Net profit at Dunamu, the South Korean parent of crypto exchange Upbit, dropped 73% to 160 billion won ($120 million) in the third quarter from the year-earlier period, CoinDesk Korea reported Tuesday.

And that's without any fallout from the collapse of crypto exchange FTX earlier this month, which occurred after the period closed. Upbit is the world's ninth-largest exchange by 24-hour trading volume, according to CoinGecko data.

"It seems that the continued decline in global liquidity and the overall contraction of the capital market have affected the performance," a Dunamu official said.
