Before entering the crypto trading world, account security is the first line of defense. Many people rush to buy coins but overlook the most basic protection — an insecure account means all trading strategies are useless.

**Level 1: Account Registration and Verification**

Registering with an email is much more stable than using a phone number. Never set your password casually; it should be at least 8 characters long and include uppercase and lowercase letters, numbers, and special symbols. Completing identity verification (KYC) is mandatory, including uploading the front and back of your ID card and facial verification. Only then can you unlock core features like fiat trading and withdrawals.

**Level 2: Hardcore Operations to Prevent Asset Loss**

Enable 2FA authentication, with Google Authenticator as the priority. Do not use SMS verification — text messages are too easy to intercept. Bind your account to your commonly used devices, and immediately disable login from unfamiliar devices. These seemingly troublesome steps are actually insurance for your assets.

**Level 3: Wallet Address Management**

Whitelisting withdrawal addresses is your second firewall. Only add wallet addresses you fully control — a single mistaken transfer can result in thousands of dollars lost. Keep spot and futures accounts separate, transfer large assets directly to cold wallets, and only keep funds needed for short-term trading on the exchange. Even if the exchange encounters issues, your main assets remain safe.

Get these done before entering the market, so you can buy BNB, BTC, ETH with peace of mind later.
