U.S.-Iran warning resurfaces ahead of nuclear talks, further pressuring bitcoin and crypto markets

What to know : A resurfaced U.S. advisory urging Americans to leave Iran, originally issued in mid-January, is stoking fresh headline risk for already-volatile crypto markets. Bitcoin, which has been whipsawed by liquidation-driven selling and thin liquidity, is reacting to geopolitical news more like a high-beta tech stock than a safe-haven asset such as gold. With U.S.-Iran nuclear talks in Oman and tensions elevated, traders are likely to treat geopolitical headlines as catalysts for volatility rather than clear directional signals for crypto prices.
