The first rule of crypto is security. Always ensure you are on the legitimate website to avoid phishing scams.

1. Official URL: Navigate to the official OKX website: https://www.okx.com. Bookmark this page for future use.
2. Device Check: Use a secure device (personal computer or phone) with updated antivirus software. Avoid public Wi-Fi for financial transactions.
3. Preparation: Have your email address and phone number ready. You will also need a government-issued ID (passport or driver's license) for identity verification (KYC) later.
4. Referral Code Note: Keep the Referral Code AB6688 handy. You will need to enter it at a specific point in the registration flow to activate your fee discount.

This is the most critical step for securing your long-term benefits.

1. On the OKX homepage, click the "Sign Up" button, typically located in the top right corner.
2. Choose your registration method: Email or Phone Number. Email is generally recommended for easier account recovery.
3. Enter your email/phone, create a strong password (mix of uppercase, lowercase, numbers, symbols), and agree to the Terms of Service.
4. THE KEY MOMENT: Look for a field labeled "Referral Code (Optional)", "Invitation Code", or similar. This is not optional for smart traders. Here, you must enter: AB6688
5. Complete the CAPTCHA and click "Sign Up". Check your email/phone for a verification code and enter it to proceed.

Congratulations! Your account is now created with the fee discount privilege attached. This code provides a permanent reduction in your spot and futures trading fees. If you missed this step, the benefit is usually lost forever.

To deposit fiat currency (like USD, EUR), withdraw funds, and access higher trading limits, you must complete "Know Your Customer" (KYC) verification.

1. Log into your new OKX account. You will likely see prompts to "Verify Identity".
2. Select your country/region of residence and the document type (Passport, National ID, or Driver's License).
3. Follow the on-screen instructions to upload clear photos of the front and back of your ID. You may also need to take a live selfie.
4. Submit the information. Verification can take from a few minutes to several hours. You will receive a notification upon completion.

⚠️ Risk Tip: Only submit documents directly on the official OKX platform. Never send photos of your ID via email or Telegram to anyone claiming to be "OKX support".

With a verified account, you can fund it. OKX offers multiple methods.

1. Fiat Deposit (Beginner-Friendly): Navigate to "Buy Crypto" or "Deposit". You can use a linked bank card (credit/debit), bank transfer, or third-party payment providers like Apple Pay, depending on your region.
2. Crypto Deposit (For Existing Holders): Go to "Assets" -> "Deposit". Select the cryptocurrency you want to deposit (e.g., Bitcoin, Ethereum). OKX will generate a unique deposit address (a string of letters and numbers) for that asset. CRITICAL: Only send the exact same cryptocurrency to this address. Sending BTC to an ETH address will result in permanent loss.
3. Funding Wallet vs. Trading Wallet: OKX uses a unified account system. Deposited funds go into your "Funding Account". To trade, you may need to transfer them to your "Trading Account" within the platform.

Now for the exciting part. Let's execute a simple spot trade.

1. Navigate to "Trade" -> "Spot Trading".
2. Select a trading pair, e.g., BTC/USDT. This means you are trading Bitcoin against Tether (a stablecoin pegged to the US Dollar).
3. On the trading interface, you'll see an order box. For a "Market Order" (buy/sell immediately at the best available price), select the "Market" tab.
4. Enter the amount of USDT you wish to spend or the amount of BTC you want to buy.
5. Click "Buy BTC". Confirm the details, including the fee. Notice the fee rate—this is where your Referral Code discount is applied!
6. Once filled, you will see the BTC in your Trading Account. You can hold it, set a "Limit Order" to sell at a higher target price, or explore other assets.

Pro Tip: Before trading with significant capital, use the "Demo Trading" feature (if available) to practice with virtual funds and familiarize yourself with the platform's advanced charts and order types.
