Bithumb holds the largest cryptocurrencies among all exchanges in South Korea.
Last year, it held 2,657 million cryptocurrencies, according to its 2018 financial statement.
Korbit came next with 16.4 million cryptocurrencies. Korbit started a business in 2013 and held Bitcoin and Ethereum as its assets.
Upbit held 4.2 million cryptocurrencies—the third largest holding among the South Korean exchanges. Coinone retained 240,000 cryptocurrencies—the least holding among the four major exchanges.
The exchanges increased the cryptocurrencies most through fees they receive from buyers. They receive fees in cryptocurrencies when investors buy virtual currencies. However, the exchanges get fees in local currency when investors sell cryptocurrencies.
