noun | faw·ling nahyf
A falling knife is like when you see your favorite shitcoin dumping and you think "now's my chance to buy the dip!" but then it keeps dumping and you're left holding the bag like a sucker - it's a market that's in free fall, and trying to catch a bottom is like trying to catch a, well, falling knife. It's a good way to get rekt.
Example
"I tried to catch the falling knife on BitConnect when it was down 90%, thinking it was a once-in-a-lifetime opportunity. Turns out, it was a once-in-a-lifetime opportunity...to lose all my money to a Ponzi scheme. Press F to pay respects."
"Trying to time the bottom on a falling knife is like playing Russian roulette with your portfolio - you might get lucky and hit the jackpot, but more likely you'll just end up with a hole in your head and an empty bank account. Don't be a hero, just wait for the dust to settle."
