Split on the PR thing, (imho) Dash is way out in front of the crypto tech race and could slowly develop a rock solid user base on its merits alone, on the other there's a lot of smart folks coming up with new ideas by the hour and something could come along that changes the game completely so its best to strike while the iron's hot and get established right now. I'd vote for the latter but feel there's no need, Dash's innovations make it the highest valued coin out there regardless of what the markets may think.
The thing is you need a lot of publicity in order to make people believe in a product. No product ever stood on its merits alone.
Look at Warren Buffett for example who is an excellent showman and advertiser for his Berkshire brand. Steve Jobs was the same. There is no such thing as reality in peoples' heads but only perception of that reality. Something only exists if it is perceived. Stuff that you don't perceive doesn't exist.
