The reason you might be encountering this issue is that there might not be sufficient funds in your account to cover the full amount of the Risk-Free bet. To utilize a Risk-Free bet, you must use your own real money to place the bet. In the event that the bet doesn't go in your favor, don't worry — the funds will be gracefully returned to your account. Please ensure that your account has enough funds before attempting to use the Risk-Free bet. If you continue to experience difficulties, feel free to reach out to our support team for assistance.
