Most likely your withdrawal has been reduced to match the deposit amount.
We would like to remind you that Visa/Mastercard is a payment system that allows only a refund of the deposited funds.
This means that withdrawal should be processed proportionally to the deposited sums.
You deposited via credit/debit card $10, then $20, then $30.
You will need to withdraw back to this card $10 + withdrawal fee, $20 + withdrawal fee, then $30 + withdrawal fee.
You can withdraw the amount exceeding the total amount of deposit made via card (your profit) to any electronic payment system available in your Personal Area.
If your balance has become less than your total card deposit amount during the trading, don't worry - you still will be able to withdraw your funds. In this case, one of your card deposits will be refunded partially.
