Weekend trading is relatively light, and Bitcoin has encountered some resistance at the 106200 USD level on the four-hour chart. The upper level of 107000 USD is even more significant, as it marks a breakdown point for Bitcoin on the four-hour chart, with substantial selling pressure.

The upper range of 108400 USD to 109000 USD represents strong resistance on the four-hour chart. Personally, I am not optimistic that Bitcoin can strongly break through and stabilize at the 109000 USD level in the short term.

From a daily chart perspective, the rebound of Bitcoin is not particularly strong, with the 109000 USD level firmly suppressed. In terms of trading, when reaching the 108000 USD to 109000 USD range, one can consider positioning for short positions, ensuring proper capital allocation and managing position sizes, and definitely avoiding heavy trading.

Ethereum is also experiencing a weak rebound. From the four-hour chart, Ethereum is restricted in the short term by the 2580 USD level, and the strong resistance on the upper four-hour chart is between 2650 USD and 2680 USD.

On the downside, closely monitor the strong support at the 2450 USD level on the four-hour chart to see if it will be forcefully breached.

From a daily chart perspective, Ethereum's weak rebound indicates a further weakening trend. The pressure on Ethereum from the daily chart is considerable, and without a significant bullish candle appearing on the daily chart to strongly break and stabilize at the 2780 USD level, Ethereum will have no chance of challenging the strong resistance at the 2850 USD bull-bear dividing line.

On the downside, closely watch the strong support at the 2450 USD level for Ethereum. If this level is forcefully breached on the daily chart, Ethereum will likely test the strong support at the 2300 USD level. This level is the watershed for Ethereum's bulls and bears, so everyone should pay close attention.
