Bitcoin quantum threat faces hardware limits, leaving time to respond, Visser says

Hardware constraints on quantum computing leave time to address its potential threat to Bitcoin, according to macro investor Jordy Visser. He argued that the spread of AI-driven cyberattacks could also accelerate financial institutions’ adoption of cryptography and investment in security.

In an October 24 interview with Anthony Pompliano, Visser, a VisserLabs author and macro investor, rejected the claim that quantum computing would drive Bitcoin’s value to zero. He said physical constraints on the technology’s development meant there would be time to respond.

Visser cited cryptographer Adam Back as an influence on his assessment. He said Back estimated a timeline of 20 to 40 years for quantum computing to reach a threatening level, while others put it at five to seven years. Visser described quantum computing as “a hardware issue,” drawing a parallel with the physical bottlenecks limiting AI development and use.

He nevertheless agreed that the Bitcoin community needed to work together on a solution. Existing security problems in finance could hasten the shift toward systems based on cryptography, he argued, because crises accelerate responses. His comments emphasized the need to prepare and the time available, without setting out a specific technical remedy.

Visser identified password attacks by swarms of AI agents as a more immediate concern. Reusing passwords across websites creates vulnerabilities that become more significant as agents operate at scale, he said. He added that he had examined security risks and potential responses before making Bitcoin a significant part of his net worth in 2020.

Banks’ growing involvement in cryptocurrency infrastructure could provide another incentive to develop defenses, Visser said. As financial institutions enter that infrastructure, their interest in accelerating Bitcoin security solutions increases, he argued. While he viewed cryptography as stronger than existing security approaches, he said a solution to the quantum threat would still need to be developed within that framework.
