there will be no such good airdrops as the arbitrum. I have not found anything interesting for a long time, most often the developers promise one thing and in the end the results are much different from the promised and not in a positive direction.I just don't spend time on them as they just don't make a profit, the good times with drops are over.
There will be another good airdrop like arbitrum. I meant you must also take a look at some projects which potentially releasing their own token in the future. There are so many people hunting these tokens.
I guess that if many of them gonna try to chase it. The next arbitrum gonna come in the future. Believe it or not.
