Green energy for bitcoins, ethereum, and other cryptocurrencies mining. Dago Mining has one initial cost and zero cost on consumption. The cost of the energy component gives profitability to mining. We create our own green renewable energy power plant and we will not have any future energy cost increase. There is no cost per Kw schedule, only a small annual maintenance price (0.01 $ per Kw), with a 20-year warranty on plant's components.
