The pre-monthly bonus has no effect on the last wager right? I mean all users get the same bonus based on account level?
Then the monthly bonus might be a little different because there is a net loss calculation.
Yep, pre-monthly bonus has no connection with the wager. It depends on our VIP rank only. However, your bonus amount will be lowered if you don't make deposits or wager a decent amount for a few months.
I can confirm this, my pre and post monthly bonus is lowered already. It used to be $25 for me as Platinum II user. My last two bonuses (post monthly on Aug and this month pre monthly) is no longer $25 but $17. Yes it must be because I have reduced my gambling activity a lot since months ago, so I will not complain about it.
