The land fever is one of the specific examples showing the two-sided effect of crowd psychology. On the positive side, crowd psychology can bring immediate profits to many investors if they research, calculate and carefully study the market based on their financial capacity. But on the negative side, the virtual land fever will cause many people to fall into traps, leading to struggling to pay monthly debts, even falling into a miserable situation because of debt.

Crowd psychology can help spread good messages in society. These are good, humane actions that deserve to be praised, and thanks to the crowd effect, these actions are spread faster. For example, saving people, sharing difficulties, doing charity.

But on the negative side, the endings are extremely unpredictable, but most of them leave behind sad consequences. In fact, there are many people who are suddenly "attacked" on social networks with untrue stories, falling into anxiety disorders, suffering from crowd phobia or even committing suicide just because of negative pressure from social networks. In addition, there are countless stories of consequences from crowd psychology.

However, crowd psychology is a reality that exists in today's modern society. We cannot eliminate this phenomenon from life, but we need to control it. The most important thing is to build for yourself a good awareness, sober enough to identify positive and negative phenomena in life.
