I completely agree with you! Investing your last or borrowed money in trading is a direct path to stress and losses. When you trade with feelings of fear or greed, you make impulsive decisions, and this always leads to mistakes.
Trading is not a casino; here, calculation and a cool head are important. It is better to trade only with the money you are willing to lose and to perceive this as a long-term process, not a way to 'get rich quick'.
