Satoshi-era Bitcoin wakes after 16 years of dormancy as 600 BTC moves

Addresses dated to 2009–2010 moved roughly 600 BTC after about 16 years of dormancy, with on-chain trackers showing transfers into newer addresses and apparent consolidation. The activity triggered speculation because the coins originate from the Satoshi-era mining window, but there is no on-chain proof linking the keys to Nakamoto himself. From a market perspective 600 BTC is small relative to total supply and unlikely to materially affect price, though the event raises narrative and psychological risk that early-era holdings can re-enter circulation. It also underscores the importance of continued on-chain monitoring of century-old coins for custody and provenance signals.
