How does that help?
Mining produces heat => warm room => profit covers power costs to heat the room
(needs very cheap elec, of couse)
Very optimistic view on counting the costs of mining
I have a very cheap electricity but even for me and my PC it's hardly profitable to mine with GPU. No doubt GPU mining is dying and there are less people who'd like to spend a lot of money on the gpu miners/ graphics card/ electricity / etc
Sell your GPU before the next generation comes..
