We do not place any maximum amount on withdrawals made from a partner account, if you’ve earned it then you should have access to it whenever you want.
Simply follow the steps to withdraw from your partner account and it should prove successful, with no maximum amount set. There may be a maximum withdrawal amount set depending on the payment system chosen for the withdrawal action.
A minimum withdrawal of USD 1 is set as a guide, but there are no limitations to how much of your partner rewards you can withdraw or transfer to trading accounts in your Personal Area. However, there may be a minimum withdrawal amount set depending on the chosen payment system as well.
