You can use amd cards like, rx470- rx480 rx570 rx 580 rx550, rx590 you can mine only ETH not solo, and not shit coins etc. because you have free electricity. dont waste your money with shitty expensice cards.
If you have free electricity, then the truth is where you can play. But if there is a choice to get profit in a liquid token or double profit in shitcoin I would choose liquidity.
