#CryptoSecurity101 is a mandatory lesson for every cryptocurrency user, regardless of their level. In an ecosystem where you are your own bank, security is not optional: it is vital. From using cold wallets and strong passwords to enabling two-factor authentication (2FA) and avoiding suspicious links, every action counts. Most hacks do not occur due to technical failures but rather human errors. Protecting your private keys is protecting your money. It's not enough to invest well; you also have to secure well. Education in security is the best investment you can make in crypto. Don't underestimate it.
