Could you please elaborate on the process of withdrawing funds from Wemix? I'm interested in understanding the steps required to successfully transfer my funds from the platform. Specifically, I'd like to know if there are any prerequisites or verification steps I need to complete prior to withdrawal. Additionally, I'm curious about the turnaround time for the withdrawal to reflect in my account and any potential fees associated with the transaction. Could you also highlight any common issues or pitfalls that users might encounter during the withdrawal process?
