The cryptocurrency market is experiencing a wide range of fluctuations, leading to a tug-of-war between bulls and bears, with short-term bullish signals emerging.

On December 14, 2025, the cryptocurrency market underwent severe volatility, with Ethereum briefly dipping to a low of 3023, while Bitcoin plummeted to the critical support level of 87519, before both began to rebound. After the market sentiment experienced a rollercoaster ride, the subsequent market trend is gradually becoming clearer when combined with multi-period candlestick signals.

From the weekly candlestick perspective, the previously anticipated reversal pattern of a rising doji has been broken. Bitcoin has continued to decline after a brief reversal, closing with a red candlestick, presenting an overall bearish pattern. In contrast, Ethereum has shown relatively strong performance, closing green on the weekly chart and maintaining an upward trend, preserving the potential for a rebound in the market, which is expected to lead to a wave of upward movement in the short term.

On the monthly candlestick level, the signals for a switch between bulls and bears are evident. Ethereum's monthly chart has already turned green, while Bitcoin is facing a critical juncture of turning from red to green. If this month completes the transition of "green to red and then back to green," the upper target could aim for the 90000 integer level, with medium to long-term trends still holding potential.

The short-term trend focuses on the four-hour chart, where Bitcoin is currently in the lower Bollinger Band area, facing resistance at the 89000 level. Notably, the low of 87519 on the 14th has formed dual support near the previous low of 87000, showing no signs of further decline, and subsequently starting a rebound, reinforcing the short-term bullish logic. However, the bearish trend has not fundamentally changed, and it is recommended to primarily take short positions, waiting to see if the market can effectively break through the 89000 resistance level. If it breaks through, it could aim for around 90000; if it encounters resistance, caution should be exercised for the risk of another pullback.

The four-hour chart for Ethereum shows that the 3100 level has become a core resistance point, with the price consistently failing to break through the middle Bollinger Band, oscillating around this pressure point. It is also suitable to adopt a short-term bullish strategy; if the market continues to approach 3100, one could consider taking a short position to capitalize on the range fluctuations.

The short-term guidance from the one-hour chart should not be overlooked. If Bitcoin cannot break through the middle Bollinger Band, it may fall into a correction again, with a take-profit target temporarily set at 82900, or wait for a breakthrough at the 89000 level to observe the pressure situation of the middle band. If the pressure is relieved, a rebound above the high point of the 14th is expected; Ethereum's one-hour chart has shown a reversal signal, with the 3090-3091 range becoming a key resistance. If it cannot break through, a bearish outlook should be adopted.

In summary, based on the analysis of multiple technical periods, the operational strategy can be clearly defined: take direct long positions in the short term, targeting 89000 or 91000; from a long-term perspective, the 91000 resistance level has been confirmed as strong resistance through the weekly chart, making it temporarily difficult to break through, and one could consider positioning for short positions.

After the wide fluctuations in the market, the tug-of-war between bulls and bears has entered a critical stage, and future attention should be focused on the breakthrough of core points such as 89000 (Bitcoin) and 3100 (Ethereum). More market dynamics and strategy adjustments will be continuously updated tomorrow.
