1. Dash's biggest advantage is its marketing. Which other cryptocurrency has so many youtube videos on explaining how it works, updates, interviews, etc.? And I think that is the right way to approach this topic if you want to make it accessible to new members. I don't think the 'best' cryptocurrency will win. In the real world, nobody win because he/she has the best and most efficient system. A large part will always be the brand.
2. There is a huge dependence on evolution, if the team doesn't deliver, Dash will have a major setback.
