whattomine doesn't estimate very well i think. I am mining ZCL, but i only get a half of what they estimated. It is the same thing for other coins too. Maybe it is because i am using a laptop? But the laptop graphic card version should be equivalent to the desktop for the Geforce GTX 1080 i think.
I have another laptop mining with cpu only. And now i can only mine 0.2 ETN every day... Last week i could mine 1.25 ETN every day.
