In most cases I dont care how I will get my bonuses, because I am in casino to gamble at first place, but not to hunt bonuses. Sometimes I am even against unlockable bonuses, because they only trigger to continue gambling. Sometimes I dont even aware that I got a bonus, if the casino does not send me a notification and I would have to go to account and check if there is something for me. However, I like the level system when you achieve different wager stages and receive bonuses and cashback.
Yeah, you are right about that.
Unlockable bonuses can sometimes make a gambler do continuous gambling just to reach it which honestly I did before when I was trying to reach the Silver VIP at Stake.com. I was at 90% and just needed $1000 of wagered amount to unlock it. I spent a lot of dollars just to reach it which I thought I could get back but sadly, I lost more than what I received.
But I do like the other bonuses I received when weekly and monthly bonuses came because there I received an amount that tied all my losses and somehow I got a bit of profit thanks to it.
Still, I would not recommend doing this kind of thing. It's not enjoyable, it's honestly stressful.
