The quantum computing threat to Bitcoin has been largely debated by top market experts. Most see this technology, which could one day crack Bitcoin’s cryptography, as the end of crypto.
Clark Alexander, the co-founder and head of AI at Argentum AI, however, suggests that this threat could come in later years, far longer than perceived. This is despite Microsoft making advancements in quantum computing with its Majorana 1 chip. Hence, quantum computing will not pose any threat to BTC in 2026.
Is the quantum computing threat to Bitcoin just a factoid?
Speaking to Cointelegraph, Clark Alexander said that he expects quantum computing to have “extremely limited commercial use” in 2026, meaning it will not be breaking Bitcoin’s cryptography this coming year.
The co-founder of Coin Bureau and crypto analyst Nic Puckrin, however, was more blunt as he said the quantum computing threat to BTC is 90% marketing and 10% imminent. Puckrin claims that “we are almost certainly at least 10 years away from quantum computers that could break Bitcoin’s cryptography.”
Meanwhile, the SEC received a proposal in September warning that quantum computing could eventually break the encryption protecting Bitcoin and other digital assets.
