First mover advantage is an interesting point, but in my mind, nothing after bitcoin can be as "fair" as bitcoin. Think of it, now that we know cryptocurriencies work, they're assigned a value right out the gate. There are speculators and premines.. Every project is tainted by the promise of making big bucks.

When bitcoin was released, it was a toy. It didn't even have a real price until much later, and even then, people had no idea if it would "work" long-term.

This fairness needs to be intact for mass adoption. How many people really want to buy something that the owner premined 60% of the supply of, and effectively has all the control?
