i think it can go up that much.
currently there are so many newcomers coming in bitcoin and investing a lot of money in it. soon after, many of them will start thinking about investing their bitcoin in other things like altcoins to make profit on it.
so some of them will buy DASH.

but it will be temporary as these newcomers understand how things work and dump coins like DASH to move on to more promising altcoins with a better pump to make more profit. everyone is greedy.
