i have never used them but they seem like a waste. you're better off just buying a used Antminer S9 for $150, installing Braiins OS on it, underclocking it to 800 watts, and calling it a day. Bitheat used to mine shitcoins 😉 I don't know if it still does.

I’m looking at mining rigs today for reasons 😂 are the S9s still competitive? I know enough about mining but not the nitty gritty on specs.
If it makes any difference the electricity cost doesn’t factor in
