I participated in the first airdrop IOP (internet of people) and with 500 token iop I received 2200 hydra .. that I sold in the exchange on the discord and from which I got 450 IOP .... with a gain of over 90% doing nothing. Tonight, the second airdrop closes the second airdrop and tomorrow another part
You just got lucky. Usually airdrops are complete waste of time, our only real resource in our possession.
99% of airdrops are made with the intention their 'devs' to make quick money.
Airdrop is not just for Dev making money. Airdrop is essential for currency to have diverse users. It's a case of entropy. You need different users from various countries and cultures to create an ecosystem around your project.
