I took month's rest because of burned out doing these telegram- based airdrops, but I got back because I have friends who made a lot from doing testnets, there are money to be made from airdrops, and it's not doing tapping anymore.
There are so many things to consider when you are participating in airdrops. It's better to join airdrops where they are initially funded by big tech companies, use case and potentially longevity of the project.
Another consideration is allocation and the number of participants; you don't want to be in an airdrop when you calculate that you only get a fraction.
