All things happened but you should not regret it because you will still have a chance to win big in the next days. At least, you losses can bring you closer to reached VIP 4. That is not easy to do that and you are one of the lucky people who almost reached VIP 4.
Afaik VIP can be attain with not that high wager. It’s better to play house games like dice to level up quickly with minimal loss compared to slot.
It's hard to wager a lot with slots, especially if someone plays with minimal bets. Buying bonuses like crazy is something else, but that is sooo risky and one needs to have a huge balance & a lot of luck to endure the process. Losing a +10 bonus buy in a row happens all the time...
Wagering on in-house games is different. I like Plinko, Limbo, and Keno sometimes... pretty fast gameplay, occasionally raising stakes, and pretty quickly we can wager a lot. Of course, that kind of playing is always risky and it mostly comes with some losses. I have rarely been in profit after trying to wager a lot in a short time.
