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.
So I wouldn't really say the country with the most people adopting and trying out the technology is "not very important", it might as well be in the coming years. And this 30% tax and TDS is definitely going to hurt the enthusiasm among adopters.
