Recently, the trend of Bitcoin resembles a sprite 'farmed' by the Bollinger Bands, bouncing up and down but having a stable bottom at 106000, with 104400 guarding the lower line, while 107500 has become the current most eye-catching 'pressure wall'. Watching the price rebound from the low to around 106700, it's now about to touch the upper band edge, we can aim to set up a short position near 107500! Why choose this? Because the upper band of the Bollinger Bands acts like the market's 'temper switch'—countless times in the past, when the price touches the upper band, it encounters resistance and falls back; this is the instinctive hesitation of funds at pressure points. Just like a basketball bounces back when it hits the backboard, Bitcoin is also likely to face a pullback when it meets the upper band. When Bitcoin approaches 107500, it might be worth daring to try a short position—taking advantage of the upper band’s resistance to bet on a pullback. #比特币
