I believe that people now know about these scam exchanges and stay away from them. Since the IEO appeared, these exchanges have listed a lot of projects, but none of them have been successful and have helped investors be profitable.
They are also the one that destroy IEO making it irrelevant compared to when IEO was still hosted by popular exchange only, these kind of exchanges are really stain of crypto world and should be get rid. The means is good enough to provide less popular coin a medium for exchange but the way they accept shitty project is what makes
most of us feels uncomfortable with them and making crypto market dirty.
