Highly recommend all brothers to watch this "The Underlying Logic of Investment." This is a work that Meng Yan spent two years refining, and I believe it is the most practical and down-to-earth investment science popularization film currently available. In just 30 minutes, you can thoroughly understand the fundamental logic of currency, economy, supply and demand, and investment. Especially for those who are still struggling with fear, greed, losses, and confusion, watching this will definitely open your mind and clarify your thinking instantly.
