Trading volume across South Korea’s five major crypto CEXs (centralized crypto exchanges) reached approximately 31.1 trillion won, or about $23 billion, in the week from August 21 to 28, up 188.04% from 10.8 trillion won the previous week and the highest level in nearly 10 months since late October 2025. Upbit held 59.61% of the market, followed by Bithumb at 33.11%, while Digital X, formerly known as Korbit, rose to 4.21% and overtook Coinone at 3.05%. Separately, Upbit recorded roughly $1.04 billion in 24-hour spot volume and briefly reached 4.61 trillion won in daily turnover after Bitcoin moved above $80,000 in late August. The recovery followed a weak first half of 2026, when lower prices and activity reduced exchange revenue and profits, prompting smaller platforms to introduce fee waivers.
