Bitcoin is falling, and US stock index futures are also falling.

Bitcoin fell, and US stock index futures pointed to a lower open after Nvidia reported strong earnings but failed to impress the market. Jefferies economist Mohit Kumar said in a report that concerns about the return on artificial intelligence capital expenditures and the potential disruption of this technology to various industries continue to weigh on market sentiment. He said that since October, the decline in cryptocurrencies has been accompanied by a similar decline in tech stocks. "We believe that the link between cryptocurrencies and tech stocks will continue in the coming months." Data from the London Stock Exchange Group showed that Bitcoin fell 1.5% to $67,904, after touching a one-week high of $69,847 on Wednesday.
