Bitcoin's price movement today largely aligns with expectations—volatility has narrowed, and it has been oscillating within the 91,500-90,000 range. Ethereum is stuck in a narrow range between 3,130 and 3,100. The short-selling strategy provided this morning still offers opportunities for traders who follow it promptly.

Currently, the rebound is clearly weak. Bitcoin faces resistance at 91,600, and Ethereum is also stuck at the 3,150 level, unable to break through smoothly. From a technical chart perspective, this rebound is essentially a weak correction within a downtrend. On the 4-hour K-line, the Bollinger Bands have already turned downward. After the price broke below the lower band, a small bullish rebound appeared, but moving averages and various indicators remain weak, giving us repeated short-selling opportunities.

In the evening, attention should also be paid to non-farm payroll data, unemployment benefit data, and US tariff-related announcements, as these news events could cause market volatility. It is expected that the market will continue to oscillate within a narrow range before the news is released. Currently, the price remains above the middle Bollinger Band. If it further tests the resistance at the upper band around 91,500 and breaks through effectively, there could be room to move up toward 93,000. If the breakout fails, a downward correction is within expectations. The short-term strategy remains focused on high-level short positions, with key attention on the effectiveness of the upper band resistance.
