To prevent Howl from being used for trading/exchanging currencies and possible manipulation, users are required to bet 100% of their deposit before withdrawing. We understand this can be frustrating and affect regular users, however to keep our services running, it is a required safety measure.
So if for example, you deposit $10.00, you will be required to bet a minimum $10.00 before being able to withdraw. You can bet your deposit amount in any way you wish, whether that is in one big bet of $10.00, or many small bets, such as 100x $0.10 bets. After that, any winnings you may have, you will be able to withdraw them. Having free coins in your balance will need to wager them too along with your deposit before you are able to withdraw.
