This week, Bitcoin has shown a typical wide-ranging fluctuation pattern on the 4-hour level, with prices repeatedly testing key support and resistance areas, but failing to form a clear trend direction. This up-and-down movement is largely related to sudden news from the external market. The Trump administration's repeated statements on tariff policies, from increasing tariffs to delaying implementation, and then being questioned for insider trading, have led to increased volatility in global risk assets. The daily changing news has left market participants in temporary confusion, with both bulls and bears frequently battling at key price levels, resulting in a chaotic situation of rapid pumps and plunges in the market data.

Although the overall direction is unclear, the short-term trading window this week is exceptionally clear. The support and resistance strategy shared daily by Liang Hua has accurately captured swing opportunities within the range, such as repeatedly suggesting to buy the dip in the 74500-75000 area, and decisively advising to take profit or short above 83000. Long-time followers not only avoided the impact of unexpected negative news but also achieved stable profits during the fluctuations. The more chaotic the market, the more strictly discipline must be maintained. This week once again validated the importance of planned trading and trading plans.

From the current technical structure, Bitcoin has entered a critical decision period at the daily level. The 88000-90000 area above has gathered historical high selling pressure and the Fibonacci extension level at the weekly level, forming dual technical resistance. In the 4-hour chart, although the price has temporarily stabilized around 83000-84000, there has been significant selling pressure after multiple attempts to rally to 86000, indicating that bullish momentum is gradually weakening. Combining this with market sentiment observations, retail FOMO sentiment has warmed up as the price approaches previous highs, often indicating that a short-term top is near.

It is expected that at the beginning of next week, the market may attempt to rise again, testing the daily pressure level near 88000, possibly driven by lingering news sentiment. This process may be accompanied by rapid price surges, and even false breakouts to lure in buyers. However, caution is warranted; if the price cannot effectively hold above the 88000 level by midweek, a deep correction is highly likely, with the first target looking towards the 80000-78000 area. In terms of trading strategy, it is advisable to adopt a rhythm of going long first and then short: if there is a rebound to the 87500-88500 range at the beginning of the week, positions can gradually be built for short sales, with stop-loss set above 89500 and targets looking down towards 82000 and 80000 in batches. Short-term traders should still pay attention to the defensive situation of the 83000 support level; a break below it followed by a rebound could present an opportunity to increase positions.

Medium to long-term operation suggestions:
Sell Bitcoin around 88000, target focus on around 77000; sell Ethereum around 1730, target focus on around 1450.
