A Bitcoin address dormant for 16 years has transferred 100.02 BTC, valued at approximately $8.55 million, according to Galaxy Research monitoring. The movement originates from the Satoshi era, marking one of the oldest known wallets to become active in recent memory. Bankless founder David Hoffman suggested the transfer may be intended to prepare for quantum-resistant attacks. This speculation highlights growing industry discussions around upgrading legacy holdings to protect against future cryptographic threats.
