alternative.me vs CFGI: Which Crypto Fear and Greed Index?

What Does Each One Measure?

alternative.me built the crypto Fear and Greed Index that made the format popular. It scores the market as a whole, weighted heavily toward Bitcoin, from a handful of inputs: volatility, market momentum and volume, social media, surveys, Bitcoin dominance and search trends. It updates once a day. CFGI runs the same 0 to 100 idea but scores each asset on its own, from 10 indicators, and refreshes every 15 minutes across 4 timeframes. Instead of one headline number, you get the mood of Bitcoin, Ethereum and 100+ other assets separately.

What the alternative.me Index Is

It is worth giving alternative.me its due: its index, launched around 2018, is the original crypto Fear and Greed Index, the one that popularised the whole concept for crypto and became the familiar default that most people picture. Its methodology is a weighted blend of five factors: market volatility (around 25%), market momentum and volume (around 25%), social media activity (15%), Bitcoin dominance (10%) and Google search trends (10%), with a surveys component that has historically been paused. It distils these into a single 0 to 100 number for the overall market, computed once a day, and because volatility, momentum and dominance are all read largely off Bitcoin, the resulting figure is effectively a Bitcoin-weighted gauge of the broad crypto mood. It is a clean, well-known and genuinely useful tool for a once-daily read of the market’s temperature, and its long history and prominence are real virtues. The questions worth asking are simply whether one daily, market-wide, Bitcoin-centric number is enough for how you actually invest.

The Per-Asset Difference

The single most important distinction between the two is granularity. alternative.me gives you one number for "crypto", a Bitcoin-weighted average that, by its nature, blends the whole market into a single mood and hides the divergences beneath it. CFGI scores 100+ assets individually, which means it can show you exactly the thing a single average erases: that one coin sits in Extreme Fear while another runs in Extreme Greed at the same moment. That divergence is real and large, the gap between the most fearful and most greedy major coins has reached 61 points. For anyone who holds or trades more than just Bitcoin, this is the difference that matters: it is far more actionable to know that the specific coin you own has hit an extreme than to know that "the market", dominated by Bitcoin’s mood, is mildly fearful. Per-asset scoring turns a single broad temperature reading into a detailed map of where fear and greed actually live across the market. CFGI also reads the stock market on the same scale, which the original does not attempt.

Which Should You Use?

For a single daily glance at overall crypto mood, the original index does the job, and its familiarity and long track record are genuine reasons to value it. If you hold or watch more than Bitcoin, or you act on sentiment intraday rather than once a day, per-asset scoring and a faster refresh are the differences that matter: one coin can sit in Extreme Fear while another runs greedy, and only individual scores reveal it. The two are not really rivals so much as tools for different needs, a broad daily gauge versus a granular, real-time one, and the right choice depends on whether you invest in "crypto" as a single block or in specific coins whose moods you want to read individually.
