Purchasing USDT (Tether) is often the first step for investors entering the cryptocurrency market. As a stablecoin pegged 1:1 to the U.S. dollar, USDT offers stability in an otherwise volatile digital asset landscape. Among the top platforms facilitating this process is OKX, one of the world’s leading cryptocurrency exchanges by trading volume. With its user-friendly interface, fast transaction processing, and support for multiple payment methods—including Alipay—OKX makes it easy for both beginners and experienced traders to buy, sell, and trade USDT seamlessly.
This comprehensive guide walks you through every step of buying USDT on OKX, from account setup to completing your first C2C (peer-to-peer) transaction. We’ll also explore what USDT is, how it works, and why it plays a crucial role in crypto trading strategies.
What Is USDT and Why Use It?
USDT (Tether) is a stablecoin issued by Tether Limited, designed to mirror the value of the U.S. dollar. Each USDT token is backed by reserves consisting of cash and cash equivalents, ensuring a 1:1 redemption rate with USD. This stability makes USDT ideal for:
- Preserving value during market downturns
- Facilitating quick trades between different cryptocurrencies
- Reducing exposure to volatility while remaining within the crypto ecosystem
- Withdrawing profits safely by converting volatile assets into a stable digital form
Because of these benefits, USDT has become one of the most widely used digital currencies across global exchanges.

Step-by-Step: How to Buy USDT on OKX
Step 1: Register and Log In to Your OKX Account
Before purchasing USDT, you need to create an account on OKX. Visit the official website and choose your region (domestic or international). Complete registration using your email or phone number and set up two-factor authentication (2FA) for enhanced security.
🔐 Tip: Always use strong passwords and enable Google Authenticator for added protection.
Once registered, log in to your OKX dashboard.
Step 2: Navigate to the C2C Trading Section
From the homepage, go to the "Buy Crypto" section and select C2C Trading. Here, you’ll find a list of verified sellers offering USDT in exchange for fiat currencies like Chinese yuan (CNY), with various payment methods including Alipay, WeChat Pay, and bank transfers.
Step 3: Select a Seller and Place Your Order
Browse through available offers and pay attention to:
- USDT price per unit (may vary slightly between sellers)
- Seller rating and transaction history
- Preferred payment method
Choose a seller that matches your preferences, enter the amount of CNY you'd like to spend (or specify how much USDT you want), and click "Buy USDT".
Step 4: Complete Payment and Confirm Transaction
After placing your order:
- You’ll be directed to a secure payment page.
- Follow the instructions to transfer funds directly to the seller’s designated account via your chosen method.
- Once payment is complete, click “I have paid” to notify the seller.
- The seller will then release the USDT to your OKX wallet.
⚠️ Important: Do not mark payment as complete until the actual transfer is finished. Transactions are time-sensitive—failure to complete within the allotted window may result in cancellation.

Is USDT Legal in China?
As of current regulations, China does not recognize any cryptocurrency—including USDT—as legal tender. In 2017, Chinese authorities banned initial coin offerings (ICOs) and shut down domestic crypto exchanges. While personal ownership isn’t explicitly illegal, trading or facilitating transactions involving virtual currencies is restricted.
However, peer-to-peer (P2P) trading through international platforms like OKX remains accessible. Many users in China continue to trade USDT via C2C markets without interference—though such activities operate in a regulatory gray area and lack legal protection.
In short:
🟡 USDT trading in China is neither fully legal nor outright illegal—but it comes with risks and no official safeguards.
Understanding Tether’s Reserve Model
Transparency has been a key concern for stablecoins, especially regarding whether they’re truly backed 1:1 by reserves. According to Tether’s official disclosures:
- Every USDT in circulation is supported by equivalent assets held in reserve.
- Reserves include cash, cash equivalents, short-term deposits, and other low-risk instruments.
- Independent audits have confirmed partial backing, though full real-time transparency remains limited.
Users can view summary reserve reports published monthly on Tether’s website to verify financial health.
This model helps maintain confidence in USDT’s stability—even during periods of high market stress.
