Coming at things from a different angle - likely not the one you're thinking. But if you invest time in spaces that are innovative and have real utility on chains with low fees like base, sol and polygon you might find yourself getting an airdrop every once in a while.

I remember getting a jup (Jupiter dex) airdrop a while ago just from using the site a few times it's something to consider but it might not be worth spending too long on it - just if a crypto related site doesn't have its own token yet and is used a lot that might be an opportunity to see if you can wait for the announcement of a new token and buy low once the price has settled or try to connect your wallet and do a few transactions before the airdrop is announced. Due to high fees on the Ethereum chain I wouldn't suggest doing it there and make sure you verify how well sites are used on places like dappradar to ensure they're not malicious fakes - if you don't know what you're doing at all and don't think you can learn it it might be safer to find a different method.
