The Ethereum 2.0 upgrade, transitioning from proof-of-work to proof-of-stake, aims to enhance scalability, security, and sustainability. This shift could significantly impact ETH price trends. By reducing issuance rates (e.g., post-Merge ~90% drop), it may create a supply shock, potentially driving prices upward, as some analysts predict ETH could hit $5,000-$20,000 by 2030. Market expectations are mixed: optimists highlight staking and lower fees boosting demand, while skeptics note high gas fees persist until sharding is fully implemented. Historical upgrades show short-term volatility but long-term growth potential. Layer 2 solutions and institutional adoption further fuel bullish sentiment. However, macroeconomic factors and competition from rivals like Cardano could temper gains. Overall, the market anticipates growth, though timing and scale remain uncertain.
