Pay attention and you will notice a surge in referral system-based waitlists for projects since the Arkham airdrop.
Don’t waste your time with them, especially the new ones that you never heard about before. they just farming engagement.
I’d bet on projects that have been building for a while now tho. ethermail is a good example. do not fade ethermail
Join here with my link, I’ve been watching ethermail for about a year now. airdrop is scheduled for Q3 this year.
