My past 7 days earning $0.86 after I increased reward.
But at start when reward was only 100 saotoshi for 30 minutes daily revenue was approx $0.5 .
Visitors are same in both case but earnings are not same can't understand this behavior of visitors.

100 satoshi is not interested for most of users, especially users from country where is highest payeed per click.
with low reawards, you target visitors from country with cheapest pay per click.
With 100 satoshi reward I was getting better clicks from visitors and 50% from us but after increase of reward up to 500 no click.
