A long-dormant Bitcoin (BTC) wallet has moved a massive sum after remaining inactive for eight years, according to Arkham.
Data from the blockchain analytics platform shows that the whale address received 5,908 BTC when prices hovered near $16,000 in 2017.
At the time, the Bitcoin stack was worth $99.63 million.
The whale held on to the massive Bitcoin stack even after BTC dropped to around $3,000 in 2018 and even after the largest digital asset by market cap soared to a cycle high of about $69,000 in 2021. The entity still kept the BTC wallet inactive despite Bitcoin’s drop to $15,500 in November of 2022, which briefly placed the position underwater.
The wallet remained inactive after Bitcoin surged to an all-time high of $126,000 in October of 2025. But on Thursday, the whale abruptly moved the massive BTC trove, now valued at roughly $383 million, into a fresh address.
No immediate sale appears to have occurred as the transfer went to an unmarked wallet rather than an exchange.
The move to a newer address format suggests possible custody updates or preparation for private transactions.
Such movements by large holders often signal strategic shifts without triggering immediate selling pressure on public markets.
At time of writing, Bitcoin is trading at $63,800, down more than 1% in the last 24 hours.
