DASH has lots of really nice technology behind it, and some good benefits, but I think the main thing holding up the price is the masternode economics behind how it works
Without masternodes, there's no one who can be a real currency. It's the only thing that can make it useful for daily purchases. Double spending is a risk on non-masternode coins, really if people look at the realistic usability of each coin they would drop the leaders and take a MN coin.
