To be honest DASH is a good and well-established coin in the market, I think that the coin has good potential. I once heard that in the development team there is a man who used to be a developer of bitcoin. Is that true or rumor ?)
This is Dash current dev-team :
https://www.dash.org/team/It could very well be that some of these developers have worked on the Bitcoin project in some way before (Bitcoin is a large project after all) and then made a switch to Dash at some point.
Also Evan Duffield (Founder of Dash) was first very interested in Bitcoin, but when he found out he could not make the Bitcoin developers add privacy elements into the Bitcoin project
(Bitcoin developers feared hard forks i guess or were just not interested in privacy at that time) he ended up creating Dash as altcoin and functioned as Dash Lead Developer for awhile.
He left the Dash Core Group in 2017 and created a seperate project named DashLabs where on-chain scaling applications and research is performed.
One use case came out of DashLabs so far :
