I think most of the websites have almost the same referral bonus. Maybe a little percentage is the only difference and it is negligible. You won't really notice the difference unless the difference jumps up to a 15% interval. But if it isn't, you won't feel it much really. In addition, the referral bonus won't really matter that much unless the person you referred to is active in gambling. Because there's a rule I suppose in this referral rewards system in which for every bet your referred person makes, you will get a little percentage. So if the person you referred isn't really using his account, you will hardly get something in return. I guess this rule was made to avoid being abused by people who are multi-accounting. I suggest instead of actually finding a casino that offers a high referral, check instead of a well-known and reputable casino that could take care of your funds and you can really say that worth the risk because not everyone on the internet is worth it. There are so many complaints on the scams and accusations board if you'll check so might as well go and find the most trusted and reliable one.
