Short answer: the crypto fear and greed index gives one daily score from 0 to 100 that summarises market sentiment across bitcoin and the wider crypto market. Low readings mean fear, high readings mean greed, and the extremes are where it earns attention. It blends market volatility, trading volume, social chatter, bitcoin dominance and Google Trends data into one number. Treat it as a thermometer for crowd mood, not as a buy or sell trigger. It shows how jittery or euphoric the crowd is; your trading strategy decides what to do with that.
What goes into the score
The index is published once a day by its source. It is a weighted blend of six inputs, each measured mostly against bitcoin and converted into its own fear or greed reading before being combined.
| Component | Weight | What it compares |
|---|---|---|
| Market volatility | 25% | Bitcoin volatility and drawdown against 30 and 90 day averages |
| Momentum and trading volume | 25% | Current volume and momentum against the same averages |
| Social media | 15% | Volume and speed of crypto mentions on social platforms |
| Surveys | 15% | Polls of crypto investors; paused for long stretches |
| Bitcoin dominance | 10% | Bitcoin's share of total crypto market capitalisation |
| Google Trends data | 10% | Search interest in bitcoin queries and their wording |
Direction matters for each input. Unusually high volatility reads as fear. Heavy volume on a rising market reads as greed. Rising dominance counts as fear, because money is retreating into the largest coin; the guide on how bitcoin dominance is calculated and read explains why that ratio moves. The social and search inputs are coarse by design: they count attention, not opinion.
Reading the score bands
The number is simple; the bands are where ambiguity creeps in. The common reading runs roughly like this:
- 0 to 24: extreme fear. Volatility is high, volume is lumpy, forced selling is likely in progress.
- 25 to 49: fear. The crowd is hesitant and dips get sold rather than bought.
- 50 to 74: greed. Buyers are confident and pullbacks are shallow.
- 75 to 100: extreme greed. Attention peaks and new money arrives late.
Readings near 50 are unremarkable and rarely worth a decision. The information sits in the tails, and even there it describes conditions rather than forecasting price movements.
How the index has behaved at past extremes
The crash of March 2020 pushed the reading into single digits within days, as bitcoin fell violently and stayed wobbly for weeks. The 2022 bear market held the score in extreme fear for months, through the collapse of a large stablecoin and later a major exchange. Bitcoin's runs to record highs did the opposite, with the score stubbornly sitting above 75 while price kept climbing.
Two lessons follow. Extremes persist: a reading of 10 can be followed by a reading of 8 a fortnight later with price 20% lower. And the score bottom and the price bottom seldom land on the same day, because volatility spikes before the final low. Fear peaks early; greed peaks late.
A strategy checklist for using the index
The index belongs in the filter layer of a trading strategy, not the entry layer. Entries still come from price.
- Log the reading each day next to the bitcoin close, so you build your own chart of the pair.
- In extreme fear, prepare long setups and halve the size of any fresh short.
- In extreme greed, tighten stops on open longs and refuse to add.
- Wait for the reading to turn back out of the extreme, not merely reach it.
- Confirm with a structure signal from a rules-based bitcoin trading strategy.
- Note divergence: a score that climbs while price goes nowhere is a quiet sign of accumulation.
Picture a 50,000 account risking 1% per trade, so 500 per position. The index prints 12 after a 30% drop. Buying that first print is plainly tempting, but the checklist says wait. Five days later the score is back above 25 and a daily close reclaims the prior high. The trader enters with a stop 8% below, under the low of the fear period, so the position is 6,250 of notional: 500 divided by 0.08. The stop is a known distance rather than a hopeful one.
Limitations and common mistakes
- It is bitcoin-centric. The score can show greed while a particular altcoin is in disorderly decline.
- It updates once a day. Intraday the reading is stale, and in a fast session it is sluggish by hours.
- Inputs are patchy. The survey component has been paused for long periods, and social counts can be inflated by bots.
- Extremes last. The blunt rule "buy extreme fear" will squander capital in a bear market that stays fearful for months.
- Greed readings and chasing go together. The impulse behind a score of 85 is the one described in the guide on recognising FOMO before you enter.
One honest note: flipping positions on every swing of the index adds spread and commission cost to each crypto CFD trade, and those costs are unforgiving on a small account.
Where the index meets prop-firm loss limits
Extreme readings coincide with high market volatility, and volatility is what breaches evaluation limits. A 4% daily loss limit on a 100,000 account is 4,000. A bitcoin position sized for a calm 2% daily range can lose that in one session once the range doubles. An extreme fear print is telling you that doubling is under way. The practical rule: under 25 or over 75, cut size so a doubled range still leaves the daily limit intact.
Pivex runs crypto exposure as CFDs on BTC, ETH and SOL. The daily loss cap refreshes every session and the total drawdown stays fixed rather than trailing your equity. There is no deadline on the evaluation and weekend positions are permitted, which matters because crypto keeps moving on Saturday while the index keeps updating.
Crypto sentiment rarely detaches from the wider risk mood for long. Comparing an extreme reading with the FRED VIX series shows whether fear is specific to crypto or part of a broad risk-off move, which changes how quickly it tends to reverse.
Next step: keep a two-column log of the daily reading and the bitcoin close for a month, then mark where the extremes fell against price. That exercise shows how early fear peaks and how long greed lingers. When you want to apply it under a real rulebook, Pivex sets out its loss limits and reward terms up front. Sizing for a volatile fear day then becomes a calculation rather than a guess.
