Before troubleshooting, it helps to understand the normal cash-out process. On Coinbase.com, the general steps are: Sign in to your Coinbase account. Select Withdraw Cash from the home page. Enter the amount you want to withdraw. Choose the currency and withdrawal destination. Select Preview. Review the amount, fees, and destination. Select Withdraw Now. On the Coinbase mobile app, open Cash, select Withdraw, choose Withdraw Cash, enter the amount, select your destination, preview the withdrawal, and confirm it. If you only hold cryptocurrency, you usually need to sell it into your cash balance before withdrawing cash. Coinbase says crypto sales to your Coinbase cash balance are generally completed immediately, although existing holds can still prevent the money from being withdrawn.
