Imagine you had to send โน400 and you accidentally end up sending โน40,000 crore instead. Thatโs exactly what happened at South Koreaโs second-largest crypto exchange, Bithumb.
๐ช๐ต๐ฎ๐ ๐ฒ๐ ๐ฎ๐ฐ๐๐น๐ ๐ต๐ฎ๐ฝ๐ฝ๐ฒ๐ป๐ฒ๐ฑ?
- The exchange intended to send a total of 620,000 won (about $423) as prize money to 695 customers during a promotional campaign.
- But due to a human input error, an employee entered the value in Bitcoin instead of Korean won.
Result?
Instead of 620,000 won, the system credited 620,000 Bitcoins worth roughly $42 billion.
- These Bitcoins value equalled around 14 times more Bitcoin than the exchange itself owns.

- Bithumb froze the affected accounts within minutes and they have corrected 99.7% of the erroneous credits by reversing internal ledger entries.
- But 35 minutes before accounts were frozen, 86 customers managed to sell around 1,788 Bitcoins.
- This triggered a brief price drop on Bithumbโs platform
- Some funds were withdrawn to personal bank accounts while some purchased other cryptocurrencies.
- Platform is now having one-on-one persuasion talks with customers who cashed out, asking them to return the won equivalent voluntarily.

- This security lapse highlights the regulatory bottlenecks in Financial System.
- A transaction of this scale should ideally trigger automated red flags and dual or triple verification checks.
- It shows that though most of things are now digitised but humans still sit behind those systems and a single error could lead to unreal consequences.
This type of mistake has happened before also. In April 2024 Citigroup, a US bank, mistakenly credited $81 trillion, instead of $280, to a customer's account.
We need to have a financial infrastructure which has -
1) Stricter regulatory oversight
2) Automated system controls
3) AI-driven anomaly detection that can flag or freeze abnormal transactions.
