Well the only thing i do know is that India doesn't allow gambling, and the most people are buying bitcoins with that purpose, soo you must find some place were you can buy bitcoins, maybe travel to other country buy bitcoins and then sell them, i dont know how expensive it may be but looks insane prices fluctuating such in one single day.
You are right about the fact that India doesn't allow gambling. Most people are buying Bitcoins with that purpose: I Highly doubt that statement. People having unaccounted cash are the core individuals who are buying lots of Bitcoin today. I think I need to dig deep into travelling to some other country and trying to establish a channel for the same in a legal way.
as i have some friends from India and they regularly play gambling very openly, then how is it not allowed in India. and the second is that Bitcoin is not only using in India as it is a decentralized global currency of the world, it is in most fo the countries of the world and majority of the people are using it for investment purposes, as they consider bitcoin as one of the most safe and profitable investment.
