What does FOMO mean?
FOMO stands for "fear of missing out": the worry that others are profiting from a rising asset and you will be left behind. In crypto it describes buying because a price is climbing rather than because of what the asset is.
What it means for you
FINRA warns against investing based on FOMO. Scammers use it deliberately, with countdowns, "last chance" offers and screenshots of gains, because haste stops people checking. A crypto payment cannot be reversed once sent, so a rushed purchase from a scam usually cannot be undone.
How it works
FOMO works by replacing checking with hurry. FINRA lists it as a reason not to invest. Fraud schemes build it on purpose: pump-and-dump groups post countdowns and stories of famous backers that create false urgency, and FinCEN describes pig-butchering scammers telling victims they will lose the opportunity if they do not invest by a deadline. In each case the deadline is invented to stop the buyer pausing to verify the platform, the coin or the person. Since a crypto payment usually cannot be pulled back once sent, the time pressure is the part that turns a doubt into a loss.
