''The coin being just a digital currency, not tied to any far future projects or centralized companies, makes it instantly tradeable.'' However it's impossible for everyone to make money, someone has to lose money so others can profit.
''As the demand grows'' How is the demand going to grow exactly?
''If we created an open syndicate without the coin, what motivates people to act on the information, or even look out for each other?'' What will motivate people on your syndicate to look out for each other? Are you giving coins to people who participate in meaningful ways? Otherwise I don't see why or how this would work. Eventually the few enthusiasts that actually participate will get bored and leave.
And yes I'm extremely skeptical because it seems that everyone wants to involve ICOs and coins into their projects without any reason.
