If Coinbase closes your account for violating the user agreement violations, you'll be prompted to withdraw your funds upon signing in.
Coinbase does not provide conversion services for closed accounts. You can withdraw from your cash balance to a verified bank account, or send crypto off Coinbase.
Review Escheatment and unclaimed funds for information on how long your funds will be available for withdrawal.
Send crypto off Coinbase
To send crypto, you need an external address from a third-party wallet provider. Here are some options:
Bitcoin: https://www.bitcoin.org/
Ethereum: https://www.myetherwallet.com/
Withdraw cash balance
You can immediately withdraw your cash balance to a previously verified bank account. If you don’t have a verified bank account, gather your banking details and contact support.
Once all funds are successfully withdrawn, your account will be closed.
