Coinbase Wallet is a self-custody wallet, meaning Coinbase cannot directly transfer funds from it to your bank. To cash out from Coinbase Wallet, you need to:
1. Send your crypto from Coinbase Wallet to your Coinbase Exchange account.
2. Sell your crypto into fiat.
3. Withdraw the fiat to your bank or PayPal.
This extra step ensures your assets are converted properly before cashing out.
