Bitcoin Doesn't Face 'Existential' Risk From Quantum Computers, Says Brian Armstrong: 'With Good Work, We Can Make Sure That Lands In A Good Place'

Brian Armstrong, the CEO of Coinbase Global Inc. (NASDAQ:COIN), brushed off quantum computing threats to Bitcoin (CRYPTO: BTC) and cryptocurrencies at large. Armstrong Says Quantum Risks Needs ‘Diligent Effort’ Armstrong posted on X, sharing a clip from his March 18 interview with Norges Bank Investment Management CEO Nicolai Tangen, where he stated quantum computing demands “diligent effort” but isn’t an “existential” risk to Bitcoin. “I think that with good work, we can make sure that lands in a good place, ” the cryptocurrency billionaire added.

So sometimes people are trading based on what they think other people are going to do, not what they think the reality is,” he argued. A Solvable Issue? Armstrong’s remarks echo what he said last month, describing quantum computing as a “very solvable” issue and that Coinbase is already "front-footed" in addressing it. Coinbase announced the formation of an advisory board earlier this year to assess the implications of quantum computing and prepare for "threats," even those many years away. The issue continues to ignite diverging views, with some experts suggesting that it could pose a significant threat to the industry’s future. Cryptocurrency analyst Willy Woo said that fixing quantum computing risks is the most critical step for Bitcoin's global adoption and its emergence as a major force in macro geopolitics. Renowned investor Kevin O'Leary also warned that fears over quantum computing could deter institutional investors from increasing exposure to Bitcoin. Jameson Lopp, Chief Security Officer at self-custody platform firm Casa, estimated a "greater than 50% chance" that it will take at least another decade before a quantum computer, powerful enough to decode a Bitcoin public key to find its corresponding private key, becomes a reality.
