0728 GMT - Bitcoin falls slightly as concerns about persistent tensions between the U.S. and Iran dent risk sentiment. President Trump said he is not seeking an extension of the 60-day U.S. ceasefire with Iran which expired Monday. He also threatened to bomb Oman as he claimed the Gulf nation might be standing in the way of a peace deal. Bitcoin falls 0.2% to $64,261, LSEG data show. Bitcoin holding near $64,000 despite geopolitical pressure, exchange-traded fund outflows and crypto regulatory uncertainty signals improving resilience, although it doesn't yet prove institutional demand has fully returned, Zaye Capital Markets analyst Naeem Aslam says in a note.
