It is still a long way for the ICO sale to happen right? For now, the development team are working on attracting people and members for the site have bigger traffic impression. So the airdrop campaign is a good way to gain supporters.
Well airdrop is realy a great way to earn some stakes but remember that theres alot of scammers who takes advantage of the airdrops and they can easily earn tokens just vy registering multiple eth address and accounts.
I'm not sure what scammers do you mentioned to but I have seen a lot of people enjoying the airdrop and the bounty phase without no problem.
