Fear of missing out on an opportunity: the impulse to buy an asset just because it's rising and everyone else seems to be making money but you.
FOMO (fear of missing out) is the fear of missing out on an opportunity: the impulse to buy an asset just because it’s rising and everyone else seems to be making money but you.
The scene repeats every cycle. An asset rises 40% in a week. Your group chat fills up with screenshots of gains. Someone who never talked about investing before asks you how to buy. And then that little voice shows up: “if I don’t get in now, I’ll miss it.” That’s FOMO, and it’s probably the number one cause of losses among people who start investing in crypto.
The term was born in psychology (coined by strategist Dan Herman in the late 90s and popularized by a 2004 article by Patrick McGinnis) to describe the anxiety of watching other people’s lives on social media. Markets adopted it because it precisely describes what happens when a price shoots straight up: the decision stops being financial and becomes emotional.
What FOMO does to your head when everything is rising
FOMO runs on two engines. The first is social proof: if a lot of people are buying, your brain assumes they know something you don’t. The second is regret aversion: it hurts more to imagine you could have made money and didn’t than to lose money having done what everyone else did. Combined, they produce impulsive purchases right at the top.
Social media amplifies both engines. Nobody posts their losses, so the content you see is skewed toward gains, which distorts your perception of how easy it is to make money. And the crypto market, which trades 24 hours a day and can move 20% in a single day, compresses into hours an emotional process that in other markets takes months.
The FOMO cycle, step by step
It almost always follows the same script. An asset starts rising for a concrete reason (or none at all). Media and social networks amplify it. The first buyers post their gains, which attracts more buyers, which pushes the price up further. In the final phase, the people who resisted for weeks and couldn’t hold out any longer jump in: they buy at the point of peak euphoria, which is usually near the top.
When the rally runs out of steam, the earliest buyers sell and lock in gains. The price falls, the latecomers panic and sell at a loss, and the cycle closes. The cruel part is that FOMO also works on the way down. The same impulse that made you buy at the top pushes you to sell at the bottom.
Dogecoin’s FOMO in May 2021
Dogecoin rose more than 12,000% between January and May 2021, driven by Elon Musk’s tweets and a flood of viral content. The peak came on May 8, the day Musk appeared on Saturday Night Live: millions of people bought that week expecting “the final push.” It went exactly the other way. Six weeks later, DOGE had lost more than 70% of its value. Whoever bought based on analysis had an exit plan; whoever bought out of FOMO only had hope.
How to invest without FOMO
The defense against FOMO isn’t willpower, it’s process. Deciding how much to invest, at what price to enter, and when to exit before you even open the app takes the decision out of your hands in the heated moment. Periodic fixed-amount purchases (DCA) eliminate the question of “is this a good time?” because you always buy. And scheduled orders execute your plan even while you’re asleep.
A simple rule helps too. If your reason for buying is that the price went up, you don’t have a reason. Yesterday’s price isn’t an argument about tomorrow’s value. The best opportunities usually show up when nobody is talking about the asset, not when it’s trending on X.
