Well, I don't believe that a social movement has to have a formal organization behind it and this is proven by Bitcoin right now. or we can say that Bitcoin is a decentralized social movement...that can be the right term. Now, if the idea is to have an organization behind it because it is a social movement, that will be against the very idea of Bitcoin itself so in other words it would be a contradiction in itself. Bitcoin succeeded because of the people who believe on it and this will be the same throughout its existence.
