Well, Ethereum got a nice boost when they got endorsement from Microsoft but its not focussing
on all the digital properties of money (transaction speed, transaction privacy, fungibility, decentralised voting and budget)
like Dash is doing.

Instead it seems to be more of a platform for developers where others can create applications that they can then run on top of it.
So i consider Dash and Ethereum two totally different projects and both have space to grow in their own niche.

edit : with perhaps Ethereum operating in a much bigger niche than Dash...
