Some projects are not just ready for the market. Some of them are afraid of listing, because they know that their tokens will plunge if they should, so what they can just do is to wait until they have a good profit to offer and to build hype around the project. At this point, bounty hunters just have to learn how to wair.
How can you learn to just wait if the bounty campaign is the main income? if we are not paid, we will have nothing to eat. no need to wait.
