Ordinary nobody goes into a business or investment with the mindset of losing, but however for the business of trading it is inherently required that as a beginner you must get a mentor or somebody who teaches you ways and means on how to go about trading, so in teaching you, he will tell you about the fact that you will get losses along the line, because the market variance and force's can work against your predictions anytime.
So for me your mentor should be your guide so as to reduce those risk, so you don't just walk into trading without caution inside you.
At the same time some of these mentors especially those one on YouTube that only want their videos to be the best, they don't speak much about losses only how to make profit and you'd agree with me that many who only think of getting more profit are those who uses their imagination to start up trading, they just picture themselves to be at the top above every other starter.
I think getting someone like a mentor shouldn't be a problem but the issue is how good is the mentor because everyone needs to be careful not to be in the losing side of trading, not everyone we call mentor has what it takes to guide someone to the right direction.
I must agree with you because I have seen many YouTubers who only try to get views of their videos. They only present the gain but I hear very little from them about the loss. I'm sure those who follow those influencers and conduct trading will increase their because they just show you about the profit. Trading does not go through any specific formula. Here you have to change the strategy regularly. But I wouldn't say that there is nothing to learn from it either. There are many people who highlight various issues related to trading. A new trader must have knowledge of many things to learn. It is good for those who are new to have a mentor in the first stage, but you must also understand that in trading, it is appropriate to consider that there will be not only profit but also loss.
