The mindset that's needed by a sucessful coindev is a love of minimalism and good security awareness.
So basically the opposite of ethereum? I feel like their devs would stop every so often while developing the concept and look around at each other and in unison say "needs more cowbell". And this continued for a very long time. It just seems overly complex, and not just a little bit, heaps. And it hasn't done them any security favors either.
