To make money from investments, you need to buy before the bubble forms. Then wait for the bubble to appear and exit when it expands. However, due to human greed, most people who make money from the bubble only see it as unrealized gains and are unwilling to exit. Because the process of creating a bubble is so enjoyable, with just a little blow, overnight, your assets might double. How to distinguish a bubble is quite simple; just label your emotions. If you wake up today and see your assets have increased significantly, and you feel very good, you should be wary of the bubble.
