OKX, one of the world’s leading cryptocurrency exchanges, offers a seamless and secure platform for users to trade digital assets using fiat currency through its Buy/Sell feature.

🔐 Step 1: Complete Your Account Setup
Before buying or selling crypto on OKX, you must complete four essential security and identity settings:
1.1 KYC Verification (Know Your Customer)
To enhance security and unlock higher trading limits, complete your KYC verification:
- On Mobile App: Tap the profile icon → [Identity Verification] → Follow prompts to complete Level 1 (Basic), Level 2 (Advanced), and Level 3 (Video Verification).
On Web: Click the top-right icon → [Identity Verification] → Complete Level 1 and 2.

1.2 Bind Your Phone Number
Ensure your account is protected by two-factor authentication:
- Go to Security Settings → Phone Verification

1.3 Set Up a Fund Password
This password is required every time you withdraw funds or confirm sensitive transactions:
- Navigate to Security Settings → Fund Password
- Create a strong, unique password
Use this section to also enable additional protections like:
- Login password change
- Google Authenticator
- Anti-phishing code

- WeChat Pay
How to add:

🪙 Step 3: How to Sell Cryptocurrency on OKX
Selling crypto works similarly but reverses the flow—you send crypto and receive fiat.
Example: Selling USDT
On Mobile:
- Go to [Buy Crypto] → [Quick Buy] → [Sell]
- Enter amount of USDT to sell
- Select payout method (bank, Alipay, WeChat)
- Tap [Confirm Sell]
Wait for buyer’s payment:
- Once “Payment Received” lights up, log in to your bank or payment app to verify funds have arrived
- Only after confirming receipt, enter your fund password and click [Confirm Receipt]
⚠️ Warning:
- Delayed release of crypto after payment confirmation affects your average release time rating
- Never release assets without verifying the transfer in your personal banking interface
- If no payment arrives within the deadline, tap [File Complaint] → Support team will intervene
On Web:
- Click [Buy Crypto] → [Sell]
- Choose crypto (e.g., USDT), enter amount
- Select payment method → [Sell USDT]
- After buyer pays, confirm receipt in your bank → Return to OKX → [Confirm Receipt]
For larger trades (≥100,000 CNY), use the OTC or C2C marketplace to find high-volume buyers with competitive rates.
📋 Step 4: Track Your Trade History
Stay on top of your transactions by reviewing your order history.
On Mobile:
- Tap [Buy Crypto] → [Orders]
- Filter by: Pending / Completed / Canceled
Use the filter icon (top-right) to sort by date, type, or status.
On Web:

- Use filters to manage active and past trades
Monitoring your history helps maintain trust and improves future merchant matching.
🔍 Frequently Asked Questions (FAQ)
Q1: Why do I need KYC to buy crypto?
A: KYC ensures compliance with global regulations and enhances platform security. Higher verification levels unlock better trading rates and access to premium features like OTC desks.
Q2: Can I use someone else’s bank account to trade?
A: No. All payment methods must be under your real name and linked to your verified identity. Using third-party accounts violates OKX policies and may result in account restrictions.
Q3: What should I do if I accidentally marked a transfer as complete before sending?
A: This action can damage your reputation. Contact customer support immediately to explain the situation and avoid being flagged for fraudulent behavior.
Q4: How long does it take for a buyer to pay?
A: Buyers typically have 15–30 minutes to complete payment. If no funds arrive within the timeframe, use the [File Complaint] option for assistance.
Q5: Is it safe to trade on OKX’s C2C platform?
A: Yes. OKX uses an escrow system—your crypto is held securely until the buyer’s payment is confirmed. Always verify payments through your own banking channel before releasing funds.
Q6: Can I trade without setting a fund password?
A: No. A fund password is mandatory for all withdrawals and sell transactions to protect your assets from unauthorized access.
🎯 Final Tips for Successful Trading
- Always double-check payment details before transferring money.
- Avoid mentioning crypto-related terms in transfer notes to prevent bank flags.
- Use the C2C marketplace to compare prices and choose reliable traders with high completion rates.
