#CryptoSecurity101 Crypto Security 101 – Basics of Security in Cryptocurrencies

1. Private keys = Your gold

• A private key is a password that allows you to control your cryptocurrencies.

• Never share it with anyone and do not store it online in an unencrypted form.

• If someone obtains your private key, they can steal your funds.

2. Cryptocurrency wallets

• Hot wallets (online wallets, e.g., MetaMask) – convenient but more vulnerable to attacks.

• Cold wallets (offline wallets, e.g., Ledger, Trezor) – safer, ideal for storing large amounts.

3. Two-factor authentication (2FA)

• Always enable 2FA on exchange accounts and wallets.

• It is best to use an authentication app (Google Authenticator, Authy), not SMS.

4. Caution with links and phishing

• Do not click on suspicious links and do not provide information on unknown sites.

• Use official websites and applications.

• Check URLs to avoid fake sites.

5. Backup and security of seed phrase

• Seed phrase (12/24 words) is the key to recovering your wallet.

• Store it offline and in several secure locations.

• Do not write it down in digital form to avoid theft.

6. Updates and software

• Regularly update wallets, systems, and security software.

• Avoid using unknown or suspicious applications.

7. Be wary of scams and fraud

• Do not trust offers of “guaranteed profits.”

• Check the credibility of projects and individuals.

• Always pay attention to reviews and ratings.
