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.
Try to check the coinmarketcap dude here
https://coinmarketcap.com/rankings/exchanges/reported/ you can see there the top 20 exchange over that site, perhaps those platform who belongs to that top 20 will
only survive base on my opinion. Though, Bittrex has been established here for a years.
