Fear is not a good/bad thing, it’s a human emotion, we cannot do away with it but we can try our best to control it. There is a type of fear that is common among the crypto community, it's called the fear of missing out (FOMO).  In my opinion, FOMO is one of the major factors why people lose money in the crypto markets, the fear of not making money when others are making it has driven many into making risky financial decisions without doing sufficient research.
