Hello there, I'm curious about Coinbase's fee policy when it comes to withdrawing USD. Specifically, I'd like to know if there's a fee associated with the process of withdrawing US dollars from my Coinbase account. It would be great if you could clarify this for me. Also, if there are any other important details or considerations I should be aware of regarding USD withdrawals on Coinbase, please feel free to share them. Thank you for your time and assistance.
