🔐 Cryptocurrency Security Guidelines

1️⃣ Private Key and Seed Phrase Storage

• Never store private keys or seed phrases online (e.g., cloud storage, screenshots, messaging apps, etc.).

• It is recommended to use cold wallets (such as Ledger, Trezor) to store large assets.

• You can write down the seed phrase by hand and store it separately in a safe place, such as a safe deposit box.

2️⃣ Be Cautious of Scams

• Do not click on links from unknown sources (especially fake wallet updates, airdrop websites, etc.).

• Social engineering attacks are common with fake customer service, exchanges, or 'friend' recommended projects.

• Be wary of airdrop traps or fake token transfers to wallets to deceive authorization; please enable the 'whitelist' feature.

3️⃣ Diversify Asset Storage

• Do not put all funds in a single exchange or wallet.

• Hot wallets are for trading and small operations; cold wallets are for long-term storage.

4️⃣ Enable Two-Factor Authentication (2FA)

• All exchange accounts should enable Google Authenticator, avoid using SMS only (which can be intercepted).

• Regularly update passwords and avoid using the same password in multiple places.

5️⃣ Carefully Choose Investment Targets

• High returns often come with high risks; DYOR (Do Your Own Research) is the basic principle.

• Pay attention to whether the project has real application scenarios, team background, audit reports, and community activities.

6️⃣ Be Aware of Authorization Risks

• When using DeFi, NFTs, or new projects, be sure to check authorization details (approve).

• Regularly use Revoke.cash to check and revoke unnecessary contract authorizations.

🛡️ Final Reminder

• 'Not your private key, not your coins.' Remember that true control of assets comes from the private key.

• Information updates rapidly; it is recommended to regularly follow blockchain security-related communities and reporting platforms.
