Bitcoin finishes the month around $77,661, up roughly 26.07%, its strongest August in years and a full reversal of the seasonal warnings that opened the month. The catch is what comes next: heatmap data circulating over the weekend points out that Bitcoin has not once posted a green September immediately following a green August in the period examined. It also remains about 38.4% below the October 2025 all-time high of $126,080, so the rally has recovered ground rather than broken new.
