[Analysis: Bitcoin Falls Below $90,000, Institutional Investors Lead the Sell-Off] According to a report by Jinse Finance, Bitcoin fell below the $90,000 mark on Monday evening Eastern Time, reaching a new local low and its lowest level in seven months. "Bitcoin breaking below the $90,000 threshold during today's trading session highlights the current fragility of the market," said Rachael Lucas, a cryptocurrency analyst at BTC Markets. "Institutional investors are the main force behind the sell-off, and the outflow of ETF funds indicates that investors are taking profits and adopting risk-averse positions ahead of the year-end." "The long-term value of Bitcoin as digital gold remains unchanged, but short-term sell-offs by traders and leveraged players, as well as portfolio adjustments by funds, are putting pressure on the price," said Vincent Liu, Chief Investment Officer at Kronos Research. "Bitcoin falling below $90,000 is a short-term correction, with the $85,000 to $87,000 range serving as a recent support zone," Liu added. "Reclaiming the $90,000 level is crucial for buyers to rebuild confidence, especially with the current Fear and Greed Index at just 11, indicating that market sentiment remains relatively subdued."
