Well technically, it is not allowed to complain about voting rewards on the forum.
And if you stop biching like 14 yo schoolgirl for a second, I will explain to you some vote rewards mechanics here...
Admin <<< this guy here, has some advanced economy competence, so he understands inflation pretty well.
As logic dictates, he put some sort of reward limit. Each time reward is given , there is less chance for you.
(Well, maybe Abaddon or someone else, but one of those guys for sure)
As this drunkard told you: "Try to vote at different times."
(Remember when you get more silver, vote then)
Voting with 1 PC, the reward is not that much, but if you vote each day, you can spend some weekends on premium, or feed a premium pet.
(For 1+ PC , there is another story)
