Step 2: Complete Identity Verification (KYC)
To unlock full trading capabilities — including higher withdrawal limits and access to regulated services — you must complete Know Your Customer (KYC) verification.
Here’s how:
- Go to "Profile" > "Identity Verification"
- Select your country/region

Verification typically takes just a few minutes, though processing times may vary depending on volume.
✅ Once verified, you’ll gain access to enhanced features like P2P trading, credit/debit card purchases, and futures markets.
Step 3: Deposit Funds into Your OKX Account
With your identity confirmed, it’s time to fund your account. OKX supports various deposit methods:

To deposit:

Step 4: Buy Bitcoin (BTC) or USDT Using Trading Pairs
Now that your account is funded, you can purchase Bitcoin or USDT directly through the trading interface.
Navigate to the Market Section
- Tap "Markets" or "Trade" in the app
- Search for the BTC/USDT trading pair
- You’ll see real-time price data, order book depth, and recent trades
Choose Your Order Type
OKX offers two primary ways to buy:
✅ Market Order (Instant Purchase)
- Buys BTC or USDT at the best available current price
- Execution is immediate
- Ideal if you want to enter the market quickly
Example: If BTC is trading at $63,500, placing a $635 market order will get you approximately 0.01 BTC (minus small fees).
✅ Limit Order (Price-Controlled Purchase)
- Set your desired buy price
- The trade executes only when the market reaches that price
- Useful for dollar-cost averaging or waiting for dips
Example: Set a limit order at $62,000 for BTC. When the price drops to that level, your order fills automatically.
Enter the amount you wish to buy, review fees (typically under 0.1%), and confirm the transaction.
Step 5: Confirm and Complete the Transaction
Before finalizing:
- Double-check the amount and price
- Review network fees (for withdrawals later)
- Ensure two-factor authentication (2FA) is enabled
Tap "Buy BTC" or "Buy USDT", then confirm with your password or biometric authentication.
Once complete, your purchased assets will appear in your Wallet under “Spot Assets.”
Step 6: Manage and Withdraw Your Crypto
After buying BTC or USDT, you have several options:
- Hold in your OKX wallet
- Trade for other cryptocurrencies
- Transfer to an external wallet for long-term storage
How to Withdraw Crypto
- Go to "Assets" > "Withdraw"
- Select Bitcoin or USDT
- Enter your external wallet address
- Choose the correct network (e.g., TRC20 for USDT, Bitcoin network for BTC)
- Enter amount and confirm with 2FA
⚠️ Warning: Always test with a small amount first. Sending funds to the wrong network may result in permanent loss.
