I own some of the KCS as I am a user of the KuCoin Exchange but after few years I am still not convinced about this coin and feel that there are much better option. First of all it is worth to mention that the all uses cases are centred with KuCoin exchange so if you are regular user it pays off to hodl some of them to lower fees and get regular income for hodling. My main premise is that all the crypto above all should be considered as investment and with this in mind I feel that KCS is performing badly (esp. in bull market). Overall if you are not a Kucoin Exchange user I would avoid to hodl KCS and if you are a user of Kucoin Exchnage I would hodl only necessary amount of it (few dollars is enough).
