You will face difficulties to make a withdrawal at 99% betting sites if you try to withdraw your deposited funds without placing any bets. You can't blame Cloudbet or any other casino for this. Casinos are really strict when it comes to money laundering activity. It just takes a few minutes to get the deposited funds in crypto casino account. You shouldn't access online casino if your decision changes within a few minutes gap. Your signature casino also has rollover requirements on deposit.
Well, what's the sense of making a deposit in a casino and immediately withdrawing money? People come to the casino to play and enjoy the game, not to withdraw money after making a deposit.
