OP is talking about CoinEx, not Coinexmarket.
The latter is a scam indeed, but CoinEx is a very legit exchange, with huge funding and the best mobile app in the industry.
I hold a lot of BCH so I use it a lot (since withdrawing for BCH users is 0-fee) but I think that 0.1% fees on trades are a bit high. Good news for CET holders, however.
I used to hold 500,000 CET, but sold it to ride the Zilliqa pump.
