Well that's not a ban, the same as the rules made by the central bank of my country, in my country also prohibit the use of Bitcoin as a means of payment to buy goods, because the purchase must use the State currency so if we have a coin must be in exchange first with the currency new paper can be used shopping. That's what I catch on seeing the article above. Sorry if I think wrong.
Moreover, India has many who use blockchain technology. I'm sure there will be no restrictions on India.
