Without any doubts, exchange tokens are representing a raising trend, but to be honest, I do not believe that any exchange token will get to Binance level. Those guys are far too good and do not have real competitors at all.
Even the existing exchange tokens such as the Binance Coin and the Huobi Token looks overpriced for me. For example, the market capitalization of the Binance Coin is several dozen times its annual profits. Here the investors are assuming that the operating profits for Binance will increase sharply year after year. And there is a good chance that their expectations may not realize.
