As of May 6, 2025, the Altcoin Season Index—tracked by BlockchainCenter—has dropped to a value of just 24, reinforcing a strong shift toward Bitcoin dominance. Typically, a value below 25 signals a Bitcoin Season, while a reading above 75 marks an active Altcoin Season. With the current index sliding well below the neutral zone, altcoins appear to be losing momentum.
At the same time, Bitcoin’s dominance has surged to 65%, a level not seen since late 2020. This reflects a broader market trend where capital and attention are gravitating toward BTC, leaving altcoins struggling to reclaim investor interest.
Interpreting the Altcoin Season Index
The Altcoin Season Index is designed to measure whether altcoins are outperforming Bitcoin over a 90-day period. A low reading like today’s 24 means that very few top altcoins are beating BTC in returns, often signaling a market preference for risk-off, store-of-value assets like Bitcoin.

This metric is not just technical—it also serves as a sentiment indicator. When confidence in altcoins fades, capital typically rotates back into Bitcoin, often ahead of major macroeconomic events or after failed altcoin rallies.
Bitcoin Dominance Hits Multi-Year High
According to TradingView data, Bitcoin’s market dominance has steadily risen over the past few weeks, climbing from 60% in early April to the current 65%. This is a significant milestone, considering the index hovered near 50% for most of Q1 2025.

This rise in dominance signals a “flight to quality” mindset among investors. With rising global uncertainty and anticipation around the May 7 Fed meeting, traders appear to be rotating out of speculative altcoins and into what they perceive as safer crypto assets.
What This Means for Altcoins
The combination of a low Altcoin Season Index and rising Bitcoin dominance suggests:
- Capital is consolidating into Bitcoin, especially from institutional flows.
- Altcoin rallies are unlikely to gain traction unless BTC stabilizes or retraces.
- Retail interest in meme coins or high-risk tokens may cool if major altcoins continue underperforming.
In the short term, altcoin investors may need to manage expectations, especially for tokens without strong fundamentals or catalysts. That said, some view this as an accumulation phase for undervalued altcoins that could rebound later in the cycle.
Final Thoughts: A Pause Before the Next Rotation?
Markets move in cycles, and while this is clearly a “Bitcoin season,” it doesn’t mean altcoins are done for 2025. Historically, strong BTC dominance has often preceded a sharp altcoin rally once confidence returns and macro conditions ease. For now, however, the data speaks clearly: Bitcoin is leading the pack, and altcoins are taking a breather.
