Bitcoin has declined steeply, dropping below $90,000 and falling further to $88,129, its lowest since April.This drop is part of a broader cryptocurrency market downturn, driven by a major liquidation event linked to U.S.-China trade tensions and high leverage in crypto derivatives.Investor sentiment is shaken as ETFs see record outflows, and experts like Tom Lee remain hopeful for a faster recovery, despite increased volatility and bearish influences such as Donald Trump.
