Quantum computing has become a durable risk narrative for Bitcoin. This week, Galaxy Digital head of research Alex Thorn sat down with Strategy executive chairman Michael Saylor addressing the issue, shortly after Saylor posted his own “Bitcoin Quantum Leap” thesis on X. “The Bitcoin Quantum Leap: Quantum computing won’t break Bitcoin—it will harden it. The […]
Some computer scientists say quantum computers are moving closer to reality and will cripple bitcoin’s encryption systems and doom bitcoin. Governments are investing aggressively in quantum computers, which are ultra powerful. Quantum computers, first theorized by physicist Richard Feynman in 1982, have promised a new era of computing. The theory has only recently translated into significant real-world advances, with NASA, the CIA and Google working on a quantum computer. Computer scientists now warn the machines will cripple existing encryption methods and destroy bitcoin’s technological....
The development of quantum computers may spell the doom of Bitcoin. Bitcoin is dead! It has been predicted 112 times already. There is even a website that keeps track of all these obituaries. The latest prophecy predicts the death of Bitcoin once quantum computers make an entry. This plausible prediction comes at the time when Bitcoin is going strong, rebounding from a recent dip in its price following the BitFinex hacking incident. The threat of quantum computers on Bitcoin was predicted by Andersen Cheng, the co-founder of a UK-based cyber security firm, Post Quantum. He was quoted by a....
Quantum risk has become a recurring stress point in Bitcoin discourse, often framed as an existential threat. The claim usually follows a familiar arc: quantum computing is advancing quickly, cryptography is vulnerable, and Bitcoin isn’t adapting fast enough. Marty Bent doesn’t buy that framing. In his Dec. 14 episode, Bent acknowledged that quantum computing represents […]
Quantum risk has been getting louder in the Bitcoin conversation over the past few months. The question is whether that noise translates into price pressure in 2026. Grayscale’s answer, in its updated 2026 Digital Asset Outlook: “Dawn of the Institutional Era” (last updated Dec. 15), is essentially no. Quantum belongs on the risk register and […]
