there are several terms and conditions binding referral bonuses as some casino might even require you to wager the total amount of the money gotten and you’ll agree with me that in most cases it is always difficult to achieve such and at some point there are also people who are already making it really big through referral bonuses but the percentage is relatively insignificant.
A casino that requires a wagering requirement for those earnings and revenues got from a referral?
I doubt such terms exist. In most cases, revenues and earnings through affiliate commissions can be withdrawn instantly and freely. If there's a term like that as you say, I doubt that casino will lure their customers to their affiliate earning section.
Just out of curiosity, what site does have those terms?
