I see almost 30K volume on CMC summary for Atlant token but this is not true, I think.

Almost 20K is from Exrates exchange which is totally a scam and I advise to not trade there. There are hundreds of scam accusations on the internet against Exrates. This is enough to look at their order book to know that they are running a scam exchange with fake trading. They offer sometimes very good prices sometimes to catch greedy people who want to make fast money. If arbitrage opportunity seems to be amazing then double or even triple check everything because this is mostly an error or scam.

I think CMC should not list this exchange and take into consideration when counting volumes, etc. I don't know why such a good and established service is supporting scammers.
