BetWinner Affiliates
Commissions: 25% revenue share.
BetWinner is a popular online gambling site. They focus on sports betting but also features a casino, poker, bingo, lottery, and more.
BetWinner is translated into LOTS of languages.
They offer a base commission of 25% lifetime recurring revenue share. This rate can be negotiated a bit higher by asking one of their affiliate managers.
I would assume that how good of a commission rate you get depends on how much traffic your website has and how many customers you can send their way.
