The newer 21 generation miners are profitable. Depending on what difficulty and price does, it's not guaranteed. Older 19 series miners not so much. All of this changes if and when the price runs up.

When you are mining in the bull market, it becomes extremely profitable. I would love to discuss more, and I kind of assume I'll try to talk you out of it if you reach out because it's going to be more difficult for smaller scale miners to be successful going forward.
