Yea KCS definitely has a lot of room to grow. KuCoin is now consistently within the top 25 exchanges. If it can break into the top 5 exchanges then the daily volume will be massive compared to now.
They are also constantly listing new coin trading pairs. They JUST released XRB and POE yesterday and they are already adding a new one CanYa (CAN).
I posted about CAN here https://steemit.com/bitcoin/@icantgoogle/kucoin-adding-canya-can-token-free-eth-and-can-promotion
