Major crypto exchange leadership just shifted stance on a critical market-structure bill—backing away from support. This kind of policy reversal matters. When top industry figures change positions on regulatory frameworks, it often signals concerns about implementation details or political feasibility. The crypto market structure debate has been heating up, with exchanges weighing in on how trading venues should be regulated. A CEO walking back support suggests either the bill's current form doesn't align with business interests, or broader industry consensus is moving elsewhere. Worth watching how this influences the legislative path forward and whether other players follow suit.
