I don't follow so many airdrop airdrop, only some of which I belong and it's been very long since the first airdrop really pay and has a value of each token. In contrast to airdrop almost token now has no value. If the bounty I stay abreast though now are hard times for the bounty hunter.
There were many successful bounty campaigns, but not a single successful Airdrop. Airdrop is a waste of time.
