SOURCE EVIDENCE

"For Bitcoin, quantum computing poses a theoretical risk: private keys could be derived from exposed public keys in 9 minutes, opening a pathway for unauthorized access to funds."

"Highly sophisticated adversaries can scrape the public blockchain today to collect exposed public keys ahead of the upcoming 'Q-Day.' According to some estimates, roughly 6.9 million BTC currently sits in legacy wallets or reused addresses where the public key has already been exposed on-chain."
