A series of dormant Bitcoin wallets have reactivated, transferring a total of 645.49 BTC on September 11, 2025. Notably, a wallet from 2012 moved 232.16 BTC, with additional transactions from wallets dating back to 2012, 2013, 2014, 2015, and 2017. These movements involved splitting coins into Pay-to-Script-Hash (P2SH) wallets, potentially as a precaution against quantum computing threats. This activity highlights a significant reawakening of long-inactive Bitcoin holdings.
