Bitcoin Price Stabilizes at $66,000-$67,000 Amid Quantum Threat Concerns

The price of Bitcoin (BTC) has been range-bound around $66,000-$67,000 in recent days, with some analysts warning that the market may be underestimating the threat posed by quantum computers.

Quantum computing uses quantum mechanical phenomena to process information exponentially faster than classical computers, and researchers are working on developing powerful quantum machines. Google's quantum milestones have reignited debate over Bitcoin's SHA-256 hashing and elliptic curve cryptography (ECDSA), which secure every wallet and transaction on the network.

An analysis of Google's quantum paper found that the crypto sector broadly underestimates the asymmetric risk posed by a sufficiently powerful quantum machine, which could potentially derive private keys from public addresses, rendering cold storage irrelevant. Bitcoin Core developers have acknowledged the long-term threat, with post-quantum cryptography upgrades discussed but no consensus timeline confirmed.
