According to Cas Abbé on Twitter, the start of an altseason in 2025 requires three critical elements: surplus liquidity, retail investor participation, and a favorable macroeconomic environment. Surplus liquidity occurs when the Federal Reserve injects liquidity and cuts interest rates, which supports risk-on assets such as altcoins (source: Cas Abbé, Twitter, June 2, 2025). Traders should monitor Fed policy decisions closely as they directly impact crypto market sentiment and capital flows. Additionally, increased retail presence typically signals heightened speculative activity and potential for rapid altcoin gains, making these indicators essential for timing altcoin trades.
