Making decisions based on emotions is one of the most costly mistakes in trading. Acting out of fear of missing out or greed often leads to buying high and selling at a loss. Without a clear plan, many enter the market without setting goals, acceptable loss levels, or exit criteria, which can result in impulsive decisions and empty accounts. Additionally, blindly trusting what influencers or groups say without researching for oneself only exacerbates the problem. It is easy to get carried away by market euphoria or collective panic, but that rarely ends well. Conducting your own research and developing a solid strategy is key to protecting your capital. Discipline, risk management, and continuous learning are more valuable than any last-minute "tip." Successful trading is not a matter of luck, but of preparation, emotional control, and informed decisions.
