Generally, you can can withdraw your wallet's base asset – for example, UNBNK for the Unbanked Card — from your account at any time by submitting a withdrawal request through your account dashboard.  On the main page of your dashboard, if this feature is available to you, there will be a button "withdraw" in the card section that will guide you through the process. Withdrawals generally happen quickly after your request has been initiated, security verified, and approved (pending ➩ approved ➩ completed). Please note that there is a 24 hour hold on withdrawals for security purposes before they are approved, and once approved they will usually complete within a few hours at most depending on the level of congestion that the asset network is facing at that time.
