Cryptocurrency trading has become increasingly accessible, and one of the most popular ways to enter the market is by purchasing USDT (Tether) — a stablecoin pegged to the U.S. dollar. Among the leading platforms that support this process is OKX, known for its security, user-friendly interface, and wide range of trading options.
This comprehensive guide walks you through every step of buying USDT on OKX — from account registration and identity verification to funding your account and executing your first trade — all within minutes.
1. Register an OKX Account
To begin trading on OKX, you must first create an account. The process is quick, secure, and straightforward.
👉 Start your crypto journey with a trusted global exchange — sign up today.
Steps to Register:
- Visit the Official Website: Open your browser and navigate directly to the official OKX website. Always double-check the URL to avoid phishing sites.
- Click “Register”: Located in the top-right corner, this button opens the sign-up form.
- Choose Your Method: You can register using either your email address or mobile number — pick whichever is more convenient for receiving verification codes.
- Set a Strong Password: Create a password with at least 8 characters, combining uppercase and lowercase letters, numbers, and special symbols (e.g.,
!@#$%^&*). - Complete CAPTCHA Verification: Follow the on-screen instructions to verify you're not a bot, typically via image recognition or puzzle-solving.
- Accept Terms & Conditions: Read and agree to OKX’s privacy policy and service terms before proceeding.
- Finalize Registration: Click “Sign Up” to complete the process.
Once registered, you’ll gain access to a basic account. However, full functionality requires completing identity verification (KYC).
2. Complete Identity Verification (KYC)
KYC (Know Your Customer) is a mandatory process designed to enhance security, prevent fraud, and comply with global anti-money laundering (AML) regulations.
Why Verify?
- Unlock higher withdrawal limits
- Access advanced trading features
- Improve account protection
How to Complete KYC:
- Log In to your OKX account.
- Navigate to Account Settings > Identity Verification.
- Select Verification Level: OKX offers tiered verification (e.g., Level 1, Level 2), each unlocking progressively greater privileges.
- Enter Personal Information: Provide your legal name, date of birth, nationality, and residential address — ensure accuracy.
- Upload ID Documents: Submit a clear photo or scan of your government-issued ID (passport, driver’s license, or national ID card). Both front and back may be required.
- Perform Facial Recognition: Use your device’s camera to complete a live face scan under good lighting conditions.
- Wait for Review: Processing usually takes minutes to hours. You’ll receive a notification once approved.
With KYC complete, your account is now fully enabled for trading and withdrawals.
3. Deposit Cryptocurrency
Before buying USDT, you need funds in your OKX wallet. While you can buy USDT directly with fiat, depositing existing crypto like BTC or ETH gives you flexibility.
How to Deposit:
- Go to Assets > Deposit in your dashboard.
- Select the Cryptocurrency you wish to deposit (e.g., BTC, ETH).
Choose the Correct Network: This is critical. For example:
- Use ERC-20 for Ethereum-based tokens
- Use TRC-20 for lower-fee Tether transfers
- Match the network used by your sending wallet
- Copy the Deposit Address: A unique string of characters or QR code will appear — copy it carefully.
- Send Funds: From your external wallet or exchange, initiate a transfer using the copied address and correct network.
Wait for Confirmations:
- BTC: 3–6 block confirmations (~10–60 minutes)
- ETH: 12–30 confirmations (~5–15 minutes)
Once confirmed, the balance appears in your OKX account.
⚠️ Never send funds across mismatched networks — doing so may result in permanent loss.
4. Buy USDT Using Your Deposited Crypto
Now that your account is funded, you’re ready to convert your cryptocurrency into USDT.
OKX supports multiple methods:
Option A: Spot Trading
Ideal for users who want control over price and timing.
- Go to Trade > Spot Trading.
- Search for the trading pair: e.g., BTC/USDT or ETH/USDT.
Choose Order Type:
- Limit Order: Set your desired price; order executes when market reaches it.
- Market Order: Instantly buys at current best price — fast but less precise.
- Enter amount (in BTC or USDT value).
- Click Buy USDT and confirm.
Your purchased USDT will appear in your spot wallet instantly upon execution.
Option B: P2P (Peer-to-Peer) Trading
Buy USDT directly with fiat currency (like CNY, USD) from verified sellers.
- Navigate to Trade > P2P.
- Select Buy USDT.
- Choose preferred payment method: bank transfer, Alipay, WeChat Pay, etc.
- Pick a reputable seller (check ratings and completion rate).
- Enter amount → Click “Buy USDT” → Make payment as instructed.
- After seller confirms receipt, USDT is released to your account.
This method avoids bank restrictions and offers flexible payment options.

For beginners seeking simplicity.
👉 Skip the complexity — instantly purchase USDT with just a few clicks.
- Use the "Buy Crypto" section
- Select USDT
- Choose payment method (crypto or fiat)
