Many exchanges haven't been fair with their dealings with customers, so it is highly likely that they wouldn't survive for long. In my opinion, exchanges such as Binance, Bittrex, Poloniex and KuCoin will definitely survive for long.
Well even these exchanges you're talking about that's not being fair with their customers have a lot of dealings still. And they're drawing in a lot of money regardless of the market's state. Establishes and old exchanges have a higher survival rate than new ones since they already have their own folowing.
