FOMO (Fear Of Missing Out) should be in this list, too. For newcomers, FOMO means that you chase a certain currency when it starts pumping. The thing is that all whales and professional traders are already in the game, so when newbies buy skyrocketing coin, 99% that it will start falling immediately. Don’t try to chase lost opportunities. Better, learn and predict further pumps. Also, as for greed, it really may be useful. As the silver rule: «Be afraid when other traders are greedy and be greedy when other are afraid». This works.
