Not with cash no, I've got 2 PC's that sit and mine alt's through Multipool which I then exchange for LTC.
Problem at the minute is one of the big exchanges died and another is in a bit of a hole meaning the value as a whole has dropped, the LTC I convert into for instance since I have been mining peaked at $35 per coin, its now sat down near the $15 mark.
Its not cost me anything other I wouldnt of spent other than electricity, but given both of my machines are in the office on the back of the garage I would normally have had the heating on, I havent needed to since I started mining and heating costs more than the electricity for the mining rigs so I'm not really making a loss.
