According to Michaël van de Poppe (@CryptoMichNL), many crypto traders remain psychologically anchored in a bear market mindset and are not adequately prepared for the incoming altcoin bull run (source: Twitter, June 9, 2025). This sentiment highlights a potential opportunity for traders to reassess portfolio strategies and take advantage of undervalued altcoin assets as market sentiment shifts. Monitoring on-chain data, trading volumes, and social trends for altcoins can provide actionable insights for timely entries, especially as liquidity and volatility are expected to rise during this cycle.
