Altcoin Market Shows Bullish Supercycle Signs as Bitcoin Dominance Weakened

The altcoin market cap, excluding Bitcoin, surpassed a critical resistance point of $1.4 trillion in August 2025, breaking through after exhibiting a consistent double bottom trend on the monthly chart. This pattern echoes a similar structure to the 2018-2021 cycle, potentially signifying an upcoming wave of capital inflow into other cryptocurrencies. The market cap is currently sitting at $1.55 trillion and continues to grow, indicating a shift in investor preferences away from Bitcoin. This trend is further supported by the MACD indicator showing a positive crossover and green histogram bars, aligning with previous bullish momentum in the crypto space.
