According to Fox News, the Iranian supreme leader has rejected former President Trump's call for 'unconditional surrender.' This move escalates geopolitical tensions in the Middle East, which historically lead to increased volatility in the cryptocurrency market as traders often seek safe-haven assets such as Bitcoin (BTC) during periods of global uncertainty. Crypto traders should monitor BTC price action closely, as heightened conflict risk may drive up demand for decentralized assets. Source: Fox News (@FoxNews, June 18, 2025).
