The performance chart of the last 90 days in the cryptocurrency market is presented to investors like a colorful heat map. The three-month outlook for the top 100 cryptocurrencies shows sharp divergences on the altcoin front. According to the latest data, altcoins continue to outperform Bitcoin over the past 90 days. The index currently sits at 32/100, suggesting the market remains firmly in Bitcoin Season mode. Only 32 of the top 100 cryptocurrencies have outperformed BTC over the past 90 days. The chart reveals weak momentum across the broader altcoin spectrum, with only a limited number of assets outperforming Bitcoin. The index was at 30 yesterday, 29 last week, and 51 last month. The gradual weakening of altcoins, particularly after last month's near-balanced performance, is noteworthy. The yearly peak of 87 (December 4, 2024) has been significantly removed. The yearly low was recorded between April 12 and 26, 2025. Related News: Altcoin Listed on Major Exchanges Announces Transaction Fee and Burn Notice What is the Status of Bitcoin Dominance?
