Why do this cognitive enhancement class? I believe that only by improving our cognition can we make money. If I just tell you what points to buy and sell, then everyone in the world would be billionaires from trading. I think investing is a long-term career for the second half of life, and this 50-lesson course that I spent a year creating may seem time-consuming and labor-intensive, thankless, but once completed, it can be used for a long time. In the future, we just need to periodically update some small chapters, and it will definitely be rewarding because the breadth of knowledge must be comprehensive, not just isolated points. It may be publicly available for free in the future, but it is unlikely in the short term, after all, it has consumed a lot of effort. (Value Investor Community)$BTC
