I think it should have never been possible to be able to make bets with balance that already was requested for payout. On bitdice when a coldwallet withdrawal is needed because hotwallet doesnt have enough. the funds are taken from the betting balance and player see's a notification that its got to be processed from cold by the admin. this way there's no stress no worries, just wait for admin glad too see u like bitdice slacky and had some amazing wins these days!
