We have five in different locations, only 3 I have to pay the power bill.
At the rate we are going I plan to stop using them in March/April of 2014.
Since we started until two weeks ago we have over 900 bitcoin.
Twice I sold 150 of them when the price was very high
It is like a dream getting this but just thinking if we started 1.. 2.. or even 3 months before we did it would be unreal
