The SEC proposal is undoubtedly a good step for crypto market because people want clear rules which makes them more confident. Although i don't think this one news itself can start the next big bull run. Bitcoin and Ethereum can rise when demand for them increase, EFT buying, better economic conditions and institutional adoption will happen.
I consider this news as positive where clear and easy rules may encourage investment companies to use more crypto service and reduce the fear of unclear rules. Although several factors need to happen at the same time for such big event where this news plays position role but not the main reason for market
That’s why we yearn for bills such as the Clarity Act to be passed in the US, as Regulatory clarity can build confidence and make it easier for institutions to trust and enter the crypto market.
Though in itself, it isn’t enough to trigger a sustained bull market (as ETF inflows, actual demand, liquidity and broader economic conditions still matter), I'd still view this as a positive step that should support long-term adoption rather than the main catalyst for the next rally.
