Lots of persons do not know the difference between this two. Back in those days we always depend on minal task to recieve airdrops. Now adays, you need to work for airdrop to drop for you thereby interacting with the projects.
$0 Testnet usually works for those that are consistent enough that get the drop and it's free. And since its $0, I just move on if I don't get the drop because it cost me nothing.
Retroactive airdrops are usually for those who have money to cover a lot of tx and create volume.
What is your own opinion on this .
