Airdrops have become one of the most common ways for new crypto projects to gain attention, grow communities, and reward early supporters.
It's nothing compared to years ago during ICO/Airdrops boom back to 2017-2018. Today, there not that much airdrop based projects as you may notice here in altcoins board because bitcointalk is a great indicator of those projects as most of them starts here since bitcointalk is the greatest crypto community ever. We used to say plenty of projects announced everyday with many campaign managers running their services in the Bounties sub-board. Today, too long time to see a new announcement for an airdrop based project.
This is absolutely normal since community knowledge has been growth over the years to know that 99,99% of those projects are scammy schemes.
