To coinbase close account, log in and go to Settings, then select Close Account at the bottom of the page. Ensure you’ve withdrawn all funds, as accounts with a balance cannot be closed. Follow the prompts to confirm the closure. If you experience any issues during the process, contact Coinbase support for assistance. Keep in mind that account closure is permanent, so ensure you no longer need access before proceeding. https://deficryptowallets.com/coinbase-account-closed-without-warning/
