I've tried promoting sportsbook to my poker players off and on for over 2 years. You would think it would be a natural fit, but I have had little sucess. I recently added a sportbook topic section to my forum and have gotton a couple of
conversions for the superbowl... $320 cpa for a minimum $20 depsosit. The sports book obviously make more per player than the average poker room does per poker player.
I suspect its more of a trust issue here in the us, but I don't know for sure.
