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.
