How to Protect Your Crypto Wallet – 10 Security Rules
According to Chainalysis, users lost $2.2 billion due to hacks and fraud in 2024. In 2025, the number only grew. Most losses could have been avoided by following basic security rules.
10 Security Rules
Enable 2FA on all exchanges
Google Authenticator or Authy – mandatory. Don't use SMS authentication – SIM cards can be swapped (SIM-swap attack). Save your 2FA backup keys on paper.
Use unique passwords
A separate password for each exchange and wallet. Minimum 16 characters: letters, numbers, special characters. Use a password manager (Bitwarden, 1Password).
Store your seed phrase offline
The seed phrase (12 or 24 words) is the only way to recover your wallet. Write it on paper or a metal plate. Never store it in phone notes, cloud storage, or screenshots.
Buy a hardware wallet for large amounts
Ledger Nano X or Ledger Stax – they store private keys offline. Recommended for amounts over $1,000. Only buy from the official Ledger website.
Check the URL before logging in
Phishing sites copy exchange interfaces perfectly. Look at the address bar: binance.com, not binanсe.com (with a Cyrillic character). Bookmark exchanges and only access them from bookmarks.
Don't click links in messages
Exchanges never ask you to enter your password or seed phrase via Telegram, email, or SMS. If you received such a message – it's 100% scammers. Only access exchanges from browser bookmarks, never from links in emails.
Use an anti-phishing code
On Binance and Bybit, you can set a unique code that appears in every genuine email from the exchange. If there's no code – the email is fake.
Restrict withdrawals by IP
On most exchanges, you can tie your account to specific IP addresses. Withdrawals from an unknown IP will be blocked.
Don't keep everything in one place
Distribute your funds: some on the exchange for trading, some on a hardware wallet. Don't keep more than 20% of your portfolio on a single platform.
Keep software updated and check permissions
Keep MetaMask, exchange apps, and your OS up to date. In MetaMask, review permissions and revoke unnecessary approvals at revoke.cash.
Most common attacks in 2025-2026
GHOSTBLADE (iOS exploit that steals crypto keys), phishing via Google Ads (fake exchange sites in top positions), fake MetaMask extensions in Chrome Web Store, scammers on Telegram posing as support.
