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.
