Falling Knife

Falling knife describes an asset whose price is collapsing so fast and so hard that any attempt to buy in before it stops falling is considered reckless. Traders borrow the image from a literal knife dropped point first: reaching out to grab it mid-air almost guarantees you get hurt, and reaching for a crashing chart works the same way.

The pattern typically shows a series of large red candles with little to no consolidation, often triggered by a specific shock: an exchange insolvency, a broken stablecoin peg, a failed protocol, or a wave of forced liquidations. Because nobody can reliably call the exact bottom while the drop is still in motion, buying "on the way down" frequently means the asset keeps sliding well past the entry price.

The 2022 collapse of Terra's LUNA token is the standard crypto illustration: as its algorithmic peg to UST unwound, LUNA fell from roughly $80 to fractions of a cent within days as new supply flooded the market. Traders who bought at $60, $30, or even $5, expecting a rebound, watched their positions go to near zero, a textbook falling knife rather than a normal dip.

Experienced traders generally wait for confirmation, such as a reclaimed support level or slowing sell volume, before assuming a capitulation low is in. Even then, a bounce can turn out to be a dead cat bounce rather than a genuine reversal, which is why the safer approach is simply to wait for a base to form before considering an entry.
