We will always hear this kind of stories especially during the bull run, some people will lose, while some people will make money. The sad reality is there's a lot of newbies who are convinced that trading or investing is profitable, but in reality, it depends on your knowledge and skills, and it's like gambling where one could make or lose.
yes it looks faintly like gambling, but I don't call it that, this is a trade where we trade and expect big profits but trading also sometimes trading can also bring losses, which is normal. like what you say they lack knowledge and are too reckless they only think of big results and don't know how to analyze it.
