Airdrop hunting is a very time consuming work. and the rewards often are very low. unless you are a investor and participate in those premium level blockchain airdrops which require you to use a blockchain, make transactions. hold NFTS, do Staking ETC ETC. only these kind of airdrops might earn you some profit
otherwise Free Airdrops are worthless.
If you know that then airdrops will take up a lot of time to do many tasks, so take your time if you really have free time, never rely on airdrops to get your main basically it will not cover your needs... You yourself know where the value of airdrops is sometimes unpredictable.
About the retroactivity that you mentioned like having NFTs, many transactions + bridging then it requires capital as well as taking high risks, it is an individual choice because free airdrops will always be there but those who participate more then it could be a small reward.
