It offers a chat window next the trading window which is officially named "TrollBox" by HitBTC, a fitting name I believe. This is the perfect place for pump & dump schemes.
HitBTC is promoted by MinerGate and it seems there's a cooperation between MinerGate, FreeWallet and Changelly, all of which don't have the best reputation, that alone wouldn't say much but for me there are too many yellow flags in this exchange. Be careful before trusting your money in them.
