Recently, the daily chart of Bitcoin has been quite interesting, with a pattern of alternating bullish and bearish candles, resembling a "plum blossom stake." This indicates that neither the bulls nor the bears have been able to decisively take control, and the market remains in a phase of consolidation and direction selection.

Switching to the 4-hour chart, some positive signs can be observed: the price has slightly increased compared to the weekend, and although the rise isn't significant, the latest candle closed bullish, indicating a short-term rebound possibility. The key indicator MACD's green bars are also shortening, suggesting that the downward momentum is weakening, and buying pressure is gradually increasing.

However, another indicator, KDJ, is stuck around 45, neither rising nor falling, clearly telling us: this is a consolidation phase, don't expect a big surge or plunge. Additionally, the current price and volume are somewhat "out of sync," which warrants caution.

Looking at the more detailed 1-hour chart, you'll notice that the support levels below are gradually rising, indicating that in the short term, the bullish strength is slightly stronger than the bearish.
