South Korea's second-largest exchange, Bithumb, recently made an interesting discovery—among their 2.6 million accounts, there are actually 291.6 billion KRW (approximately $20.18 million USD) in "sleeping funds."

How did these funds become idle? It's quite an intriguing story. Bithumb launched a campaign to clean up dormant accounts, targeting users who haven't logged in or traded for over a year. As a result, they found some accounts that hadn't been active at all, with time spans exceeding 10 years. In other words, some of these funds have long been forgotten in the corners.

The largest single dormant position is about 2.84 million KRW. While this amount may not seem particularly large on its own, the total scale is quite significant. This also reflects a phenomenon: in the development of the crypto market, many accounts may have been sealed away for various reasons—changing platforms, forgetting passwords, or simply giving up—all sorts of reasons.

This incident also serves as a wake-up call for exchanges. How to handle the assets in these "ghost accounts"—balancing user rights and risk prevention—is indeed a question worth pondering.
