A subaffiliate is someone who you refer as a webmaster, whereas when you send someone to CR it’s as a player.
So by sending someone to RA, and they sign up under your affiliate tag, you earn 5% commission of their affiliate earnings. So, example, if they make $20000/month, you make 5% of that, = $1000, simply for referring them.
If you send people to CR, they are presented with our casinos rather than our affiliate program. So you would send players to CR so they will sign up at one of our casinos and play, where you then earn from their wagering.
I hope this helps. I’ve anything is unclear please let me know.
