People are starting to understand how difficulties work now and that Mining is ONLY profitable if no one else does it. And if everyone also does it, the only way to be profitable is to have the cheapest electricity. So IF you don't have the cheapest electricity (say 0.03USD/unit) then lol, good luck. All the calculators are fake, they always have been. They were great for making money off greedy and stupid noobs though
You need low ambient temperature and fast cheap internet to scale up effectively.
Not just electricity.
