Due to concerns over the bankruptcy of China's largest developer, Hengda Group (Evergrand Group), the prices of cryptocurrencies such as Bitcoin have plunged. Bitcoin traded at $ 42,618 (around 50.67 million won) in 21 days at 8:33 KST, a 9.87% drop from 24 hours ago, according to CoinMarketCap, a global coinage agency. Bitcoin, which was $ 47,000 the day before, plunged at 11am and is now down to $ 42,000. At the same time, Ethereum also brings in $ 2,948 (about 3.5 million won), 11.41% less than 24 hours ago. At the same time, the national cryptocurrency exchange Bithumb also sold 53.44 million won, down 7.8% compared to 24 hours ago. Bitcoin, which was valued at 58 million won the day before, has dropped since 11 a.m. and is now 53 million won. The sharp slowdown in the cryptocurrency market seems to stem from growing concerns over the Hengda Group's liquidity crisis. The debt of the Hengda Group is currently estimated at $ 300 billion (approximately 356.7 trillion won). This is equivalent to 73% of all non-performing loans (2.7 trillion yuan) of all Chinese banks. If the Hengda Group goes bankrupt, 1.5 million home sellers will directly hit it, and a chain shock for financial institutions is inevitable. Hengda Group is said to have clips in over 128 banks and over 120 other financial institutions. Fitch recently downgraded its investment rating to Junk (CC), saying the Hengda Group would go bankrupt on June 23 without paying $ 83.53 million in interest.
