For me, KuCoin share (KCS) is the gem. Right now its market cap is only 1/10 of Binance coin. The quality of Kucoin exchange is on par with Binance, I would say. The only difference is volume. Binance has successfully gain a huge market share with over $1B daily volume.
I would agree if it had stop limits, without such features it'll never get the volume of Binance, it's the only missing thing as far as KuCoin goes.
DAG aka Constellation is the best gem on there at the moment in my eyes
