Bitcoin's seasonal pattern points to a strong finish to the year, which is good news for buyers willing to step in during a weak September.

• Buying the September low and holding to year-end has paid a median gain of more than 33% across past years.
• That trade worked nine out of fifteen times, and every losing year was a bear market year.
• The view here is that the current bear market is already over, which would put this year in the winning group.
• October is the single best month of the year by median return, up nearly 13%, and green ten of the last fourteen years.
• Even after a red September, October still finished higher six out of nine times.

Outlook: A weak September is treated as a buying window ahead of an expected strong October-to-December run.
