Airdops are worth joining. Apart from some bounties that allows low participants, I don't think bounties reply pay well these days. But for Airdops like tesnet and other related airdrops, I think the are worth joining, I recently participat in MON Protocol airdop on Memeland stakeland which I didn't spend a dime on. Just few retweets and I was given a good reward bigger than most bounties.
They are worth it if you hit the successful ones and you're able to cash them out. Otherwise, they're going to waste your time.
And the technique of most airdrop people is that they're joining as much as they can to maximize their earning potential and chance.
They won't settle just for one bet for an airdrop and wait for its release, no. They keep on searching for as many as they can be.
