What is Falling Knives?
Crypto Glossary Definition
A term used to refer to someone buying an asset which is rapidly declining in price.
Why Falling Knives Matters
"Don't catch a falling knife" warns against buying an asset purely because its price has dropped sharply, on the assumption it must be "cheap" now — a steep drop can just as easily continue much further, and the phrase is a common counter to premature dip-buying.
Falling Knives in Practice
Suppose an altcoin that traded steadily around a certain price for months suddenly drops sharply after a negative development, losing a large portion of its value within days. A trader who missed the original run-up sees the lower price and reasons that, since the coin was worth so much more recently, it must now be a bargain, so he buys in immediately, expecting a quick bounce back toward previous levels. Instead, the selling continues, driven by more holders panicking and exiting as the price keeps falling, and within another week the coin has dropped even further below where he bought it. This is the classic pattern behind the warning 'don't catch a falling knife': a sharp decline doesn't tell you where the bottom is, and buying purely because a price has already fallen a lot, without any deeper thesis about why it should stop falling, is a common way traders end up buying into a continuing crash rather than a genuine reversal. Experienced traders who do buy during steep drops usually wait for some sign of stabilization first, like the price holding steady for a period or trading volume declining, rather than buying purely on the size of the drop itself, precisely because a knife in freefall can keep falling well past where it looks 'obviously' cheap.
