South Korean cryptocurrency exchange Bithumb has launched its third annual dormant asset recovery campaign, revealing that unclaimed cryptocurrency holdings on its platform total 291.6 billion won (approximately $201 million). This represents a significant 34% decrease from last year's figure of 443.5 billion won ($306 million).
The decline follows a successful 2025 campaign in which approximately 36,000 customers reclaimed a combined 70.6 billion won ($49 million) in forgotten assets. Market fluctuations also contributed to the year-over-year reduction in dormant holdings.
This year's campaign targets 2.57 million accounts that have shown no login or trading activity for at least one year. Among these, the largest single dormant holding stands at 4.1 billion won ($2.8 million). Perhaps most striking is the account with the highest Bitcoin return rate, which reached an astonishing 61,106%, and the longest unclaimed account that has remained untouched for 4,380 days—nearly 12 years, tracing back to Bithumb's founding in 2013.
"Many customers remain unaware of the digital assets they hold or have left them unattended for extended periods," said Moon Sun-il, Bithumb's Head of Service. "We hope this campaign helps customers rediscover and utilize their valuable assets."
Bithumb first launched its dormant asset initiative in 2023 when unclaimed holdings totaled 267.3 billion won ($184 million). The figure surged in 2024 amid the crypto market rally before declining this year.
Bithumb maintains its position as South Korea's second-largest cryptocurrency exchange, with 2.42 million monthly active users (MAU) according to WiseApp Retail's July 2025 survey. This trails only Upbit's 4.53 million MAU. Bithumb's 24-hour trading volume stands at $383 million, roughly 45% of Upbit's $844 million.
Meanwhile, Upbit's operator Dunamu released its 2025 user statistics, revealing 13.26 million cumulative members as of December 22, with nearly 1.1 million new users added throughout 2025. Notably, 5.48 million Upbit users are in their 20s and 30s—representing 44% of South Korea's entire population in that age bracket.
Trading trends show Ripple (XRP) was the most traded asset on Upbit in 2025, followed by Bitcoin (BTC) and Ethereum (ETH). The platform's busiest trading day was January 9, when daily volume hit 20.86 trillion won ($14.4 billion)—more than triple the industry's average daily volume.
