1235 GMT - Bitcoin trades modestly lower along with U.S. stock futures as the prospect of a deal to end the Iran war dims. President Trump said he wouldn't seek an extension of the 60-day truce between the U.S. and Iran, which expired Monday, and threatened to bomb Oman. Markets are showing a more cautious tone as investors contend with rising long-term bond yields, renewed geopolitical uncertainty and some fresh nervousness around AI-related stocks, Capital.com analyst Daniela Hathorn says in a note. Bitcoin falls 0.1% to $64,274, LSEG data show.
