This guide walks you through the complete process of buying crypto with your card on OKX, including step-by-step instructions, supported cards, fees, troubleshooting tips, and more.
Getting Started: How to Buy Crypto with a Card
To begin purchasing crypto with your debit or credit card, follow these streamlined steps:
- Log in to your OKX account
Open the OKX app or website and navigate to Buy > Buy crypto > Express Buy. - Choose the cryptocurrency you want to buy
Select from major coins like BTC, ETH, USDT, and others available in your region. - Enter the amount
You can input either the fiat amount (e.g., USD, EUR) you’d like to spend or the quantity of crypto you wish to purchase. Then, choose your preferred payment method. Add a new card (if needed)
If this is your first time, select Add card.- Enter your card details carefully—this includes the card number, expiration date, and CVV.
- Confirm that the card is in your name, as banks may require identity verification for security.
👉 Get started with a trusted platform to securely link your card and buy crypto instantly.
Note: Some card issuers apply multi-factor authentication (MFA), such as SMS codes or app-based approvals, to authorize transactions.
- Provide your billing address
Accurate billing information helps prevent payment rejections. After entering the details, tap Add card to complete setup. - Select your card and preview the purchase
Once added, choose the card from your payment options and click Next to review transaction details. - Confirm and buy
Finalize by tapping Buy. Your bank may send a one-time verification code via SMS or through its mobile app as part of 3-D Secure authentication. - Complete the transaction
Enter the code to confirm the purchase. Upon success, your fiat balance will be deducted, and the crypto will appear in your wallet instantly. - Review your order
You can either go back to the homepage or select Review details to see transaction history.
Supported Cards and Regional Availability
You can use Visa and Mastercard debit and credit cards from most countries worldwide. However, regional restrictions apply:
- Singapore and the United States: Only debit cards are currently supported.
- All other eligible regions generally support both debit and credit cards.
Ensure your card is issued by a financial institution that allows cryptocurrency purchases, as some banks may block such transactions by default.
Understanding Fees When Buying Crypto with Cards
Transaction fees vary based on your residence country and the currency used. Here's an overview of current rates:
- EUR: 1.99%
- HKD: 2.49%
- USD: 2.49%
- SGD: 2.49%
- AUD: 1.50%
Note: These fees are subject to change based on market conditions and regulatory requirements.
Why Are Credit Card Fees Sometimes Higher?
While the platform fee remains transparent, some banks treat crypto purchases as cash advances, which can incur additional charges or higher interest rates. These are imposed by your card issuer—not by OKX.
👉 Avoid surprise fees by verifying your bank’s policy before making a purchase.
We recommend contacting your bank directly to understand how they classify cryptocurrency transactions and whether extra costs apply.
Common Issues & Troubleshooting
Even with a smooth process, occasional hiccups may occur. Below are common problems and how to resolve them.
Why Can’t I Add My Card?
- Double-check all card details: number, expiry date, CVV, and billing address.
- Ensure your card supports international transactions if purchasing in a foreign currency.
- Some cards require pre-authorization through a small microcharge or 3-D Secure authentication.
- If issues persist, contact customer support for assistance.
Why Is My Transaction Failing?
Possible reasons include:
- Expired card
- Insufficient funds
- Bank blocking the transaction
- Incorrect verification code
If retries fail, reach out to your bank or platform support to investigate.
Where Does the Verification Code Come From?
The code is sent by your card-issuing bank during the 3-D Secure verification process. It ensures you’re the legitimate cardholder and enhances transaction security.
Simply enter the code when prompted to complete your purchase.
