Exchanges like p2pb2b, vindax, latoken, are Fake Volume, buying IEO Launchpad Tokens on Exchange like that is a big loss in my opinion
I always say that, that the exchange as you said above is very risky to lose money. Shady exchanges often display invalid coin volumes and many new IEOs are listed there and not many are successful. if you want to invest in IEO then choose IEO which is listed on the big exchanges like Binance, Kucoin or Bittforex.
