More than likely, they used that to attract investors on this project. But why is it hard from the team's end to inform their followers what is happening or the real status of this project? They can just post a general announcement here even one time to let their supporters as well as investors know that they are still here and if they are still developing this product. I was interested to check also this project before because it really seemed promising. But if this will continue, no updates from the team, you know where this is going. And I hope it's not what I am thinking here...
They had a very active advertising campaign and a lot of investors during IEO. And I think that it is very important to continue to inform people about their achivements.
When the ICO took place, it all seemed to me that this could be one of the best and successful projects! But it seems to me that all efforts can be reduced to zero if the project is not implemented in the near future!
