Lol true but the idea of mining ETH and get 1 ETH with your Miner still active is better, this way you get more ETH after making your 1 ETH back.
Yeah buddy, do I look like a rookie miner?
I'm more like retired miner.
I can use 2500$ to buy 8x rx580 8GB graphic cards right now, there are no cheaper cards than this but if the electricity bill is high it's better to stick with rtx3060s or RX6600XT but you get a lower hash rate anyways.
Right, the prices very much depends on your location. RX400 and RX500 series are good old cards, still probably profitable but not for all. You can get them over 30MH/s at around 100W (of course it can be better, but be realistic). You have to do the math.
Also when buying used cards do proper cleaning! Then fast test on some cheap computer it might blow your PSU if the card is shorted (otherwise check for shorts first), if all good repaste them with good thermal paste and maybe also new thermalpads (not necessary most of the time). I use Artic MX-4, because it's cheap and pretty good, it won't get much better with very expensive thermal paste.
I remember buying new RX470 4GB in like 2017 for something over 150 USD because nobody wanted them
