If your balance is positive it simply means that you are a good blackjack player and you have a chance to win a part of the real cash prize pool that is shared between the best blackjack players at the end of every month. Certainly, the higher your positive balance, the higher your chance to win a cash prize. See details about Competition Rules here.
If your balance is negative, the worst thing that happens is that you will not win a cash prize and that's all. You don't need to buy casino coins to continue playing blackjack online and you will not be charged for your negative balance. You will only know that you need to improve your blackjack gaming skills. It's a shame, but nothing more than that!
