#CryptoSecurity101 The security in cryptocurrency is a major issue in the digital age. Users must protect their assets against hacking, fraud, and human errors. The use of cold wallets (offline) is recommended for storing large amounts, while hot wallets (online) should be secured with two-factor authentication. Centralized exchange platforms remain prime targets for cyberattacks, hence the importance of choosing reputable players. Caution against scams (phishing, rug pulls) is also essential. Finally, ongoing training and individual vigilance are the best protections in such a dynamic universe as that of cryptocurrencies.
