Bitcoin BTC fell by about $100 to $77,351 just before noon ET after U.S. President Donald Trump announced that he had cancelled a trip by Steve Witkoff and Jared Kushner, who had been scheduled to attend the Iran-talks. The move comes after Abbas Araghchi, Iran's foreign minister, left Pakistan amid disappointment over near-term discussions. The decline in BTC was limited, suggesting markets view it as a short-term risk signal rather than a significant change in outlook.
