In the current market, the four-hour chart of Bitcoin shows a stair-step upward trend, breaking through the upper Bollinger Band and with moving averages rising, indicating a short-term bullish momentum release. However, it is necessary to pay attention to the possibility of a pullback if it fails to stabilize above the upper band after the breakout. Although market sentiment has shifted from pessimism to optimism, caution is warranted regarding the profit-taking pressure that may arise from excessive optimism. The hourly chart, while displaying an upward intention with two bullish candles surrounding one bearish candle, also shows the upper Bollinger Band rising.
