Token burning and how it works
Token burning occurs when cryptocurrency is intentionally sent to an unused wallet address in order to remove it from circulation. The address, which is called a record address or eater address, cannot be accessed or assigned to anyone. Once a token is sent to such an address, it disappears forever.
The project burns its tokens to reduce the total supply. In other words, it creates deflation. It is explained by the growth of the remaining tokens' value as far as assets tend to increase in value whenever the circulating supply drops and they become scarcer.
