Pumping refers to manipulating the market to cause the price of an item to rise rapidly. Pumps are often initiated by some manipulators or community members. They will use the community to spread propaganda information and incite investors' enthusiasm for a certain project, thereby driving up the price of the project. Pumps tend to be short-lived, and prices don't usually increase sustainably. Investors should be wary of the pump phenomenon and avoid being deceived.
