China tried it in 2017 (that was my first experience) with a ban. I saw how that panned out and how the market shook then. However, there's nothing much that happened after a while as the market reshaped after a slope and picked from then after the Chinese ban that saw many exchanges leave China, including Binance. Today, whenever I hear a country is trying to ban Bitcoin I ask what is there for them to achieve other than noise. For all I care, India can go ahead and flex its muscles. Nothing much will come out of its noise.
