There are a few criteria that must be fulfilled:
1. No premine. Let people donate to the progression of the coin. Keep the donation address public, so that people can follow where their donated money go.
2. Make a clear plan for how the donations will be used, logos, giveaways, website, etc.
3. Make sure that there is no instamine, mining should be profitable, but not in a way that gives the early adopters a huge advantage. Try to keep a linear curve.
4. Make mining easy. There should just be a button to push, as simple as possible.
5. Prefarably a way to only allow solomining. What's the point with the pool hierarchies?
6.
7. Am i just talking nonsense here, or why are there no such coins?
