Bitcoin fell below ,000 in early 2026 amid growing concerns over a potential U.S. government shutdown and escalating tariff threats, erasing billions in market value. The decline highlights the cryptocurrency's heightened sensitivity to macroeconomic uncertainties and geopolitical tensions. Investors are now closely monitoring U.S. fiscal policies and trade disputes as key risk factors for crypto markets. The move has intensified volatility in the digital asset space, with broader implications for risk appetite and portfolio allocations.
