What should you check first?
- Check the account's verified residence and service provider.
- Inspect Payment Methods for the options actually offered to your account.
- Do not treat a globally advertised feature as confirmation of account access.
When should you stop?
Do not use another person's card or inaccurate residence information to unlock a feature.
When should you contact support?
Ask Gemini support to confirm the payment method and asset services enabled for your account. Provide the error message, not identity documents through unofficial channels.
Use the help centre linked from the exchange's official website. CoinBBank cannot access your account, approve a payment or recover a transfer.
