Ignore whattomine, it is showing 20% higher daily income than what you actually get.
Unfortunatelly whattomine shows more profit (about 15-20%) than suprnova gives.
Why is that BTW? I get a reward based on my own calculations here and it matches the one from WTM:

Maybe suprnova fakes the luck and it's 120%? Who knows)
