Bithumb, a major virtual asset exchange in South Korea, is currently embroiled in a significant scandal following an unprecedented mispayment involving Bitcoin. On July 7, during a promotional event aimed at acquiring new users, the exchange inadvertently distributed a staggering 620,000 Bitcoins instead of the intended total of 620,000 won to 695 participants. This catastrophic error occurred due to a simple yet critical input mistake where the denomination was inadvertently switched. As a result, the market value of the incorrectly paid Bitcoins reached approximately 60 trillion won, causing severe fluctuations in the trading price on Bithumb, which dropped to the low 80 million won range.
