Both profits, but affiliates has more chance to make profit than referrals.
Affiliates has lots of benefits, it has wide range of rewards also like tiers/levels for every user they invites, the promo used of their invites, and you dont need to have an account on the platform, every bet they made, mostly it is used in different platform to promote the specific service, say a casino.
While referral is just a fixed rate or percentage whenever a user invites to the platform, every bet they made. A referrer also is a existing user of the platform/casino.
I disagree. It is pretty much the same. It just depends on which is which was REFERRED. Basically, Referral System mentioned by the OP is the one A USER USES to get AFFILIATES. Hence Affiliates are those THAT ARE REFERRED. But some platforms uses both terms is just their referral system in such ways like "affiliate links" or "referral links" that pretty much pertains to the same thing.
From what I have encountered from the casinos here, mostly, you can interchange these terms.
The difference is how each casino give the benefits of their affiliates/referrals and how they define it.
So if you want to get the benefits of this feature, better check the conditions of the casino itself.
Because their terms vary from one another, the privileges attached to it and other things related to this category.
In which one you disagree? That affiliate has a chance to get more profit?
I'm talking based on my experience as an affiliate and also uses referrals, my experience is not just about gambling particular but mostly finance apps that offers much as an affiliate. And its proven that affiliate have more chance make profits.
In much legal form, affiliates needs to provide legal documents, have platform where they can promote the service e.g. facebook/twitter page, website and needs approval from the service before they can promote the service. Having affiliate link is also not just particular to get new invites, but also bought products/service. While referrals is particularly on inviting new users on the platform
