Uniswap V4's launch might initially boost UNI prices due to excitement and increased trading activity. New features like concentrated liquidity and enhanced composability could attract more users and liquidity providers. However, market reactions can be unpredictable. If users find the new features highly beneficial and user-friendly, it could drive sustained demand. But if there are technical glitches or if users struggle to adapt, prices might stabilize or even drop. Overall, positive feedback on usability and efficiency will likely correlate with higher UNI prices.
