Yes bartercard players do get paid. They get the initial playing money as well as a win bonus. It isnt much though it depending on the team. Warriors and warriors development players in the bartercard cup get paid a little bit more. Players in each bartercard cup team r ranked and paid accordingly.
I have spokern to a few guys from the Bulls they don't get match payments of any sort but this year I think that CRL was going for 1000 dollars, and a voucher for a pair of boots or somthing like that.
