People panic for one reason - when they don't know what to do. Imagine you have a disaster plan, will you panic? No.
Only if things don't go according to plan. Most people don't have any plans for crypto at all.
People panic for not knowing what to do because of lack of knowledge. If you're a kind of investor who fill your mind first with knowledge about what you're getting into then it can be prevented. However we are just human who commit mistakes, thus its normal but there's a way to not become someone who often panic if things didnt happen according to planned. It can help if we prepare ourselves for unexpected scenarios plus having plan and strategy, this way we know what to do and panicking wont be the solution.
I would argue that people don't panic because of lack of knowledge, but because of lack of experience. You can know a lot about the market, talk with someone, read a book and so on. But lack of experience punches you in the face when you see huge red candles on the screen thinking your investment is turning into the Titanic. If you then have experience, you will stay calm knowing that this happened before and chances for recovery are great.
