$BTC Bitcoin (BTC) recently surged past $91,000, marking a significant breakout and the first higher high of 2025. This rally is fueled by strong ETF inflows, bullish on-chain metrics, and a weakening U.S. dollar. Analysts predict a potential 70–80% gain from current levels. However, some caution that demand momentum has softened, and ETF inflows have plateaued, suggesting the rally may need stronger support to sustain.
