Crypto Security Best Practices

How to Protect Your Cryptocurrency

Protecting digital assets is about layered defenses: strong authentication, clean devices, careful signing habits, and privacy. Adopt the habits below and you’ll neutralize most common threats.

1) Strong, Unique Authentication

  • Unique passwords for every service: Use a password manager to generate/store 20+ char random passwords.
  • Prefer app-based 2FA (TOTP): Use Authy, Aegis, or Google Authenticator rather than SMS (SIM-swap risk).
  • Security keys when supported: FIDO2/WebAuthn (e.g., YubiKey) adds strong phishing resistance for exchanges/emails.
  • Recovery hardening: Store backup codes offline with your other disaster-recovery materials.

2) Anti-Phishing & Link Safety

  • Type, don’t click: Use bookmarks for exchanges and wallets; avoid ad links and unsolicited DMs.
  • Check domain & TLS: Exact spelling, expected TLD, valid HTTPS. If anything feels off, bail out.
  • Zero seed sharing: Your seed phrase/private key is never required by support, ever.
  • Beware “urgent” language: Countdowns and scare tactics are classic social engineering.

3) Device & Browser Hygiene

  • Update everything: OS, browser, wallet apps/firmware. Many attacks rely on old bugs.
  • Minimal extensions: Dedicated browser profile for wallet actions; remove unnecessary plugins.
  • Malware defenses: Use reputable AV on desktop, limit sideloading on mobile, and avoid cracked software.
  • Clipboard awareness: Double-check addresses on a hardware wallet screen before sending.

4) Wallet Practices That Save You

  • Hardware wallet for size: Confirm amounts and recipients on the device screen; reject anything unclear.
  • Segment by purpose: Separate wallets for trading, NFTs, and long-term holdings; keep hot balances small.
  • Review approvals: Periodically revoke stale token approvals and disconnect unused dApps.
  • Test sends: For large transfers, do a tiny test transaction first.

5) Privacy & Exposure Management

  • Don’t flex balances: Public bragging invites targeted scams.
  • Separate identities: Use different emails and handles for exchanges vs. socials; consider aliases.
  • Travel mode: When traveling, reduce on-device wallet exposure or carry a low-balance hot wallet only.

6) If Something Feels Wrong (Quick Plan)

  1. Stop signing. Disconnect wallet/extension.
  2. Move funds from the affected wallet to a fresh, secured wallet (hardware if possible).
  3. Revoke suspicious approvals; rotate passwords and 2FA on related accounts.
  4. Scan devices; update firmware/software; restore from clean backups if needed.
  5. Document what happened (links, txids) for any exchange/support reports.

Summary

Use unique passwords with app-based 2FA or security keys, keep devices clean and updated, treat links with skepticism, and segment wallets by purpose. Small habits dramatically reduce risk.
