At the four-hour level, BTC's technical outlook has completely deteriorated. The moving average system is in a bearish alignment, with the price firmly suppressed below the MA5 (66,800 USD). Every volume-less rebound is just a trap to lure buyers, unable to form an effective reversal.

The MACD remains in a death cross below the zero line. Although the bearish momentum has slightly weakened, there are no signs of a golden cross or bottom divergence. This indicates that the decline is merely a "mid-term rest," not a "bottoming rebound."

The key point is that trading volume has plummeted, and market activity is very quiet. This extreme volume contraction often signals the calm before the storm, suggesting the market is waiting for a direction to be chosen. Combined with the current technical suppression, the probability of a subsequent downward break (below 65,600 USD) is much higher than the chance of an upward reversal.
