Trading isn't a quick way to get rich because it's tougher than it seems. Success lies in knowing the craft, controlling emotions and managing risks you can afford. Mistakes often come from thinking it's easy or relying on a couple of YouTube video so we should always verify our facts and do not always be impuslive in making decisions
You have said very right things about trading, because trading does not always work as before or as it has happened before in the market. So every trader really has to strengthen his knowledge and resistance to risk when market conditions start to go the way he didn't want before, so looking at references from YouTube videos for trading matters also won't guarantee that a trader will immediately get better results. Because the video was deliberately uploaded to attract more attention from many people whose profession is traders.
