Bitcoin fell to the critical $100,000 support level overnight as a stronger dollar and uncertainty surrounding Federal Reserve policy dampened risk appetite. U.S. spot Bitcoin ETFs experienced approximately $1.3 billion in net outflows over the past four days, contributing to the pressure on the cryptocurrency. Additionally, over $1 billion in long liquidations and options hedging pressure have added to Bitcoin's volatility, keeping it under short-term pressure. Analysts indicate that sentiment could improve if ETF flows stabilize and no new macroeconomic shocks occur.
