It's true, so many traders don't show their losses, they only show when they are in huge profit and also show off their cares luxurious lifestyle and all of those show off is to entice the learner to come and patronize them and buy their courses or pay for personal classes. Something happen around 2020 when I was learning forex trading and since then, I took a decision never to pay anyone to learn trading again. I have not paid anyone to learn anymore but so far, I have become better off without paying anyone and when am fully settled into the skill, I will always  tell people the bitter truth in trading and one of them is that, "As a beginner if you have not blown 💣💣 your account a few times, then you have not started." So, never start trading with a huge capital, go with a small amount first and see how you can scale that capital to a50x or 100x without blowing it up. It when you are trading with a real capital that's when you greed and emotions will be tested. 
Secondly, if you feel that you can easily become rich in trading and archive all the flashy things you ever dream of, then you might never get to archive it because good things don't come easily.
