The syndrome of fear of being left out in a crowd, also known as FOMO (short for Fear of Missing Out), is a common psychological state in modern society, especially in the digital age and social media. Those suffering from this syndrome often feel anxious and restless when they see others experiencing something they are not a part of – whether it is an investment opportunity, a social event, or new trends.

In the field of cryptocurrency, FOMO often causes investors to rush into buying coins when they see prices rising, fearing they will miss a "life-changing opportunity," without thoroughly analyzing the project or the risks involved. This can easily lead to irrational decisions and the consequence of buying high and selling low.

Psychologically, FOMO stems from the fear of being left behind, the feeling of not being connected to the community, or the desire to be recognized. The more one compares oneself to others (especially through social media), the stronger this feeling becomes.

To overcome this syndrome, one needs to cultivate self-awareness, understand personal needs and goals, and learn to control emotions to avoid being swept up by the crowd. Knowing how to say "no," knowing when to wait for the right opportunity – that is true strength in a world that is always noisy and hurried.
