The good thing about "BK8" is how their Leaderboard Contest. They spread the rank and game, so example your rank is Bronze you will compete against Bronze member while most casinos don't filter the user based on their rank and game.
The idea of having competition among the same VIP level is good but it will be much better if the VIP program is not reset every month.
Since most of the leaderboard run in monthly basis, so basically all users will start the leaderboard contest with the same VIP level due to the reset.
I just did a quick reread the VIP program page, seems there are some updates that I have not seen before.
1st is about the withdrawal limit is based on user level and 2nd one is about the possibility to keep our VIP level.
Still, the requirement to be VIP is hard for me, as I need to make deposit of 50m IDR in a month to be a Bronze.
I believe I've never made a total deposit of that amount in any casino, so I can say that it will be impossible for me to be at least Bronze level.
Nothing else to hope except to see BK8 change the requirement to be VIP member, from the amount of deposit to the amount of wager.
