Let’s talk numbers. In 2026, the average crypto trader on a major exchange pays over $1,200 annually in trading fees alone. That’s not an investment; it’s a silent tax on your portfolio’s growth. Now, imagine instantly slashing that figure by 20% from your very first trade, forever. This isn’t a hypothetical perk—it’s the immediate, tangible benefit of using the correct referral code when you sign up. The key to unlocking this is simple: Enter Referral Code: USDT45. For mainland Chinese users navigating a complex regulatory landscape, securing this discount isn’t just about saving money; it’s a foundational step in building a more efficient and resilient investment strategy from day one.

Step 1: Preparation and Risk Awareness #

Before clicking any link, understanding the environment is crucial. Mainland users operate within a specific regulatory framework that prohibits direct fiat-to-crypto transactions on offshore exchanges. Your journey begins with knowledge and the right tools.

💡 Tip: A stable internet connection and a valid international phone number or email for verification are non-negotiable. Consider using a reputable VPN service to ensure consistent access, though this carries its own operational risks.

⚠️ Risk Warning: Trading cryptocurrencies is highly volatile and speculative. You could lose your entire investment. This guide is for informational purposes only and does not constitute financial advice. Always Do Your Own Research (DYOR).

Step 2: Account Registration Process #

Navigate to the official Binance registration page. You will be prompted to enter your email address or phone number and create a strong password.

This is the most critical moment. During registration, you must enter the referral code in the designated field to activate the 20% fee discount. If you miss this step, the discount is permanently forfeited for that account.

💡 Tip: Double-check the code entry. A single typo means you’ll miss out on the lifetime benefit. The correct code is USDT45.

Step 3: Identity Verification (KYC) #

After registering, you must complete Know Your Customer (KYC) verification. This involves submitting photos of a government-issued ID (like a passport) and sometimes a facial recognition scan. This process is mandatory for raising withdrawal limits and accessing full platform features.

⚠️ Risk Warning: Only submit documents on the official Binance website or app. Beware of phishing sites mimicking Binance to steal your login credentials and identity documents. Always verify the URL.

💡 Tip: Ensure your documents are clear, all four corners are visible, and the information matches your registration details exactly. Processing can take from a few minutes to several days.

Step 4: Funding Your Account (No Direct CNY Deposit) #

Since direct CNY deposits are not supported for mainland users, you need to acquire crypto elsewhere first. Common methods include:

1. Peer-to-Peer (P2P) Trading: Use Binance’s own P2P platform to buy USDT from other users using Alipay or WeChat Pay. Scrutinize seller ratings and trade history.
2. Transfer from Another Wallet: If you already hold crypto (e.g., USDT, BTC) in another private wallet (like MetaMask or Trust Wallet), you can withdraw it to your new Binance deposit address.

⚠️ Risk Warning: When using P2P, never release funds before the crypto appears in your Binance funding account. Follow the platform’s escrow instructions precisely. Be wary of requests to trade off-platform.

Step 5: Making Your First Trade and the “Retroactive Filling” Myth #

Once your account is funded, you can start trading. Your 20% fee discount, activated by the USDT45 code, will apply automatically.

Important Clarification: The concept of “retroactive filling” of a referral code after registration is largely a myth for personal fee discounts. The referral benefit is typically tied to the initial registration event. If you missed it, you generally cannot add it later to your existing account. The only surefire way is to ensure correct entry at sign-up.

💡 Tip: To verify your discount is active, check your fee rate in the trading interface. It should reflect the discounted tier.

Step 6: Ongoing Security and Risk Management #

Your responsibility begins after registration. Enable Two-Factor Authentication (2FA) using an app like Google Authenticator. Never share your 2FA codes, seed phrases, or passwords. Be skeptical of “too-good-to-be-true” investment schemes promoted on social media.

💡 Tip: Regularly review your account’s security settings and connected devices. Use whitelisting for withdrawal addresses to prevent unauthorized transfers.

⚠️ Risk Warning: The crypto space is a target for sophisticated hackers and scammers. Your security is ultimately your responsibility. The exchange is not a bank; assets may not be insured in the same way.

Investment Logic and a Case Study #

The 20% fee discount is a powerful tool for compounding returns, especially for active traders. Consider a trader who executes $50,000 in monthly volume. At a standard 0.1% maker fee, that’s $50 in fees per month, or $600 annually. With the 20% discount, they save $120 yearly. Over 5 years, that’s $600 saved—money that can be reinvested.

Case Study: User “A” registered in 2023 without a referral code. User “B” registered simultaneously using code USDT45. Both traded identically. By 2026, User B had saved over $350 in fees, which they allocated to a promising altcoin that later doubled. User A’s identical trades netted less overall profit due to the cumulative fee drag. The lesson: Optimize your entry point. The discount creates a permanent efficiency advantage.

Conclusion: Building on a Smart Foundation #

Registering for Binance as a mainland user in 2026 requires navigating technical and regulatory nuances. By following this guide, you prioritize security, understand the funding pathways, and most importantly, you secure a permanent financial advantage through the referral discount. It transforms a routine sign-up into a strategic first move. In a market where every percentage point counts, starting with a 20% edge on costs is not a minor detail—it’s a cornerstone of savvy crypto participation.

Ensure your first step is the right one.
