## Definition

FUD stands for fear, uncertainty, and doubt. In crypto it usually labels negative news, claims, or social media posts about a coin or platform. The accusation can be fair or unfair: some FUD points to real problems, while some is simply uncomfortable information for holders.

The best response to FUD is to read it carefully and decide whether the underlying facts hold up, not just to dismiss it.
