According to @lookonchain, a dormant whale moved 1,000 BTC valued at about $116.88M to new wallets after 12 years of inactivity, with the sending address identified as 1NzHXRDizgEGaJZfBG46k66QXpRzDrtpZo on Arkham Intel explorer (source: Lookonchain on X, Sep 17, 2025; Arkham Intel). @lookonchain also reports the coins were originally received 12 years ago for roughly $847K when BTC traded near $847, implying an average cost basis of about $847 per BTC (source: Lookonchain on X, Sep 17, 2025). Based on those figures from @lookonchain, the implied unrealized gain versus the reported current value is approximately $116.03M, or around 138x, and no exchange deposits were cited in the alert, making subsequent transfers from the new wallets the key on-chain signal to watch (source: Lookonchain on X, Sep 17, 2025; Arkham Intel).
