I have visited many online casino and most of them except athlete program where you can share your referral link with friends and family but the only time you get commission is when you're done lines stakes on games, you get paid some percentage of their winning or loss.
I don't think casino websites referral program are the best because not everyone is interested in gambling so not everyone will be ready to stake so therefore, you won't be able to earn from referrals.
