Cryptocurrency has become increasingly accessible, and platforms like OKX make it easier than ever to start your digital asset journey. If you're new to buying Bitcoin (BTC) or stablecoins like USDT, this comprehensive guide will walk you through the entire process—from account setup to your first purchase—safely and efficiently.
Whether you're looking to invest, trade, or simply explore the world of crypto, understanding how to use a trusted exchange like OKX is essential. This tutorial is tailored for beginners with no prior experience.
Step 1: Download the OKX App
To begin, download the OKX mobile app from the App Store or Google Play. If you're using an Apple ID registered outside certain regions, you may need to switch your region to access the app. For example, users in Taiwan should ensure their Apple ID is set to the Taiwan region.
Once downloaded, open the app and tap "Sign Up" to create a new account.

Step 2: Register Your Account
Use your email address or phone number to register—this ensures better security and recovery options. After entering your details, OKX will send a verification code to confirm your identity.
Upon successful registration, you’ll be prompted to set up a passkey, such as fingerprint or facial recognition. This biometric authentication adds an extra layer of protection, ensuring only you can access your account—even if someone knows your password.
A confirmation email will be sent to verify your inbox. Once confirmed, proceed to the next step.
Security Tip: Passkeys are stored locally on your device (e.g., iCloud Keychain or Google Cloud), so always use a personal, registered Apple or Google account—not a shared or purchased one.
Step 3: Complete Identity Verification (KYC)
For enhanced functionality and higher transaction limits, complete the Know Your Customer (KYC) process:
- Navigate to the verification section.
- Select China as your residence and ID card as the document type.
- Upload clear photos of both the front and back of your ID.
- Perform facial recognition by following on-screen prompts (e.g., blinking, turning your head).
This process ensures compliance and protects against fraud. Your documents are used solely for identity verification and are not shared externally.
Step 4: Set Up Advanced Security Features
After KYC, go to Security Center via the profile menu (tap the three dots in the top-left corner).
Enable Two-Factor Authentication (2FA) with Google Authenticator
- Download Google Authenticator from the App Store or Play Store (ensure it's published by Google).
- In OKX, select “Authenticator App” and copy the provided 16-digit secret key.
- Open Google Authenticator → tap "+" → choose "Enter setup key."
- Paste the key and assign it to your OKX account.
- A 6-digit code will generate every 30 seconds—this is your 2FA code.
⚠️ Important: Do not enable cloud sync for Google Authenticator. Keeping it offline prevents potential breaches via account recovery.
Return to OKX, enter the current 6-digit code, and complete setup. Now your account has top-tier protection with biometrics, email/phone verification, and 2FA.
Step 5: Buy USDT via C2C Trading
Now that your account is secure, it’s time to buy your first cryptocurrency.
- Tap "Buy Crypto" on the homepage.
- Choose C2C (peer-to-peer) trading.
- Select USDT as the cryptocurrency.
- Enter the amount in CNY (e.g., ¥500).
- Choose a payment method: Alipay, WeChat Pay, or bank transfer.
👉 Start buying USDT with ease using flexible payment options.
Choosing a Reliable Seller
Look for sellers with:
- High trade volume (e.g., over 30,000 completed trades)
- 99%+ positive feedback
- Fast response time
Select a reputable seller and click "Buy USDT". Confirm the amount—you’ll see exactly how much USDT you’ll receive (e.g., ~68.02 USDT for ¥500).
Click "Proceed with 0% fee", then transfer the money directly to the seller using Alipay.
After payment:
- Tap "I’ve Paid"
- Wait for the seller to confirm
- The USDT will be released from escrow to your wallet
If there’s an issue, use the chat function or file an appeal with payment proof.
Step 6: Transfer Funds & Trade Bitcoin
Once you have USDT in your wallet:
- Go to Assets → Transfer → Move USDT from Funding Account to Trading Account.
- Tap Trade → Select Spot Trading.
- Search for BTC/USDT pair.
You now have two order types:
✅ Limit Order
Set your desired price. The trade executes when market conditions match your limit.
✅ Market Order
Buy instantly at the current market price.
For beginners, market orders are simpler. Enter the amount of BTC or USDT, review fees, and confirm.
Your purchased Bitcoin will appear in your Spot Wallet under Assets.
Step 7: Sell or Withdraw Your Crypto
Need cash? Sell USDT back to CNY:
- Go to Buy Crypto → C2C → Sell USDT
- Choose a buyer with strong ratings
- Confirm amount and receive payment via your chosen method
Alternatively, explore Simple Earn for passive income:
- Deposit stablecoins like USDT
- Earn daily interest
- Withdraw anytime
Avoid futures or margin trading as a beginner—it involves leverage and higher risk.
