i just see them in CMC exchanges list and have a high 24h trading volume
so doesn't CMC Check on that before reporting??
Have you ever heard that CMC did faking volume?
Looking at the site's traffic which is still low compared to other exchange sites, I think that the volume listed in CMC must be incorrect but I'm not quite sure about it.
Looking at the official ANN thread, there is also so low number of users who reply or give review to the thread. So I dont recommend you to use it.
