As of today, Bitcoin is at a critical turning point. The technical indicators and institutional capital inflow support a bullish outlook, but caution is needed for potential volatility following the Federal Reserve's decision. It is recommended to adopt a strategy of 'follow the breakout + defensive on pullbacks,' with a reasonable position control (50%-70%) and retain 30% cash to respond to extreme market conditions. In the medium to long term, the deepening consensus of Bitcoin as 'digital gold' and the inflow of ETF funds remain the core drivers. After breaking the $100,000 mark, a new round of accelerated market activity may begin.
