The analysis forecasts a significant downturn for Bitcoin, termed a 'crash,' scheduled around December 19th, driven by an anticipated interest rate hike from the Bank of Japan. Historically, previous Bank of Japan rate increases have correlated with substantial Bitcoin price depreciation. Specific instances cited include a 27% decline in March 2024, followed by 30% drops in July 2024 and January 2025. This pattern suggests a recurring adverse reaction in Bitcoin's valuation following such monetary policy adjustments in Japan. Projections from various sources indicate potential Bitcoin price targets ranging from $70,000 to $60,000, with some warnings extending to $40,000. Noted analyst Luke Groman reportedly reduced his Bitcoin holdings at $95,000 due to concerns including quantum computing risks, Bitcoin's comparative underperformance against gold, significant selling pressure from large holders ('whales'), a recent breakdown in chart patterns, and the perceived unfolding of a four-year market cycle. Groman is quoted as considering a re-entry point for bullish positioning at the $40,000 level. The current market is assessed as having been in a bullish trend prior to the anticipated December 19th event, with the predicted market trend being bearish. The analysis prompts consideration of whether this event will trigger a sharp depreciation or represent a final market 'shakeout' preceding a substantial upward movement.
