The single most important rule in crypto is verifying the authenticity of every link you click. Phishing sites are rampant.

1. Official Website: Manually type https://www.okx.com into your browser’s address bar. Do not click links from emails, social media DMs, or search engine ads unless you are 100% certain of their legitimacy.
2. Desktop vs. Mobile:
   • Desktop (Web): Ideal for detailed chart analysis, using advanced trading tools, and managing a large portfolio. Bookmark the official site once verified.
   • Mobile App: Essential for on-the-go monitoring and trading. Only download from official sources:
     • iOS: Search for “OKX” directly in the Apple App Store. The developer should be “OKX Technology Company Limited.”
     • Android: Download the APK directly from the official OKX website (okx.com/download). Do not download crypto exchange apps from third-party Android stores.
3. Immediate Action: Once on the official site or app, locate the “Sign Up” button. You are now ready for the next critical step.

⚠️ Risk Warning: Downloading apps from unofficial sources is the #1 cause of account theft. Fake apps can steal your login credentials and seed phrases the moment you enter them.

This step secures your account and unlocks lifelong financial benefits. Pay close attention to the referral code field.

1. Choose Registration Method: You can typically register using your mobile phone number or email address. Using an email you control and secure with 2FA is often recommended for easier recovery.
2. The Critical Referral Field: During sign-up, you will be prompted for a “Referral Code” or “Invitation Code.” This is non-negotiable for maximizing value. Enter the following code exactly: 34978585
   • Why This Matters: This code activates a 20% discount on your trading fees for the lifetime of your account. On a $10,000 trade, this can save you $2-$10 per transaction, compounding into thousands saved annually for active traders.
3. Complete Basic Info: Follow the prompts to set a strong, unique password (use a password manager) and agree to the terms. Verify your email/phone with the code sent to you.

Know Your Customer (KYC) is not a hurdle; it’s a security feature that protects you and unlocks full platform functionality.

1. Navigate to Verification: In your account dashboard, find “Verification” or “Identity Verification.”
2. Tiered Levels: OKX usually has levels (e.g., Basic, Intermediate, Advanced). Start with the basic level, which typically requires:
   • Government-Issued ID: A passport, driver’s license, or national ID card.
   • Selfie/Liveness Check: You will be asked to take a real-time photo or short video of yourself. Ensure good lighting and follow the on-screen prompts carefully.
3. Submission & Wait: Submit the documents. Verification can take from a few minutes to several hours. Do not attempt to submit fake or edited documents—this will result in a permanent ban.
4. Post-Verification Benefits: Once verified, your daily withdrawal limits increase dramatically, you gain access to fiat deposit/withdrawal channels (bank transfer, card), and you can participate in token sales and earn products.

⚠️ Risk Warning: Never share your KYC documents or selfie videos with anyone claiming to be “support” via Telegram or WhatsApp. Official support will never ask for this outside the secured platform interface.

Before you deposit a single dollar, you must fortify your account. This is more important than any trading strategy.

1. Enable Two-Factor Authentication (2FA): Go to Security Settings. Enable Google Authenticator (TOTP) or a similar app-based 2FA. SMS-based 2FA is vulnerable to SIM-swap attacks and is not sufficient.
2. Anti-Phishing Code: Set a unique anti-phishing code. This will be included in all genuine OKX emails, allowing you to instantly spot phishing attempts.
3. Withdrawal Address Whitelisting: This feature locks cryptocurrency withdrawals to only pre-approved wallet addresses you set. Even if a hacker accesses your account, they cannot send funds to their own wallet.
4. Device & Session Management: Regularly review active login sessions and devices. Log out of unused sessions and remove unrecognized devices.

Now you’re ready to fund your account. Understand the difference between exchange wallets and self-custody.

1. Fiat Deposit (Recommended for Beginners):
   • Link your verified bank account or card within the “Buy Crypto” or “Deposit” section.
   • You can directly purchase major cryptocurrencies like BTC, ETH, or USDT with your local currency.
2. Crypto Deposit:
   • Navigate to “Deposit” -> “Crypto.”
   • CRITICAL: Select the correct network/chain (e.g., for USDT, you might choose between ERC-20, TRC-20, OKTC). Sending funds on the wrong network will result in permanent loss.
   • Copy the deposit address provided by OKX or scan the QR code. Send a small test transaction first.
3. The Golden Rule of Custody: Not your keys, not your coins. Funds on an exchange are under its custody. For long-term storage of significant amounts, use a personal hardware wallet (e.g., Ledger, Trezor). Use exchanges for trading and active investing, not as a bank vault.

[!CAUTION] Final and Critical Risk Summary:

1. Market Risk: Cryptocurrency prices are extremely volatile. Never invest more than you can afford to lose.
2. Counterparty Risk: Exchanges can face operational issues, hacks, or regulatory actions. Diversify across platforms and use self-custody for savings.
3. User Error Risk: Wrong addresses, wrong networks, and phishing are the leading causes of asset loss. Double-check every transaction detail. Security is your permanent responsibility.
