Your assertion is accurate, yet the majority of those who lose money so easily do so because they lack information and only consider the profitable aspect of trading while ignoring the costly aspect, loss. Everything required information in order for us to avoid being on the wrong side of it. You cannot invest in anything if you decide not to trade because you are afraid of losing everything, then you will never be independent.
Those who lose money sometimes isn't because they lack the proper information, they are just lazy to implement such available information to build on their self, they will read and still ignore even when there is red flags everywhere. Have you noticed that despite that learning trading is online and tutorials are all over the internet, people prefer to trade blindly without doing all the required analysis in technical and fundamental form.
The thing is, it's not everyone that will learn because they want to have their things the easy and life don't work in that form, you have to give something to have what you want, either by sacrifice or by money.
