Bithumb Fat-Finger Error: 2,000 BTC Mistakenly Credited, Triggering Local Flash Crash Brenda Mary | usagoldmines.com

TLDR

• Bithumb mistakenly credited 2,000 BTC to hundreds of users, triggering a flash crash.
• Bitcoin briefly traded 10% below global prices due to sudden localized sell-offs.
• Exchange reserves limited withdrawals, preventing larger-scale market disruption.
• Immediate action by Bithumb aimed to recover wrongly deposited BTC and stabilize trading.

Bithumb fat-finger error briefly sent Bitcoin prices tumbling on the exchange after a system mistake credited around 2,000 BTC (~$130 million) to users instead of the intended 2,000 KRW reward, triggering large sell orders and a local flash crash before prices rebounded.

Prices on Bithumb sank to roughly ₩81.1 million, far below other markets, before stabilizing.

Accidental Bitcoin Distribution and Market Reaction

Bithumb, South Korea’s second-largest cryptocurrency exchange, mistakenly deposited around 2,000 BTC into hundreds of user accounts.

Reports indicate a staff member intended to send a 2,000 KRW reward, but accidentally selected BTC as the currency.

Once the Bitcoin landed in user accounts, some recipients quickly sold it, likely anticipating recovery actions by the exchange. This sudden sell-off caused Bitcoin on Bithumb to trade nearly 10% below global market levels. 

The local market experienced a sharp liquidity shock rather than a broader Bitcoin decline. One-minute trading charts show a near-vertical drop, followed by a long downside wick, reflecting the sudden surge in sell orders. 

Arbitrage traders and automated bots quickly responded, buying BTC at prices significantly lower than those on other exchanges. The bounce back in price demonstrates short-term market corrections due to mispricing rather than a return of investor confidence.

Users on social media reported the flash crash in real time, noting the extreme volatility. The combination of human error, thin order books, and automated trading created a brief but dramatic market distortion. 

The incident highlights the speed at which operational errors can impact local exchange markets.

Exchange Reserves and Recovery Measures

Despite the massive credited amount, Bithumb’s actual Bitcoin reserves prevented full withdrawals. The exchange reportedly holds about 50,000 BTC, limiting the possibility of large-scale asset outflows despite system-recorded deposits far exceeding actual holdings.

More than 500 BTC were sold immediately, causing price disruption, but a broader market collapse was avoided. The exchange acted quickly by suspending deposits and withdrawals and inspecting servers. 

Bithumb confirmed that most wrongly deposited BTC could be recovered, although assets already sold or transferred overseas may be difficult to reclaim fully.

Regulatory scrutiny is ongoing, as Bithumb faces potential fines related to anti-money laundering compliance. The incident occurred amid volatile Bitcoin markets, emphasizing that centralized exchanges are single points of operational risk. 

Even minor errors, such as event reward distributions, can lead to rapid price swings and localized market instability.

The episode provides a clear example of how technical mistakes intersect with liquidity and trading behavior. While the immediate threat was contained, the incident shows the vulnerabilities that centralized exchanges face when internal controls fail.
