A South Korean cryptocurrency exchange, Bithumb, accidentally sent Ksh. 5.16 trillion ($40 billion) in Bitcoin to users, causing a brief market selloff. The company apologized and recovered most of the funds, clarifying the incident was not a hack.

• Bithumb mistakenly transferred 620,000 Bitcoins ($40 billion) meant as a Ksh. 177 ($1.37) promotional payment.
• The firm recovered 99.7 percent of the mistakenly sent Bitcoin and covered the remaining loss with its own assets.
• The error caused Bitcoin prices on the platform to briefly drop by 17 percent.
