Buying cryptocurrency through a peer-to-peer (P2P) system has become increasingly popular, especially for users seeking flexibility and local payment options. OKX’s C2C (Cash-to-Crypto) platform offers a secure, fast, and user-friendly way to purchase digital assets like USDT and BTC using fiat currencies such as HKD. Whether you're new to crypto or looking to refine your trading strategy, this comprehensive guide walks you through the entire OKX C2C buy process, from placing your first order to resolving common issues.
How to Buy Crypto on OKX C2C – Step-by-Step
Step 1: Access the C2C Buy Section
Open the OKX mobile app and navigate to the homepage. Tap on "Buy Crypto", then select "C2C Buy" to enter the trading interface.
👉 Start buying crypto securely with instant verification and real-time transactions.
Step 2: Choose Your Currency Pair and Merchant
On the C2C trading page, select your desired fiat currency (HKD) and the cryptocurrency you wish to purchase—common options include USDT or BTC.
You’ll see a list of available seller advertisements. Each listing shows:
- Exchange rate
- Payment methods accepted (e.g., FPS, bank transfer, cash in person)
- Seller reputation and transaction volume
Choose a seller that matches your preferred payment method and click "Buy" to proceed.
Step 3: Place Your Order
Enter the amount of HKD you want to spend or the quantity of crypto you’d like to receive. OKX automatically calculates the equivalent value.
One of the platform’s key advantages is zero trading fees—you’ll see a prompt like “0% fee to buy USDT” before confirming.
After entering the amount, tap "Buy USDT" (or your chosen asset) to generate the order.
Step 4: Complete Payment and Confirm
Once the order is created:
- You’ll be shown the seller’s payment details (bank account, FPS ID, etc.).
- Use your bank or e-wallet app to send the funds.
- After completing the transfer, return to the OKX app and click “I have paid”.
- Upload a screenshot of your payment confirmation as proof.
The seller will review your payment. Once confirmed, they’ll release the cryptocurrency to your funds wallet instantly.
⚠️ Never mark payment as complete unless you’ve actually transferred funds. Failing to pay after confirmation may result in account restrictions.
Frequently Asked Questions (FAQs)
Q1: How do I make a payment to the seller?
After placing an order, OKX displays the seller’s payment instructions. Use your preferred banking or wallet app (such as HSBC, Hang Seng, or AlipayHK) to complete the transfer. Ensure all details—account name, number, and reference—are accurate. After payment, return to the app and confirm via “I have paid”.
Q2: What are some tips for successful C2C payments?
To ensure smooth transactions:
- Pay before the countdown timer expires (usually 15–30 minutes).
- Use instant payment systems like FPS for faster processing.
- Only click “I have paid” after completing the actual transfer.
- Your payment account name must match your OKX registered name.
- Avoid including keywords like crypto, BTC, or USDT in payment notes—banks may flag these.

Q3: Can I cancel my C2C order?
Yes, you can cancel an order before making a payment by tapping “Cancel Order” in the order details. However:
- If you’ve already paid, do not cancel—this won’t refund your money.
- Instead, contact the seller via OKX Chat or submit a dispute if they fail to release crypto.
- Note: There are daily limits on cancellations. Exceeding them may temporarily restrict your trading ability.
Q4: What if my payment fails due to bank or wallet issues?
Since payments happen outside OKX, technical issues can occur. In such cases:
- Contact the seller via in-app chat to request an alternative payment method.
- If unresolved, cancel the order and choose another merchant with reliable channels.
Q5: When will I receive my crypto after paying?
You’ll receive crypto once:
- You complete the payment.
- Confirm it in-app with “I have paid”.
- The seller verifies receipt and clicks “Release Crypto”.
Funds arrive in your wallet immediately. If the seller is unresponsive, use the “Remind Seller” button and attach proof of payment.
Q6: What should I do if the seller doesn’t release crypto after I’ve paid?
First, verify:
- Your payment went through (keep a screenshot).
- You clicked “I have paid” before the deadline.
Then:
- Use “Remind Seller” and upload proof.
- Message them directly via OKX Chat.
- If no resolution, submit a dispute with evidence—OKX’s support team will mediate.
