$BTC 4 hours level long and short confrontation continues to be fierce, prices are temporarily stable above the lower Bollinger Band, and the rising trend line around 111000 provides key support. The core operation revolves around the dividing point: if the 111000 trend line is not broken, we still insist on being bullish during the pullback; if the trend line unexpectedly breaks, although it will trigger a space pullback, the expectation for bulls to push higher again after the pullback ends remains unchanged.
