And I knew some guys tried mining in 2020 or around that period and said it is not profitable at all, so they sold the equipment and bought bitcoin with it.
BTCitcoin mining at home was not profitable even in 2014, so there is no way anyone could dream about getting a profit mining
BTCitcoin after 2014, that being said it was profitable till 2013 until Avalon and Butterfly Labs came with their ASIC machines and started mass shipping later that year. ETH mining was different and it was profitable in the beginning.
I had a setup a couple of years back, but I sold the entire setup and kept just one card when ETH moved from PoW to PoS. I was mining ETH back then as I had a GPU rig consisting top end unlocked cards. I did make decent profit back then. I remember I was able to recover the entire invested amount in under a year which for me was a great ROI. I do have a friend who still has a small setup and mines using HiveOS. He is still able to make profits but is on the verge to sell his setup so I guess he is not really happy. You can consider various things like hardware cost, maintenance, rent & electricity, etc before you can jump into mining.
ETH moved from PoW to PoS in September 2022, so were you mining other tokens after that or you stopped mining altogether.
Anyone who pursued mining even after AMD Radeon RX and Nvidia GeForce GTX 1060 doubled their price since the demand was so high, huge respect to anyone who followed that path, personally was furious as it was so hard to get a good graphic card for gamers especially during COVID period.

Mining now can only be profitable if someone is not really paying for the electricity. In rural areas, people usually hang a wire to the main line and start using the electricity for water pumps, etc. Mining can be profitable in those kinds of places.
Imagine you get free electricity, mining
BTCitcoin is a costly affair. You need the infrastructure and ASIC machines which will cost you millions and you cannot run a mining farm without the authorities noticing as it will consume way more electricity than any small factories.

AFAIK, the government offers only upto 78 thousand rupees for 10KW solar for house and commercial purposes won't even get that but that is not really needed, they can do that with imported panels to even lower the cost than the subsidy amount.
There are different types of solar grids available, the best cost effective is ongrid which doesn't require battery and will be connected to main electricity meter so you can transport excessive power from your solar setup to the electricity board and retract them later with zero cost but this is not ideal of minin which needs to be run 24/7, so the off grid is the best option but adding battery is like adding 100% capital to the setup.
Lets say we use Bitmain Antminer S23 Hydro Bitcoin Miner, lets say you can cover the cost of ₹12,37,801 per machine, you need 35 kW solar panel system to run a single machine.
