This is happening with few good projects in crypto space but many failed to understand, they want their half cake quickly e.g bounty hunters, to say the truth it's not easy to be a developer, not all projects that failed are bad, they might not just meet their expectations
That is what I thought of Exscudo, it's been 3 years since they finished their ICO at that time. But until know they are still under development on their exchange, even though the ICO was a huge success AFAIK. I mean, it's not bad but I think that they are just postponing the exchange with slower update but I don't know since I am not a developer yet.
