Cut-out
You are right that casinos give more bonuses to the players with higher wagering and deposits record,, but also you should know that, casino also gives out bonus to those who are inactive or even first time visitor's to the casino.
Bonuses are meant to be a bait to keep a player on the casino even though they may not have the funds to make deposits at the moment, so for that bonus shouldn't be something that the player should treat like they real deposit money, the casino owns it and can decide to issue it any account they feel need to be keep active.
You're not wrong either. It's true casinos give welcome bonuses to new users and even non active users that have probably been away to encourage them to be active back again. I have experienced such where I suddenly stop using a certain casino and then I started receiving bonuses every now and then, I won some and lost some but it made me more active at the casino.
But even at that most casinos offer more of these bonuses to active users and they the more you deposit the more your bonus would be.
I would like to report one thing to Bitz team.
It seems that the site has a minor bug or a glitch with user account balance. To be clear, this issue did not exist weeks ago, and I only got it in my recent login sessions.
After logging in my account, I see my balance is empty. I thought something was wrong and I refreshed the page two times, then account balance shows accurately.
Again, previously this glitch did not exist so I think the team can take a look at it.
I think this is normal actually because It happens a lot with me. It could from the network or something so not really something to raise an alarm for, it happens with many online platforms.
