The withdrawal request shall be raised in the same funding method and of the same amount the deposit was made.
For eg:if a deposit of the amount of $100 was made using a bank card and $100 using a bank wire. Then, in this case, you can withdraw $50 using the bank card and $100 using the bank wire. You cannot initiate a withdrawal of more than $50 using the bank card or more than $100 using the bank wire.
In addition, when the withdrawn amount exceeds the amount deposited by a channel other than wire transfers (for example Instant Deposit via credit card or Moneybookers) the remaining withdrawal amount will be sent out by wire transfer.
