Not sure if if BTC and ETH mining is still feasible i India. High electricity cost and rentals if you do not have a space will never allow you ao make any profits. Also add to that equipment costs and its wear and tear and maintenance which will make the burden more to it . i think instead of mining ETH actually other altcoins which seems to have a good future and available very cheaply should be mined.
India has among the cheapest electricity costs in the world. See, e.g., https://www.ovoenergy.com/guides/energy-guides/average-electricity-prices-kwh.html
