I believe that the development team deserves activity from the participants so that their project grows in the future. They did a great job to run such a big project! This is a good job!
I agree, the development team tried to make the project what the users will like, but I think that they should not dwell on this, because the bright future of the project lies ahead!
Do you think it's worthwhile for developers to raise additional funds to make the marketing program more massive and strong? For as many users as possible to learn about the project?
Advertising has always been the engine of any project. But the money that was spent on advertising, should justify itself. I do not know the entire financial component of the project and therefore I think that they should not now do another marketing stage.
I agree with you, in this case you need to know the measure, to know when you need to stop and look at the result, if this is not done, then the project can turn out to be a big minus very soon!
