#Whatiscryptocurrency Why security matters so much
In crypto, security is one of the most important lessons. Because transactions are often irreversible, mistakes can be costly.
Basic safety rules include:
​use a strong password
​enable 2FA
​double-check wallet addresses
​beware of fake websites and phishing links
​never share your private key or recovery phrase
​be cautious of “guaranteed profit” promises
A good rule is simple: if something sounds too good to be true, it probably is.
