According to ME News, on August 2 (UTC+8), David McAlvany, CEO of the gold investment app Vaulted, stated that he believes Bitcoin could disappear within the next four years due to quantum computing. He said that once quantum computers are able to rapidly solve the mathematical problems protecting Bitcoin private keys, “that would be the end of Bitcoin.” However, McAlvany later acknowledged that he cannot determine whether such a breakthrough will occur in four years, five years, or even two months. As of mid-2026, no quantum computer exists capable of breaking Bitcoin’s cryptographic algorithms. His viewpoint is based primarily on concerns about the future pace of quantum computing development, not on any actual security incidents. Galaxy Digital estimates that approximately 7 million BTC held in addresses have had their public keys exposed on-chain, valued at around $470 billion; Glassnode estimates 6.04 million BTC, representing 30.2% of Bitcoin’s total supply. Public key exposure does not equate to asset theft—these addresses are only at risk of actual theft if quantum computers can derive the corresponding private keys from the public keys. McAlvany also compared Bitcoin to gold and questioned whether Bitcoin could endure for 5,000 years. He expressed relative confidence that gold would still exist by then, but said Bitcoin “may or may not” still exist. Bitcoin developers currently hold differing views on potential solutions. BIP-360 proposes introducing quantum-resistant address types; BIP-361 plans to phase out support for legacy signatures over time, potentially permanently freezing assets of users who fail to migrate—including those believed to belong to Satoshi Nakamoto. Supporters argue that freezing assets is preferable to allowing quantum attackers to steal and dump them; critics view it as confiscation. Companies such as BOLTS Technologies and American Fortress are also developing cross-chain quantum-resistant solutions. American Fortress completed an $8 million seed round in May and claims its technology can protect assets without requiring users to migrate addresses; however, its technical whitepaper has not been published, and its design has not undergone public audit.

Summary
Bitcoin breaking news: Vaulted CEO David McAlvany warned that quantum computing could render Bitcoin obsolete within four years by breaking its encryption. While no quantum computer can currently crack Bitcoin’s algorithm, rapid advancements have raised alarms. Galaxy Digital and Glassnode estimate up to 700,000 BTC (valued at $470 billion) could be at risk if quantum attacks become feasible. Bitcoin news reveals that developers are divided on solutions, with BIP-360 and BIP-361 proposed as potential fixes. BOLTS Technologies and American Fortress are developing cross-chain, quantum-resistant tools.
