#CryptoSecurity101 Security in the world of cryptocurrencies is not an option, it is a necessity. Too many users still lose their funds due to avoidable mistakes: poor management of private keys, clicking on phishing links, or using unsecured wallets. Education is the first line of defense. Enable two-factor authentication (2FA), store your passwords in a reliable manager, and prefer cold wallets for significant amounts. Decentralization brings freedom, but also responsibility. Do not let your ignorance be the flaw. Educate yourself, take action, protect yourself.
