As the subject goes, what could be the main factor?
Famous developer, Media reputation, MM... or Just technology itself?
So far, it seemed that marketing and market marking were the main factors...
Those are extremely mandatory to boost the price. Famous developers could help the highest support to new project. Suppose Harmony has famous developers. I believe is project idea and plans, because good project can funds rise or by own funds can run to apply. Medium Ides can success by good developers team.
