WHAT IS 'FUD'?
FUD is an acronym for fear, uncertainty and doubt. It is a marketing term that is often used to cast a shadow over a competitor's product when your own is unable to compete.
It is a strategy intended to make a company's customers insecure about future product plans with the purpose of discouraging them from adopting competitors' products. For example, "You can try using X instead of our product, but you may lose all your data."
FUD is a technique used by larger companies who have a large market share. The FUD acronym was first freely defined by Gene Amdahl after he left IBM to found his own company, Amdahl Corp, with this statement: "FUD is the fear, uncertainty, and doubt that IBM sales people instill in the minds of potential customers who might be considering Amdahl products."
In crypto, the whales with their large financial power can create an imaginary 'negative cloud' over a project, when panic sets in, the nobs sell off and the whales go to the bottom and buy off. Then create a 'positive cloud' over the project, when FOMO sets in they sell of.
