Hi. I am mining on ultra.leetpools.com, I am receiving very few coins with 170kh/s, When I am using coinwarz calculator I should be getting 80 coins a day but in leetpools I only got around 40-50 coins.
You can't simply compare to coinwarz which calculates the # coins based on a single difficulty of that exact moment.
Difficulty fluctuates more than 100% at a time depending on the time of day due to less/more miners hopping on/off.
So if you went to coinwarz even 15mins later, the estimate might have changed dramatically.
