As a KuCoin Exchange user, I hold some KCS, however after a few years, I am still not persuaded about this coin and believe there are many better options. To begin, it is worth noting that all use cases revolve on the KuCoin exchange, therefore if you are a frequent user, it pays to hodl some of them to save costs and earn a regular income from hodling. My fundamental concept is that all crypto should be seen as an investment, and with this in mind, I believe KCS is underperforming (esp. in bull market). Overall, I would avoid hodling KCS if you are not a Kucoin Exchange customer, and if you are a Kucoin Exchange member, I would just hodl the minimum amount.
