In these platform i always see topics that says they are gaining nothing through airdrops, and in airdrops you are supposed to gain something. i have never been to an airdrop myself so i could never tell. what is wrong about all this airdrops right now? is it now all fraud or there is something bugging the system or something else please tell me your knowledge about the topic.
Thank you.

Some airdrop are intended for free promotion , giving you no value coin. Some collect information from the supposed victims who participated in some scam airdrop via collecting their information thru KYC, you gain something sometimes but most of free airdrop are useless coin with no value.
