“FUD” is an acronym that stands for “fear, uncertainty and doubt.” In the context of cryptocurrency markets, FUD refers to the spread of negative information or rumours with the intention of creating a sense of fear, uncertainty and doubt among investors and traders. The goal is often to manipulate market sentiment and drive down the prices of particular cryptocurrencies.
FUD can take various forms, including false or exaggerated news, misleading statements and the spreading of unfounded rumours about a particular cryptocurrency or the overall market. It’s a tactic that can be employed by individuals or groups to influence market behaviour and cause panic selling.
