FUD (fear, uncertainty and doubt)
Short for ‘fear, uncertainty and doubt’. It refers to news that stirs up sentiment against Bitcoin. Not every criticism is FUD – some warnings are justified.
Alsofear, uncertainty and doubtspreading FUD
FUD stands for ‘fear, uncertainty and doubt’. In the Bitcoin community, it’s a label for news that stirs up sentiment against Bitcoin, such as ‘Bitcoin is going to be banned’ or ‘Bitcoin is dead’.
Origin
The term became known in the computer industry: in 1975, Gene Amdahl, who had left IBM and founded his own company, used it to describe how IBM salespeople deliberately unsettled customers.[1] So it meant uncertainty spread on purpose, not any piece of bad news.
FUD or legitimate criticism?
The label can be stuck on any uncomfortable criticism. But some warnings are justified, for example about price swings or scams. Four questions help you tell the difference:
- Source: a law, an authority, a study – or a rumour?
- Evidence: does the claim give a date, a figure and proof?
- Interest: who benefits if you believe it – or if you dismiss it as FUD?
- Consequences: what actually changes for you?
