Last night's market was relatively calm. Bitcoin initially dropped to a low of 88,465, then eased up, rallying to around 89,908, only to be suppressed and fall back. Ethereum's pace was quite synchronized, rebounding from a low of 2,904 to 2,971, but then losing momentum and entering a range of oscillation.

From the candlestick chart, after several consecutive downward candles on the daily chart, there was finally a rebound. However, the rebound was limited; as soon as it rose, it was hammered down again. The MACD histogram has been mostly below the zero line, and the two lines are crossing downward, clearly indicating a bearish dominance. Looking at the four-hour chart, the price is oscillating below the middle band of the Bollinger Bands. Although it approached the middle band a few times, each time selling pressure pushed it back. The KDJ lines are also starting to turn downward. In this kind of trend, shorting during rebounds is the right approach.

Specifically: Bitcoin around 90,000 can consider shorting, with a target of 88,000; Ethereum in the 2970-3000 range is more prudent to short, with a target of 2850.
