I have no idea about CoinEX but apart from Binanace most of the exchange tokens are yet to reach their full potential I have always suggested to go for Huobi Token, KCS, GT, Sushiswap and Uniswap as these exchange token can follow the path of Binance and even if they hit $100 still you will get multi fold profits. Especially when you are looking for long term then go for these instead of trying out any new exchanges
