Which % are acceptable on payouts

Quick question guys, new here and been only with one book but recently i hit well on this weeks NBA and before i cash out i wanted to ask whats the acceptable % on payouts? So i don't get bullied around and know the right % to pay. Appreciate it!

bitcoin is free at most books

Yeah that i know, i even setup coinbase and chainblock as mentionned in other threads

Thanks

Ok nvm apparently few free payouts a month is a thing now.
