I believe that Wait-list is the new airdrop meta in the industry.
With the success of ARKHAM INTELLIGENCE, so many projects are now going for wait-list.
You can do yourself a favor by trying to utilize all the wait-list you come across, though many will be scams, some won’t worth it, but just one win is enough to compensate you for the time wasted.
Also, try to get a dedicated email for your wait-list airdrops as well as a burner wallet, with this you will be able to isolate yourself from getting your wallet compromised.
