According to Michaël van de Poppe, current market sentiment mirrors late 2018 and late 2020, periods notorious for significant declines in altcoin valuations. He notes that sentiment has reached its most negative in years, with many investors exiting the market. Historically, such negative sentiment has often preceded a major market run, suggesting potential opportunities for traders looking to capitalize on undervalued assets.
