Multiple signs suggest that an altcoin-led bull market is about to begin. Bitcoin's market dominance is hovering around 59.2%, which is a typical sign of funds shifting from Bitcoin to other cryptocurrencies. A similar situation occurred between 2019 and 2020, when changes in market dominance reignited retail investor interest and sent altcoin prices soaring. Market sentiment is shifting from fear to cautious optimism, and the weekend surge indicates that retail trading is back. If the Fed resumes quantitative easing in December, we could see a new wave of liquidity, and historically, such favorable conditions often drive investors toward higher-risk assets. Factors like market rotation, market psychology, and policy support all point to the possibility of an upcoming altcoin rally.
