"FUD" is an acronym that stands for "fear, uncertainty, and doubt." It is used to describe the spreading of negative or false information, with the intention of creating fear and uncertainty about a particular investment or product.
In the context of investing and finance, FUD is often used to describe the tactic of spreading negative information about a stock or cryptocurrency with the goal of causing its price to decrease. This can be done through various means, such as false or misleading statements, rumors, and manipulation of social media or news outlets.
In the crypto world, FUD is a common tactic used by malicious actors to manipulate the market and cause panic selling of a specific coin or token. This can be done by spreading false information about the project, the team behind it, or the technology it uses, or by spreading rumors and speculation about government regulations or other negative news.
