Cryptocurrency trading must rely on system principles, and must not rely on emotions and feelings. Otherwise, when the price rises, you will fall into fantasy, thinking that it will continue to rise, and thus be reluctant to reduce your position or sell; and when the price falls back, you will fantasize that the price will continue to fall or think that the market has ended, and dare not add positions at the callback point. Or because of short-term greed, short-term operations unknowingly become long-term swings, and eventually fall into chaos.
You must abandon emotionality and rely on system principles and discipline to restrain yourself. The purpose of the operation must be clear and definite, whether it is short-term, swings, or the proportion of adding and reducing positions must be strictly controlled. In this way, you can be like a fish in water and operate easily in the process of currency trading. On the contrary, those who are worried about gains and losses, greedy and regretful often end up with nothing.
