This is going to impact only the Indian cryptocurrency market that, with all due respect, it's not very important. We survived the actual ban from China, not for bitcoin only but for mining as well, having or not having India won't change things, I just feel sorry for the Indian people.
I mean I wouldn't say its not very important? Because according to statistics, India has the most "number" of people owning crypto. Just by sheer number of people, it has the "largest user base", 100 million, compared to the ~25-30 million in USA. Sure, USA still has the most trading volume and India isn't even close, but this growth in India has been just in the past 1-3 years. The growth is exponential, mostly due to the median age of Indian population being 28.4 yrs (Source: worldometers), and them being eager to learn about new technology.
To be honest I'm very surprised to see that 7.30% of the Indian population own crypto, it's way more than what I was expecting. Anyway I don't change my mind, we always looked at China as one of the most important countries for the crypto world, they banned bitcoin, closed down exchanges and mining factories, and yet we're still here. At this point I'm curious to see if the Indian government will understand that this 30% tax is not gonna help anyone.
