Oh, that makes more sense. We're confused because this would require an enormous amount of electricity. Your office doesn't have enough power to hook up $50,000 of mining gear. $50,000, at $200/TH and 0.5/GH, will take 75 KW, which is way more than your office has. Unless by office you mean industrial site.
Why is it so hard to believe that some people have free electricity.
I also have free elictricity at my office i rented.
The electricity cost are charged at a fix flatrate.
However I tried with some miners and office became loud and miners run hot, so I cannot use my unlimited electric power.
