You can check out their documents, website, CMC, and social media, and you can finally judge whether this project is large and has a reputation or not:
I now get your point, i can see that they are listed on some 'big' exchanges, but that doesn't still make them trusted, neither does it ascertain that they are going to pay bounty participants on this forum, i for one do not even trust centralized exchanges, thus i'm not going to trust a project because they managed to get listed.
My conclusion does not mean that I am defending them; this is just what I discovered about them, and their success in distribution and payment in the end is what will determine whether my conclusion is correct or wrong.
I know you're not defending them, but just giving your own opinion. I agree with you on this one, we'd have to wait and see if they pay their bounty participants. The bounty manager's post in this thread somewhat indicates that there is no cause for alarm yet and that he is still in communication with the project owners, thus maybe the participants should be a tad patient.
