Exactly, Duelbits VIP program saved and never expires which makes small gambler level up their VIP status with just small bankroll. Consistency on small bets is the key to slowly climbing up the VIP level. Aside from the rakeback you can get that increases percentage every time you level up, the cash bonus per level is what makes Duelbits special because it generously gives back part of your wager that you accumulated while acquiring wager points.
Duelbits is the only casino that I’m using with this kind of cool VIP program format.
Their VIP program is ok, but personally it is not really different than other casinos. A lot of casinos give a (small) cash bonus when leveling up and also offer increased rakeback. I am a small gambler and even achieving the lowest tier is hard for me lol.
