Are Airdrops still paying? YES they are but 99 percent of Airdrops won't worth your time, I Know it doesn't cost a thing to join Airdrops, you are only going to spend very few minutes on each Airdrop campaigns but why? For few pennies or a 1$ ? I'd rather take that chances with bounties instead.
That's right, if we look at the rewards given through the airdrop program, it is not really worth the time used by each participant especially if the gas costs at this time can sometimes be expensive suddenly, so joining the airdrop doesn't mean it's not good, it's just only the results are not commensurate.
But that's still free money. I remember my first Airdrop was not worth so much but its value blew up after a week. Its quite true that it might take your time but these opportunities are open and we must take them as we see them available. We also need to keep in mind that some airdrops are just phishing baits so we need to be aware on how to check legitimate Airdrops.
