I got close to 600 plays from my referrals and I've made less than 20 cent's worth of commission that seems extremely low.
Our house edge is generally actually pretty high, and we have one of the highest affiliate sharing % of all bitcoin casinos.
Most of our players play for tiny amounts (less then $0.01). And it doesn't necessarily mean that if you have signed up a player, that he actually played for Bitcoin. Nevertheless, if that player comes back 6 months or one year from now and does play, you will still earn affiliate revenue off him.
We have affiliates who made 30 BTC +, from affiliate revenue alone. So it's very possible with the right marketing to profit from our affiliate scheme.
