what is your opinion?
Buying and selling is only a small part of trading.
I guess it makes sense. The more you stare at the charts the more tempted you are to panic buy or panic sell. I have similar experiences. Don't feel like you are oalone, though. Even very experienced traders know that sometimes they will make mistakes because of emotions.
If you have this problem then i would actually suggest you spend more time on researching the coins you are trading, instead of actually buying and selling. The more you spend on buying and selling, the more fees you are going to incur, and the more likely you are going to let your emotions penetrate your logic.
