Quantum Computing Poses Existential Threat to Bitcoin, Warns Hedge Fund CEO

A stark warning has been issued by Charles Edwards, founder and CEO of Capriole Investments, regarding Bitcoin's vulnerability to quantum computing. Edwards asserts that Bitcoin must rapidly transition to post-quantum signatures by 2026 to avert an "existential risk," dramatically accelerating the widely discussed timeline for such a monumental upgrade.

The Imminent Quantum Attack

Edwards' thesis centers on the potential for Shor's algorithm, run on advanced quantum computers, to compromise Bitcoin's elliptic-curve digital signature algorithm (ECDSA/Schnorr on secp256k1). Challenging the notion that quantum threats are decades away, he suggests that a quantum computer with approximately 2,000 logical qubits could break ECC-256 within a practical timeframe, potentially within "2-6 years." This forecast puts the cryptocurrency on a collision course with a "Q-Day" between 2027 and 2033, significantly sooner than more conservative estimates, such as those from NIST/PQ, which often project a broader IT system migration by 2035.

Vulnerability of Bitcoin's Digital Signatures

The core vulnerability arises when a Bitcoin address reveals its public key, typically upon spending or through legacy formats. Once exposed, a sufficiently powerful quantum computer running Shor's algorithm could theoretically derive the private key, enabling malicious actors to steal funds. This risk is particularly acute for coins associated with early "pay-to-pubkey" addresses, including those of Bitcoin's enigmatic creator, Satoshi Nakamoto. Edwards warns that without timely migration, "Satoshi’s coins will be market dumped." He is slated to elaborate on this "DOUBLE THREAT: Quantum & the Treasury Bubble" at the TOKEN2049 conference, positioning quantum compromise and a potential "Bitcoin Treasury Bubble" as the two dominant downside risks for BTC in the next market cycle. Bitcoin currently trades at $112,150 amidst these unfolding technological debates.
