2 Options here.

1- (most likely) Project has / is being abandoned.

2- Dev has been contacted by PnD group and told to stay quiet and make it look like the coin is dead, so they can buy more, when they have the bags, the dev will appear say how hard hes working and such, probably give some BS about how he will make a deal or something to pump the price (maybe the old Azure addition) and then it will get pumped, group who bought at 3k will unload at 15k then the coin will die.
