That's not even the strangest part
Would you, or anyone else, for that matter, expect a gambler who (allegedly) wagered close to 300k USD at just stake.com to come here and complain about wolf.bet not giving them some bonus for wagering 1 million dollars as well as advising everyone to stay away from it when they probably didn't wager a single dollar there? As I see it, that has nothing to do with rewards or their lack. Why not just keep on gambling at stake.com (or elsewhere) and enjoy whatever they are giving back? Seriously, what's the point?
I didn't look into it myself, but I read somewhere around here that the rakeback amounts to a smaller house edge, and it is a significant reduction down to 0.7% at the very outside if I remember correctly
