I don't think they'll let customers to deposit and withdraw that easily. There should be some terms, like wagering deposit to claim it as a deposit meant for increasing VIP level because by simply making a deposit and withdrawal, their VIP system will be abused.
They have, and being used for all casino.
Deposit is always being made by 1x wagering same as other casino, As long you can finish 1x wagering should withdraw your fund. BTW, 1x wagering are quite easy especially for a player like @panjul or @roycilik.
They're playing slot and collecting a good waggering, so 1x waggering is quite easy.
