Fundstrat Head of Research Tom Lee projects a substantial cryptocurrency rally extending through late 2025, supported by improved technical indicators and reduced leverage following the October 10 liquidation event—the largest in five years. Bitcoin and Ethereum have maintained stability with open interest at record lows, despite deleveraging pressures tied to U.S.–China trade tensions. Lee cited JPMorgan's acceptance of digital assets as loan collateral as a notably bullish signal for the sector.
