Bitcoin Bollinger Band squeeze and chart breakout signal potential move toward $84,500

Bitcoin is trading near its all-time high after a strong rally from December 2023 to August 2025, with monthly Bollinger Bands now at their tightest levels and hinting at imminent volatility. A breakout above a symmetrical triangle pattern points to an upside target around $84,500, while onchain cost-basis clusters between $83,000 and $85,000 suggest strong resistance near $84,000 that could limit further gains.
