I agree @acidyo.
When I got the link and signed up, I looked into it a bit more. Interesting project like many...I thought the $1 a bit far-fetched. My biggest problem is that many tokens are trying to be the world reserve currency to replace the USD...I dont think it will happen. There will be many tokens people use.
Nevertheless, I used up my referrals to build whatever I could from them. Like many projects, I look at them as little lottery tickets.
The fact you only have limited invites can be a good thing too, this way "popular" people that have a lot of influence won't get the biggest edge to anyone else. Could be good for a fair distribution.
