Sometimes quite a lot of people are fomo in things like this just because they see it once and immediately conclude about the benefits that are said to be easy, even though it is not like that in reality. In terms of trading, knowledge or science as you said is quite important because losses in this case can be said to still be prevented from happening and it depends on the knowledge and science that we have about trading.
You are right, there are many factors that need to be considered in trading, generally they must be able to manage finances well and other factors also need to be considered, the goal is to prevent major losses. For people who only think about their profits, they may continue to do it even with minimal knowledge.
why most people have such expectations because maybe social branding can also be blamed why people have such expectations, just look at the brokers who advertise them saying that trading seems very easy and also trading is considered a financially free job so that people think towards results not on the process, look at the traders most of them do flexing on their social media but do not show how many failures and losses they experience, therefore it is necessary to show a lot of education rather than results so that people have the power to think first before fantasizing.
It is true, I who spend most of my daily life on social media and yes, not once or twice I have seen advertisements about this saying that trading is an easy thing to do, and yes for people who are fomo this can certainly attract their attention. With one of my friends who is still in high school, he has recently been interested in seeing advertisements like this and he began to learn to understand it well I had time to say fomo, but if he is serious, hopefully he can succeed.
Not only in this case, but indeed many people who are involved in various things do not show their failures but with the results they tend to show, so there is also truth in saying that other people will not care about the process but they will see the results. This is a real statement in my opinion.
