Altcoins have maintained superior performance relative to Bitcoin for a record-breaking 31 consecutive days in 2025, marking the longest sustained period of altcoin dominance observed in cryptocurrency markets.
The unprecedented streak is primarily attributed to Ethereum’s significant price surge, which acted as a major catalyst, alongside sharply increased trading volumes across altcoin markets. South Korea emerged as a key demand driver, reporting trading volume spikes exceeding $4 billion during this period.
Geopolitical factors including heightened tensions between the U.S. and Russia have contributed to shifting market dynamics influencing the altcoin rally. Conversely, institutional investors including BlackRock and Harvard University’s Endowment continue demonstrating strong interest in Bitcoin through dedicated exchange-traded fund products.
