I wonder if it's a scam, since the website appears to be broken and no development appears to happen. The team was accused of stealing source code of other projects.
Their own social media and twitter accounts only post about ICO and coin listing or general market news.

So, it kind of looks like a scam or they completely failed at their plans and failed again at being honest about it.
