The expansion of Ethereum's Layer 2 (L2) ecosystem could impact the main chain's coin price in various ways. L2 solutions, like rollups, aim to boost scalability and lower transaction costs, potentially increasing Ethereum's overall utility and adoption. This could drive demand for ETH, as it's still needed for gas fees and staking, possibly supporting or raising the main chain price. However, if L2s siphon significant activity from the main chain, reducing its congestion and fee revenue for validators, it might pressure ETH's price downward. Market perception also plays a role—successful L2 growth could signal a stronger Ethereum network, boosting confidence, or dilute focus on the main chain. The net effect depends on adoption, L2-main chain interplay, and broader crypto trends.
