When prices and assets go down, then emotions arise by themselves, and I made a sale and then bought it again below the price I sold before and automatically gets more coins than before. Then the coin price drops again, panic makes me stressed and emotional, finally I sold my assets at a cheap price again. That is why the feeling of emotion must be abandoned, because we will suffer losses. This includes my worst experience.
Emotions is a great factor that contribute to stress on every person. If a person's emotion is strong enough to affect him, theres a greater chance of panicking because the person may think negatively and may make an unwise decision without even thinking of its effect. He might lose some of what he has because of it.
