Newbie traders get involved in trading with what they've heard from other platform that trading isn't hard.Lets call a spade a spade, trading is hard and the chance of losses is more than investing,so when newbie traders think trading isn't hard and skip the process of learning the fundamental and analytic work of trading that's where everything on trading will look so frustrating to them.
Newbie traders should be informed that trading is less risky if only they acquire a legit knowledge on trading, with that it will help to ease the chance of losses.
If they only listen to the platform about trading and they continue to decide to trade, of course they have made the wrong decision and for everyone who decides to trade, they first prepare their knowledge about trading well, after they understand it well, then they can try to trade with a little capital first while they continue to learn about trading, because if they keep trying with large capital and if they fail in the trades they make, of course this will make them very frustrated.
You are right, every beginner of course they must first understand trading well and they must also know that it is very risky for every beginner who trades without knowledge, there is a very big possibility that they will lose the funds they use to trade.
