Group Fanaticism [EPUB ebook] 

This book is a factual presentation of the group psychology of "the crowd". We have always only read the theoretical part of "the crowd". This book humorously yet solemnly narrates multiple economic bubbles, scams, and shocking popular frenzies that occurred on the European continent, covering topics such as investment and speculation, speculation bubbles, financial crises, stock market disasters, alchemy, and prophecy. These real yet absurd cases in history help people more intuitively understand the characteristics of groups, read the public psychology, and comprehend social phenomena such as real estate bubbles, stock market bubbles, and the crazy Bitcoin.
