The Kucoin Shares Token is the integral and native token for the Kucoin exchange used primarily to cut trade fees and for the development of Kucoin by it's developers. I have been holding the KCS token for the past few months and have been receiving daily returns according to my number of held KCS which makes it my best part of the token as I could earn passively depending on my tokens held. Just like the primary tokens of many other exchanges, KCS can be used to cut trade fees but by a mere 20% for the Level 0 users or traders.
As of now, the value of the KCS is really undervalued and keeps depreciating in price but despite that, with many new innovations and more use cases coming it's way like the KuChain and other services that will be requiring the KCS for use in development, it will be a very valuable gem to hold on to. It's versatility even when it will be migrated to KuChain makes it easier to hold. Although plans for the token are really slow paced, much is to be expected
