Personally, I do not think there is any bounty projects that will not care about listing because the joy of the project is to get listed  so as to attract investors and they will also make money from it but the reason why some do not get listed is maybe due to the fact that they do not have good support from the community, good team members or the token was not well developed but I believe if you have a very good token and hold for long term, you will earn profit from it.
