Here's a concise overview of **CryptoSecurity Fundamentals (CryptoSecurity 101):
**CryptoSecurity 101** focuses on protecting digital assets (like Bitcoin, Ethereum) from theft, fraud, and unauthorized access. Its core principles include:
1. **Private Key Security:** Your private key is your ultimate control. **Never share it** and store it offline ("cold storage" like hardware wallets) whenever possible. Losing it means losing funds permanently.
2. **Wallet Safety:** Use reputable wallets (hardware > mobile/desktop > web). Enable strong, unique passwords and encryption. Beware of fake wallet apps.
3. **Guarding Against Threats:** Be extremely vigilant against **phishing** (fake emails/sites), **malware** (keyloggers), and **social engineering**. Verify URLs meticulously and never enter seeds/keys online.
4. **Exchange Security:** Use exchanges with strong security (2FA mandatory!) but **don't store large amounts long-term** – they are hacking targets. Withdraw to your secure wallet.
5. **Seed Phrase Protection:** Your 12-24 word recovery phrase *is* your wallet. Write it physically on metal/paper, store multiple copies securely offline, **never digitally** (no photos/cloud).
Remember: **You are your own bank.** Constant vigilance and prioritizing self-custody security practices are non-negotiable in crypto.
