Complete Identity Verification (KYC) Before Trading
Before you can buy cryptocurrency using fiat money (like CNY), you must complete Know Your Customer (KYC) verification. This is a standard requirement across regulated exchanges to prevent fraud and comply with anti-money laundering (AML) policies.
Steps to complete KYC on OKX:
- Log in to your account and go to the "Verification" section.
- Choose your country/region and select the ID type (e.g., passport, national ID).
- Upload clear photos of your document and take a live selfie for facial recognition.
- Wait for approval — usually processed within minutes to 24 hours.
Completing KYC unlocks higher withdrawal limits, enables fiat deposits, and allows participation in advanced trading features.
How to Buy Crypto via C2C Trading Without Freezing Your Bank Card
One of the biggest concerns for users in mainland China is the risk of bank card freezing during peer-to-peer (P2P) or over-the-counter (OTC) transactions. While direct banking links aren't supported due to regulatory restrictions, C2C trading remains a viable option through third-party payment methods.
Best Practices to Avoid Card Freezes:
- Use dedicated bank cards: Never use your primary salary or savings card. Open a separate account exclusively for crypto transactions.
- Avoid large single transfers: Split large purchases into smaller amounts over time to reduce red flags.
- Communicate only within the OKX chat system: Do not share personal contact info or conduct trades outside the platform.
- Choose high-reputation merchants: Look for sellers with high completion rates (>95%), many completed orders, and positive feedback.
- Stick to Alipay or WeChat Pay cautiously: These are commonly accepted but may trigger scrutiny if used frequently.
By following these precautions, you significantly lower the chance of triggering bank alerts or account restrictions.

Finding Reliable OTC Sellers on OKX
The OKX C2C marketplace connects buyers and sellers directly. To find trustworthy traders:
- Navigate to the “Trade” section and select “C2C Buy.”
- Choose USDT as the cryptocurrency and your local currency (e.g., CNY).
- Filter results by payment method (Alipay, WeChat, bank transfer).
- Sort by seller rating, transaction volume, and response time.
- Read recent user reviews before initiating a trade.
Always initiate payment only after the seller has locked the cryptocurrency in escrow. OKX holds the digital assets until you confirm receipt of funds, ensuring both parties are protected.
Step-by-Step Fiat Deposit Process on OKX
Here’s how to deposit fiat and acquire crypto:
- Go to “Funding” > “Deposit” > “Fiat via C2C.”
- Select your preferred currency and payment method.
- Browse available offers and choose one with favorable rates.
- Enter the amount you wish to buy and click “Buy USDT.”
- Confirm the order and make payment through your selected method.
- Once confirmed by the seller, your USDT will be credited instantly.
This entire process is secure, transparent, and fully integrated within the OKX ecosystem.
Transferring Funds Between OKX Accounts
OKX offers different account types — funding account, trading account, and earn account — allowing users to manage their assets efficiently.
To transfer funds:
- Go to “Assets” > “Transfer.”
- Select source and destination accounts.
- Enter the amount and confirm with two-factor authentication (2FA).
This feature helps organize capital for spot trading, futures, staking, or saving without leaving the platform.
Trading Stablecoins for Bitcoin or Other Cryptos
After acquiring USDT or another stablecoin via C2C, you can easily trade it for Bitcoin (BTC), Ethereum (ETH), or other altcoins:
- Go to the “Spot Trading” page.
- Search for the BTC/USDT trading pair.
- Place a market or limit order based on your strategy.
- Confirm the transaction — your Bitcoin will appear in your wallet immediately.
Stablecoins act as a bridge between fiat and volatile cryptocurrencies, offering price stability during entry and exit points.
Reduce Trading Fees with Exclusive Discounts
All OKX users benefit from competitive fee structures, but you can further reduce costs:
- Complete KYC to unlock lower fee tiers.
- Hold OKB (OKX’s native token) to receive additional discounts.
- Use referral programs — though specific codes are removed per guidelines — ongoing promotions often provide up to 20% off trading fees.
Lower fees mean higher net returns, especially for active traders.

Withdrawing Funds Safely: Preventing Account Issues
When selling crypto and withdrawing fiat:
- Use the same payment method for withdrawals as used in deposits when possible.
- Keep transaction histories and chat logs as proof of legitimate trades.
- Avoid rapid movement of large sums; stagger withdrawals over days.
- Enable 2FA and withdrawal address whitelisting for added security.
These habits protect against both technical issues and potential regulatory scrutiny.
