Participating in cryptocurrency airdrops can be exciting, but security is paramount. Never share your private keys or seed phrases; legitimate airdrops will never ask for this. Always verify the source through official channels like websites and social media. Be cautious of fake tokens and avoid connecting your wallet to suspicious sites. Review URLs meticulously. Do not fall for requests for advance payments. Using a dedicated "burner" wallet for airdrops adds an extra layer of security, protecting your main assets. Stay alert and remember, if an offer seems too good to be true, it probably is.
