Bitcoin's current range-bound trading and decreasing market dominance could herald the onset of an altcoin season, according to recent analysis. Key indicators such as a rising TOTAL3 index and an Altcoin Season Index nearing 75 suggest a potential shift in market dynamics. Historically, a drop in Bitcoin's market share has led to increased capital flow into altcoins, particularly those with mid-to-small market capitalizations. Analysts advise traders to watch for Bitcoin consolidation, declining BTC dominance, and increasing altcoin volumes to strategically adjust their market exposure.
