Clevermining's reject rate is a loss on it's own...i would personally suggest move to megamultipool, you would suddenly see why right now nothing compares...have you heard 1% reject rate for a damn multipool, megamultipool does just that! I doubt any multipool comes close to the earning per MH that megamultipool is offering right now!
what is it offering? any place to check that?
No idea how luthan thinks megamultipool is profitable... when you look at their mining history, they are consistently below .008BTC/MH/day...
