But it have to be noticed, that even with some posts getting to 0, he still gets a pretty good reward.

Last time i checked, i his 9-10 days (dont remember wich one a checked) ago posts, he had some 0 posts, but still were able to get around 320,00 on rewards.

The other days he probably still get a pretty good amount, because 10 posts a day with $200,00 seems pretty hard to zero his total daily reward.
