The best airdrop season has come to an end since 2017, only very few new projects that are well recognized in crypto space are reliable that is if they introduce airdrop Campaign like how Wazirx and Origin protocol did weeks ago, as for KYC requirements it's really not worth it because Airdrop rewards aren't always that much
Talking about 2017, you could drop anything dumb and it would have made money so no,,, this did not make it a good project at all. The good projects have always been the same: services that were running and had products with a community of users. They paid basically the same in 2017 and today. Stable, real, valid.
