1. Identify scam signals
- Fake websites: Check if the URL is an official domain (e.g., 'binance.com' vs 'binancee.com'), be wary of phishing links.
- Unusual requests: If an airdrop requires a transfer, private key authorization, or downloading unknown apps, stop immediately.
- Exaggerated returns: Airdrops promising 'zero risk, hundredfold returns' are 99% scams.
2. Anti-scam strategies
- Verify identity: Confirm project authenticity through official channels (e.g., Telegram admin verification badge).
- Minimize permissions: Only grant necessary contract permissions (e.g., allow reading only, prohibit transfers).
- Use hardware wallets: Store large assets in hardware wallets, avoid connecting to unknown DApps.
3. Safe operational habits
- Backup mnemonic phrases: Save offline, avoid screenshots or cloud storage.
- Regular checks: Use wallet security tools (such as MetaMask's security check) to scan for unusual contracts.
- Small amount testing: When participating in a project for the first time, use a small amount of funds to test interactions, and expand operations after confirming safety.
Through the above three steps, you can efficiently capture quality airdrops while ensuring asset security, achieving steady profits in the crypto world!
