The first rule in working on airdrops is not to expect too much, airdrops are not much different from giveaways, even now many development projects implement a random system so that users who work on tasks from start to finish are not guaranteed to get results in the end. Oooh you're talking about the tap2earn airdrop whose hype has now subsided, if you want to take the trouble in airdrops you have to be able to explore. From what I read and know, airdrops have many levels ranging from easy, medium, and hard, try to master all three but once again airdrops are not a guarantee. Sometimes you have to spend money and that's called "retro". Other types of airdrops such as Testnet and Running node, you have to explore them all if you want to know more about airdrops. If you just focus on tapping the screen, it feels like you will be left behind and not get any benefits.

Good luck
