I don't think so its even possible because the Crypto market of the India is much larger as compared to other countries even some great projects as Polygon Wazirix rxchange and some other famous projects having big market capitals are developed by indian community so. Ban is not a solution make some policies about it why don't they understand. They need to understand the popularity of they crypto market and its influence towards new generation.
They decided after any reason. They imposed the tax on crypto users but I think they didn't get any benefit. Therefore they called that.
But you are right there are many other solutions. Ban is not a solution.
If they do that then black market will come up.
