Altseason refers to the period when altcoins perform strongly relative to Bitcoin. Typically, after Bitcoin rises or consolidates, funds start to flow into smaller market cap tokens. Currently, the market is still dominated by Bitcoin, but if Bitcoin stabilizes at a high level and funds flow back into altcoins, Altseason may begin. Investors should pay attention to fund flows, ETH/BTC trends, and signals of major altcoin movements to seize opportunities.
