If you have any of these cpu at home it's better to star making money out of them right now before it's too late, I owned 5 different desktops and I'm making 12$ per day with free electricity

1. AMD A10 6790k 1.19$ @ 479H
2. Core i5 2500k 2$ @ 830H
3. Core i5 3470 x3.  2.99$ @ 1200H


If you have even XEON or Opteron CPU now is the right time to put them to work
