There are so many exchanges are going on with false traffic volume. I have gone with these exchanges and experienced some problems. Now I am going to tell one or two experienced with you. Baz token in etherflyer is not from traders it is false trading because there is no buyer and seller on the price they executed.when you trade their ongoing price will fail. Same case with p2pb2b exchange when I trade P2PS coin. Pgpay coin price is different from probit exchange.so today exchanges are really not doing great things.
