Core Keywords:

Step 1: Download and Install the OKX App

Accessing OKX from mainland China may require alternative app installation methods since it's not available on domestic Android stores or the mainland Apple App Store.

For iOS users:
You can download the official OKX app via an overseas Apple ID—such as one registered in Taiwan. These accounts are widely available through third-party services. Once logged into a non-mainland Apple ID, search for "OKX" in the App Store to install the verified application.

For Android users:
If your device blocks direct downloads from unknown sources, simply enable “Install Unknown Apps” in settings and download the APK from the official OKX website. While some phones may flag the file as risky, this is standard behavior for apps not hosted on Google Play.

Rest assured, OKX is a regulated and globally recognized exchange with strong compliance standards—its presence on international financial app charts confirms its legitimacy.

Step 2: Register Your Account

Begin by creating your OKX account:

  1. Open the app and tap Sign Up.
  2. Select your country or region—choose China as your residence.
  3. Use a reliable email provider like Gmail or Outlook for registration.
  4. Agree to terms and proceed.

💡 Pro Tip: To permanently reduce trading fees by 20%, use a referral link during sign-up. This bonus applies to all future transactions without affecting your account privileges.

Step 3: Complete Identity Verification (KYC)

To unlock full trading capabilities—including deposits, withdrawals, and higher limits—you must complete Know Your Customer (KYC) verification.

Here’s how:

  1. Navigate to Profile > Verification.
  2. Choose ID Card or Passport as your document type.
  3. Upload clear photos of both front and back sides of your ID.
  4. Perform facial recognition to confirm identity.

Approval typically takes just minutes. Once verified, you can access all features, including C2C trading, spot markets, and derivatives.

Step 4: Deposit Funds Using C2C Trading

The most effective way to fund your OKX account with RMB is through C2C (peer-to-peer) trading. This method connects buyers and sellers directly, allowing you to pay via Alipay, WeChat Pay, or bank transfer.

How to Buy USDT with RMB:

  1. Go to Buy Crypto > C2C.
  2. Select Buy USDT.
  3. Enter the amount in CNY (e.g., ¥1,000).
  4. Choose a payment method: Alipay is often fastest.
  5. Review seller details: prioritize high completion rate (>99%) and large trade volume.
  6. Click Buy USDT, then Preview Order.
  7. Confirm payment after checking seller instructions (e.g., no备注).
  8. Pay outside the app via your chosen method.
  9. Mark as paid in-app; once confirmed, USDT will be released to your wallet.

USDT (Tether) is a stablecoin pegged 1:1 to the US dollar, making it ideal for entering crypto markets without volatility risk during onboarding.

Step 5: Transfer Funds to Trading Account

After purchasing USDT, it lands in your Funding Account by default. To trade, transfer it to your Trading Account:

  1. Tap Assets > Transfer.
  2. Select From: Funding Account, To: Trading Account.
  3. Choose USDT and enter amount (or max).
  4. Confirm transfer—usually completed instantly.

Step 6: Start Spot Trading

Now that your funds are ready, begin trading major cryptocurrencies:

  1. Tap Trade > Spot.

  2. Search for a trading pair:

    • For Bitcoin: BTC/USDT
    • For Ethereum: ETH/USDT
    • For Dogecoin: DOGE/USDT

  3. On the buy screen, choose between:

    • Limit Order: Set your desired price (e.g., buy DOGE at $0.30).
    • Market Order: Instant execution at current price.

For quick entry, use market orders. Slide to select quantity (e.g., max), then tap Buy DOGE.

Your purchased coins will appear under Assets > Spot Account.

Step 7: Sell Crypto and Withdraw RMB

When it’s time to cash out:

  1. Go to Trade > Spot, select the asset (e.g., DOGE).
  2. Tap Sell, choose Market Order, set amount, and confirm.
  3. Your proceeds will be in USDT in the trading account.

Then:

  1. Transfer USDT back to Funding Account.
  2. Return to Buy Crypto > C2C > Sell USDT.
  3. Filter sellers by high reputation and preferred payout method (e.g., Alipay).
  4. Initiate sale and wait for buyer’s payment.
  5. Confirm receipt of funds before releasing USDT.

⚠️ Always verify actual bank/Alipay credit before releasing crypto—this prevents fraud.

Frequently Asked Questions (FAQ)

While mainland financial institutions are prohibited from handling cryptocurrency transactions, personal ownership and offshore trading are not explicitly illegal. Millions of Chinese users trade via international platforms like OKX using P2P methods.

Yes—through OKX’s C2C marketplace, you can link Alipay or WeChat Pay to buy USDT directly from verified sellers using RMB.
