🔐 Security Tip: Always enable Two-Factor Authentication (2FA) during setup. Use Google Authenticator instead of SMS for stronger protection against phishing and SIM-swapping attacks.
Once registered, log in and proceed to identity verification—a crucial step for unlocking full platform features.
Step 2: Complete Identity Verification (KYC)
To comply with global anti-money laundering (AML) regulations, OKX requires users to complete Know Your Customer (KYC) verification.
Verification Steps:
- Navigate to your Account Settings or Profile Center.
- Select “Identity Verification.”
- Upload a clear photo of your government-issued ID (passport, driver’s license, or national ID).
- In some cases, submit a selfie holding your ID.
- Wait for approval—usually within minutes to 24 hours.
✅ Upon completion, you’ll gain access to higher withdrawal limits, fiat deposits, and advanced trading tools.
Step 3: Deposit Funds into Your OKX Account
You can fund your account in two main ways: fiat currency or existing cryptocurrencies.
Option A: Fiat Deposit (Beginner-Friendly)
- Click on Assets > Deposit.
- Choose your local currency (e.g., USD, EUR, GBP).
- Select a payment method: bank transfer, credit/debit card, or supported e-wallets.
- Enter the deposit amount and follow the prompts to complete payment.
- Funds typically arrive instantly or within a few minutes.
Option B: Crypto Deposit
If you already own stablecoins like USDT or ETH:
- Select Crypto Deposit under the Assets section.
- Choose the cryptocurrency you want to transfer (e.g., USDT on TRON or Ethereum network).
- Copy the unique deposit address provided by OKX.
- Send funds from your external wallet or another exchange.
⚠️ Always double-check network compatibility (e.g., TRC20 vs ERC20) to avoid fund loss.

OKX offers multiple ways to buy Bitcoin. Here are the three most common methods:
A. Instant Buy with Fiat (Fastest for Beginners)
- Go to the Buy Crypto page.
- Select Bitcoin (BTC) as the cryptocurrency.

B. Spot Trading (More Control Over Price)

Choose between:

- Enter quantity or total value, then click “Buy BTC.”
📊 This method suits users who want flexibility and real-time market engagement.
C. OTC Trading (Best for Large Amounts)
For high-volume purchases with fixed pricing:

- Select a reputable seller with high completion rates.
- Initiate a trade, send payment via bank transfer or other agreed method.
- Once the seller confirms receipt, BTC is released to your account.
🛡️ OTC minimizes slippage and avoids market impact during large buys.
