Newcomer Guide: 2026 OKX App Official Website Registration Full Tutorial – Use Referral Code〖BTC45〗to Enjoy 20% Trading Fee Discount

For Android users in most regions:

• Visit the official OKX website at okx.com/join/BTC45 directly from your phone browser.
• Click the “Download” button. The site automatically detects your system and offers the latest Android APK. The download link on the official site is the ONLY safe channel; never install APKs from third-party websites.
• If Google Play is available in your region, search for “OKX” and verify the developer name is “OKX”. If you see it, download from the store directly.

For iOS users:

• Open the App Store and search for “OKX”. Confirm the developer is “OKX TECHNOLOGY LIMITED” or the official regional name. Download at your own discretion if the app is available in your store.
• If OKX has been removed from your local App Store due to regional restrictions, you need to use the official installation profile via Safari—this is known as a "enterprise signature" or "TestFlight" method. But again, be extremely cautious: the only authoritative source is the official OKX website.

⚠️ Risk Tip #1: Fake OKX apps exist in some unofficial app stores and can steal your private keys. Always cross-check the download source: the official site domain is exactly okx.com. Bookmark it now.

Once the app is installed and opened, tap “Sign Up” on the home screen. You have two options: email or mobile number. For 2026, I strongly recommend using email—especially a secure, private email address dedicated only to exchange accounts.

• Email/Phone: Enter your address/number, create a strong password (at least 12 characters, upper/lowercase, numbers, symbols).
• Referral Code: Look for a field labeled “Referral Code” (sometimes hidden under “Invitation Code”). Enter Enter Referral Code：Referral Code to permanently activate the 20% fee discount. You can also enter it later under “Rewards Hub”, but it’s best to do it at sign-up.
• Read the user agreement and check the box, then click “Create Account”.

🔐 Security note: Use a brand-new password. Never reuse the password from your email or other sites. This account holds real money.

Immediately after signing up, OKX sends a 6-digit verification code to your email or phone. Enter this code to prove you are the owner.

• Check your spam folder if you don’t see the email within 2 minutes.
• If using SMS and the code doesn’t arrive, wait 60 seconds and resend. Do not tap resend multiple times in a row, as the previous code becomes invalid.
• For beginners: this step is where many get stuck. If the email link appears to be broken, copy the entire link into your browser manually, and ensure it goes to okx.com.

Security is non-negotiable in crypto. OKX will push you to enable 2FA. I urge you to do it NOW, not later.

• Go to Profile → Security Settings → Two-Factor Authentication (2FA).
• Choose Google Authenticator or Microsoft Authenticator (hardware keys like YubiKey are even better).
• Scan the QR code with your authenticator app and enter the 6-digit code to confirm.
• Write down the 16-character recovery keys on paper and store them in a safe place—not in your phone notes, not in cloud storage.

⚠️ Risk Tip #2: If you lose your phone and don’t have backup keys, you risk losing access to your account forever. The support process to recover an account without 2FA can take weeks.

To comply with global regulations, OKX requires identity verification (KYC) before you can deposit, trade, or withdraw. There are three verification tiers:

• Level 1 (Basic): Provide your full name, date of birth, and country of residence. This tier only allows some crypto deposits and limited withdrawal.
• Level 2 (Advanced): Upload a photo of your government-issued ID (passport or national ID) and complete a liveness selfie. This unlocks unlimited spot/futures trading and full withdrawals. For long-term use, complete Level 2.
• Level 3 (Institutional): For high-net-worth individuals and funds. Usually requires additional proof of address and source of funds.
• In the OKX app: Profile → Identity Verification → choose your region → follow the prompts. The liveness check takes about 30 seconds. Ensure good lighting and no sunglasses.

💰 Investment logic: KYC might feel invasive to privacy purists, but regulated exchanges like OKX are required to conduct it. Accounts with full KYC have higher withdrawal limits, lower compliance flags, and faster support resolution.

Now that your account is verified, it’s time to fund it. For absolute beginners, the easiest methods are:

• Option A (Crypto transfer): Buy USDT on another exchange or wallet, then on OKX go to “Assets → Deposit → USDT → select network (TRC-20 or ERC-20) → copy the address”. Send a small test deposit first, then the rest.
• Option B (P2P trading): Go to “Trade → P2P Trading” in 2026. This is integrated into OKX: you buy USDT directly from a local merchant using bank transfer, and the USDT lands directly in your OKX account. Simpler for those without existing crypto.
• After depositing, check your fee discount: go to “Rewards Hub” or “Fee Rate”. If you see “VIP level 0, 20% discount confirmed”, your Enter Referral Code：Referral Code is active. If not, immediately contact OKX support to apply it before making any trades.

📈 Case study: Trader "Ms. Zhu" from Singapore deposited USDT, copied the OKX referral code from a tutorial like this one, and never paid the standard fee again. By her third month of active trading, her accumulated fee savings equaled 34% of her net profit. That’s real freemium value.

In the app, tap “Trade” on the bottom navigation bar, then select “Spot”. The trading pair list appears. Search for “BTC/USDT” if you want to buy Bitcoin, or “ETH/USDT” for Ethereum. For absolute beginners, don’t touch leverage or derivatives until you have at least 20 hours of practice.

• Use Limit Order: set the highest price you are willing to pay. This gives you a maker fee discount.
• Use Market Order: buy immediately at current market price. As the buyer, you pay the taker fee—still totally fine thanks to the 20% discount.
• Start with a small allocation: 10% of your total crypto budget.

Before you press Buy, set your exit plan. Use the exchange’s built-in “Trigger Order” function: choose “Stop-Loss” at -7% from entry price and “Take-Profit” at +15% initially. This habit prevents catastrophic losses and locks in profits automatically.

Does the 20% discount help here? Absolutely—when you close the position, the lower fee preserves more of your realized profit.

After your first trade, go to “Order History” and tap “Fee Detail”. Compare the fee with OKX’s standard rate; notice it is 20% lower. Log your execution fee in a personal spreadsheet every week. In 2026, fee tracking is a core practice of professional traders. If you see the standard fee being charged despite the referral code, open a support ticket immediately and attach your referral code registration proof.
