A recent analysis by Glassnode reveals that nearly 10% of the total Bitcoin supply is at risk due to vulnerabilities associated with quantum computing advancements. Specifically, 4.12 million Bitcoin, amounting to 20.6% of the total supply, are deemed 'operationally unsafe' because of issues related to key or address management. In contrast, 13.99 million Bitcoin (approximately 69.8%) remain unaffected by potential quantum threats. The report aligns with Ark Invest's findings that indicate a significant portion of Bitcoin is safe. Notably, major corporate entities such as Franklin Templeton, WisdomTree, and Robinhood have all of their Bitcoin holdings exposed to these risks. Furthermore, when analyzing cryptocurrency exchanges, only 5% of Bitcoin on Coinbase is at risk, while 85% of holdings on Binance are vulnerable. To mitigate these risks, Glassnode recommends that exchanges and custodians enhance their key management practices and transition to quantum-resistant formats in anticipation of future quantum breakthroughs.
