Core Viewpoint - Michael Saylor believes that quantum computing will enhance Bitcoin's resilience rather than weaken it, suggesting that the network will undergo a quantum resistance upgrade [1][2]. Group 1: Quantum Computing and Bitcoin - Saylor argues that quantum computing will not break Bitcoin but will instead "harden" it, leading to increased security and a decrease in supply, which will ultimately strengthen Bitcoin [2]. - Bitcoin security expert Jameson Lopp supports the idea of freezing unclaimed BTC after a quantum upgrade, noting that approximately 4 million BTC, or nearly 25% of the total supply, have had their public addresses exposed [3]. Group 2: Industry Perspectives - Grayscale's report indicates that quantum computing is unlikely to significantly impact cryptocurrency valuations in the short term, despite potential long-term risks to blockchain cryptography [5]. - Saylor has previously downplayed the quantum threat, asserting that major companies would not sell quantum computers capable of breaking cryptography, as it would jeopardize their own business [4]. Group 3: Market Activity - As of the latest data, Bitcoin (BTC) is trading at $86,845.44, reflecting a 0.41% increase in the last 24 hours, while Strategy Inc. shares experienced a slight decline in after-hours trading [6].

Grayscale said in its latest "2026 Digital Asset Outlook" that while quantum computing poses a long-term risk to blockchain cryptography, it is unlikely to affect Bitcoin—or the broader crypto market’s prices and valuations—in 2026. The report noted that most public blockchains will ultimately need to adopt post-quantum cryptography upgrades. However, a "cryptographically relevant" quantum computer capable of breaking Bitcoin’s public-key cryptography and forging digital signatures to steal assets is widely ...
