$BTC On the 4-hour chart, the market clearly turns bearish. The price at 77,602 has already broken below the middle band of the Bollinger Bands at 77,398, and is moving toward the lower band area, indicating a weak trajectory.

The small support levels in the morning didn't hold at all, representing a stepwise breakdown, making the rebound very difficult.
Currently, there is a previous low at 76,504 that barely provides some support; if the bears continue to gain momentum, it is highly likely to probe deeper areas.
In summary, the 4-hour structure has broken down, and until a strong reversal occurs, it will be difficult to regain momentum.
