What is Fear Uncertainty and Doubt (FUD)?

Fear, uncertainty, and doubt (FUD) is a term commonly used in the context of blockchain or general finance. It signifies that overall market sentiment is fearful, uncertain, and doubtful. FUD generally increases among market participants during a bear market when a substantial monetary drop in a number of stocks or the entire stock market takes place. In relation to blockchain, FUD is typically very high when the price of bitcoin (BTC) drops significantly during a very short period of time, which typically brings other cryptocurrency market valuations down in price with it.
