Bitcoin extended Thursday's daily decline to 3% as President Donald Trump's comments about military action against Iran pressured US stocks. Bitcoin traded below $82,000 around the Wall Street opening. Trump reiterated the possibility of further military action and said the US was not negotiating with Iran. Renewed concerns about AI valuations also weighed on technology shares, according to BMO Capital Markets' Ian Lyngen. Bitfinex Alpha analysts forecast Bitcoin trading between $81,300 and $84,400 until the Federal Reserve's October 28 interest-rate meeting.
