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 new to the world of crypto or looking to refine your trading process, this guide walks you through everything you need to know about purchasing and selling coins on OKX — from initial steps to key tips that ensure smooth, secure transactions.
What Does It Mean to Buy Crypto?
At its core, buying cryptocurrency means exchanging fiat currency — such as Chinese Yuan (CNY) or US Dollars (USD) — for digital assets like Bitcoin (BTC) or Tether (USDT). This is typically done through a trusted exchange platform that connects buyers with sellers in a secure environment.
One of the most reliable platforms for this is OKX, known for its user-friendly interface, strong security measures, and fast transaction processing. With just a few taps, you can convert your local currency into crypto and begin building your digital portfolio.

How to Buy USDT on OKX: Quick & Secure Steps
Let’s walk through the process of buying USDT, one of the most widely used stablecoins, using the OKX mobile app:
- Open the OKX app and go to the homepage.
- Tap 【Quick Buy】 (快捷买币).
- Enter either the amount you’d like to spend or the quantity of USDT you want to purchase.
- Select 【Buy USDT】, then tap 【Confirm】.
- Choose your preferred payment method (e.g., bank transfer, Alipay, WeChat Pay).
- Click 【Confirm Purchase】.
Once your order is placed:
- Tap 【Next】 and proceed to your chosen payment app (like mobile banking, Alipay, or WeChat).
- Transfer the exact amount to the seller’s provided account.
- After completing the transfer, return to OKX and click 【I’ve transferred, notify seller】.
The seller will verify your payment. Once confirmed, your USDT will be credited to your account instantly. You can view your balance under the 【Assets】 section.
Key Tips When Buying Crypto
To ensure a smooth and secure experience when buying digital assets on OKX:
- Provide bank statement screenshots if requested. Some sellers may ask for proof of bank activity to verify your account legitimacy. This helps prevent fraud and protects both parties.
- Use only a KYC-verified, real-name registered bank card for payments.
- The minimum and maximum limits for quick buy transactions are 10 CNY and 1,000,000 CNY per transaction.
- For transfers over 50,000 CNY outside business hours (after 5:00 PM to 8:00 AM on weekdays or holidays), consider splitting the payment to avoid delays due to interbank processing times.
- You can cancel an order before confirmation, but repeated cancellations or failed payments within the same day may affect your trading reputation, potentially blocking further trades temporarily.
Alternative Buying Options
Besides Quick Buy, you can also use:
- C2C Trading: Browse individual seller offers and choose one that matches your preferred price and payment method.
- Large-Amount Trading (≥100,000 CNY): Use the 【Advanced Filters】 > 【Bulk Trading】 option to find high-volume sellers with better rates and faster settlement.
How to Sell Crypto on OKX: Turn Digital Assets into Cash
Selling cryptocurrency reverses the buying process — you exchange your BTC, USDT, or other digital tokens for fiat money.
Here’s how to sell USDT on OKX:
- From the OKX app homepage, tap 【Quick Buy】.
- Switch to 【Sell Crypto】 (去卖币).
- Enter the amount of USDT you wish to sell or the target CNY amount.
- Tap 【Sell USDT】, then confirm the details.
- Select your preferred payout method (bank account, Alipay, etc.).
- Confirm the sale and enter your Google Authenticator code for added security.
After placing your order:
- Wait for the buyer to complete payment.
- Once the “Payment Received” indicator turns green, log in to your banking app to confirm the funds have arrived.
- Only after verifying the deposit should you click 【Confirm Receipt】 to release the USDT to the buyer.
Important Safety Reminders When Selling
- If no payment arrives within the expected timeframe, use the 【File Complaint】 feature. The system will freeze the transaction while OKX support investigates.
- Never release crypto before confirming that funds are in your account — even if the platform shows "paid." Scammers may fake payment proofs.
You can also explore alternative selling methods:
- Use C2C Sell Section: Manually select a trusted buyer from available listings.
- For large-volume sales (≥100,000 CNY), apply filters to access bulk trading options with institutional-grade liquidity.

Frequently Asked Questions (FAQs)
Q: Is it safe to buy crypto via OKX’s Quick Buy feature?
A: Yes. OKX uses advanced encryption, two-factor authentication (2FA), and escrow services during C2C trades to protect users. Always verify payment before releasing funds.
Q: Why do some sellers ask for bank statement screenshots?
A: This is part of anti-fraud verification. It ensures the bank account used for transactions belongs to a legitimate user and reduces risks of chargebacks or money laundering.
Q: Can I use someone else’s bank card to buy crypto?
A: No. All transactions must be conducted using a KYC-verified personal bank account matching your identity on file. Using third-party cards violates platform rules and may result in account suspension.
Q: What happens if I accidentally mark a payment as complete but haven’t sent money?
A: This can damage your credibility score. If detected, repeated misuse may lead to temporary restrictions on placing new orders.
Q: How long does it take for USDT to appear in my wallet after purchase?
A: Typically within minutes after the seller confirms receipt of payment. Delays may occur during peak times or if verification is needed.
Q: Are there fees for buying or selling on OKX?
A: While OKX doesn’t charge buyers directly in P2P trades, some sellers may include small premiums. Always review prices carefully before confirming.
