According to @rovercrc, Bitcoin repeated its typical September weakness and may see a Q4 rebound often referred to as Uptober. Source: @rovercrc on X, Sep 27, 2025. Historical data supports the seasonality claim: BTC’s September has frequently been negative while October-December have tended to deliver stronger returns across many years.

Traders commonly validate seasonality with derivatives metrics such as BTC options put-call skew and futures basis to gauge directional positioning and risk.
