The Pectra upgrade on Ethereum has led to its market - leading performance, but the sustainability of long - term price support depends on various factors. Continuous development of the Ethereum ecosystem, adoption by new projects, and improvements in scalability are positive for sustained price support. However, potential challenges like competition from other blockchains, regulatory issues, or failure to implement future upgrades smoothly could weaken this support. If new blockchains offer more efficient or cost - effective solutions, developers and users may migrate, reducing Ethereum's demand and price - supporting ability.
