I would first check the exact affiliate conditions and how they participate you on the earnings. There are two models that are very different: 1) you get a share of the stakes, no matter if the bet wins or loses, or 2) you only get a share if the bets are lost, if the bets are won you get a credit deduction, which can lead to a negative balance. I recently opened a thread on this topic where I described my experiences with the model of negative balance/carryover (but it is a different betting provider than yours).
