Bitcoin (BTC) dropped approximately 2% during the U.S. session, influenced by two key factors. South Korea's benchmark Kospi stock index plunged 11% due to a tumble in chipmaking stocks, sending shockwaves across global risk assets. Additionally, the U.S. Senate shelved the Crypto Clarity Act, prioritizing a Russia sanctions bill and federal nominations, making the bill's fate uncertain for the year. The market is also anticipating the U.S. Federal Reserve's interest-rate decision on Wednesday.
