The 2025 Altcoin Season: Timing the Market and Positioning for Growth

The cryptocurrency market is at a pivotal inflection point in 2025. After years of Bitcoin and Ethereum dominating headlines, the stage is set for a broader altcoin rally. This article dissects the timing signals and fundamental catalysts driving the potential 2025 altcoin season, while identifying undervalued projects poised to outperform.

Market Cycle Analysis: When Will Altcoin Season Begin?

Historical altcoin seasons typically emerge when Bitcoin's market dominance (BTC.D) declines, signaling capital rotation into altcoins. Today, BTC.D has dropped to 62%, a level historically associated with altcoin outperformanceTop Undervalued Altcoins Poised for Growth in 2025^[1].
