The high fees are hurting your profitability pretty badly. Instead use an altcoin to move your money to the exchange, and let the btc accumulate there a while before withdrawing.
Profitability for my rig seems to be right on the ballpark.
What altcoin do you use for moving to exchange? Ltc or something even more cheap like Music?
If your miner reports that it is earning X btc (like MPM does) so you see around that amount in your autoconverted altcoin?
Trying to figure out these nuances now... Thanks!
