KuCoin

KuCoin's claim to fame is simply the vast array of coin pairings that it offers. Exchanges often gate-keep listing tokens on their exchanges behind massive fees or demanding requirements that make projects getting small, niche, or emerging tokens listed a near-impossibility. 

Although KuCoin's policy is not an open door, and while the exchange is serious about its vetting, it has far lower demand than other exchanges. It is willing to list coins with much smaller market caps. It is the best place to find more arcane and 'random' tokens while maintaining the CEX experience.

KuCoin is a global exchange, but it is not listed in the US. The features like phone support that you might expect from a standard corporate operator are also not here. KuCoin, although a professional, upstanding exchange that people trust, is still a little more of a wild west in terms of crypto exchanges when it comes to the tokens on offer and the user experience. For many, that's precisely why they love it.
