Step 1: Access the OKX Website and Log In
Open your browser and navigate to the official OKX website. If you're new, complete the registration process by providing your email or phone number and setting up two-factor authentication (2FA) for added security.
Once registered, log in to your account.
Step 2: Navigate to the C2C Trading Section
After logging in:
- Click on "Buy Crypto" from the main menu.
- Select "C2C Trading".
- Choose USDT as the cryptocurrency you want to buy.
You’ll now see a list of verified sellers offering USDT at different prices and payment methods.
Step 3: Select a Seller and Place Your Order
Review each seller’s:
- USDT price per unit
- Minimum and maximum transaction limits
- Payment methods accepted (e.g., Alipay, WeChat, bank transfer)
- Trade completion rate and number of completed orders
Choose a reliable seller with favorable terms. Enter the amount of CNY you'd like to spend or the quantity of USDT you wish to buy. The system will automatically calculate the corresponding value.
Click "Buy USDT" to proceed.
Step 4: Complete Payment and Confirm Transaction
After placing your order:
- You'll be directed to an order confirmation page.
- Follow the instructions to send payment directly to the seller’s designated account (via Alipay, bank transfer, etc.).
- Once payment is made, click "I have paid" to notify the seller.
The seller will then release the USDT to your wallet upon verifying the payment. This process typically takes just a few minutes.
⚠️ Always communicate through OKX’s internal messaging system. Never share personal information or make payments outside the platform.
What Is USDT?
USDT (Tether) is a stablecoin pegged 1:1 to the U.S. dollar, issued by Tether Limited. Each USDT token is backed by equivalent reserves in cash and cash-like assets, ensuring price stability compared to volatile cryptocurrencies like Bitcoin or Ethereum.
Key Features of USDT:
- Stability: Maintains a consistent value of approximately $1 USD.
- Transparency: Tether publishes regular reserve attestations.
- Interoperability: Available on multiple blockchains (e.g., Ethereum, Tron, Solana).
- Liquidity: One of the most widely traded cryptocurrencies globally.
USDT serves as a digital dollar equivalent in the crypto ecosystem, making it ideal for:
- Hedging against market volatility
- Facilitating quick trades between assets
- Transferring value across exchanges without converting to fiat

Is USDT Legal in China?
As of current regulations, China does not recognize any cryptocurrency as legal tender, including USDT. In 2017, Chinese authorities banned initial coin offerings (ICOs) and shut down domestic crypto exchanges. While peer-to-peer trading isn’t explicitly illegal, financial institutions are prohibited from providing services related to cryptocurrency transactions.
In practice:
- Individuals can still hold and trade USDT via international platforms like OKX.
- There is no legal protection for losses incurred during trading.
- Transactions must comply with anti-money laundering (AML) rules.
So while owning or using USDT isn't technically illegal for personal use, it operates in a regulatory gray area — neither fully legal nor explicitly prohibited.
Why Should You Use USDT?
1. Market Volatility Protection
During periods of high market uncertainty, traders convert their holdings into USDT to preserve capital without exiting the crypto ecosystem.
2. Fast Cross-Exchange Transfers
Instead of withdrawing funds to a bank account, you can transfer USDT between exchanges quickly and at low cost.
3. Easier Entry and Exit Points
Newcomers can buy USDT with local currency and then swap it for other cryptocurrencies like BTC or ETH. Similarly, profits can be converted back into USDT before cashing out.
4. Global Accessibility
Unlike traditional banking systems, USDT can be sent anywhere in the world within minutes, bypassing SWIFT delays and high fees.
