Why can’t I sell my Coinbase?

Cards are only able to be used for buys . At this time we are not able to transfer funds back to a card, so they cannot be used to sell digital currency.

If your account isn’t recognized as a trusted payment source , you may not be able to buy crypto and add cash on your account. Coinbase uses an automated system to help us protect the community and our site from fraud.

From the Coinbase mobile app: Tap Sell on the Home tab. Select the asset you want to sell and enter the amount. Tap Preview sell > Sell now to complete this action.
