The Altcoin Season Index (ASI) has slipped to 57, indicating a possible shift in the cryptocurrency market. The ASI, calculated by CoinMarketCap, measures the relative performance of top 100 altcoins against Bitcoin over the past 90 days. An ASI above 75 suggests an altcoin season, while below 25 indicates a Bitcoin season. The current ASI reading of 57 suggests a balanced market, with altcoins and Bitcoin experiencing comparable price fluctuations. It's worth noting that this is a dynamic indicator that can fluctuate rapidly, and investors should monitor its movements in conjunction with other market signals.
