OKX beginners only need to complete registration, identity verification, link a payment method, purchase USDT, trade cryptocurrencies, and finally withdraw funds to finish the entire workflow.
Today we will introduce the world’s top‑three digital asset exchanges—OKX—and walk through the basic usage steps. This article covers registration, app installation, linking personal information, depositing, buying and selling tokens, and withdrawing, helping newcomers independently complete the full chain from USDT purchase to cash‑out.
First, prepare the following items:
- Mobile phone number or email address
- Government‑issued ID
- WeChat Pay, Alipay, or bank card
We have prepared a complete starter guide for beginners, covering everything from registration, identity verification, depositing, USDT purchase, token trading, to secure withdrawal. With illustrated screenshots, even users with zero experience can quickly become familiar with OKX operations and start their crypto trading journey with confidence.

iOS
iOS requires downloading the Binance app for identity verification (U.S. users should download Binance.US). It is recommended to purchase a Taiwan or South Korea Apple ID on Taobao (search for “台湾苹”), log in, and then download the regional OKX app. Whether you use a U.S., Taiwan, or Hong Kong Apple ID, the same app version will be installed.
Tip: The first time you open the app it may default to English or the wallet view; you will need to manually switch to Simplified Chinese and enter the exchange mode.
Set Language to Chinese
- Open the app and tap the dotted icon in the upper‑left corner to access your profile.
- Choose Preferences → Language, and switch the language to Simplified Chinese.
If the app opens to the wallet view by default, tap the Web3 button at the top‑center, then switch to Exchange.
3. Identity Verification
- Open OKX, tap Log In, and enter the account and password you registered.
- After logging in, tap Skip to reach the home page.
- On the home page you will see a “Complete Identity Verification” prompt; tap Go Verify → Verify Now.
Basic Verification (Level 1)
- Choose Identity Card as the document type, manually enter your full name and ID number, then submit.
- After approval, the system will prompt you to perform Level 2 verification. It is recommended to continue to Level 2 or even Level 3 to unlock higher deposit and withdrawal limits.
4. Link a Payment Method
- From the home page, tap the nine‑dot grid in the upper‑left corner, select C2C Trading, then tap My in the lower‑right corner.
- Tap Payment Account Management → Add Now → choose Payment Method.
Add a Bank Card
- Enter the card number and issuing bank, obtain the verification code, and tap Save.
Add Alipay or WeChat Pay
- Choose the appropriate channel, enter the account, upload the QR code, receive the verification code, and save.
5. Deposit USDT
- Tap Buy Crypto on the home page → C2C Buy.
- In the upper‑right Filter menu, select the payment method you linked earlier (e.g., Alipay), and confirm.
- Enter the purchase amount (example $15). The system will automatically match merchants with large transaction volumes and high success rates.
- After selecting a merchant, tap Buy → 0 Fee USDT Purchase.
- In the chat window, tap Proceed to Pay → View QR Code, and complete the payment using Alipay.
- Once payment is done, tap I Have Paid, and wait for the seller to release the USDT.
When the deposit succeeds, you will see the received USDT (e.g., 13.47 USDT) on the assets page.
Note: For fiat deposits you may also use SEPA or SWIFT transfers where available, depending on your region and the payment methods supported by OKX.
6. Trade Cryptocurrencies
Transfer Funds
- Navigate to Assets → Funding Account → Transfer, and move USDT from the funding account to the trading account.
Trading Steps
- Tap the Trade tab at the bottom, then select a trading pair in the upper‑left corner (e.g., BTC/USDT).
- In the search box type the token name (e.g., “BTC”) and tap the corresponding pair.
- Choose the red Ask price on the right, enter the amount of USDT you wish to spend (e.g., 10 USDT), and tap Buy BTC to complete the purchase.
To view your position:
- Go to Assets → Trading Account, where you will see the BTC you have purchased.
The sell process mirrors the buy flow: select Sell, input the quantity, confirm, and the BTC will be converted back to USDT.
