If you made a mistake when depositing money in BitMart, such as sending the wrong currency, using the wrong network, forgetting the memo/tag, or entering the wrong address, you may lose your money permanently. Therefore, it is very important to double-check your information before confirming your transaction. However, if you realize your mistake soon after making it, you may contact BitMart's customer support team at support@bitmart.com and provide them with your transaction details and proof of payment. They may be able to help you recover your money if it is possible and reasonable.
