A significant Bitcoin wallet, inactive for eight years, has suddenly become active, transferring a substantial amount of cryptocurrency. This wallet accumulated its holdings in 2016 when Bitcoin's value was considerably lower, resulting in a massive increase in worth. Blockchain analytics firm Arkham Intelligence tracked these movements from what they have labelled a "250M BTC Whale". Such reactivations of long-dormant wallets are infrequent and underscore the substantial profits made by early Bitcoin adopters. The timing coincides with Bitcoin trading at a significantly higher value, though the reasons behind the wallet's activity remain unspecified.
