It's a big consideration when you do a lot of mining. I run GPU miners and it's $100 a month or a bit more at $0.12/kWh to bring in $150 a month in crypto for a single machine.
That's mining at current prices however and the ratio tends to remain stable when the coin goes up and down in value due to the difficulty, if you're mining for a loss expecting an increase in price later that can work as a delayed profit.
You are right. But ... you are a pro who invested in the miners intentionally and calculated all the ins and outs.
On the other side, I am an amateur with sole CPU doing this as an experiment. I might stop at any time.
By the way - I am getting more satoshi from the bitcoin faucets referrals but that's another story.
Anyways, thank you very much for your valuable input!
