Theyre too busy with their development hiatus (aka sippin on margaritas at an island resort thanks to the millions made from ICO) to give a sh*t about updates right now. Hopefully they return. Or they're doing this on purpose for it to dump hard and get some cheap along with whales they might be working with. Not to sound like a conspiracy theorist, but do you realize how easy it is to control the price of a coin if you're a dev and also take advantage of this control? You can accumulate and then hype up some update anytime you feel content.
That's it!
Before the ICO they had all the time to hype. Now, as they get their money, they have no more time. This is really not fair!
Look at Tenx ICO. Before, during and after the ICO, their PR is always the same with very active support and updates on their social media.
You name sell your idea.
Any ico has the possibility to loss. face it
