Bitcoin Bear Market May Be Entering Final Stretch in October

A chart analyst tracking Bitcoin's historical four-year cycle believes that it may be entering its final stretch of a bear market, possibly forming a bottom as soon as October.

The current downturn began after Bitcoin's October 2025 high and is following the typical pattern of one year of decline followed by three years of growth.

A rejection from the full $66,230 to $76,640 resistance zone could open a path down toward $56,500, then $44,000, with $39,000 identified as a further downside target if selling accelerates.
