India need too much time to adopt bitcoin like China and Indonesia because here most of things control by strict government policies so they are not allowing peoples to involve in this right now but some peoples trying to spread this which is very good signal
Yes it will take time but now I think it will grow at much faster pace because even government is promoting digital payment system.
People's trust on online transactions is increasing day by day in India hence more and more people are attracted towards Bitcoins. Soon India will also on the same track as china and Indonesia in terms of usage of Bitcoin.
