Ethereum Analysis and Reference Strategy:

After the big bullish rise two days ago, yesterday a solid bearish candle directly pierced the market, closing from 3547 to 3300. A bearish engulfing signal appeared near the upper Bollinger Band on the daily chart, indicating that the overall short-term trend has undoubtedly shifted from a bullish trend to a bearish trend. It is expected that today will continue to decline, with intraday resistance at 3380 and 3460 suppressing the market rebound.

Looking at the short-term, the four-hour chart shows an M-top trend at high levels, with support at the bottom around 3250. The downward pressure in the short term still exists. Following the appearance of the M-top, even if there is a rebound afterward, it is highly likely that it will either be a spike or a failed rebound before continuing to decline.

In summary: short-term oversold rebound is expected, and a short-term support is likely to form near 3250 in the evening session. For today, a rise followed by a fall is anticipated, but bullish profits are not advisable. It is recommended to use a small defense to go short near the top resistance levels, which is safer, and there is still considerable space at the upper level's bottom. It is expected that this week or next week may drop to 3050-2850. Therefore, the suggestion is to focus on high positions today, reference points: 3380, 3460.
