Seriously speaking, this is the exact thing that I am facing. I have participated in numerous projects, some of them even get listed but they don't distribute bounty tokens saying that it won't be distributed now. Some don't even list the tokens, they complain everyday about the market situation that they will list very soon and their "very soon" does not have specific time frame.
Well I also have these issues and I think every bounty hunter will face such types of bounty in his career. The best way to deal with is to ask the admin in their official telegram group and perhaps we can get an idea of when the distribution will begin.
Also we will come to know the views about the projects from the comments of other people in the telegram channel.
