I think DASH is one of the game-changing altcoins that will stay on top together with BTC in the future.
People thought that LTC was at the second place, but I see no future for it. At least, it's a widespread altcoin, but DASH has all the key features to replace LTC.
I converted all my LTC into DASH in the last pump, and I'm so happy about my choice

Also I still mine DASH with my small rig.
