Upbit launched in October 2017.  Kakao partnered with American exchange Bittrex to support stable virtual currency trading. This allowed them start trading with over 100 different altcoins.  At the time of their launch, this was the largest number of cryptocurrencies offered by a Korean exchange. 
On March 22, 2018, it was announced that Upbit developed UBCI (Upbit Crypto Index) , Korea's first cryptocurrency index. 
On Upbit, users are able to interact with the platform over their mobile device; this is similar to how users interact with Kakao's stock trading app, Kakao Stock . On the Kakao Stock platform, Korean cryptocurrency owners can trade digital assets within Korea's Kakao Talk messenger app.
