I don't think there is any guarantee about this.
New projects will be very profitable if they are really liked and will be profitable if they get hype everywhere. but on the other hand this can also be a blunder for ourselves because it is like gambling, especially for those who don't know how to choose a project.
Yes, because basically not all new projects can be good at first although some can be good in the end but that always happens when a project has passed a new challenge or competition with others.
