The 15-minute Bollinger Bands for the big BTC coin are opening downward; the price is staying right along the middle band, and the short-term bearish trend is clear. The upper band at 66890-66900 is strong resistance, and the previous high at 66940 is a secondary resistance. The lower band at 66760-66770 is key support; if it breaks below, look for 66700.

Trading should mainly be focused on short positions. If there is a rebound near the upper band, you can take a small-sized short position to test, with targets at 66000-65500; don’t be stubborn about it. Pay close attention to whether the upper and lower bands break out, operate in line with the trend, strictly control position size, and respect market risk.
