The airdrop value is quite good and rather easy to claim even if it may take 2 minutes. $5 in return is more than fair. The whitepaper is OK but we're missing the team and the sources. On the website are all 8 team members and advisors with additional info which is nice. However the use case is anything else than unique and they have a lot of competitors in that space but they have a MVP (minimum viable product) available.
