Airdrops are making a comeback this year, with Arbitrum starting the hype, now many people are rushing to make transactions on Zksync net to be able to qualify for their airdrops, also the zksync main net is out days back, I guess we will see more airdrop actions this year.
Really, I am not a fan of altcoin so I don't know much about airdrops but the little I have read about airdrops is that their total waste of time since the payment is small and most of those coins never get listed on exchanges.
So only newbies who do have not much knowledge about the cryptocurrency market and are willing to waste time taking part in airdrops and bounties
