Be safe to know that there would be no airdrop for this project. You've got to do what you need to do right now to own some tokens or earn them when the app is fully launched. Your choice.
Dreamr project is a unique one with very limited ways to earn some tokens. One of the few ways is through the sign up bonus. I believe that the sign up bonus is Still active as users have the opportunity to earn some tokens after signing up on the website.
