Cryptocurrency trading has become increasingly accessible, especially with user-friendly platforms like OKX offering secure and efficient C2C (Customer-to-Customer) trading options. This guide walks you through the complete process of buying USDT, conducting C2C transactions, purchasing Bitcoin, and withdrawing funds in CNY (Chinese Yuan)—all while ensuring safety, compliance, and optimal user experience.
Whether you're new to digital assets or expanding your trading strategy, understanding how OKX’s C2C system works is essential for smooth, low-risk transactions.
Understanding OKX C2C Trading
C2C trading on OKX allows users to directly buy or sell cryptocurrencies like USDT from other individuals, with OKX acting as a neutral arbitration platform. This model ensures trust between buyers and sellers without requiring them to rely solely on each other.
Here’s how it works:
- When a buyer places an order, the seller’s USDT is immediately locked in an escrow account controlled by OKX.
- The buyer then sends payment via bank transfer, Alipay, or WeChat Pay to the seller’s designated account.
- After confirming the payment, the buyer notifies OKX.
- OKX verifies the transaction with the seller before releasing the USDT to the buyer’s wallet.
This process mirrors how Alipay operates in e-commerce: funds are held securely until both parties fulfill their obligations. In this case, OKX controls the crypto (the "goods"), not the fiat money, minimizing fraud risk.

Step-by-Step: Registering Your OKX Account
Before trading, you’ll need an OKX account. Follow these steps:
- Visit the official OKX website and click "Sign Up".
- Use any valid email address (e.g., QQ, Gmail).
- Enter referral code 41322075 (if applicable) for potential fee benefits.
- Agree to terms and complete registration.
- Proceed with identity verification (KYC) using your mainland China ID—this is required for C2C access.
Once verified, you can begin trading immediately.
Downloading the OKX App & Completing Verification
The mobile app offers full functionality and is recommended for ease of use.
For Android Users:
- Open the OKX website and download the APK from the menu (three lines in the top-right corner).
For iOS Users:

- Log out of your current Apple ID in the App Store.
- Sign in with your foreign ID.
- Search for "OKX" or "欧易" — install the correct app (not ads).
After installation:
- Open the app and log in.
- Complete any pending identity verification prompts.
- Add your payment methods: bank card, Alipay, or WeChat Pay under [Profile] > [Payment Methods].

Pro Tip: Use Verified Sellers
Look for listings marked “Verification Required” or “Clean Fund Check”:
- These sellers require proof that your sending account hasn’t received recent deposits.
- Helps prevent involvement with illicit funds.
- Reduces risk of bank account freezes.
When selecting a buyer:
- Match their receiving account (e.g., Alipay) with one you control.
- Avoid using primary cards (salary, social security).
- Consider using a dedicated secondary card or Alipay account.
After receiving payment:
- Verify the transaction in your banking app—not just a screenshot!
- Only after confirmation tap [Confirm Receipt] on OKX.
Best Practices for Safe Withdrawals
To avoid complications:
- Never transfer crypto proceeds into personal or salary accounts.
- Don’t mix crypto income with regular finances—this can trigger cross-account freezes.
- For maximum safety: withdraw cash physically from ATMs using the card that received funds.
This creates a clear financial boundary and reduces legal exposure.
