According to Cas Abbé (@cas_abbe), the anticipated Altseason, where altcoins outperform Bitcoin, has not occurred since 2021 despite brief 2-3 week pumps followed by deeper corrections (source: Twitter, May 3, 2025). Abbé highlights that historical data shows true Altseason begins when Bitcoin dominance declines sharply—currently, BTC dominance remains high, indicating the conditions for a sustained Altcoin rally are not yet present. Traders are advised to monitor Bitcoin dominance charts and on-chain flows for early signals of Altseason, rather than reacting to short-term altcoin pumps (source: Twitter, May 3, 2025).
