According to Miles Deutscher, the Altseason Index, which measures the breadth of altcoin performance, has closed below 50 and remains red due to recent poor performance of altcoins. This index needs to stay above 50 for three straight weeks to indicate a strong altseason, but current data shows zero score for market breadth, signaling continued weakness in the altcoin market and suggesting traders should exercise caution and adjust their crypto portfolio allocations accordingly (Source: Miles Deutscher on Twitter, June 9, 2025).

According to Miles Deutscher, the crypto market breadth indicator, which measures the percentage of altcoins on Binance above their 50-day moving average, has dropped to cycle lows, reaching as low as 3%. This indicates a challenging environment for traders to find outperforming altcoins.
