Whether you're funding your crypto journey or preparing for trading, this step-by-step tutorial ensures a smooth and secure experience.
Why Buy USDT on OKX?
USDT (Tether) is one of the most widely used stablecoins, pegged 1:1 to the U.S. dollar. It serves as a bridge between traditional finance and digital assets, offering stability in a volatile market. OKX, a leading global cryptocurrency exchange, provides multiple fast and secure ways to acquire USDT — especially for users starting with fiat currencies like CNY or USD.

Step 1: Buy USDT Using Fiat Currency
To begin buying USDT on OKX, follow these simple steps:
Navigate to the C2C Buy Page
On the OKX homepage, click [C2C Buy]. You'll see three options:
- Quick Trade
- C2C (Peer-to-Peer)
- OTC (Over-the-Counter)
For small deposits under a few thousand dollars, Quick Trade is ideal due to its speed and simplicity.

Quick Trade Example:
Enter your desired amount — say, 1,000 CNY. The system will instantly calculate how much USDT you’ll receive (e.g., ~139.47 USDT). Alternatively, enter the number of USDT you want (like 200), and it will show the required CNY payment (~1,434 CNY).
After confirming the rate, proceed to payment via your preferred method — Alipay, WeChat Pay, bank transfer, etc.
Choose C2C for More Control
For greater flexibility or larger amounts, use the C2C marketplace.
Here’s what to do:
- Select your preferred payment method.
- Filter offers by price, volume, and completion rate.
Pick a reputable seller — look for:
- High trade volume
- Completion rate above 95%
- Account registration duration (longer is better)
Click [Buy USDT] and choose “0 fee purchase” if available.
Once the order is created:
- Read the seller’s instructions carefully (e.g., real-name transfer required).
- Click [Get Payment Details].
- Exit the platform and complete the bank transfer manually.
- Return to OKX and click [I have paid] to notify the seller.
The seller will release the USDT once they confirm receipt. Never release funds before seeing confirmation!
Step 2: Withdrawing Your USDT
After purchasing USDT, you may want to move it — either to another wallet, exchange, or friend.
Access the Withdrawal Section
Go to Assets > Withdraw > Cryptocurrency.
Select USDT as the coin type.
You have two main options:
- Internal Transfer: Send USDT to another OKX user — completely free and instant.
- External Transfer: Send to an external wallet or different exchange.
For external transfers:
- Choose the correct network (e.g., TRC20, ERC20, or BEP20).
- Enter the recipient's wallet address.
- Specify the amount.
- Confirm all details before submitting.
⚠️ Critical Tip: Always ensure the sending and receiving networks match. Sending USDT via TRC20 but depositing into an ERC20-only wallet will result in permanent loss.
Double-check every character of the address. Consider sending a small test transaction first when using a new wallet.
👉 Securely transfer your USDT with confidence using trusted methods.
Step 3: Understanding T+1 Withdrawal Restriction
One common confusion among new users is the T+1 rule.
What Does T+1 Mean?
After buying USDT with fiat (like CNY) on OKX, there’s a 24-hour withdrawal hold. This means:
- You can’t withdraw the purchased USDT within 24 hours.
- You can, however, trade it immediately — use it to buy BTC, ETH, or other cryptocurrencies.
For example: If you buy 150 USDT at 6:30 PM on Monday, you can only withdraw it after 6:30 PM on Tuesday.
Why Does T+1 Exist?
This policy is not unique to OKX — most regulated exchanges enforce similar rules due to:
- Anti-Money Laundering (AML) regulations
- Counter-terrorism financing compliance
- Protection against chargebacks and fraud
It helps verify that funds come from legitimate sources and protects both users and the platform.
While it may seem inconvenient, it enhances security and aligns with global financial standards.
Frequently Asked Questions (FAQ)
Q1: Can I bypass the T+1 restriction?
No. The T+1 rule applies automatically to all fiat-funded USDT purchases. However, you can still trade or stake those assets during the waiting period.
Q2: Is C2C trading safe on OKX?
Yes — as long as you follow best practices:
- Only trade with high-reputation sellers.
- Never communicate outside OKX’s chat system.
- Do not send money before placing the order.
The platform acts as escrow, holding the USDT until payment is confirmed.
Q3: Why did my USDT withdrawal fail?
Most failures occur due to network mismatch or incorrect wallet addresses. Always confirm:
- The recipient supports the selected network (TRC20, ERC20, etc.)
- The address is copied exactly without extra characters
Contact support only after verifying these details.
Q4: Are there fees for buying or withdrawing USDT?
OKX often offers zero fees for C2C trades, but spreads may vary slightly between sellers. Withdrawal fees depend on network congestion — TRC20 is typically cheapest (~$1 or less).
Q5: Can I sell USDT back to fiat?
Yes! Use the same C2C section and switch to “Sell USDT.” Choose a buyer, confirm payment method, and receive CNY directly to your bank or mobile wallet.
Q6: How long does a USDT withdrawal take?
Most transfers complete within 1–30 minutes depending on network traffic. TRC20 is usually fastest; ERC20 may take longer during peak Ethereum usage.
Final Tips for a Smooth Experience
- Always enable two-factor authentication (2FA) on your OKX account.
- Keep records of all transactions for tax or audit purposes.
- Use official OKX apps or website only — avoid phishing links.
- Start with small transactions until you’re confident in the process.
Whether you're preparing for deeper DeFi exploration or just securing stable value in crypto form, knowing how to buy and manage USDT effectively is essential.
