I have passed on the information about the Bitcoin withdrawal fees. As for promotions and contests, what kind of contests would you like to see?
I'm not aware of each promotion of wolf.bet as I'm not a regular gambler there. Wolf.bet has enough bonuses for it's VIP users. But I think you guys should add the monthly bonus to make the perfect combination of the VIP loyalty rewards. BTW, Wolf.bet should have kept the '7-day streak reward' for it's user. There is aslo a lack of promotions for the sports betting.
