The video creation bounty is already closed, so what will be the next bounty? I don't think this campaign is successful because a lot of videos is not good.
The main reason for running this campaign is make awareness bro. So we cannot consider it is successful or not by ourself.
Yes, the reason of this youtube bounty is make awareness and also increase exposures and popularity of this project, so even the bounty was ended we cannot tell if the project will succeed or not. It needs time and more improvements.
