Bitcoin and Ethereum fall, US stock index futures fall

Bitcoin fell 0.8% to $68279, Ethereum fell 0.7% to $1984, and US stock index futures fell due to concerns about potential interference from artificial intelligence. The US stock market will reopen later after being closed for President's Day. Analysts from Shengbao Bank pointed out that this week's focus is on macro stability and the impact of Federal Reserve communication and inflation data on the inflow of funds into cryptocurrency exchange traded funds. Investors are waiting for the release of the minutes of the Federal Reserve meeting, the US Consumer Price Index, and the fourth quarter economic growth data.
