Cryptocurrency trading has become increasingly accessible, and platforms like OKX make it simple for both beginners and experienced users to buy and sell digital assets securely. Whether you're looking to purchase your first Bitcoin (BTC) or exchange USDT for fiat currency, OKX offers intuitive tools such as Quick Buy, C2C trading, and bulk transaction options to suit every need.
This guide walks you through the entire process of buying and selling crypto on OKX in 2025—step by step—with essential tips, security practices, and optimization strategies to ensure smooth, efficient transactions.
How to Buy Crypto on OKX
Buying cryptocurrency on OKX is a fast and secure process, especially when using the Quick Buy feature. This option allows users to instantly purchase popular coins like USDT, BTC, ETH, and more using local payment methods such as bank transfers, Alipay, or WeChat Pay.
Step-by-Step: Buying USDT on OKX
- Open the OKX App and go to the homepage.
- Tap [Quick Buy].
- Enter either the amount in CNY you’d like to spend or the number of USDT you want to buy.
- Select [Buy USDT] → [Confirm].
- Choose your preferred payment method (e.g., bank transfer, Alipay).
- Click [Confirm Purchase].
After placing your order, proceed to the next step:

- Open your mobile banking app, Alipay, or WeChat Pay, and complete the transfer to the seller’s provided account.
- Once payment is sent, tap [I've transferred, notify seller].
The seller will verify the payment. Upon confirmation, your purchased USDT will be released to your account. You can check your balance under the [Assets] tab.
Key Tips When Buying Crypto
- Bank statement verification: Some sellers may request a screenshot of your bank transaction history. This helps verify that the payment comes from a KYC-verified, real-name registered account—ensuring safety for both parties.
- Use real-name verified accounts only: All payments must come from a bank card linked to your identity via KYC.
- Transaction limits: Quick Buy supports transactions between 10 – 1,000,000 CNY per trade.
- Timing matters: For cross-bank transfers over 50,000 CNY outside business hours (after 17:00 to before 8:00 on weekdays or holidays), consider splitting payments to avoid delays.
- Order cancellation policy: You can cancel orders within the time limit, but frequent cancellations or failing to pay after clicking “I’ve paid” may affect your trading reputation and block further purchases for the day.
Alternative Ways to Buy
Besides Quick Buy, OKX also supports:
- C2C Trading: Browse offers from individual sellers and choose one that matches your preferred price and payment method.
- Bulk Trading (≥100,000 CNY): Use the [More Filters] option and select [Large Transaction] to find high-volume traders with better rates and dedicated support.
How to Sell Crypto on OKX
Selling digital assets like USDT or BTC for fiat currency is just as straightforward. With OKX’s user-friendly interface, you can convert your holdings into CNY quickly and securely.
Step-by-Step: Selling USDT on OKX
- From the OKX home screen, tap [Quick Buy].
- Switch to [Go Sell].
- Enter the amount of USDT you wish to sell or the target CNY amount.
- Select [Sell USDT] → [Confirm].
- Choose your preferred receiving method (bank account, Alipay, etc.).
- Complete the required Google Authenticator verification.
- Tap [Confirm Sale].
Now, wait for the buyer to make the payment.
Once the system shows that payment has been made ("Payment Confirmed"), log in to your online banking or mobile app to double-check that the funds have arrived in your account.
Only after confirming receipt should you click [Confirm Receipt] to release the cryptocurrency to the buyer.
Important Safety Reminders When Selling
- Never release coins prematurely: Always confirm that money is in your account before releasing crypto. Scammers may send fake payment proofs.
- Use dispute resolution if needed: If no payment arrives within the expected time, tap [File Complaint]. The platform will freeze the order and initiate an investigation with customer service.
- Double-check account details: Ensure all bank information entered is accurate and belongs to your verified identity.
Other Selling Options
Just like buying, you’re not limited to Quick Buy:
- Use C2C Sell mode to manually select buyers and negotiate terms.
- For large sales (≥100,000 CNY), apply the [Bulk Transaction] filter to connect with institutional-grade traders offering faster settlement and tighter spreads.
Frequently Asked Questions (FAQ)
Q: Is it safe to buy crypto via OKX’s C2C platform?
A: Yes. OKX uses an escrow system that holds the seller’s crypto until the buyer’s payment is confirmed. As long as you follow instructions and verify payments through official channels, transactions are secure.
Q: Why do some sellers ask for bank statement screenshots?
A: This is part of anti-fraud verification. It ensures the sender’s bank account is under their real name and reduces risks of chargebacks or money laundering—protecting both parties.
Q: Can I use someone else’s bank card to buy crypto?
A: No. All transactions must be conducted using a bank card registered under your own KYC-verified identity. Using third-party accounts violates platform rules and may result in fund freezes.
Q: What should I do if I accidentally release crypto before receiving payment?
A: Contact OKX customer support immediately. While recovery isn’t guaranteed, prompt reporting increases the chance of intervention—especially if fraud is detected.
Q: Are there fees for buying or selling on OKX?
A: The Quick Buy feature includes a small spread built into prices. However, registering via official channels can give you benefits like reduced trading fees or cashback incentives.
👉 Start trading with lower fees and enhanced security today—no experience needed.
Q: How long does it take for funds to arrive after selling crypto?
A: Most bank transfers complete within minutes during business hours. Off-hours or cross-bank transfers may take up to several hours. Always allow sufficient time and monitor your account closely.
