Main exchange
Coinbase
Coinbase documents ACH for US customers, buying crypto with a verified payment method, and sending supported assets to an external wallet.
- The confirmation screen—not this page—determines when ACH-funded assets become available to send. Coinbase shows that account-specific timing before you confirm.
- Coinbase's fee disclosure says simple buys charge a variable fee and include a spread, both shown in the preview. Coinbase Advanced uses the order book and does not include a spread.
- Exact services can be restricted by account, location, security review, or payment method.
- Confirm that the withdrawal flow says BTC on the Bitcoin network rather than a wrapped-BTC route.
