This tool shows today's Crypto Fear and Greed Index as a gauge from 0 to 100, along with its official classification, running from Extreme Fear at the low end to Extreme Greed at the high end. Underneath the gauge you get yesterday's reading and the value from one week ago, because a single sentiment number with no history is close to useless. Direction usually tells you more than the level itself.
Like a handful of tools on this site, this one fetches live data instead of running entirely offline. The only thing that travels is the request for the index itself, made to alternative.me, the site that has published this index for years. Nothing about you goes anywhere: no wallet address, no holdings, no account, no API key. If their service is down, the tool says so rather than dressing up a stale reading as today's number.
How to use
- Open the tool and today's index loads automatically. No input is needed.
- Read the gauge position and the classification label, from Extreme Fear through the middle zones up to Extreme Greed.
- Compare today against yesterday's value and last week's value shown beside the gauge.
- Skim the components section to see what actually feeds the number.
- Check back tomorrow if you track it over time. The index updates once per day.
Why use our crypto fear & greed index?
The comparison values are the quiet feature I care most about. A reading of 30 after a week hovering around 55 tells a story of souring mood; the same 30 after a week stuck at 12 suggests fear is actually easing. Showing yesterday and last week next to today turns a static number into a direction, and direction is the thing sentiment data is genuinely good for.
The tool explains its own ingredients instead of presenting the index as an oracle. The score blends measures of market volatility, momentum and volume, social media activity, and Bitcoin dominance. Knowing that mix matters, because it means the index leans heavily toward Bitcoin and measures crowd behavior, not fundamentals or news.
Contrarians watch this index for one simple reason: crowds tend to be most fearful near local bottoms and most greedy near local tops. The old advice about being fearful when others are greedy is essentially what this index tries to put a daily number on. I treat extreme readings as a prompt to slow down and question my own excitement or panic, never as a trade signal on its own.
And I will be honest about the limits, because most pages covering this index are not. It is a sentiment summary, not a prediction machine. Markets can sit in Extreme Greed for weeks while prices keep climbing, and Extreme Fear can always find a way to get more extreme. Anyone claiming a single 0 to 100 number can time the market is selling you something.
Who is this tool for?
The morning gut check is how I use it myself. I glance at it with coffee, not because it predicts anything, but because it tells me the mood of the room before I read a single headline. If a decision I am about to make happens to agree with the crowd at an extreme, that alone earns it a second look.
Traders use the extremes as a discipline filter. If the gauge is deep in Extreme Greed and you feel the urge to size up, running the trade through our position size calculator first is a cheap way to let arithmetic argue with adrenaline.
Long term holders lean on it for the boring decisions: when to rebalance, when to take some profit off the table. Working out what an exit would actually return with our crypto profit calculator while the sentiment context sits on screen keeps that decision grounded in numbers rather than vibes.
Writers and newsletter authors grab the daily reading and the week over week change as market color. Pair it with live prices from our crypto price converter and you have the two data points most crypto market updates open with.
Frequently asked questions
A daily score from 0 to 100 summarizing crypto market sentiment, published by alternative.me. Low values mean fear dominates the market, high values mean greed dominates, and the far ends of the scale get the Extreme labels.
The publisher combines several signals: recent volatility, market momentum and trading volume, social media activity, and Bitcoin's share of total market capitalization. The exact weighting is set by alternative.me, not by this tool.
No, and I will not pretend otherwise. It describes the current mood of the crowd. Extreme readings have historically coincided with some turning points, but they have also persisted for long stretches while prices kept trending.
Because extremes of crowd emotion often accompany bad collective decisions. When everyone is euphoric there may be few buyers left, and when everyone is terrified sellers may be exhausted. Contrarians use the index as a prompt to lean against the crowd, carefully.
Once per day. The tool fetches the current value each time you load the page, along with the previous day and the reading from a week ago.
No. The tool requests the index values from alternative.me and that is the entire exchange. No account, no key, no wallet, nothing personal.
Because it largely is. Several components are measured on Bitcoin or on Bitcoin's dominance of the market, so sentiment on smaller altcoins can diverge from what the gauge shows.
You get a clear message saying the index could not be fetched. The tool never substitutes an old reading and passes it off as today's.
