On February 6, a system error at South Korea’s Bithumb exchange triggered a localized Bitcoin flash crash. Approximately 2,000 BTC was mistakenly credited to user accounts, leading to over 500 BTC being rapidly sold and causing prices to plunge over 17% on the platform. The incident was contained to Bithumb, with global markets remaining stable, and highlighted risks from internal exchange failures.
Bitcoin prices on South Korea’s Bithumb exchange plummeted over 17% in a sharp, short-lived crash on February 6. While alarming, the disruption was confined to that single venue as global exchange prices remained comparatively stable.
The incident stemmed from a computer error during an internal process that mistakenly credited roughly 2,000 BTC to hundreds of user accounts. This was a classic system input failure, not a deliberate transfer.
The credited balances existed only within Bithumb’s internal ledger and were not backed by sufficient on-chain reserves for withdrawal. The exchange’s actual holdings are estimated at around 50,000 BTC, preventing a full-scale bank run.
Recognizing the error, some users quickly sold their credited Bitcoin, dumping an estimated 500 BTC into the order books. This sudden sell pressure overwhelmed local liquidity, causing the dramatic price drop.
Exchange netflow data shows a sharp spike in Bitcoin outflows from Bithumb during the event, with a netflow of roughly negative 3,000 BTC. There was no corresponding sustained selling pressure on other major global exchanges.
The episode was a clear local dislocation driven by an internal balance error and forced selling. It underscores how operational failures at centralized exchanges can create sharp, isolated market shocks.
