Bitcoin continued its previous consolidation pattern in yesterday's early trading session, with a slight rally to 73,900 in the afternoon before facing resistance and pulling back. During the US trading hours, stimulated by macroeconomic positive news, it sharply dropped to a low of 72,450, then quickly rebounded to around 74,200, but the bulls failed to maintain the gains. In the early morning, it declined again, and the current price is fluctuating around 73,300. From a technical perspective, the 4-hour chart shows a converging structure of "bottoming out and rebounding + sharp rise and fall," with 72,450 and 74,200 forming a short-term range boundary; the Bollinger Bands are gradually narrowing, with the middle band pressing down near 73,800. The MACD fast and slow lines are converging below the zero line, with weak momentum bars, indicating a typical weak consolidation state. Liquidity is relatively thin over the weekend, and the market is expected to continue oscillating within the 73,000-74,000 range. In terms of trading strategy, it is advisable to buy low and sell high within the 72,450-74,200 range, and follow the trend if the range is broken, while strictly controlling positions to prevent whipsaws.
