According to Compounding Quality on Twitter, two of the most common trading mistakes investors make are panic selling during bear markets and panic buying during bull markets (source: @QCompounding, May 10, 2025). These impulsive actions can lead to missed opportunities for gains and increase the risk of losses, especially in volatile markets such as cryptocurrency. Traders are advised to establish clear entry and exit strategies and to avoid emotional decisions that drive poor timing, which can significantly impact crypto portfolio performance.
