Yes, it is possible to withdraw funds from a betting site to Trustly. To do so, users must first log in and select Trustly as their preferred payment method. Then, they must enter the amount of money they would like to deposit before being redirected to the Trustly website, where they must choose their bank from the supplied list. Lastly, users should be redirected to their online bank, where they can authorise the payment and have the funds available in their betting account. It is important to note that withdrawal times may vary depending on which bookmaker is being used, and there are filters available for selecting bookies with faster withdrawal times.
