-nofee: set "1" to cancel my developer fee at all. In this mode some recent optimizations are disabled so mining speed will be slower by about 5%.
   By enabling this mode, I will lose 100% of my earnings, you will lose only 2.5% of your earnings.
   So you have a choice: "fastest miner" or "completely free miner but a bit slower".
   If you want both "fastest" and "completely free" you should find some other miner that meets your requirements, just don't use this miner instead of claiming that I need
   to cancel/reduce developer fee, saying that 2.5% developer fee is too much for this miner and so on.
