Yes your right ! Most newbies don’t think of how much they could loose , they think so how much profit they can make which in turn makes them to take steps which leads them to having a loosing trade , risk management is key. Since the market market can’t be predicted it’s always better to manage risk so as if the worse happens you’d be on a safe ground buh greed won’t allow most traders know this little fact .
Of course, the newbies are just full-time employees in real life and heir worry is just a delay in getting paid and having a pay cut, there has never been an element of losing most of their salary from their company, hence, they will not have the expertise of an investor, more precisely, their trading theory is an old version and has not yet added new criteria such as skill and risk management. A fact that we should admit is that the number of people who know trading well is still too small, almost only know here with the belief of holding to death without thinking about disaster prevention.
