Oh, +100% was the upvote return, so how much you get back compared to what you have paid (so 100% means that the upvote payout will have the same value of what you have paid).

Currently the minimum ROI now is +1% and max is +20%. The information is currently not displayed because no other service is displaying it. And I'm trying to be competitive here :)

Do you think it would be better to display it? It seems to me that users prefer to try their luck with bidbots without knowing the ROI. I'm trying to be inline with this.

very nice, as long as it's not negative I like the "luck" factor. Great job !
