ETH daily level, broke below the Bollinger Band middle line at $4,100, key support at $4,000 (psychological level + EMA30). Daily MACD has formed a death cross, RSI is oversold, short-term rebound is possible but lacks momentum.

In the short term, it will test the $4,000 support, and if it breaks, it will accelerate to $3,900 or even $3,750. A rebound needs to reclaim $4,250 to temporarily halt the downtrend.
