If anyone was a part of a genuine airdrop when the market were in red and kept holding on to those tokens till the market went green they will make good profit. There is nothing to argue on that part. The problem is to find and track genuine airdrop. In the current market condition it will be hard to find one as there will be more scammers waiting to gain access to the wallet. Anyways it is always advisable to have two or three wallets only for airdrops.
airdrop nowadays if i remember correctly even the ones that are in the bearish market aren't really relying on the market trend I remember clearly back then when bitcoin still floating around $20k there was OP airdrop, arbitrum, and many more.
overall nowadays airdrop are changing method but also not truly relying on the trend.
its quite different if you compare it with back then where quite literally some airdrops just relying on market trend and decide to hold off from releasing their airdrop if they don't see the circumstance to be fitted.
i can be wrong about this though.
but i think its kinda easier tracking airdrop if you really want to put an effort just following some random telegram group sometime give sufficient information regarding airdrop. but just don't fall into the scam telegram channel where
they instead misled you into getting scammed by them though there are plenty.
