Many users lose their funds not due to mass hacks, but because of basic security mistakes. Always use two-factor authentication (2FA), avoid reusing passwords, and never share your private keys or seed phrases. Use cold wallets for long-term storage and hot wallets only for transactions. Remember that if you do not control the keys, you do not control your assets. Do not trust airdrops or giveaways that require upfront investments. The best investment in cryptocurrencies starts with their proper protection.
