Unfortunately, a rather small percentage of people understand that you need to look at other people's mistakes and learn from them. And no matter how much folk wisdom talks about this, but the majority, until they go through the path where absolutely all mistakes will be (reducing their deposit in this way) will not be able to become wise people, and most people, in general, will not even be able to draw a conclusion from this, therefore they will never be able to become successful investors and especially successful traders.
look at this my dear friend, summonerrk is also valid in real life not just in betting
Even in real life, seeing how others make mistakes, no one cares to learn and not make the same mistakes.
Don't mention it, it seems very unlikely that what you're asking for will come true.
