Bitcoin broke out of a few days of narrow trading range yesterday, showing a downward breakout trend. Bitcoin lost the key support at $76,200, with a low of around $75,500. Previously, Bitcoin tested the $78,000-$78,500 range multiple times without success, indicating exhausted bullish momentum. Coupled with weak weekend liquidity, bears took the opportunity to push through the key support zone. Currently, attention should be paid to the $75,000 round number and the $74,500-$75,000 support zone below; resistance above has shifted down to $76,200-$76,500 (former support turned resistance). In terms of trading strategy, until the bearish structure is reversed, focus on shorting rebounds or observing. Bottom-fishing should wait for clear bottom stabilization signals (such as increased volume bullish candles or bullish divergence at the bottom).
