Step 1: Download the OKX App and Register
Before buying any cryptocurrency, you’ll need to create an account on OKX.
- For Android users: Visit the official OKX website and scan the QR code to download the app directly.
- For iOS users: You’ll need an Apple ID registered outside of mainland China (such as a Taiwan or U.S. account) to access the App Store version of OKX. After scanning the QR code on the OKX site, follow the prompts to install the app.
Once downloaded:
- Open the app and register using your Chinese mobile number.
- Set a strong password to protect your account.
Registration is quick and straightforward—no lengthy forms or unnecessary steps.
Step 2: Complete Identity Verification
To unlock full trading capabilities and increase withdrawal limits, you must complete identity verification (KYC).
Here’s how:
- Tap the profile icon in the top-left corner.
- Go to Identity Verification.
- Select Basic & Advanced Verification.
- Enter your full name and ID number.
- Upload clear photos of both sides of your government-issued ID (e.g., Chinese ID card).
- Complete facial recognition as prompted.
Verification usually takes just a few minutes. Once approved, you’ll see a “Verified” status—this means you’re ready to trade.
Additionally, head to Security Settings to enhance account protection:
- Link your email address
- Set up Google Authenticator for two-factor authentication (2FA)
These steps significantly reduce the risk of unauthorized access.
Step 3: Buy USDT Using Fiat Currency
The most efficient way to start trading on OKX is by purchasing USDT (Tether)—a stablecoin pegged 1:1 to the U.S. dollar. USDT acts as a bridge currency, allowing you to trade for other cryptocurrencies at competitive rates.
How to Buy USDT:
- From the homepage, tap Quick Buy.
- Choose USDT as the cryptocurrency.
- Enter the amount in CNY (Chinese Yuan) you’d like to purchase.
- Select your preferred payment method (e.g., bank transfer, Alipay, WeChat Pay).
- Confirm the order.
OKX will automatically match you with a seller. You can communicate with them directly via the in-app chat to confirm details.
After confirming the transaction:
- Leave the app and send the payment to the seller using your chosen method.
- Return to OKX and click I’ve Transferred to notify the seller.
- Once confirmed, the USDT will be credited to your Funding Account within minutes.
Step 4: Transfer Funds to Your Trading Account
By default, purchased USDT lands in your Funding Account, which is used for deposits and withdrawals. To trade, you need to move it to your Trading Account.
How to Transfer:
- Tap Assets > Fund Transfer.
- Select USDT as the coin.
- Choose transfer direction: From Funding Account to Trading Account.
- Click All to transfer the full balance.
- Confirm with your password or 2FA.
This process is instant and free of charge.
Now that your USDT is in the trading account, you're ready to buy TRX, BTC, ETH, or any other supported cryptocurrency.
Step 5: Trade USDT for TRX or Other Cryptos
Let’s say you want to buy TRX (Tron) using your USDT.
Using Limit Order (Recommended for Price Control):
- Tap Trade at the bottom menu.
- Search for TRX/USDT trading pair.
- Under Order Type, select Limit.
- Enter your desired price (e.g., slightly below current market rate).
- Input the quantity of TRX you wish to buy.
- Tap Buy TRX > Confirm.
Your order will be placed on the order book and executed only when the market reaches your specified price.
Using Market Order (Instant Execution):
If you want immediate results:
- Switch to Market Order mode.
- Enter the amount of TRX or equivalent USDT value.
- Tap Buy TRX.
The system executes your order instantly at the best available price.
💡 Pro Tip: Use limit orders during volatile markets to avoid slippage and ensure better pricing.
