i won't simply do it at this point, there is no real room for profit, too much competition, and too much money to invest for a little gain, it's better to buy bitcoin directly with the money you would invest in your farm

and these large mining operation need in the first place, a large building with proper cooling solution and dissipation, which alone cost already too much, also yes it must be build near an idro generator to have a rate lower than 0.5 if possible

the mining with bitcoin is a dead horse, your only way now is to buy few miners just to have a rounded income added to your salary, but not as a main income
