The Cardano founder made the remark while addressing whether Midnight, a privacy-focused sidechain, suggests Cardano cannot handle the job on its own.
Charles Hoskinson said Bitcoin is "the dumbest and least capable cryptocurrency" while responding to a question about whether Midnight implies Cardano is insufficient for certain use cases. The comment links to a broader debate over blockchain design trade-offs, including whether simpler networks like Bitcoin prioritize security and decentralization over programmability and broader functionality. Midnight is presented in the source as a separate initiative tied to Cardano-related development and framed around privacy-focused capabilities.
