At this point if youre not concerned or dont see any red flags than youre an idiot. This ICO ended in the summer and it still isnt on an exchange. Not even crap exchanges. Something is wrong but your greed isnt allowing you to see it. If December comes and theyre still making excuses you know you've been had.
The fact that it isn't on an exchange yet doesn't make it a scam. We know that it CAN'T be put onto an exchange until the new blockchain is ready and the creation of a new blockchain was always going to take time.
What will make it a scam is if the devs disappear and progress stops.
But that hasn't happened so far.
And i'm not convinced that the lack of company structure makes it a scam either.
Even with the lack of detail around the who is behind this project it's still possible for this coin to be successful.
