Service like paypal is still illegal or unauthorised ,idk . So how do you expect btc to be legal in india. Basically its simple govt cannot earn from btc , govt is still only finding a way to how to earn from btc as they earn from corruption money which is way too much and this is how India works. govt knows all the pros and cons of btc , and they cannot simply make it legal and earn from the fees of these exchanges. So all you guyz having dates for btc announcements from authorities and hoping to find an answer , dude its a very long run in India just within a month after taking btc into consideration it wont get legal. Paytm has got just permission to be a bank after years that too with the lowest limits .
Its people like you because of whom my father was asking me the other day : " Is bitcoin illegal in India?" It isnt illegal and never can be. It only depends on the way you use it that can make it illegal. I have seen people using it for money laundry and at the same time I have seen people filling up taxes on bitcoin. Its just the way you use it.
