The reason for this is imo, that Dash promised a lot and a lot of projects started, but one has the impression that none of those really found it's end.
For instance darkmixing. For how long now is this feature available now? A year? Recently i used it for the first time and was SO dissapointed. It took me 2 (!) days to mix 1000 coins. Unbelievable! Who do expect to use that stuff when everything takes so long? I know its a solvable issue. But ffs its been a year now! Same goes for masternode blinding etc.
You got to finish things first before moving ahead and open new projects.
