I have not been mining but I understand the bare minimum and the infrastructure you need to get into mining.

You need to run the ASICs and have cheap power to power them along with cooling and maintenance to mine.

Considering the following facts:
1. Cost of buying ASICs and importing them to India. Note the pleural, you will nee a LOT of ASICs, not one.
2. Power is not cheap here
3. Ambient temperature throughout the year is warm, not cool.

The return will be from the coin you mine and how much you sell it for on the exchange.

... mining is not profitable venture to get into.

You could and should learn about mining from youtube channels out there and the Mining section of this forum, but it is much easier to buy and sell bitcoin for profit than mine it any more.
