The "Money In, Money Out" rule on BetMGM is a policy that requires users to withdraw funds using the same payment method that was used to deposit the funds. In other words, you cannot withdraw money from your BetMGM account using a payment method that you have not previously used to deposit funds into your account.
This rule is designed to protect against fraudulent activity and money laundering. It ensures that the person making the withdrawal is the same person who made the original deposit and that the funds are being sent to a legitimate account that is associated with the user.
For example, if you deposit funds into your BetMGM account using a credit card, you will need to withdraw those funds using the same credit card. Similarly, if you deposit funds using an e-wallet like PayPal, you will need to withdraw using the same e-wallet.
It's important to note that while the "Money In, Money Out" rule is a common practice among online gambling sites, it's always a good idea to read the terms and conditions of any site you're using to make sure you understand their specific policies and procedures for depositing and withdrawing funds.
