The main issue is that airdrops are not reliable. You can get a reasonable amount of money from a project you never expected, and you can get out with dust from a project you hyped. That's just the truth about airdrops, and you will never be certain of one if you get paid.
I missed on some airdrops that paid really well, like EIGEN, I also don't want to miss out on anyone again, but I will also not rely on them because they can disappoint. But if I get a reliable airdrop, I will participate because I am fed up with the dust rewards gotten from telegram tap to earn airdrops.
the hardest part of following airdrop always predicting the legit ones, EIGEN is rare occurrence, because they decided to go with tiered system and added bonus at the end of the TGE.
compare it with puffer finance for example, tiered system but really low rewards

. I've seen plenty of people staking few ETH, not selling despite reaching ATH for the sake of puffer and then holding until ETH go back to $2500 only to get rewarded with fixed tiered reward of 70 puffer which only equal to less than $35. crazy I know but it happens.
this is why I only consider airdrop just as a side hustle that might be waste of time and most of the time just hit or miss.
Yeah, without the needed resources allocated to it, you won't be able to get good rewards, usually. That's the nature of the drops currently in the crypto space for you and these people
Nobody says you can't try your luck and analysis, though.
