Originally used to describe a social networking phenomenon in the early 2000s, the saying "FOMO," or Fear of Missing Out, has become a common term in the world of cryptocurrency trading due to the market's high volatility. It's not unusual for cryptocurrencies to experience daily fluctuations of over 20%, causing impulsive decisions by investors and traders in pursuit of a trade. This behavior should be avoided at all costs. It's important to make trading decisions with a clear head and not worry about missed opportunities. There will always be another trade, so keep learning to prepare for the next one.
