How to Buy USDT on OKX
Purchasing USDT on OKX is simple and can be done in just a few steps. The platform supports multiple methods, including quick buy, peer-to-peer (P2P) trading, and institutional-grade bulk purchases. For beginners, we recommend starting with either the "Quick Buy" or "C2C" options.
Option 1: Use Quick Buy for Instant Transactions
The Quick Buy feature allows users to instantly purchase USDT using fiat currency (like Chinese yuan or USD). It’s ideal for small deposits and beginners who want immediate access to stablecoins.
Here’s how it works:
- Open the OKX app and go to the homepage.
- Tap on [C2C Buy Crypto].
- Select Quick Buy.
- Enter the amount you'd like to spend — for example, 1,000 CNY.
- The system will automatically calculate how much USDT you’ll receive (e.g., ~139.47 USDT).
- Alternatively, enter the desired quantity of USDT (e.g., 200 USDT), and the app will show the required payment (~1,434 CNY).
Once confirmed, the transaction processes quickly, and your USDT balance updates in real time.
Option 2: Trade via C2C (Peer-to-Peer)
For more control over pricing and payment methods, use the C2C (Customer-to-Customer) marketplace. This option connects buyers directly with verified sellers.
Steps to buy via C2C:
- On the same C2C Buy Crypto page, switch to the C2C tab.
- Filter offers by preferred payment method (e.g., Alipay, WeChat Pay, bank transfer) and desired amount.
Review seller profiles carefully. Prioritize sellers with:
- High completion rate (above 95%)
- Long-standing membership (e.g., registered over a year ago)
- Large number of completed trades
- Click [Buy USDT] next to your chosen offer.
- Enter the amount you wish to purchase.
- Click [0 Fee Purchase USDT] to create an order.
After placing the order:
- You’ll see the seller’s payment details.
- Leave the OKX app and complete the transfer using your selected method (e.g., mobile banking).
- Once transferred, return to OKX and click [I have paid].
- The seller will confirm receipt and release your USDT shortly.
This process typically takes just minutes if both parties act promptly.

How to Withdraw USDT from OKX
After purchasing USDT, you may want to transfer it to another wallet, exchange, or friend. Withdrawing crypto on OKX is straightforward but requires attention to detail — especially regarding network selection.
Follow these steps:
- Go to Assets at the bottom of the app.
- Tap Withdraw.
- Choose Cryptocurrency as the withdrawal type.
- Select USDT as the coin.
Choose where to send it:
- Internal Transfer: Send USDT to another OKX user — this is free and instant.
- External Wallet or Exchange: Send to an external destination.
For external withdrawals:
- Select the correct blockchain network (e.g., TRC20, ERC20, BEP20).
- Important: Ensure the receiving address supports the same network. For example, if you withdraw via TRC20, the recipient must accept TRC20-USDT.
- Incorrect network selection can result in permanent loss of funds.
Next:
- Paste the recipient's wallet or exchange deposit address.
- Enter the withdrawal amount.
- Confirm all details and submit.
Processing times vary by network but are usually within minutes.
Key Tips for Safe Withdrawals
- Always test with a small amount first when sending to a new address.
- Double-check addresses character-by-character.
- Never share private keys or withdrawal codes.
What Does T+1 Mean on OKX?
One common question among new users is: What does T+1 mean?
When you buy USDT or other digital assets with fiat currency (like CNY) on OKX, your funds are subject to a T+1 withdrawal restriction.
Understanding T+1
- T = Transaction day (the day you make the purchase)
- +1 = One calendar day later
This means that any USDT purchased with fiat cannot be withdrawn for 24 hours. For example:
- If you buy USDT at 6:30 PM on Monday, you won’t be able to withdraw it until 6:30 PM on Tuesday.
However, during this period:
✅ You can still trade your USDT for other cryptocurrencies (BTC, ETH, etc.)
❌ You cannot withdraw or transfer it off-platform
Why Does T+1 Exist?
T+1 is not unique to OKX — many major exchanges implement similar policies due to:
- Anti-money laundering (AML) regulations
- Fraud prevention
- Financial compliance requirements
By holding funds for 24 hours, exchanges can monitor transactions for suspicious activity and ensure buyer legitimacy, protecting both users and the platform.
While it may seem inconvenient, T+1 enhances overall security and helps maintain regulatory compliance in an evolving financial landscape.
Frequently Asked Questions (FAQ)
Q: Can I bypass the T+1 restriction on OKX?
A: No. T+1 is enforced automatically and cannot be skipped. However, you can still trade your newly bought USDT during this period.
Q: Is it safe to buy USDT through C2C on OKX?
A: Yes — as long as you follow best practices: only trade with high-reputation sellers, avoid deals outside the platform, and never mark payment as complete before sending money.
Q: Which network should I use when withdrawing USDT?
A: TRC20 is popular due to low fees and fast confirmations. However, always confirm which networks your receiving wallet or exchange supports before initiating a transfer.
Q: Are there fees for buying or withdrawing USDT on OKX?
A: C2C purchases have zero trading fees. Withdrawal fees vary by network — TRC20 usually has the lowest cost (~$1 or less).
Q: Can I send USDT from OKX to Binance or other exchanges?
A: Yes — just ensure both platforms support the same network (e.g., TRC20). Mismatched networks are the leading cause of lost funds.
Q: How do I verify my account on OKX?
A: Go to Account Settings > Identity Verification and follow the prompts. Verification increases withdrawal limits and unlocks advanced features.
