For some reason, I have my faith on Bittrex.
But everyone is talking about coins and ICOs but I tend to believe most of the exchanges will be closed soon.
An exchange is a hell of a thing.
In my own opinion, exchangers or market can always survive depending on its reputation because some of the exchangers are stealing the coins of investors when the price of bitcoins really go up in a very huge amount and they will just claim it as a hacking allegation.
