The Ethereum 2.0 upgrade, transitioning from Proof of Work to Proof of Stake, has significantly impacted ETH’s price. Launched in phases starting December 2020, it aims to improve scalability, security, and energy efficiency. Initially, ETH prices surged due to optimism, reaching an all-time high of $4,891 in November 2021. The upgrade’s staking mechanism reduced supply as over 13 million ETH were locked by early 2025, driving scarcity and supporting price growth. However, delays and market volatility caused fluctuations—post-merge in September 2022, ETH dipped below $1,300 before recovering. Analysts predict that enhanced network utility and lower transaction costs could push ETH toward $5,000-$7,000 long-term, though macroeconomic factors and crypto sentiment remain key variables. As of March 4, 2025, ETH hovers around $3,800, reflecting cautious optimism. (134 words)
