Crypto Fear & Greed Index
Stock investors have seen the crowd's temper: the harder it falls the more they sell, and right at the top is when they chase hardest. Crypto amplifies that several times over. This index squeezes the whole market's mood into a single number from 0 to 100 — lower is more panic, higher is more euphoria. Take a glance and you'll know whether people are fearful or greedy right now.
When the mood hits an extreme, you need an account to act
"Be greedy when others are fearful" is an old line, but when the panic actually comes, anyone without an account ready can only watch. Get yours set up first — sign up to Binance with our invite code and shave your fees too.

How to read this number — stock investors feel it most
The index runs 0 to 100 in five bands: 0 to 24 is Extreme Fear, the market is all wailing and everyone wants out; 25 to 44 is Fear; 45 to 55 is Neutral; 56 to 74 is Greed; 75 to 100 is Extreme Greed, with the most chasing and the loudest "this time is different". It blends price volatility, volume, social-media buzz and market dominance into a single mood thermometer.
Buffett's line — "be fearful when others are greedy, and greedy when others are fearful" — is exactly how this gauge is meant to be used. When the index sinks into Extreme Fear, it's often the moment panic sellers are flooding out and the price has been hammered into a hole by emotion; when it spikes to Extreme Greed, it's often when buyers are most crowded and risk is highest. This is a contrarian lens, not a buy/sell signal — moods can sit in extreme territory for a long time, and trying to catch the bottom on the left side often catches a falling knife halfway down. Its value is the reminder: when you find yourself swinging between fear and greed with the market, stop for a second. To tie this mood logic to position sizing, see the position calculator and how stocks and crypto differ.
We looked back over a few days when the index dropped into Extreme Fear, and with hindsight they were often not far from a local low — but "often" isn't "always", and there have been times it kept falling after the fear. So our own use is restrained: treat it as a reverse reminder, keep a little extra calm when the mood is extreme, and never treat it as a buy/sell button. What really decides position size is the discipline you set in advance.
