As a trader, would you be concerned if Mark Zuckerberg owned more than 5% of the shares of his company? How about Steve Jobs? In the case of Dash,
does Evan Duffield own too much Dash?
In general, a founder owning a large portion of the supply of anything does not invalidate the idea, though possible economic nuances exist relative to how much the large portion is. Like companies, my focus is how is the idea moving forward and is it moving forward over how much the founder has. Still, Evan recently stated how much he owns of the supply, which is less than Satoshi "supposedly" owns of the bitcoin supply (I think this 1+ million is debatable).
you are comparing apples with oranges.
Mark Zuckerberg, Steve Jobs, and Satoshi didn't create Facebook, Apple and bitcoin to make money! they were visionaries set out to change the world by offering something new. and they ended up making a lot of money by their project which they put a lot of effort into.
in case of altcoins in general including Dash, they are created with one goal in mind: make money the more the better. so they are going farther and farther from innovation and being useful and getting closer to becoming hype and pumps and dump. in which case when you own a lot of the shares you dump a lot more and make millions easy then you either buy back all up with 1/100 profit or give it up and move to the next altcoin premine.
