Why Crypto Security Matters
Unlike banks, cryptocurrencies are self-custodied: you are your own bank. If you lose access or get hacked, there’s no way to recover your funds. Security is your personal responsibility.
- Irreversible transactions
- No central authority to restore lost funds
- High-value targets for hackers
- Rapidly evolving attack methods
Common Threats to Crypto Assets
- Phishing: Fake websites, emails, or messages tricking you into revealing private keys or passwords.
- Malware: Keyloggers, clipboard hijackers, and trojans targeting wallets.
- SIM Swapping: Attackers hijack your phone number to bypass 2FA.
- Exchange Hacks: Centralized platforms can be compromised.
- Social Engineering: Scammers impersonate support or friends.
- Physical Theft: Devices or written backups can be stolen.
Choosing the Right Wallet
| Wallet Type | Security | Best For |
|---|---|---|
| Hardware Wallet | Very High | Long-term storage, large amounts |
| Software Wallet | Medium | Everyday use, small amounts |
| Paper Wallet | High (if generated securely) | Offline backup, cold storage |
| Exchange Wallet | Low | Active trading, not for storage |
For maximum safety, use hardware wallets like Ledger or Trezor. Never store large amounts on exchanges.
