[Saxo Bank: Bitcoin and Ethereum Decline as U.S. Stock Futures Fall] According to a report by Jinse Finance, Bitcoin and Ethereum have declined, while U.S. stock futures have also fallen due to ongoing concerns about the potential disruptions caused by artificial intelligence (AI). The U.S. stock market will reopen later after being closed on Monday for Presidents' Day. Concerns about AI have put pressure on tech stocks and other sectors, weakening investment appetite for risk assets, including cryptocurrencies. Investors are also awaiting the release of the Federal Reserve's meeting minutes on Wednesday, as well as the U.S. Personal Consumption Expenditures (PCE) Price Index data and fourth-quarter economic growth data on Friday. Saxo Bank analysts stated in a report: 'The key question this week is whether macroeconomic stability, particularly regarding the Federal Reserve's communication and inflation data, can reignite sustained capital inflows into cryptocurrency exchange-traded funds.' According to data from the London Stock Exchange Group, Bitcoin fell 0.8% to $68,279, while Ethereum dropped 0.7% to $1,984.
