Here's something that should be humbling: the people who lose the most money in crypto aren't the dumb ones. They're often smart, capable, rational people — who made spectacularly bad decisions because of what a bull market does to the human brain.
Intelligence doesn't protect you from psychology. In fact, sometimes it makes it worse, because smart people are better at rationalizing their emotional decisions. If you want an edge in crypto, understanding your own mind during a bull run is worth more than any technical indicator. Let me walk you through what actually happens up there.
The FOMO engine
It starts innocently. Prices are rising. Your friend mentions they're up big on something. You see screenshots of gains online. And a feeling creeps in — fear of missing out. FOMO is the single most expensive emotion in investing, and a bull market is a machine designed to manufacture it.
The insidious thing about FOMO is that it feels like logic. "Everything's going up, I should get in before I miss it" sounds reasonable in the moment. But it's the emotion driving the thought, not the other way around. And FOMO systematically pushes people to buy at exactly the wrong time — near the top, when the excitement is highest and the risk is greatest.
Greed rewrites your risk tolerance
In a calm market, you might tell yourself you're a sensible investor who takes measured risks. Then a bull run hits, your portfolio is up, and something shifts. The gains feel easy. The wins make you feel smart. And slowly, quietly, your definition of "reasonable risk" expands. Positions you'd never have taken six months ago start to feel conservative.
This is greed doing its work, and it's dangerous precisely because it feels like confidence. You start believing you've figured it out, that you have a special touch, that the normal rules don't apply to you this time. Every green candle reinforces the illusion. The market isn't making you smarter — it's making you reckless while convincing you you're brilliant.
The story everyone tells themselves at the top
Near the peak of every bull market, a comforting narrative takes hold: "this time is different." There's always a reason it'll keep going. New adoption, new technology, a new paradigm, permanent growth. The story is always sophisticated and often contains real truths, which is what makes it so persuasive.
But "this time is different" is one of the most expensive phrases in the history of markets. It's the sound of people talking themselves out of caution at the exact moment caution matters most. When you catch yourself believing the rules have changed and the upside is unlimited, that's often precisely when they haven't and it isn't.
Why selling is harder than buying
Here's a cruel twist of psychology. Buying during a bull run is easy — it feels great, everyone's doing it, the momentum carries you. Selling is agony. If you sell and it keeps going up, you feel like an idiot who left money on the table. So people hold, and hold, watching gains they could have locked in evaporate on the way back down.
The pain of selling too early feels worse than the pain of not selling at all — right up until it doesn't. This asymmetry is why so many people ride a position all the way up and all the way back down, ending up with nothing but a story about how they "were up big at one point."
How to actually protect yourself
You can't eliminate these emotions. Anyone who tells you they're immune is lying or hasn't been tested yet. But you can build systems that protect you from yourself.
The most powerful one is deciding your plan BEFORE you're emotional. Set your entry, your targets, and crucially your exit strategy when you're calm and rational — then follow the plan when the emotions hit, instead of making decisions in the heat of the moment. A written plan is a message from your rational self to your emotional self.
Take profits on the way up, in pieces, rather than trying to nail the exact top. Nobody catches the perfect top consistently. Selling portions as things rise means you lock in real gains and remove the impossible pressure of perfect timing. You'll never sell the exact top — and accepting that is freeing.
And build in friction. The easier it is to act on impulse, the more impulse decisions you'll make. Sleep on big moves. Wait 24 hours before FOMO buys. Make the emotional decision slightly harder to execute, and a lot of bad ones die in the delay.
The uncomfortable truth
The market is, in a sense, a machine for transferring money from the emotional to the disciplined. The technology, the charts, the analysis — they all matter. But the biggest edge available to an ordinary investor isn't a secret indicator. It's the boring, difficult work of managing your own psychology when everyone around you, including the voice in your own head, is losing theirs.
In a bull market, everyone looks like a genius. The genius part isn't making money while everything goes up — a rising tide does that for you. The genius part is keeping it. And keeping it is a psychological skill, not an intellectual one.
Master your mind, and you're already ahead of most of the market. Not financial advice — do your own research and never invest more than you can afford to lose.
