According to @rovercrc, Bitcoin dominance (BTC.D) is on the verge of a monthly MACD bearish crossover, as indicated by his posted chart on Aug 15, 2025, which he frames as a potential shift in market leadership away from BTC if confirmed, source: @rovercrc. According to @rovercrc, he links similar monthly MACD bearish crosses in 2017 and 2021 to subsequent periods of strong altcoin outperformance, suggesting a rotation dynamic consistent with past altseasons, source: @rovercrc.
