There are some notable and good airdrops on last year like Arkham and on this current year which is on $WEN and $JUP which it did make out some
good free money.
As far as I know, Arkham is a good airdrop and unfortunately it didn't follow, so the free money is gone.
WEN and JUP might be the ones with FOMO right now but I'm not following them either because as far as I know, there are quite a lot of tasks to get the Jupiter airdrop token (JUP), including having to trade on Jupiter's DEX.
So effort is really needed on that programs since if they exert a lot of effort for sure they get rewarded.
This effort definitely has to be done because this effort is our way of getting gems from the airdrop.
I'm one of those who didn't make this effort because maybe I was lazy with airdrops, etc., but I'm currently focusing on the final exams for my campus. Maybe this is the right reason for me not participating in the airdrop.
