Bitcoin's intraday rebound continues, with the trend maintaining a range-bound upward movement. In the morning, the price surged to around 87,500 but failed to stabilize and break through, subsequently entering a correction. It is currently trading around 84,000, gradually erasing previous gains. The short-hour chart shows that the price is operating near the middle axis of the four-hour Bollinger Bands, indicating a test of the middle axis support trend. The 4-hour MACD shows signs of a death cross, and the KDJ three lines are all pointing downwards. Today, the key focus is on the 84,000 level for a long-short battle; if it stabilizes, the price may rise again; if it fails to stabilize, the price may head towards the 81,000 mark. The overall trend is still around range-bound fluctuations, but the range has shifted upward. It is recommended to primarily take short positions, with some long positions as a supplement.

Long positions can be taken at 84,500-84,700, targeting around 82,500.

Ethereum can be shorted at 1,990-2,020, targeting around 1,900.
