Minning with free electircity

How profitable could this be, with approximately a 5-7k setup. Free electricity. Just looking to see if this can pay rent in one of my properties.

Thanks

Its almost always better to just buy the coin than mine it. Reason I say this is because hardware keeps improving and profits decrease as difficulty increases.

it would cost you a fortune in hardware

Economies of scale matter here. Having a couple of hundred miners at play? Free electricity for the heating? You've got yourself a profit. But doing this at home? The difficulty will increase so much that you'll not be able to be profitable at all.

Better just buy and hodl it, with 5k setup, you probably will make only two two rigs.

You'll need one of those 10k USD miner rigs to actually earn something

You need a good mining rig to be really 'profitable' and it would cost a lot for the set-up. And it's too late to do that now. With your 5K, i suggest you go with trading.
