Common mistakes in cryptocurrency trading include: blindly chasing highs and cutting losses, excessive leverage, not setting stop-losses, emotional trading, and lack of risk management and capital planning. Many beginners tend to trade frequently due to short-term fluctuations, leading to increased losses. Additionally, neglecting fundamental and technical analysis, over-relying on community information, and copy-pasting orders are also common. Successful trading requires discipline, strategy, and learning to avoid greed and panic-driven decisions, in order to remain undefeated in a highly volatile market.
