Ethereum experienced a historic surge in the third quarter of 2025, with its value rising nearly 80% and reaching new all-time highs. This significant growth was fueled primarily by institutional investment in exchange-traded funds (ETFs) and key protocol updates. Ethereum surpassed $4,900, outpacing Bitcoin, and attracted increased attention from both DeFi enthusiasts and investors seeking to capitalize on the altcoin market’s surge. Notably, companies like BlackRock and Fidelity played a crucial role in driving this increase with significant ETF inflows. The development activity on the Ethereum network, as indicated by GitHub, shows continued innovation and advancement within the ecosystem.
