Gold Finance reports that Citigroup analysts stated in a report on Monday: 'Given that Ethereum is the only major cryptocurrency approved as a spot ETF base (aside from Bitcoin), it may be a rotation target.' Other cryptocurrencies have performed even better, and their share in the overall cryptocurrency market capitalization is also growing. Citigroup added that respondents to a recent survey believe that in 2025, altcoins will perform particularly well. Analysts stated: 'The performance of other cryptocurrencies and altcoins is even more meaningful, indicating that some market participants expect a 'altcoin season' in 2025 after a strong year for Bitcoin.' Experts indicate that the differing trends of Bitcoin and other cryptocurrencies stem from the fundamental factors affecting these two markets.
