Commission Rate is 10% by default (10% of what your referrals wager):
Being a Stake affiliate means you will earn money on amount wagered - which unlike traditional affiliate programs, includes money that is both won and lost.
I can't find any concrete evidence, but I'm guessing the commission rate is 10%
of the house edge, not total amount wagered.
Similar crypto gambling sites have adopted this affiliate structure, as opposed to traditional CPA (cost per acquisition; ex. earn $20/new depositor referred) and Revenue Share (affiliate earns/owes X% of referred players wins/losses) models.
Yes, it is the %10 of the house edge, they explained it but really hard for many of us to interpret it in right manner. If your referral gambles 100 bitcoins, you get 0.1btc not 1, not 10, which means you are literally getting 10% of the house edge not all of wagered amount which would be stupid, why would anyone give you that much money.
Maybe wording on the affiliate page could be changed to 10% default house edge profit instead of
wagering but in the end that "wagering" was put there so you would know that it is not only on losses but also on wins as well, if your friend bets 100 btc and wins 10 btc, you still get your 0.1 btc, if he loses all 100 btc then you still get 0.1 that "wagering" means exactly that but you get 10% of house edge not all wagered.
