Bitcoin mining Is not as profitable as Ethereum mining so get a setup computer make a rig of at least 6 graphic cards if u really want to earn the profits and register with any mining pool search on Google for mining pool
If you have a mining rig reply me here and I can guide you. Also mining produces a lot of heat. You need a better cooling system as well. Also also, mining ethirium, cardano, stellar would be better than mining bitcoin.
