The crypto market behaviour is very emotional. People tend to get greedy when the market is rising which results in FOMO. I also think this has to do with experience. A young trader just starting out could have difficulty in accepting that s/he should not be attached to a project (either for long term or flipping). I was one of the those people that dumped their $Links recently, I swapped it to BTC on Changenow and moved on. It still got higher after then but I didn't regret it. You never lose once you made profit and that has always been how I think.

Great post, I should share with amateur traders.
