September is already +9.07% — but the real historical setup is what comes next.

$BTC monthly seasonality shows:

• September average: -2.21%
• October average: +19.92%
• November average: +41.12%
• December average: +4.16%

If $BTC closes September strong, Q4 enters a historically favorable window.

Seasonality isn’t a signal — but it’s definitely a trend worth watching.
