Chapter 12 is the conclusion of the book. The chapter starts by arguing that the bubble triangle can explain why the cryptocurrency bubble occurred in 2017. It then asks whether the bubble triangle is a good predictive tool. The answer to that question is yes, but bubbles are still difficult to predict because the sparks are difficult to discern. The bubble triangle is also able to predict which bubbles will be destructive (politically sparked bubbles with high bank lending) and which will be useful (technology sparked bubbles with low leverage). The chapter then moves on to look at what governments could do to prevent bubbles. However, since political bubbles are often created because they are in the government’s interest, governments cannot be relied upon to take these measures. The question then arises as to whether the news media can alert investors to the presence of bubbles. The answer to this question very much depends on whether they have the incentive to do so, and this incentive appears to be diminishing over time. The chapter concludes by arguing that investors need to build broad mental models, which include history, if they are to have any chance of predicting bubbles.
