Nearly 10% of Bitcoin Supply Vulnerable to Quantum Computing Threat

Glassnode reports nearly 10% of Bitcoin's supply (1.92 million BTC) is structurally unsafe from quantum computing, including early Satoshi-era coins and Taproot addresses. While 70% is safe, 20.6% is operationally unsafe due to key management issues. Major entities like Franklin Templeton and Binance show significant exposure.
