Only so much can be done at a time, I don't know your background so forgive me if I'm stating the obvious to you but development takes a long time and is very very difficult to speed up.Yocko,
Bitcoin does have similar functionalities to the ones you mentioned above, some of which could scale better than the bigger blocks (but that is another discussion)
Instant transactions - https://lightning.network/
Private transactions - https://www.cryptocompare.com/coins/guides/what-is-mimblewimble/
Sub cent fees
A growing node network (not shrinking) - https://lnmainnet.gaben.win/
And an evolution roadmap -
My point here is to raise awareness not about the next hill, but the mountain which comes soon after. I think Dash Core are tackling the upcoming challenges quite well through their Business development and Evolution Development (Although the lack of a schedule is worrying). After the hill there is a mountain, we need to talk about that today so we are better ready for it. That mountain as I see it will be twofold, one the one hand bitcoin and on the other the regulators.
Dash's USP needs to evolve if Bitcoins USP is going to become more interesting.
DASH core are a team of over 60 now and working hard on the current goal. Once this goal has been achieved I cannot see them just stopping work, they will for sure be doing the next step of integration for DASH.
Take a look at all the features and roadmap, do you really believe the DASH team will stalemate?
IMO smart contract cryptos are a different category to digital cash. I strongly believe websites like coinmarketcap.com should be separating the categories. At the moment people are confused thinking its all the same technology, it is not.
