Currently, every third cryptocurrency exchange is launching its own currency to attract investments. The Chinese platform is no exception, and there is some benefit to this. I don’t consider passive income just for holding tokens – given the low trading fee and the fact that holders receive only a small share of the administration's profits, the dividends from the token are insignificant, there’s little benefit, and significant volumes are needed for this. Overall, the outlook here is not encouraging. However, a 50% reduction in trading fees looks much more attractive. As for trading itself: usually, internal coins lose value over time, but here the exchange maintains a stable rate by regularly buying back the asset, so the liquidity of KCS is good. Another source of passive income is the affiliate program – 40% of the referral fee – which is a decent offer. Although it won't generate a large income, having three referrals with similar trading volumes can almost cover your trading fees, allowing you to trade without costs.
