No more guessing about the rise and fall, Bitcoin is charging straight to 81k with an unyielding pace. Will it rise further tonight? The signal on the chart is very clear, and you might not even know it! Regarding tonight's trend, no time for small talk, let's get straight to the point!

1. During the Asia-Europe trading session, Bitcoin maintained a high-level sideways fluctuation, with little change in the short-term trend; at this point, the divergence between bulls and bears is growing larger, whether you are in cash or fully invested, it's all a bit nerve-wracking!

2. After a significant surge, the chips in the market are becoming increasingly concentrated, which can easily lead to dramatic fluctuations in a short period; at this position, whether you are bullish or bearish, the technical indicators are already in a seriously overbought zone. Monthly traders should be careful to manage their pace, or else they might get hit from both sides!

3. Friends who have been following for a long time know that when it's time for the old nine to show a pattern, he does, and when it's time to be cautious, he does not hesitate! Now that the market trend has reached a cautious point, everyone should have a sense of it themselves!

4. Today is Monday, excluding the impact of sudden news, it is expected that Bitcoin will mainly experience short-term fluctuations and corrections tonight. Focus on support around 80.2k and 78.8k below, and resistance around 81.5k and 81.8k above. The overall strategy (light position) is to short at highs!
