In an October 16, 2026 interview with William Joy, Justin Sun said advances in AI algorithms and quantum computing had made him more bearish on Bitcoin than before. He argued that the industry and investors holding Bitcoin through ETFs have not fully priced in those risks.
Sun also said progress in AI-driven mathematics could potentially let classical computers break existing cryptography, even before a quantum computing breakthrough. The claim puts cryptographic resilience, rather than near-term price action, at the center of his long-term Bitcoin thesis.

Why does Justin Sun think Bitcoin risks are underpriced?
Sun argued that the crypto industry and investors holding Bitcoin through ETFs have not fully priced in risks from AI advances and quantum computing.
-
How could AI affect Bitcoin's security according to Sun?
Sun said progress in AI-driven mathematics could potentially enable classical computers to break existing cryptography.
-
Could classical computers threaten Bitcoin before quantum computing advances?
According to Sun, AI progress could potentially create a cryptographic threat even before a quantum computing breakthrough.
-
Why are Bitcoin ETFs relevant to Sun's warning?
Bitcoin ETF investors are part of the market exposure Sun believes may not yet reflect the risks posed by AI and quantum computing.
-
Is Sun's concern focused on Bitcoin's price or its security?
The warning focuses on Bitcoin's cryptographic resilience and the possibility that technological advances could undermine existing cryptography.
