Well Said by Nischal Shetty.
Cryptocurrency is the most searchable topic on Google in recent times. It's not just about its growth but also it is considered as the future of Digital payment across the world. Big celebrities like Mike Tyson, Elon musk, etc are jumping inside and openly supporting BTC which gives it more hype and a sense of trust among the masses. If India Ban BTC, it's like missing a global investment opportunity, and definitely India will be tagged as CHINA in this free world.
So I think It won't be the solution to ban crypto in this modern era where globalization, technology, innovation, and free trade are connecting the whole world together.
