Earning $430 for month by bitcoin mining. What about the electricity costs?
If you factor in electricity costs and the money they spent on infrastructure(GPU's and high-end machines), it is a dumb idea. They could have spent $30-50 on heating equipment instead.
Electricity costs are probably subsidized (since otherwise in places where it gets super-cold it wouldn't look nice if people froze to death for inability to pay their power bill).
Electricity costs in Irkutsk (place where the place that the video is describing is located) are 0.7 RUR per 1 kWh for rural areas. That's about 1 cent per kWh. For comparison, California's lowest tariff in about 20c per kWh and if you are consuming a lot (which you'd do if you mine) you'll get over 35c/kWh. If you qualify for low income subsidy, though, you might get it for significantly cheaper :)
