According to @rovercrc, sharks are buying Bitcoin now, as posted on X on Sep 12, 2025, signaling perceived BTC accumulation by mid-sized investor cohorts at the time of the post (source: @rovercrc on X, Sep 12, 2025). The post provides no supporting on-chain metrics or wallet cohort definitions, so the assertion remains unverified within the post itself and requires independent confirmation before trading decisions (source: @rovercrc on X, Sep 12, 2025). For trade validation, market participants typically review on-chain cohort balance trends, exchange net flows, and spot-futures basis to confirm accumulation signals and assess positioning (source: Glassnode Academy; IntoTheBlock Learn; CME Group education).
