If you're in India, the sensible thing to do is to stay away from bitcoin. This is based on my conversations with my brother who is a tax lawyer. According to him the legality of btc and the laws that govern its purchase/sale in India aren't clear at all and there is an expectation that the RBI will clarify the regulatory framework and the laws that they believe apply to btc. He also believes that RBI has historically favoured extremely conservative interpretations so they will likely shoot down btc. This is obviously not legal advice, not least because it's coming through a lossy channel (me).
