regulated in the Philippines.
