Bitcoin and Ethereum have both surged high in the evening and have made profits as planned by going short. Now we need to watch if there will be a trend reversal. The key level for Bitcoin is 102000; it has managed to hold each time it dropped to this level over the past few days. If it doesn't break this level, it can still rise further. For Ethereum, we need to closely monitor 2430; it dipped to this level last night and then bounced back.

From the hourly and 4-hour charts, both have dropped to support levels and started to stabilize, with the trend still leaning towards bullish as long as they don't break their lows.

In terms of trading, Bitcoin can be bought near 102000-102500, with a target around 104000; for Ethereum, buying near 2460-2480, with a target near 2550.

However, if Bitcoin drops below 102000 or Ethereum falls below 2430, the market may turn bearish, so caution is needed for a potential trend reversal, and strategies should be adjusted in a timely manner.

Currently, the focus remains on low buys, with the key being whether the support levels can hold strong!
