An acronym that stands for ‘fear, uncertainty, and doubt’, FUD is a commonly used term in the cryptocurrency world. It can be interpreted as a strategy used to negatively impact a project, and generally is used to spread negative sentiment about a project in the form of false or misleading information.
A person who FUDs can be referred to as a FUDster, and there are many reasons why someone would FUD a project. Often, individuals do this because they feel as if there are glaring issues with a project and it has undeserved attention. Another reason is to manipulate the market.
FUDsters create FUD with the intention to make the value of a project fall, thus creating a cheaper entry price for themselves.
