From my own experience I can tell from all the airdrops that I know the top projects were only: Vite, Ontlogy, Dfinity. All others were shitcoins

I never got hold of that coins, because I stopped doing these airdrops coins, and people should do the same, it's only a matter of time before these airdrops become obsolete and people will not participate in these airdrops anymore it's just a waste of time.,
This is right, Airdrop is becoming obsolete and waste of time as it doesn't pays anymore. If Bounty campaign is turning into something else then the era of Airdrop is gone also.
