I don't think so. I have no connections to the dev team or any of the major investors, but I've spoken with the main dev through PM and they definitely have the highest intention on making this coin succeed. It's unfortunate that not a lot of people see it, but they have actually put a lot of effort into gaining trust in the community and into their features. As of right now, their efforts seem to be very under-appreciated.
Umm.. do you even know what you're talking about? What promises didn't they fulfill? And they updated on progress just yesterday. It seems you really need to go back and do some reading. Original post is a good start.
