Currently, Ethereum is in a state of "short-term overbought + medium-term resistance level". When the Bollinger Bands contract or open downwards, prices often retrace along the band. The bearish strategy is essentially to "gamble on a phase correction", rather than a "trend reversal", so strict stop-losses and light positions for trial and error are necessary.

Ethereum suggestion: Short at 4170-4200, aiming for a wave correction to 4050-4000 $ETH #ETH突破4000
