It's probably a restriction for their bonus, maybe just to wait 30 more days.
Just double check, i know it's a pain in the a$$, but is their place, their bonus policies, i rather just not get a bonus at all if i don't like their rules.
It is not a restriction, that's the way it is. I asked Carib and they said that the idea is that I can wager more to win more, but I can never get it. I told Carib I have gifts for all Carib staff but as soon as you ask for them you lose them. No response to my gift.
I think you can withdraw all funds down to the bonus amount (and not lose the bonus) and then bet the bonus amount. If you lose you've effectively earned your bonus.
If ANY withdrawal eliminates your bonus, then this concept totally sucks and borders on total deceit.
