Step-by-Step: How to Buy USDT on OKX
1. Register an Account
To begin, visit the official OKX website and create an account:
- Enter your email address.
- Set a strong password.
- Complete email verification by entering the code sent to your inbox.
- Add a mobile number for two-factor authentication (2FA).
⚠️ Tip: If you're using a referral link from a trusted source, the invite code may auto-fill. This can unlock benefits like 20% permanent fee reduction on all trades.
When selecting your region, choose "China" if you plan to verify with a Chinese ID. Your selected country will determine which identity documents are accepted during KYC.
2. Complete Identity Verification
Before buying or selling, complete Level 1 KYC verification:
- Upload a clear photo of your government-issued ID (e.g., Chinese ID card).
- Take a live selfie for facial recognition.
This process usually takes just minutes and unlocks higher trading limits and enhanced security features.
3. Access C2C Buy Section
Once logged in:
- Go to the homepage.
- Click [C2C Buy] — located prominently in the main menu.
- You’ll see three options: C2C Buy, Quick Trade, and Large Orders. We recommend C2C Buy for full control over pricing and counterparty selection.
4. Place Your First USDT Purchase
Let’s say you want to buy 100 RMB worth of USDT:
- Click [Amount] and enter
100. - Press [Confirm].
The system displays all available sellers matching your amount. At small amounts like this, avoid filtering by payment method — doing so may lead to inflated prices.
Instead, focus on seller reputation:
- High trade volume
- Above 99% completion rate
- Long registration history (preferably over 6 months)
For example, look for sellers like “Qingtian Trading,” registered in early 2023 — over a year ago — with thousands of completed trades.
Click [Buy] next to your chosen seller.
5. Complete Payment and Confirm Transaction
On the order page:
- Review any seller-specific requirements (e.g., real-name match).
- Click [Get Payment Details] to reveal their Alipay or bank account.
- Copy the details and complete the transfer via your own Alipay app.
After payment:
- Return to OKX.
- Click [I have paid].
- Wait for the seller to confirm receipt.
Once confirmed, your USDT will appear in your Funding Account.
6. Transfer USDT to Trading Account
To use USDT for trading other cryptocurrencies:
- Click [Transfer].
Select:
- From: Funding Account
- To: Trading Account
- Asset: USDT
- Amount: Enter desired quantity
- Confirm.
Your USDT is now ready for spot, margin, or futures trading.

How to Sell USDT for CNY on OKX
Selling USDT requires extra caution — especially regarding fund safety and anti-fraud checks.
1. Move USDT from Trading to Funding Account
Before selling:
- Navigate to [Assets] > [Transfer]
- Transfer USDT from Trading Account → Funding Account
Only funds in the funding account can be sold via C2C.
2. Switch to “Sell” Mode
On the C2C page:
- Change the tab from Buy to Sell.
- Enter the amount of USDT you wish to sell (e.g., 14 USDT).
3. Filter Sellers by Payment Method
When cashing out, prioritize security:
- Select Bank Card as the payment method.
- Avoid using salary or social security cards.
- Consider opening a dedicated bank account for crypto transactions.
- Recommended banks: China Merchants Bank, Bank of China — avoid Agricultural Bank due to stricter monitoring.
4. Choose a Reputable Buyer
Use these three criteria:
- ✅ High trade volume (10,000+ completed orders)
- ✅ Completion rate above 99%
- ✅ Registration date older than 6 months
Click on potential buyers to view their profile — for instance, a seller registered on June 28, 2023, meets the longevity requirement.

Advanced Safety Tip: Use Diamond-Rated Sellers in Large Orders
OKX has introduced a new feature: "Large Orders" section, identifiable by purple diamond icons next to certain sellers (vs blue stars in standard C2C).
These Diamond Merchants are elite traders with:
- Exceptional reputation
- Massive transaction volume
- Higher capital reserves
When selling large amounts of USDT:
- Go to [Large Orders]
- Contact a diamond-rated seller
- Request they pause transactions for 3–5 days after depositing funds
Why? Because illicit funds move quickly — "dirty money" rarely stays in an account longer than 24 hours. By waiting, you reduce the risk of receiving tainted funds that could trigger bank freezes or investigations.
Ask the seller to provide a bank statement screenshot showing funds held for several days — this adds another layer of trust.
Final Tips for Safe USDT Transactions
- ❌ Never trade outside OKX (e.g., Telegram groups or YouTube comments promising “high buy price”).
- ✅ Always confirm the sender’s real name matches their account before releasing USDT.
- 🔐 Enable two-factor authentication (2FA) and use a strong password.
- 📊 Monitor market rates — unusually high or low prices often signal scams.
