In July 2019 this South Korean exchange, Oasis was established. This exchange, Oasis has in its 2 years of activity provided users with a very nice trading environment, though in Korean.
The trading volume on this exchange also depicts its liquidity and therefore with a trading volume of about $19 Million, it invariably means that this exchange is deeply liquid.
It is a centralized exchange hence the servers are located in one region. This focuses the security at a central point. Registration here is very easy though I didn't register due to the inconvenience incurred in translating each single page of the site. The languages supported are English and Korean. If you'd like to register, it's up to you, but just so you know, it was formerly called Baibit.
