One the reason.
Why, I really hate claiming or using "Deposit or some this type promotion". While we are on big win, they are can easily created any reason with this case. Best way always using raw cash, so they're not gonna to questioned the winning money especially from Live Games.
This the major reason why I don't always claim promotions and bonuses, there always have some hidden conditions that will make all your efforts useless when you make a big winning. So the best thing to do when you want to wager a bigger amount for a potential big winning one need to make a personal deposit and should not use bonuses.
True, I would have loved to ask for promotions, but I have repeatedly had problems not obtaining them despite the full respect of the terms and conditions. It is better to deposit and bet without claiming a bonus.
