India is just too afraid of the capability of cryptocurrency and with the power and profit it could give to traders, in which they cannot imply nor track all of the Indian or any people that resides to india that trades with crypto and gains in it, nor tax them with such activities. All they can think of is banning it, it wouldn't take years if they would simply ban it with the India's Internet Service Providers or Telecom Companies, unless the court would progress slow with the investigations and the implementations of the law. It's a normal case in many countries, but it usually just fades away with the fact that they couldn't handle the vast network of crypto.
