The Ethereum 2.0 upgrade, transitioning from Proof of Work to Proof of Stake, significantly impacts ETH price and staking rewards. Progress, marked by milestones like the Beacon Chain (2020) and the Merge (2022), enhances scalability and energy efficiency, potentially boosting ETH demand. As more ETH is staked—currently over 30% of supply—circulating supply decreases, which could drive prices up if demand persists. However, post-Shanghai upgrade (2023), staking withdrawals might increase selling pressure, tempering gains. Staking rewards, initially estimated at 10-15%, have settled around 3-4% annually due to higher participation, reducing individual yields but stabilizing the network. While short-term price volatility may occur, long-term value could rise with improved utility and adoption, contingent on market sentiment and macroeconomic factors.
