To make a withdrawal request, log in to your Main account and go to My Account and then Withdraw in the navigation bar. Select the desired method, enter the required information and complete the request.
The first withdrawal for every calendar month will be free of charge. Every following withdrawal within the same month will be charged 2% (Minimum 5 EUR)
