In this episode of Bitcoin Brainstorm, Rod Roudi is joined by Cathie Wood, Adam Back, Hunter Beast, Rob Hamilton, Ren Crypto Fish, and David Puell for a deep discussion on quantum computing and its implications for Bitcoin. The group examines the technical, financial, and governance challenges posed by advances in quantum technology, while also exploring the progress being made on post-quantum cryptography and Bitcoin security research. From institutional concerns and custodial infrastructure to migration paths and consensus-building, the conversation highlights how developers, researchers, and investors are collaboratively addressing one of Bitcoin’s most discussed long-term risks.
