IMO, it is worth trying even the wagering is 50x.

The bonus can be started after the real balance is out, and while we are winning we can ignore those bonus and just withdraw our real balance + the winning without any limitation from the wagering. Meanwhile, If you lose (let's say you are deposit 100$). I just can try all-in my bonus 50$ 4x times and try to turn out 800$.

If success, having a bankroll 800$ + with some wagering already finish around 8-10x. These one, kinda good for new player with less VIP rank cause our rank is low and mostly the cashback lose under 5-10%.
