There is no quick way to know a good airdrop until the team behind it is unveiled. I have seen so many airdrops that I know would never succeed, maybe ending up scamming their victims with poor allocation after so many promises. We should not expect too much from airdrop because many of these project devs are not considerate after so many promises. I have participated in so many airdrop and their are some that are impressive and their are some that give out poor allocation making investors to panic after taking their time to mine consecutively without anything tangible.
it is necessary to consider the airdrop you choose, because not all airdrops get commensurate payment, but in terms of people's different thoughts, even though they get auncommensurate reward,they still visit it, for the reason of having a lot of free time to spend it.
It will indeed be difficult to avoid the desire of many people to continue considering airdrops to work on them even though it is widely known that the results obtained are not according to expectations that are expected to happen.
But for those who do have time to work on it, it is not a problem, but not for those who do not have free time, because the work is quite time-consuming in my opinion, and cannot guarantee that what is done will produce results or even be the same as the bounty so far, depending on the owner of the project.
