CoinShares: The quantum risk of BTC is controllable, and market concerns are exaggerated

CoinShares stated that the possibility of practical quantum computers emerging in the future is not zero, sparking intense debate about the potential impact on Bitcoin security. The quantum vulnerability of Bitcoin is not an imminent crisis but a foreseeable engineering problem, and there is ample time for adjustments.From a technical perspective, the so-called quantum risk mainly comes from Shor's algorithm potentially breaking ECDSA or Schnorr signatures, thereby exposing private keys; Grover's algorithm could theoretically weaken the security strength of SHA-256. The primary potential impact is on approximately 1.7 million BTC that were early adopters of P2PK addresses, accounting for about 8% of the total supply, so the likelihood of causing a systemic market shock in the short term is limited. The common market claim that "about 25% of the supply is at risk" is considered an obvious exaggeration, as a significant portion of the risk can be mitigated through address migration and other means.Long-term attacks may have theoretical feasibility within the next decade, but short-term attacks, such as cracking private keys within 10 minutes in the mempool, remain fundamentally unfeasible in the foreseeable future, even for decades. The scale of BTC that might enter the market due to private key leaks is roughly only about 10,000 BTC, and even if it occurs, the impact on the price system is limited.Holders can proactively migrate to more secure address structures. The remaining potential targets are dispersed across about 34,000 addresses, averaging about 50 BTC each, and even under extremely optimistic assumptions of quantum technological breakthroughs, completing a comprehensive attack could still take decades.
