I think its important to have basic data so that we can get a clear picture about its adoption and rate of growth.
You will not know exact number of users in India as there is no standard site available where users need to registered if they would like to trade in bitcoin. But yes you can ask exchanges in India about total number of users registered with them. But it will just give you a very fair idea and not even a close numbers to actual users.
Even a rough range will give us lot of information. Like less than 50000 users .. Or between 50000 and 1 Lakh users .. I don't think its more than 1 lakh users.

How many of them are from India?
My estimate would be about 400-500k users in India and easily adding up 20-30k new users every month.
Most of them are from India.
