Ethereum has surged 20% to $3,339, marking its highest level in five months, as the cryptocurrency market enters an altcoin season. This rally is spurring gains in other altcoins, with Solana and XRP each rising by 5%. Analysts attribute the shift in capital from Bitcoin to top Layer-1 altcoins as a key driver of this trend. The market is further supported by upcoming U.S. legislation, with Congress poised to pass significant bills impacting the crypto sector. Bitcoin remains bullish, with forecasts suggesting prices could reach between $135,000 and $200,000 by 2025, fueled by institutional investments and favorable regulatory developments. The Altcoin Season Index reflects sustained momentum, with Ethereum's performance indicating potential for continued altcoin growth.
