Dormant 4,000 BTC Miner Wallet Awakens Amid Potential Quantum Attack Fears
A 14-year-dormant Bitcoin miner wallet holding 4,000 BTC ($442M) recently moved 150 BTC amid concerns over quantum computing threats.Summary
An early Bitcoin miner wallet, inactive for 14 years and holding approximately 4,000 BTC (valued at $442 million), has become active, transferring 150 BTC ($16.6 million). The coins were originally mined in 2009 and consolidated in 2011. This movement aligns with a broader trend of early 'OG' holders selling after Bitcoin surpassed the $100,000 milestone, realizing significant profits. However, analysts also suggest the activity could be a preemptive security measure against potential quantum computing attacks. Nicholas Gregory, a Bitcoin OG, noted that older addresses, particularly P2PK or reused P2PKH addresses, might have exposed public keys vulnerable to quantum hacks, making the transfer a move to safer, unexposed addresses.
