Jim Cramer has turned fully bearish on Bitcoin, with sentiment-tracking data showing him in 'perma-bear' territory. Bitcoin is currently trading in a choppy, range-bound manner between $81,000 and $93,000, with institutional Bitcoin ETFs showing outflows and the Crypto Fear & Greed Index indicating Extreme Fear. Traders view Cramer's bearish stance as a sentiment indicator rather than a fundamental forecast, anticipating possible volatility during the thin liquidity period around the New Year.
