Usually we have airdrop campaigns for projects that are new in trying to gather their community.
But, I'm worried about airdrops because usually the community that joins through the airdrop is one person in many accounts,
they could be one person with 10 telegram or twitter accounts.
It seems that airdrops may only work to increase membership in a group or social media followers.
I think they should also have a special event that at least the event is in their own community so that their community can really live.
An example like an AMA is probably a good thing, I believe you are better off creating an event
like an AMA by working with the exchange community to build a community because they are real people for your project community.
