Buy the dip means nothing until you say which dip
What an extreme is, and why it matters
It isn’t magic and it isn’t a certainty. It is statistics. In those conditions, historically, the market tends to recover — which means that repeating the trade many times ends up in profit, not that the next one will go well.
And they are rare. In our archive, over 9 years, bitcoin closed at minus eight percent or worse 57 times out of 3,284 days: fewer than two a year. If you buy every five percent fall, you aren’t buying the extremes — you are buying the noise in between.
How you recognize one, in practice
The second is the speed: how far the price has fallen over a short interval. Not the size — the speed. A three percent fall in an hour says something different from three percent over a week, even though the number is the same and even though the chart, seen from a distance, looks identical.
When the two measures hit extreme values together, the odds shift. When only one of them does, it is nothing yet: it is the market going down, which by definition it does almost half the time.
The strength of the recent move on a 0–100 scale: below 30 is the standard oversold threshold, but in the crypto market the extreme starts below 20 and becomes rare below 10. The speed of the fall over short intervals: what counts is how fast the price fell, not how far. The two measures hold together, not separately.
Why fast crashes are different
It is a domino effect that feeds itself until the positions left to close run out. At that point the cause of the fall disappears, simply because it has run out of fuel — and what is left is a lower price with nobody forced to sell any more.
A leveraged position is closed out; the forced sale pushes the price lower; the lower price triggers more forced closes; the cycle repeats as long as there are positions left to close. When they run out, the cause of the fall exhausts itself.
It is why a ten percent drop over a few hours is a different kind of thing from a ten percent fall spread over three weeks. In the first case the derivatives market cleaned itself out; in the second somebody is leaving calmly, and whoever leaves calmly usually knows why.
The extreme can get more extreme
The practical consequence sits entirely there: buying during an extreme doesn’t mean buying it all at once. It means starting to build a position knowing you might have to buy more further down, and that the second part of the plan is there for exactly that.
Then there are three cases where the fall shouldn’t be bought at all. When it is slow and steady — two or three percent a day for weeks isn’t a dip, it is a decline. When the measures aren’t genuinely extreme. And when there is a real reason behind it: a new rule, an attack on a protocol, an exchange going under. There the technical indicators count for less than what happened.
The fall shouldn’t be bought when it is slow and gradual (two or three percent a day for weeks, which is a decline and not a dip), when the indicators aren’t at genuinely extreme values, and when there is a real fundamental cause such as adverse regulation, an attack on a protocol or an exchange failing.
How I use it
The advantage of proceeding this way isn’t in guessing the bottom. It is in avoiding buying when everyone is buying, and buying when everyone is afraid — which is the same thing said backwards, but with a criterion in front of it instead of an instinct.
And it is a statistical advantage, not a certainty: it works on repetition, not on the single instance. Anyone using it expecting the next trade to go well has understood the opposite of what is written here.
