Airdrops are all luck these days, and if it wasn't luck they would not be rewarding as they are. Zksync, layerzero could be having a token but due to super high speculation on those, even if they do have a retro airdrop, they will be having strict requirements.
Interacting with those protocols will require good amount of $ to be spent, and then again it doesn't guarantee anything. Best suggestion I can give is interact with dapps/protocols where you feel like doing so and leave rest.
It must be admitted that the current airdrop is indeed different from before,
I think everyone is aware of this so don't be surprised if you join the airdrop and get nothing,
it's better not to get your hopes up on the airdrop.
People are no more interested on airdrop because they have discovered that at the end of every efforts rendered it makes no return or anything yielding, we need more of trust in other to be able to refer the beginners into this hunting for airdrops because it will grant them the first avenue needed to start their learning background about cryptocurrency, there's much anticipated from airdrops than the incentive received.
