January 4th midday, the trends of Bitcoin and Ethereum are worth paying close attention to. From a technical perspective, after the volume breakout above 91186, Bitcoin shows a different operational approach.

**Core Trend of Bitcoin**

Bitcoin has already broken through the hourly closing price level of 91186. For aggressive right-side traders, the current strategy is to recover stop-losses. Conversely, if Bitcoin drops below 90333 with volume, and cannot recover after a rebound, the opportunity for right-side shorting is to eat the pullback. At this point, closely observe whether the volume change matches, and protect your stop-loss accordingly.

In the case of a false breakdown at 89264, consider closing one long position. If the false breakdown low or subsequent drop below 88434 occurs, that is the stop-loss point. The key is: if it cannot recover, do not continue adding longs.

A breakout and stabilization at 91477 on the hourly level is a turning point. Once it stabilizes above 91477, there is momentum to look towards 92717-93575. If it stabilizes at this level and then takes off, the space ahead could be quite substantial. Short-sellers should watch for a second false breakout above 92717, where they can short one position, with a stop-loss set at 93575.

For conservative traders, consider going long at 88020, with a stop-loss at 87261.

**Importance of Trend Confirmation**

After Bitcoin broke out of the expanding megaphone pattern, the subsequent pullback confirmed the support at the upper boundary of the megaphone, providing a basis for further rise. Then it broke through the neckline at 90338, which also experienced a second pullback confirmation, making the support truly effective, and giving the momentum to reach 91567 later.

A good upward trend must experience a pullback after breaking resistance. This pullback confirmation is a sign of a healthy upward trend. If it rises directly without a pullback, it will eventually fall—this has been repeatedly validated in historical trends.

As long as Bitcoin does not fall below the support at 90338 during a pullback, it will not enter a correction mode. Assuming Bitcoin follows an AB=CD pattern, the highest target for point D is around 92365. But the premise is that Bitcoin needs to stabilize above the resistance at 91477 to look upward. If it cannot surpass 91477, it will likely oscillate between 91477 and 90338 in the short term, requiring observation while it moves.

**Summary of Resistance and Support Levels**

Resistance levels upward are 91477, 92717, 93575. Support levels downward are 90338, 89075, 88107. On the 4-hour level, if 90559 breaks downward, look towards 89286-88056.

**Ethereum's Approach**

Ethereum also broke through 3152 with volume; right-side traders need to recover stop-losses. If it drops below 3107 with volume, short positions should have stop-losses prepared.

If a pullback to 3038 confirms support, consider adding one long. Falling below 2994 is the stop-loss point.

After Ethereum stabilizes above 3152 on the hourly level, it can target 3185-3232. Watch the 3232 level above; a breakout above 3277 would set the stop-loss.

Another left-side order opportunity: go long at 2962, with a stop-loss if it drops below 2918.

Resistance levels above are 3152, 3185, 3232. Support levels below are 3103, 3075, 3019. If 3126 on the 4-hour level breaks downward, look towards 3074-3009 in the lower range.
