Buy high, sell low: why you keep doing the opposite

I have a friend who, in the rally a couple of years back, watched people in his group chats post profit screenshots day after day. He held back for almost two weeks, then one Friday night finally made up his mind and put the money he'd set aside in, all at once. The moment he bought he felt deeply settled, like he'd finally caught the train. As it turned out, the spot where he bought was, looking back, right around the high of that whole run. When it then fell, he held for over a month, until one late night he read an article titled "the bear market is here," and the next morning he cleared everything — selling at a downright ugly low. Buy high, sell low, there and back; he executed it pretty much by the book.

I can't laugh at this at all, because I've done almost exactly the same thing myself. Only slowly did I work it out: chasing the top and cutting the bottom isn't a few people being clumsy, it's nearly the default setting of human nature. When the market rises, one force pulls you in; when it falls, another force pushes you out — and both forces happen to point the wrong way. This piece pulls those forces apart and explains them, then gives you a few clumsy, useful ways I rely on to slow emotion down.

The ugly truth first: crypto swings violently, halving in a short time or worse is the normal state of this market, and you can absolutely lose the money you put in. So everything below rests on one premise — spare money only, decide for yourself. This is not investment advice, and I won't tell you what to buy or whether to buy.

A loop almost every beginner replays

You've most likely been through, or are going through, this loop: when the market is quiet you're not interested, it feels dead; when it rises and people around you start making money, you're tempted; when it's risen until the whole screen is rags-to-riches stories and even people you know who never touch crypto are talking about it, you finally can't hold back and dive in — usually already near a local high. Then the market turns down, and at first you think "just a pullback," then your account is red every day, and at some point the pain breaks you and you cut at the worst low. Not long after you sell, it climbs back, and you want to smash your phone.

This loop is universal because what drives it isn't your level of knowledge, it's emotion. You can read all the analysis you want, but the moment real money is moving up and down in front of you, reason is often absent. So fighting buy-high-sell-low isn't about "learning more," it's about seeing clearly which emotions are pushing you, then fitting them with speed bumps. Let's go through them one by one.

Buying the top: how FOMO drags you in

First, the force that pulls you in, which has a popular name: FOMO. At heart it's just "fear of missing out" — you watch others make money and you can't sit still.

Term FOMO: short for Fear Of Missing Out. The urge, when you see others making money or the market rallying hard, to rush in afraid of being left behind. It isn't judgment, it's emotion.

The worst thing about FOMO is that its intensity tends to move in lockstep with the price level. The higher the market pushes, the more profit stories there are and the louder social media gets, so your FOMO grows too — which means the moment you most want to buy is, again and again, the moment of highest price and greatest risk. When the market is quiet and the price is sitting at the bottom with nobody discussing it, you have no urge to buy at all. Your buying impulse is pushed along almost by the price itself, and the direction is backwards.

There's a hidden booster too: what you see are the "survivors." The people posting their trades on social media are always the ones who made money; those who lost mostly delete the app quietly and say nothing. You think "everyone's making money and I'm the only one not on board," but what you see is a filtered, badly distorted picture. Using that distorted picture to force yourself into a heavy position chasing the top is one of the easiest traps for beginners.

Careful "This time is different, it's a once-in-a-lifetime chance" — at every top, the last person to buy in is thinking exactly this. The more you feel "if I don't get on now it's too late," the more you should suspect it's FOMO making the decision for you, not you making the decision.

Selling the bottom: loss aversion and panic conspire

Now the force that pushes you out. After buying near the top, the market falls, the account starts losing, and two things join forces to push you toward cutting: one is loss aversion, the other is panic.

Term Loss aversion: a well-known idea in behavioral economics, that the pain of a loss is usually clearly greater than the pleasure of a gain of the same size. Put simply, the sting of losing $100 is stronger than the joy of making $100.

Loss aversion means every notch of red in the account, the pain you feel is amplified. That pain pushes you to want it to "stop right now," and the most direct way to make it stop is to sell. The trouble is that the moment the pain is worst is usually the moment the price has fallen hardest and is closest to a local low — so once again you sell precisely near the bottom. On the way up FOMO buys you in at the top; on the way down loss aversion sells you out at the bottom; put those two together and you get "buy high, sell low," repeated cycle after cycle.

Here's a especially important distinction: panic selling and a rational stop look very alike, but they are not the same thing at all. A rational stop is a rule you wrote before entering — exit at a certain price, execute when triggered, no connection to your present mood. Panic selling is a reflex outside the plan, forced out by present pain. To tell which one you're in, there's a simple question: am I selling now because "my pre-set rule triggered," or because "I just can't take it anymore"? If it's the latter, it's basically panic. How to set a stop that neither gets swept by noise nor fails to protect you is its own topic, in how to set a stop so it isn't swept over and over.

Anchoring: fighting a price that no longer exists

There's another, quieter, but equally damaging trap, called anchoring. It isn't as violent as FOMO and panic, but it can silently distort your judgment for a very long time.

Term Anchoring: people making a judgment are easily "anchored" by the first number they encounter, and every later judgment unconsciously circles that number. In trading, the most common anchors are "my buy price" and "the highest price it ever reached."

Here's a very common example. You bought at $100, it fell to $70, and you flatly refuse to sell, on the grounds that "I'll leave when it's back to $100." But the market has no idea, and no interest in, what your cost was. Your buy price means nothing to the market; it's just an anchor carved into your head, keeping you from facing the question you should actually ask — at this price, right now, is it still worth holding? Likewise, "it hit $200 last year, so $70 is too cheap" — that "$200" is also an anchor, and a past high doesn't mean it's bound to return.

The harm of anchoring is that it lets a fictional reference point replace real judgment. The rational question is: given today's information and today's price, if I didn't already hold this, would I buy it right now? If the answer is no, then the only reason you're holding it may be that anchor — refusing to accept the loss. Refusing to accept a loss is not a reason to hold, just as FOMO is not a reason to buy.

A few clumsy ways to slow yourself down

Having seen these forces, the key question arrives: how do you fight them? My answer may disappoint you a little — there's no clever trick, only a few clumsy ones. But what these clumsy methods share is this: they all jam a gap between you and your impulse. What impulse fears most is being slowed down; slow it a little and reason gets a chance to come back.

One: force a waiting period before ordering. When you see something that itches at you, that you want to buy this instant, don't move — set yourself a rule: wait a day before deciding. Spend that day doing nothing, just letting the "if I don't buy now it's too late" feeling cool off. If a day later you still think you should buy and can explain why, then buy, no harm done; if a day later you can't even remember why you were in such a hurry, congratulations, you just saved yourself a top-chasing buy. This waiting period works especially well against FOMO, because FOMO has a shelf life — past that point the urge deflates.

Try it Set a real delay, not a silent "let me calm down." For example, jot the asset you want into a note with the date, and agree to come back after a full 24 hours. A physical wait is far more reliable than willpower.

Two: write your trade reason before ordering. Before buying, in a line or two, write three things clearly: why I'm buying, the loss at which I'll exit, and where I'll sell. If you can't write them, it means you haven't actually thought it through — so don't buy. The beauty of this move is that it forces you to turn a vague impulse into concrete words, and a lot of impulses, once they have to be written down, show their true face — you'll find the only reason was "everyone else is making money." Writing it down has another benefit: when the market swings and you start itching to act, you can look back at the reason you wrote and check whether anything has actually changed.

Three, and most important: set the rules in advance, don't change them in the heat. All the rules worth setting — how much per trade, where the stop goes, when to sell — get set while you're calm and under no position pressure, and written down. Then when the market comes, up or down, your job is only to execute the rules already set, not to make new decisions on the spot. Why is this one the most important? Because the moment emotion is strongest is exactly the moment you should least make decisions. The rules you set in calm waters are a letter the clear-headed you leaves for the agitated you.

Careful The most dangerous moment is when, in a big move up or down, the thought pops up: "this situation is special, I need to tweak the rules." Nine times out of ten, that "special" is emotion looking for an excuse. Rules can change — but please change them after the close, when you're calm, never mid-session, when you're worked up.

None of these three is profound; they're a little crude, even. But crude as they are, they're all doing the same thing: creating delay and friction between impulse and action. You don't need to become a person without emotions — that's impossible, and unnecessary. You only need a checkpoint between your emotions and your fingers.

In the end, you're trading against yourself

Many beginners think they trade badly because they don't know the technicals, can't read charts, or aren't plugged into the news. But after paying plenty of tuition, I've come to feel that for most ordinary people, the root of losing money isn't "not knowing," it's "knowing and still not being able to do it." You know perfectly well to buy low and sell high, yet on the scene FOMO has you buy high, loss aversion has you sell low, and anchoring has you cling on. The real opponent isn't on the other side of the screen, it's in your own emotions.

So this whole piece really only said one thing: admit you'll be swayed by emotion, then build the defenses in advance. Wait a day before ordering, write your reason first, set rules and don't change them in the heat — these lines won't catch every mistake, but they'll help you avoid the biggest, most fatal cases of buying high and selling low. Take it slow, and learn not to lose first. Next you can read how much to invest on your first buy, and keep your position in a range you can sleep with — a lighter position naturally makes emotion much easier to manage.
