#CryptoSecurity101 is a basic introduction to cryptocurrency and blockchain security. It covers essential principles such as the secure handling of private keys, the importance of using cold wallets (offline), two-factor authentication (2FA), and how to avoid common scams like phishing. It also teaches how to recognize insecure smart contracts and how to validate transactions before signing them. Education in security is key, as cryptocurrencies, unlike banks, do not offer protection against theft. CryptoSecurity 101 aims to empower users to protect their digital assets in a decentralized and often vulnerable environment.
