What is token burning and why does PancakeSwap do it?
Token burning is a strategy adopted by many cryptocurrency projects to reduce the circulating supply of their native token. This process involves sending a certain amount of tokens to an address from which they cannot be retrieved or used, effectively removing these tokens from the market. The primary purpose of this action is to create a deflationary effect, increasing the scarcity of an asset while maintaining the value of the remaining tokens. In the case of PancakeSwap, the burning of 8,587,275 CAKE tokens is part of a continuous effort to manage the supply of the platform's native token. By reducing the supply of CAKE, PancakeSwap hopes to foster greater demand, which could potentially increase the value of the tokens that are still in circulation.
