There is a lot of uncertainty about GPU mining right now after many asics have showed up for many coins including XMR which used cryptonight algo and was considered to be ASIC-resistant. XMR had to hardfork to brick all the asic and the huge amount of hashes which was brought to the network.

I wouldn't risk investing in mining (especially since you live in India) as the situation is the worst after the RBI's new regulation on cryptocurrency. Spend your money wisely, don't jump in without proper research or awareness about what is going on.
