Cryptocurrency has transformed the way we think about money, and Bitcoin stands at the forefront as the most recognized and valuable digital asset. For newcomers, navigating the world of crypto exchanges can seem daunting — but with the right guidance, buying and selling Bitcoin becomes a simple, secure, and rewarding experience.
This comprehensive tutorial walks you through every step of using the OKX exchange, one of the world’s leading platforms for trading cryptocurrencies, from account registration and identity verification to purchasing USDT, trading Bitcoin, and withdrawing funds. Whether you're a complete beginner or just new to OKX, this guide ensures a smooth onboarding process.
Step 1: Register Your OKX Account
To begin your journey, visit the official OKX website and start the registration process. You’ll need a valid email address (such as Gmail, Outlook, or 163) and your mobile number.
👉 Get started securely on one of the most trusted crypto platforms today.
Choose your country or region — users in China can select “China” and use a +86 phone number. After agreeing to the terms of service, enter your email and proceed. A verification code will be sent to your inbox; input it to continue.
Next, verify your phone number by entering the SMS code sent to your mobile device. Once both email and phone are confirmed, your account is successfully created.
🔐 Security Tip: Never share your login credentials or verification codes. OKX will never ask for these via email or chat.
Step 2: Download the OKX Mobile App
While OKX offers a web version, the mobile app provides enhanced functionality and security features. Android users can download directly from the official site by scanning the QR code. iOS users may need to switch to a non-mainland Apple ID to access the App Store version of OKX.
After downloading, log in with your registered account. The app interface is intuitive, offering quick access to trading, assets, and account settings.
Step 3: Complete Identity Verification (KYC)
Before trading or withdrawing funds, you must complete identity verification. This process enhances security and increases your transaction limits.
Navigate to your profile by tapping the menu icon (three lines or nine dots), then select “Identity Verification.” OKX offers multiple levels; completing Level 1 is sufficient for basic trading.
Select “China” as your country and “ID Card” as your document type. Upload clear photos of both sides of your ID, followed by a quick facial recognition check — simply follow the on-screen prompts to move your head slightly. Verification is usually completed within minutes.
✅ Why Verify? Verified accounts enjoy higher withdrawal limits, access to more financial products, and stronger protection against unauthorized access.
Step 4: Buy USDT via C2C Trading
USDT (Tether) is a stablecoin pegged to the U.S. dollar, making it ideal for entering the crypto market without volatility. On OKX, you can buy USDT using C2C (peer-to-peer) trading with local payment methods like Alipay.
From the homepage, tap [C2C Buy] > select USDT > enter the CNY amount you wish to purchase. Choose Alipay as your payment method and review available sellers.
Look for sellers with:
- High trade volume (over 300+ transactions)
- Trade completion rate above 98%
- Fast response time
Once you select a seller, click [Preview Order]. Copy their Alipay details and complete the transfer outside the app. After payment, return to OKX and click [I’ve paid]. Wait for the seller to confirm — once done, your USDT will appear in your funding account.
👉 Start trading with confidence using a platform trusted by millions worldwide.
⚠️ Safety Reminder: Always communicate through OKX’s internal chat. Never pay before placing an order, and never release USDT before confirming receipt of funds.
Step 5: Transfer Funds & Buy Bitcoin
To trade Bitcoin, transfer your USDT from the funding account to the trading account:
- Go to Assets > Transfer
- Select From: Funding Account, To: Trading Account
- Choose USDT, enter amount (or tap “Max”), then confirm
Now head to the Trade tab, search for BTC/USDT, and select the pair.
You have two main options:
- Limit Order: Set your desired price; the trade executes when market matches it.
- Market Order: Buy instantly at current market price.
For beginners, market order is simpler. Enter the amount of BTC or USDT you want to spend, ensure “Market Order” is selected, then tap [Buy BTC]. The purchase completes immediately.
Your Bitcoin will now appear under Assets > Trading Account.
Step 6: Sell Bitcoin & Withdraw Funds
When ready to cash out:
- Go to Trade > BTC/USDT
- Tap Sell, choose Market Order
- Enter amount (or select “All”) > [Sell BTC]
The proceeds (in USDT) go to your trading account. Transfer them back to your funding account via Assets > Transfer.
To withdraw money:
- Return to C2C Buy section
- Switch to Sell USDT
- Enter amount, choose Alipay
- Select a reputable buyer
- Confirm receipt of CNY before releasing USDT
Always double-check the buyer’s name matches the payment received.
