That represents a monthly decline of about 43.5% from the early June level. The five-week sequence also shows that the slowdown was not limited to one weak session.The latest total is the lowest weekly reading in about two years and nine months. The previous sub-KRW 10 trillion figure came in late September 2023, when volume reached KRW 9.6 trillion. Digital Asset compiled the figures using activity from the five largest one-based platforms.Korean crypto trading volume has now contracted across several consecutive measurement periods. The sustained decline points to fewer transactions and less frequent portfolio rotation. Lower activity can affect how quickly orders move through local markets. Large trades may face wider price gaps when fewer buyers and sellers are active. Exchanges can also earn less from transaction fees when turnover falls for several weeks.Upbit Loses Market Share as Bithumb and Coinone AdvanceUpbit kept first place with a 63.02% share of South Korea crypto exchange volume. Its share fell by 3.95 percentage points from the previous week. The decline did not threaten its lead, but it reduced the gap with its nearest rival.Meanwhile, Bithumb increased its share by 2.38 percentage points to 29.51%. Coinone also gained 1.46 percentage points, taking its market share to 6.66%. Those shifts absorbed most of the share lost by Upbit.Korbit accounted for 0.78% of activity, while Gopax held only 0.03%. The rankings stayed unchanged despite movement in each platform’s share. Upbit and Bithumb still controlled more than nine-tenths of won-denominated exchange turnover.South Korea crypto exchange volume remains heavily concentrated in those two platforms. Changes at either exchange can therefore strongly affect national totals. Smaller operators also face a narrow pool of active traders during slower market periods.The latest figures show market share moving inside a shrinking pool. Bithumb and Coinone improved their positions, yet overall Korean crypto trading volume fell sharply. Their gains reflect relative performance rather than broad market expansion.South Korea crypto exchange volume closed the period with the same ranking order. Upbit led Bithumb, Coinone, Korbit, and Gopax, while total turnover stood at KRW 9.9676 trillion.The post South Korea Crypto Exchange Volume Drops Below KRW 10 Trillion appeared first on Blockonomi.
