I don't know if this is scam or not. Anyway, the project didn't have any WP on start, then they showed something that looked more like a roadmap. There is no team. There is lack of data about tech part. There is only one exchange and it's crex.
If the team behind this project is decent they should understand that they didn't give enough info or achievements to build much trust, I'm afraid.
If it isn't... well, just the same.
