There is a lot of room for growth still. Speaking honest I would say that the users are even more important once a project has launched. Investors are often only waiting to sell higher than what they bought for and go onto the next one.
I guess everybody plays of course an important role, but ultimately it's the users that drive the value of a platform.
Totally true, value is being driven by the users since they are the ones who uses the platform. I know in the future many users will use the platform because of the functionality and features.
Let them first develop the whole thing before you draw any final conclusions about the platform. They also need to iron out problems and bugs before it's working perfectly.
