The story
The timing of an episode of the anime “FX Warrior Kurumi-chan” lining up with real-world news reports of an FX account hack — “4.3 million yen → 6,000 yen” — became a hot topic on 5ch. The thread moved from explaining how the actual unauthorized-login scheme worked into a discussion of the psychology behind why Kurumi-chan can’t cut her losses in the show. Replies explained the difficulty of locking in a loss through the lens of behavioral economics, while others joked around using coin-flip probability theory.

And here the anime was hyping things up, only for this to pour cold water on it.
If it's true they even built systems that didn't need to be in PHP that way, just because it's easy… that's something else entirely.
This is bad news. Will they even compensate for it…?

Well, the winning position just carries over into next year, though.
For individuals, unrealized gains aren't taxed unless you actually lock in the profit.

Seikei beats Rikkyo after all, huh (comparing Japanese private universities)
And this is the reaction to just 20x
Why are you hesitating?
Probably, if she hadn't had a part-time shift and had gotten home before her dad, she wouldn't have been caught. Still a mystery why the monthly cash stash under the mattress had grown into a ¥1 million bundle.
Theory: the timing of coming home from her part-time job had nothing to do with it. To begin with, Kurumi's assumption about the end-of-month deadline (6/26~) is wrong in the first place — normally, salary gets paid in on the 25th…
Because they weren't living that kind of hand-to-mouth, bike-to-the-ATM-the-day-payday-hits lifestyle just to cover living expenses or top up the cash stash.
Keeping cash stashed at home was probably just his thing.
Because it's safe from cyberattacks.
You'd keep around ¥3 million on hand, right? It's silly to eat ATM or bank fees every time you suddenly need cash.
If a coin lands heads 10 times in a row, there's a good chance that coin is rigged to land heads — so it's more likely to keep landing heads after that too.
Lol wait, was this actually a bit from the Kurumi-chan manga?
I see…
So this is how easy it is to rake in huge profits with FX, huh lol
Kurumi-chan is definitely being sold off for this exact same kind of speculative reasoning too — so why isn't she getting slammed for it?
Probably because with investing, you reap what you sow.
Logging out properly is actually the key thing. Even if you set a complex, unique password for every site and use multi-factor authentication,
staying logged in is what gets you hijacked.
It's not the user's fault at all — it's the site cutting corners — but since that's become the norm, it's not getting fixed anytime soon.
Especially with financial institutions — don't they automatically log you out after about 15 minutes of inactivity?
In this case, because the MT4 auto-trading tool runs on GMO's servers constantly watching for triggers to buy and sell automatically, MT4 needs to stay logged in to the FX company at all times by design.
Simply put, it's because she only ever thinks about prices going up. It's the same as someone who's never prepared for an earthquake freezing up when one actually hits.
The show explained the psychology behind this before — people can lock in a profit easily enough, but very often struggle to lock in a loss. Rather than accept a certain loss, people tend to gamble on wishful thinking that the market might turn around, even at the risk of the loss growing bigger.
Say you've dumped ¥80,000 into a pachinko machine that's still capable of a big comeback, and you've still got ¥20,000 left in your wallet — could you really walk away and lock in that ¥80,000 loss?
I tried this myself and yeah, it came out roughly like that, but since both options have the same expected value, it's really just a matter of preference.
Failing to cut your losses is clearly a losing move, so a survey like this only means something if it shows people picking the option with the lower expected value.
I think the point is that if the expected value is the same, you'd naturally expect something close to a 50/50 split, yet a big gap shows up instead. If the result had people picking the lower-expected-value option, some people would probably start doubting the survey itself — so this version has its own value too.
This didn't really click for me as 'the reason people can't cut losses.' What about people who can't take profits either?
FX, on the other hand, is a zero-sum bet on currency ratios, and margin trading on top of that makes it a punishment game where you also risk losing your capital.
You can tell FX believers are pretty foolish, right? lol
As long as you can hold on. That's exactly the difference between Kurumi-chan's theory and your own actual money.
If it plays out over a decade (though who can really tell), not cutting your losses while averaging down turns into collecting dividends.
The stock market as a whole expands, but individual stocks don't necessarily work that way…
I do think FX is foolish, but the idea that the market keeps growing forever is also an illusion — same as how a pyramid scheme can't possibly keep paying out forever.
Background and Key Points of This Topic
“FX Warrior Kurumi-chan” is a series centered on FX trading, and the main character’s episodes of huge losses frequently become talking points. The “can’t cut losses” phenomenon discussed in the thread is commonly explained in behavioral economics through loss aversion (prospect theory), a psychological bias, and the thread’s discussion largely followed that framing. Meanwhile, the opening report about an account going from “¥4.3 million to ¥6,000” is a separate, real-world incident unrelated to the show’s fictional loss storyline, reportedly stemming from how auto-trading systems like MT4 keep sessions logged in at all times. Because the broadcast timing happened to overlap, the two have ended up being discussed as though they were one topic, but readers should note they are in fact separate matters.
