Reasons for tonight's BTC crash: 1. Nvidia's plunge dragged down cryptocurrencies. 2. Gold, A-shares, and Hong Kong stocks all fell, creating a ripple effect. 3. US October CPI was higher than expected, and core inflation was also strong, a major negative factor. 4. Spot ETFs saw net outflows of over $1.3 billion in the past week. 5. Following the Binance hack, hackers continued to sell BTC, ETH, and other cryptocurrencies to cash out.
