I don't think only newbies make this mistake, but even seasoned market participants and professionals will find it difficult to control their emotions. It can be said that emotions are the most difficult thing to control, difficult to control it according to the plan that we have set. Whether our plans or strategies succeed is almost entirely determined by our emotions. For me, emotions are the most important thing in investing and trade because if left unchecked, it will lead to wrong actions.
Controlling emotions in trading is not as easy as it seems, even though they say it is. The failure of a trader to control their emotions will only make it difficult for them to make the best decisions when trading, it will also make them tend to lose because they are too hasty in making decisions.
It is true that traders should also be quite able to control their emotions when they realize that crypto trading is a very risky trade. The slightest mistake that is ignored will allow them to get a loss which they later regret. Emotional control is important, it is also included in the trading psychology chapter.
