The Bank of Korea is advocating for the introduction of stock-market-style circuit breakers on domestic cryptocurrency exchanges, a move intended to enhance market stability. This recommendation is part of the forthcoming Digital Asset Basic Act and follows a notable incident at Bithumb in February, where a promotional error led to the distribution of approximately 60 trillion won (about $43 billion USD) in phantom Bitcoin, resulting in a 17% drop in Bitcoin's price on the exchange. The proposed circuit breakers would automatically halt trading when prices fluctuate sharply or when abnormal orders occur. However, the effectiveness of such measures is under scrutiny, given the global nature of Bitcoin trading, which allows it to continue on other exchanges even if one halts trading. Currently, major exchanges in South Korea, including Upbit and Bithumb, employ high-speed matching engines with built-in safety checks. The Bank of Korea's initiative reflects a growing concern over the volatility and operational challenges within the cryptocurrency market.
